Theories on firm mortality


The mortality of companies


Investigating the exponential age distribution of firms


The mortality of companies

We examine a comprehensive database of more than 25 000 publicly traded North American companies, from 1950 to 2009, to derive the statistics of firm lifespans. Based on detailed survival analysis, we show that the mortality of publicly traded companies manifests an approximately constant hazard rate over long periods of observation. This regularity indicates that mortality rates are independent of a company’s age. We show that the typical half-life of a publicly traded company is about a decade, regardless of business sector.

(Our results shed new light on the dynamics of births and deaths of publicly traded companies and identify some of the necessary ingredients of a general theory of firms.)

A. Public companies and lifespan

Publicly traded companies are among the most important economic units of contemporary human societies. (Alchian 1972Coase 1988Hannan and Carroll 1992, 2000Jovanovic 2001


<- As of 2011, the total market capitalization of firms in the New York Stock Exchange was 14.24 trillion dollars, comparable to the entire gross domestic product of the USA.

While researchers have devoted considerable attention to the distribution of firm size (Simon and Bonini 1958; Stanley, Amaral, Buldyrev, Maass, Leschhorn, Salinger and Havlin 1996, 1997a, 1997b; Axtell 2001), the distribution of firm lifespan has been the subject of far fewer studies (Coad 2010). Thus, despite the availability of much quantitative information, our understanding of the way public companies live and die remains limited.

B. Datasets, Definitions, and Survival biases

Arguments addressing the statistics of company lifespans hinge on the interpretation of the meaning of the death event for a company. In this paper, definitions of ‘birth’ and ‘death’ are based on the sales reports available in the Compustat database. 

-> firms may ‘die’ through a variety of processes: they may split, merge or liquidate as economic and technological conditions change.

i) Datasets

Data on publicly traded companies were obtained from the Compustat North America and Compustat Historical databases,  covering the period of 1950–2009 and contain most financial information for North American and overseas American Depositary Receipt firms reported in their income statements and balance sheets, filed to the US Securities and Exchange Commission. A total of 28 853 publicly traded companies are included in the database. From these, we excluded 2292 that did not report any sales over the 60-year timespan. We also noted that 6868 companies were listed (alive) either in 1950 or in 2009, with 160 of those companies reporting sales for the full 60-year span of the dataset.

ii) Definitions

We define ‘birth’ to occur not at a company’s founding, but rather when it first reports sales in the Compustat database. We take ‘death’ to occur in the year when a company stops reporting sales. For each company, we define lifespan to be the total number of years for which the company reports non-zero sales.

<- There are a number of companies that fail to report for several years between years of activity. Such cases of re-entry are not counted as additional new births or deaths; the additional years are simply added to the total lifespan.

-> This definition is similar to the Bureau of Labor Statistics Business Employment Dynamics measures of entries, which include mergers, takeovers and industrial reclassification

-> This broad definition of death will affect the conclusions we can draw from our data, as an instance of firm death does not necessarily connote failure (Carroll & Delacroix 1982).

* As a metric of mortality that is closely related to lifespan, we use the term half-life, defined as the time it takes for half of the firms in a given cohort to die (following the above definition of death).

* For survival analysis, this half-life corresponds to the age t by which the cumulative mortality fraction M(t) = 0.5 (50%).

iii. Survival biases and subsampling

The historical data on Compustat database do have problems of survival bias (Ball & Watts 1979): almost no firms die in the first 20 years of the dataset. To account for the effects of this bias, we ran our analysis both on the entire dataset and on a set limited to firms reporting sales between 1975 and 2009. A comparison between analysis of the entire sample and this reduced set suggests that the effect of survival bias is limited. This is likely because the first 20 years comprise a very small proportion of the entire dataset.


C. Theory of the firm

There is a great diversity of perspectives on a theory of the firm, focusing on different aspects of their costs, organization and evolution. 

Economists such as Coase [1988, 1937, 1960] and Williamson [1991; 1985] proposed that firms exist in order to minimize (positive) market transaction costs involved in the production of goods and services. In situations when there is particular specificity of goods and services exchanged between two economic agents, such transactions may be best organized internally to an organization rather than negotiated in the open market (Alchian 1972, Williamson 1985 ).

-> As such, firms may split, merge or liquidate in response to economic agents evolving new and better ways of dealing with the various costs and revenues of production and exchange (Arrow 1969; Grossman and Hart 1986; Hart and Moore 1990; Tadelis 2002). 

-> Therefore, at least on the average, the merger of existing companies should be approximately neutral in terms of the balance between costs and benefits. ??

(However, this relatively simple picture becomes more complex in the light of behavioural studies of the impact of decision-making and management practices on the growth and viability of actual firms.)

D. Organizational ecology

In the framework of organizational ecology, companies are seen as units of selection in markets and their longevity is the result of their successes of learning and adaptation in these environments (McPherson 1981, 1983).

Organizational ecology has often suggested that the mortality rates of firms are age-dependent (Hannan and Carroll 2000).

liability of newness (Stinchcombe 1965): young establishments experience higher mortality rates, supported by observation of US manufacturing plants (Dunne, Roberts and Samuelson 1989), Argentinian and Irish newspaper companies and other types of businesses (Carroll & Delacroix 1982).

<- Theoretical grounding draws from the adaptive requirements of market entry; it takes time for young companies to gain the competencies and build relationships that will ensure their ability to survive (Hannan 1998; Freeman, Carroll and Hannan 1983). + New companies are likely to be smaller and less experienced and thus more susceptible to market shocks (Hannan 1998). Knott & Posen [2005] stress the evolutionary character of these arguments by suggesting that liability of newness is evidence for market-based selection.

However, liability of adolescence is also seen. In a study of West German business enterprises, Bruderl & Schussler [1990] find that companies are, in fact, protected from mortality in the immediate period after founding.

<- This liability of adolescence likely results from the buffer a firm acquires via its capital endowment at birth [Hannan 1998], which is also a characteristic of firms that have recently entered financial markets. <- As their initial capital stock is expended, less profitable companies become more vulnerable to environmental changes in market conditions.

And liability of senescence or obsolescence: mortality rates increase as companies age.
1) liability of senescence: as companies age, they accumulate rules and stagnating relationships with consumers and input markets that render them less agile and that re-configuration is increasingly expensive (Henderson & Clark 1990);
2) liability of obsolescence: environmental requirements change over time and that, although firms may improve in competence and efficiency with age by becoming more specialized, these specific adaptations also increase the companies’ risk to new kinds of external shocks that will inevitably beset them.

** Coad [2010a] has argued that these assorted liabilities constitute small deviations, at the tails, from an aggregate lifespan distribution that is generally well approximated by an exponential distribution. <- This proposition has been confirmed in Italian, Spanish and French firms (Navaretti, Castellani & Pieri 2014

<<- the statistical patterns of firm entry and exit will affect the distribution of firm sizes in any given year and set its form and temporal stability (Coad 2010bAmaral et al. 1997a).  <<- thus a better understanding of the mortality risk of firms is necessary to generate new insights on the empirically observed scaling regularities in firm size frequency distributions??? (Amaral et al. 1996; Axtell 2001)

(the existing literature on firm survival has often focused on tracking small samples of firms in specific industries. )


We confirm the hypothesis of an approximately constant mortality rate, finding that the exponential distribution of firm lifespans holds across business sectors and causes of mortality. We apply survival analysis to estimate in a variety of ways that the firms in our dataset have a half-life of approximately 10 years, regardless of age.

Investigating the Exponential Age Distribution of Firms

The age distribution to be an interesting feature of industrial structure. The age distribution may be of direct interest in theoretical models of the firm size distribution, as well as providing indirect information on a number of phenomena such as entry rates, survival rates, and possibly even the age of technology used in production.

However age distribution of a population of firms has barely been investigated in empirical work (only Coad and Tamvada 2008 focus on census data covering around 700’000 small scale firms in India & Segarra et al. 2008)focus on a sample of about 85’000 firms taken from the Spanish Mercantile Register).


Figure 2 shows that, even in a sample of small businesses, these firms have very different ages. Most firms are relatively young, but some are extremely old.

The shape of the distribution appears to follow an approximately straight line with negative slope over most of the support. Given that the y-axis is expressed in logarithms, this straight line of negative slope suggests that an exponential distribution would be a valid approximation of the empirical age distribution.

In later sections of the paper, however, we focused on situations in which the exponential gave only an imperfect representation. In contrast to the exponential benchmark, we observed that young establishments seem to be especially numerous, the oldest firms seem to be exceptionally long-lived, and at the disaggregated level of certain specific sectors we can observe a particularly irregular age structure

<- i) Concerning the large number of young establishments, it could be that this excess weight in the age distribution corresponds to over-entry by inefficient establishments who exit shortly afterwards (the case of ‘hopeful monsters’); excess entrepreneurship undertaken by overoptimistic entrepreneurs. (Santarelli and Vivarelli 2007) ->> To the extent that departures from the exponential benchmark among young establishments represent over-entry, then the exponential age distribution could be used to gauge the magnitude of this phenomenon.

<- ii) Departures from the exponential benchmark in the case of the oldest firms also have a ready economic explanation, in that certain long-lived firms, and especially family firms, do not pursue economic rationality in the sense of maximization of expected profits, but instead they may seek to maximize their chances of survival (e.g. by pursuing risk-averse strategies).

<- iii) the exponential distribution may not always be a valid heuristic at the disaggregated level of individual sectors, e.g. the international airline industry. In contrast to the smooth shape observed at the aggregate level, the age distribution of this particular sector is much messier and displayed conspicuous multimodality.

** The exponential is still a useful benchmark for understanding the age structure of industries. For example, we suggest that theoretical models of firm entry, exit, and industry evolution would do well to generate an exponential age distribution as part of their output, even though the empirical data is not exactly exponentially distributed.

(other candidate distributions such as the Pareto, or intermediate cases (between the exponential and the Pareto) could also be fruitfully investigated.)


Firm Turnover and Competition





Fortune 500 Turnover


We find that, while annual turnover on the list has, on average, increased since the early 1980s, it doesn’t quite mean what many people think it means.

It’s easy to paint a narrative around these numbers that coincides with the Great Moderation and the productivity revolution of the 1990s and early 2000s. But reality isn’t so simple.

1. Turnover among big companies is not a new phenomenon.

The late 1950s, as mentioned, experienced moderately high levels of turnover (at least compared to subsequent periods). Prior research has revealed considerable churn among big companies in the early decades of the twentieth century as well.

2. Higher turnover in the 1980s did appear to reflect value creation as corporate conglomerates, ravaged by inflation and competition, were taken apart and remade into separate, more efficient companies.

But, in the 1990s, higher turnover reflected (a) methodological changes in how the Fortune list was compiled, and (b) a mergers and acquisition boom, concentrated in a handful of sectors, that destroyed perhaps as much value as it created. /Turnover is less a broad economic trend than a discrete temporal and sectoral phenomenon


Fortune 500 changes reflects:

1.a kaleidoscopic process of sectoral change and greater efficiencies at the level of individual firms

2. some less sanguine economic developments, which includes the downside of higher volatility—the high M&A volume in the late 1990s included the largest number of the worst deals of the past thirty years—and the deleterious implications for consumers and households.

3. it appears as if performance among the Fortune 500, as measured by return on equity, did not necessarily improve and, if anything, became more volatile over time.


Schumpeter’s ghost: Is hypercompetition making the best of times shorter?

At the center of Schumpeter’s theory of competitive behavior is the assertion that competitive advantage will become increasingly more difficult to sustain in a wide range of industries.   (recently resurfaced in the notion of hypercompetition.)

This research examines two large longitudinal samples of firms to discover which industries, if any, exhibit performance that is consonant with Schumpeterian theory and the assertions of hypercompetition.

We find support for the argument that over time competitive advantage has become significantly harder to sustain and, further, that the phenomenon is limited neither to high technology industries nor to manufacturing industries but is seen across a broad range of industries.

We also find evidence that sustained competitive advantage is increasingly a matter not of a single advantage maintained over time but more a matter of concatenating over time a sequence of advantages.


Papers on Firm death



The case of disappearing firms: Death or deliverance?

The case of the disappearing firms: Empirical evidence and implications

Death is not a success: reflections on business exit



The case of disappearing firms: Death or deliverance?

Many theories about performance, competitive advantage, legitimacy, and leadership rest upon a core assumption that firms, at least some of them, have long, perhaps limitless, life-spans. Long-term survival is not seen as merely a random outcome or an unattainable goal.

This paper surveys a broad set of empirical findings about firms’ life-spans. It is consistently revealed in the empirical literature that the VAST majority of firms, even large firms, survive relatively short periods.

Specifically, this paper makes three contributions to the organizational literature.

1. clarifies the importance of firm’s life-spans as a pivotal research topic
2. appraises a broad range of research about the survival of firms
3. presents general themes about observed life-spans in relation to concepts, measurement, and theoretical issues

A. Motivation, definitions, conceptual and empirical issues involving life-spans of firms


In thinking this way scholars subscribe, perhaps inadvertently, to a ‘meta-theory’ about success and failure. If a firm’s life ends, it must be the result of defects, of competitive mistakes, of managerial failures, inferior resources, and so on. Put simply, the failure of firms is not random, accidental, normal or inevitable, as it is in human life-spans.

How many firms survive? How long do firms survive? Who survives? Is (long term) survival the planned result of first-mover advantages, or large size, or market structure, or competitive advantage, etc?


Although the usage of the term ‘firm’ may seem straightforward in conventional business parlance, pinpointing a research definition involves difficult issues.Are firms identical to business organizations? What about subunits and merger activities of larger organizations? How do size, control, and ownership affect the definition? Any of these definition aspects may have a material impact upon ‘counting’ firms.

According to US Census Bureau, ‘A firm is the largest aggregation of business legal entities (enterprises or companies) under common ownership or control … typically corporations, partnerships, Lilacs, or sole proprietors.’

iii. definitions-large firm and data

Under the Census Bureau definitions, there were roughly 6 000 000 firms in the United States in 2001.In empirical research, researchers often think exclusively in terms of very large businesses. There are a vast number of studies involving databases such as the Fortune 500, Fortune 1000, Standard & Pours, NASDAQ, Compustat, Product Impact of Marketing Studies (PIMS), Thomas Register, and so on. All of these sources focus exclusively on a few thousand very large firms, not 6 000 000 firms.

In a statistical sense, the 500 and the 1000 are essentially outliers. Such studies underestimate the number of competitors, hazard rates, disappearance rates, and exit rates, while over-estimating median life-spans, growth rates, role of mergers. Because of their unusual large size, their prosperity, their prominence in the business press, and their leading position with researchers, these firms are simply in a class of their own.

iv. definitions-disappearing and failure

In business parlance, disappearance is related to failure, dissolution, or exit, conceptually broader than failure, because failure only means bankruptcy, shutdown, dissolution, or discontinuance

In addition to outright failure, fundamental changes in ownership and management—changes in identity, mission and governance—cause firms to disappear even where brand names, assets, and operations superficially continue unchanged. Firms disappear through mergers, acquisitions, and divestments. (the two are highly correlated in empirical studies (Baldwin, 1998; Geroski, 1995))

Merged firms disappear in a most fundamental sense, because they lose their independence, they lose control over basic choices about as mission, they lose control over their finances. Although changes in ownership are often ignored by scholars, their consequences are significant for firm behavior and markets (Caves; 1998; Weston, Siu, & Johnson, 2001).

To summarize, the disappearance of a firm means that something basic has changed, an identity has been lost—whether or not a name or a brand continues to exist. Because some of these changes are difficult for researchers to identify, many studies over-estimate life spans, survival, hazards, and related variables. The rate of disappearance is sensitive to definitions, data bases, samples and measurements. 

vi. Empirical issues-Incomplete life spans

Some firms survive past the ending dates for the research, rendering calculations, such as average life-spans, incomplete and biased. -> A better measure, one seldom used, is median life-spans. When means are misleading, medians can be calculated to more accurately reflect the data. (not available for large firms)

B. Empirical research findings about disappearance and life-spans

We reviewed a total of 240þ relevant documents, covering a broad range of sources, including different academic fields (technology, entrepreneurship, Strategy, Marketing, Sociology, and Organization) as well as different forms of research, such as academic studies, public information, and independent reports. <- many concepts are related to firms’ disappearance rates, failure or mortality rates, exit, entry, and life-spans per se.

In general, these findings show that American business firms are numerous yet fragile. They enter and exit most industries in large numbers. But from a combination of poor decisions plus competition, the vast majority of new, entering firms soon disappear. But, this is not simply an issue about small firms. Even large firms do not enjoy a median life span anywhere near a human person’s life span.

And if one carefully reviews the research literature, it is difficult to square empirical findings against notions about sustainable advantage, corporate leadership, first-movers, or adaptive change.

i. Entrepreneurship/federal data

Using Census data, Birch (1987) claimed that two-third of net-new-jobs generated by the US economy were attributable to ‘small’ firms.

‘Small Business Data Base’ (SBDB, 1998) painstakingly tracks businesses in the US.

スクリーンショット 2016-10-28 0.21.20.png

Using the SBDB, Audretsch (1991, 1995a) studied the innovative propensities of small firms across a wide range of sectors. In general, about 44 per cent of larger startups survived 10 years, whereas only 31 per – cent of smaller startups survived ten years (1995, pg 92). The highest 10-year survival rate for any sector was 72 per cent for large instrument firms.


Boden (2000) studied three broadly defined industry groups—goods, services, and information. Boden estimated the following median life spans: 4.49 years for goods-producing firms, 4.50 years for services providers, and 4.47 years for information-technology firms. 

Dunne, Roberts, and Samuelson (1988b, 1989) used Census of Manufactures data from consecutive 5 year time periods between 1963 and 1982. They confirmed that exits are chiefly comprised of new, small firms. In addition, entry and exit varied greatly across time and across industries, suggesting industry-specific factors may govern these processes. During any 5 year time-frame, entry and exit are strongly correlated, showing that entrants and exits are mostly identical firms. Low market-share and small size were identified as the biggest predictors for exit. Significantly, DRS also noted that rates of entry and exit were increasing during each time period they studied and the relative size of entrants was decreasing.


Summary. Federal databases represent one of the most extensive, inclusive and reliable sources for research on business formation, entry, exit, survival, etc. New firms begin their lives under-financed and vulnerable; almost all entrants are too small—far below minimum efficient scale. Larger entrants have better survival rates and longer life-spans, but not as high or as long as one may expect. Median survival rates of 5 years or less are typical. Average survival rates running between 4 to 10 years are common.

ii. Technology studies

they share a preoccupation with technological change as the driving force explaining industry and organizational change. They study innovation, first-mover advantage, dominant designs, technological trajectories, discontinuity, creative destruction, etc. These studies are useful in our review because many of them include detailed accounts of the entire history of important industries.

Utterback and Utterback et al. (1978, 1996) put forward an explanation of the emergence of dominant designs. They found firms who tried to maintain a traditional business while simultaneously starting a revolutionary business nearly all failed.

Anderson and Tushman (1990); Tushman and Anderson (1986) studied several industries, including minicomputers (1956–1982), cement (1888–1980), glass (1893–1980), and airlines (1924–1980). Both entry and exit were erratic and unpredictable.

Later studies of airlines (after deregulation) and computers (after 1980) showed increasing rates of turnover, exit and outright failure (see Miller & Chen, 1994), consistent with an increasing-turbulence environment.

On a broader level, Gort and Klepper (1982) studied 46 industries. The average shakeout during Stage Two was 53 per cent. They also presented evidence showing that the average time required for an industry to reach its peak number of producers, has been falling. That finding, especially across 46 industries, lent additional support to the idea that change is accelerating, that exit rates and fatalities are increasing, and that industry life spans are probably decreasing.


Summary. Lifecycle theories find significant empirical support but not universal confirmation (Iansiti & Clark, 1994). life-cycle models entail a surprising number of valid empirical patterns: entry by innovators heralding creative destruction; large numbers of firms enter and quickly exit; one severe shakeout; and finally the endgame converges on an oligopoly. The life-cycle model inherently carries a implication that the vast majority of entrants to any industry must fail (or exit), especially over a long-term. Therefore, technology studies reinforce the case for short life spans that was shown through the Entrepreneurship data (above).

iii. Ecology studies

Population Ecology measures variables such as exit, entry, mortality, and hazard rates, and are hyper-vigilant regarding the conceptual and measurement issues.

Aldrich (1979, 1999) estimated US business formation and business failure between 1940 and 1962 at about 3 400 000 new firms created and 2 800 000 discontinued per year. He reported that between 1910 and 1980 the number of US railroads declined from 1250 to merely 10 major firms.. For railroad firms, both the expansion and the exit periods involved astonishing disappearance rates.

Many other studies highlight industries where long-term mortality rates have been exceedingly high, such as automobiles, airlines, telephones (Barnett, 1990), discount retailers, savings and loan banks, etc.

Carroll and Swaminathan, studied strategic groups in the American brewing industry (1991). In 1880 the record showed 2474 brewers in the US. By 1980 only 45 survived. Many of those who disappeared were regional or local.

Hannan and Freeman (1987) investigated newspapers in the San Francisco Area.During the period they studied, 1840–1975, about 2179 total papers were founded,about 200 remained. In addition, they studied semiconductor manufacturers.1197 entrants between 1946 and 1984, 302 firms in 1985. Half of the entrants lasted less than 3 years. This study is especially important because many of the entrants were relatively large firms, or divisions of large firms. It shows that large-scale entry does not guarantee survival or long life.

Dowell and Swaminathan (2000) studied the US Bicycle industry between 1880 and 1915, when the industry experienced tremendous turbulence. 607 firms in 1898 had just 14 firms in 1904, a reduction approximating annihilation of a whole generation of firms in just 7 years.

Baum (1996) reviewed 20 years of PE research. The results are superficially consistent with notions about organizational ‘senility and rigidity’: whereas initial increases in age are correlated with decreased failure rates, ‘old’ age is often correlated with increasing failure rates.

However, research on organizational change (‘structural inertia theory’) have produced only mixed results (Aldrich, 1999). It is accurate to state that mortality risks increase for very old organizations, but the source(s) of those increased risks remains unclear.

Summary. Population Ecology studies report high mortality rates, similar to other findings (above). Failure rates are correlated with newness, size, and market-niche density. Moreover, mortality rates increase in organizational old age.

iv. Entry, exit, and mobility in economics research

Geroski (1995) reviewed empirical research on entry, exit, and failure. He found that smallscale entry is widespread in most industries. Entry comes sporadically, in ‘bursts’ or ‘waves,’ that are not correlated across industries, bursts that do not result from macro-economic shocks. More importantly, most exits result from economic distress. Entry and exit are highly correlated (0.5 to 0.7). Apparently, for many industries, entry is easy but survival is hard.

Caves (1998) reviewed turnover and mobility among firms. Caves defined turnover as, ‘entry and exit + mobility+ changes in control’. 


/Mobility: He shows the variance of growth rates e diminishes with greater size.Mobility seems to be independent from overall growth rates, cycles, firm size, investment patterns, macro-economy, and directionality of demand changes in the industry – many gainers in contracting industries as well as many losers in expanding industries. The facts imply limited life spans for all firms, large as well as small.
/ Entry rates and survival: About a decade after entry, continuing firms are looking at a 5–7 per cent hazard rate (the expectation of failure during the next year). These hazard rates increase when studies include progressively smaller firms in their sampling.
/ Entry and exit through control changes: Economists usually regard control changes as having no economic importance. Caves argues that control changes signify more than simply name changes, that control changes have real and important economic consequences. Caves contends that control changes can lift the productivity of large plants and greatly expand the size of productive small plants. Control changes must be included as part of industry dynamics. This reinforces our argument that control changes are real strategic changes, that they signal the disappearance of firms. Moreover, an active market for control implies that inefficient or vulnerable firms will soon disappear.

Agarwal and Gort (1996); Agarwal (1997) analyzed survival rates for entrants to 33 product markets, including large 3435 firms. They found hazard rates rising until firms reached ages 18–22. Therefore in a mature market, age and survival follow the typical positive correlation, similar to what PE would predict. However, an increase in hazard rates eventually takes hold of firms. Agarwal and Gort also calculated the ‘Mean Residual Life of Firms.’ – given a specified age how many additional years of life can be expected. Residual lives ranged from 5.8 years to a maximum of 14.6 years.


Summary. Economist’s studies of entry and exit, although largely fixed on manufacturing industries, provide important information relative to firms’ life spans: a vast majority of entrants begin far below minimum efficient scale; entry comes in ‘bursts’ or ‘waves’ unrelated to measured demand that inter-industry differences in profits don’t account for. These findings are consistent with the vision of an environment full of uncertainties, surprising spurts of growth and dramatic reversals—an environment where long term survival is problematic.

C. Large firms’ life-spans, in comparison to small, firms or ‘average’ firms

Are large and long-lived firms merely freak events, or do they represent some normal trends?

In 1987 Forbes Magazine reviewed their first ‘Forbes 100’ list and compared it to their 1887 list. Of the original group, 61 firms had ceased operations, 20 had been acquired or fallen out of the top 100, and only 18 firms managed to stay in the top 100. But the 18 did not perform well, data shows only GE survives. 

According to Census data, death rates ran high, 8 per cent, 10 per cent, and 9 per cent for firms employing 500 persons (include all US large firms) during the years 1995, 1996, 1997, respectively. Considering that these data cover mere one-year periods, these rates are quite large.


– Dow Averages: Of 20 Dow Industrials listed in 1920, only 2 remain on the Dow today, ATT and GE. (Pierce, 1995),
– Fortune 500: One-third of Fortune 500 in 1970 ‘disappeared’ by 1983. During the 1980s, no fewer that 113 of the 500 firms were acquired (Collins, 2001).
– S&P: The S&P averaged about 1.5 per cent annual turnover in 20s and 30s, but in 1998 the turnover rate in the S&P 500 had increased to 10 per cent. Annual S&P turnover, as a rolling 7-year average for whole 20th Century, is increasing. The average lifespan of S&P companies has been falling since about 1930, to less than 15 years today. (Foster & Kaplan, 2001).
– Geus (1997) reported findings from internal studies at Shell. His information placed the average lifespan of multinational firms at only 40–50 years.

Private research

Collins (2001) looked for firms that made a transition, from ‘good to great.’, Starting his research in 1980, his team eventually cut 1435 firms to merely 11. 

Foster and Kaplan (2001) compiled a database of 1000 large firms in 15 industries to search for patterns (did not include diversified companies or industries with overwhelming dominant firms, such as Autos) across four decades. Only 160 of 1008 companies survived from 1962 to 1998.

Weston show that the GNP share of the largest 200 firms has declined since 1970,ranges from 30 per cent to 40 per cent in US.

Mueller (1986) investigated a sample of 1000 large firms, 1950–1972. He observed stable market leadership in only 44 per cent of industries he studied. Out of 1000 firms, only 583 were still operating in 1972; 384 had been acquired.  

In addition to first-mover research, studies show that dominant shares decline: Shepherd (1997); Baldwin, (1998); Geroski (1995); Caves (1998); Caves, Fortunato, and Ghemawat (1984); Davies and Geroski, (1997); Elzinga and Mills (1996). Ferrier and Smith (1999). Specifically, Weiss and Pascoe (1983) found industry leaders dethroned in 39 per cent of industry segments they studied.


Perhaps mergers and acquisitions provide a back door escape from the specter of disappearance, but only for big firms . (according to the SBA (1998, 2000) only 2.6 per cent of US firms were involved in mergers)

Healy, Palepu, and Ruback (1992) studied post-acquisition performance in the 50 largest mergers US between 1979–1984 using lots of complex controls. They found that merged firms did more restructuring than comparable firms. Large firms did not just acquire firms; they also divested units, creating new firms. In 1990s divestitures represented about 35 per cent of M&A activities (Weston et al., 2001). Many studies report limited gains to acquirers and rapid divestment of acquired firms (Anslinger, & Copeland, 1996; Bradley, Desai & Kim, 1983; Caves & Porter, 1978)).

Dunne, Roberts, and Samuelson (1988a, 1989) used the Census of Manufactures, covering 1963–1982 387 two-digit industries. In general, diversifiers did not enter with new plants, they bought existing capacity. Diversifying entrants obtained high initial market shares, grew faster after entry, and had higher survival rates than small firms.

Baldwin (1998) reported many firms who entered by acquisition, soon exited—10 per cent in the first year. The cumulative exit rate of acquirers was about 60 per cent after 9 years. After 10 years, the hazard rates of Greenfield startups, acquisitions, and continuing firms all converge around 5 per cent.

Summary. surveying across many academic fields we find consistent indications that failure rates are increasing, even for large firms, that large firms face more turbulence and more challengers today than 50 years or 100 years ago. These trends all imply shrinking average life-spans. Based upon the research cited above, we could venture a ballpark estimate that medium-size and large-firms are approximately 20 years old and they can probably expect to survive another 20 yearsAll in all, large firms do not occupy a separate universe where marginalization, merger oblivion, failure, bankruptcy, and dissolution do not apply.

D. Themes, Puzzles, and Implications of Disappearance and life spans

Theme 1. The odd behavior of business firms

It’s widely known that a vast majority of small firms enter haphazardly, operate at an undersized, inefficient scale; and they fail (exit) at a prodigious rate. There is a strong case that newness, small size (in employment or capital) and associated inefficiencies all contribute to rapid failure. A majority of these firms cannot continue operations for 5 years, much less provide income during an entrepreneur’s working lifetime.

Theme 2. Over time the failure rates of acquired units converge toward the failure rate of new entrants

Diversified firms and large-size entrants, especially those with related experience, incur lower hazardrates, perhaps on the order of half the hazard rate of newly-founded firms. Even so, empirical research finds excess, illtimed entry and high exit-rates for subsidiaries, divisions, and strategic business units. As studies like Biggadike (1979), Yip (1982), and Robinson et al. (1992) found that the expected response to entry (increased output, ads, retaliatory pricing, etc) was highly selective or even entirely absent.

-> The results of real mergers, acquisitions, and allied activities do not comfortably fit a strategy framework (as Porter, 1980) or popular visions of entrepreneurship (Bhide, 2001).
-> Given large firms’ experience, their financial muscle, their vast core competences, giant strategic assets, and so forth—why aren’t large firms more successful at diversifying entry?

Theme 3. Entrants cannot resist an impulse to join an industry shakeout

Theme 4. The bigger they are the harder they fall: The MBA and the NBA

As a result of competitive mistakes and economic distress, large firms have an unimpressive average life-span. Despite their size, their vast financial and human resources, average large firms do not ‘live’ nearly as long as ordinary Americans. Therefore, setting out sustainable competitive advantage represents an elusive goal as achieving the combined goals of high growth, highperformance and long term survival is truly RARE.

(In statistical terms, outliers are usually viewed as a ‘problem.’ They violate assumptions etc. Therefore, outliers are routinely discarded because they distort variances and central tendencies.What would be the relevance of studying high-performance or sustainable advantage among US auto firms now, when only two firms remain—Ford and GM?)

Theme 5. Disappearance and design

As industries age, the proportion of ‘disappeared’ firms rises compared to the number of continuing firms. In a mature oligopoly, life-spans stabilize and the variance of life-spans becomes tighter.This pattern is tied to the shape of growth curves, industry-life-cycles, oligopoly, and empirical observation.

Theme 6. Time, and performance

Wiggins and Ruefli’s (2002) by using Compustat PC Plus, created a huge sample of 6772 (large) firms, from 40 industries, plotted across overlapping time periods up to 25 years. Their dependent variables were Tobin’s Q and Return-on-Assets, defining ‘sustained competitive advantage’ as a 10-year period of above-average performance for either dependent variable. During the entire 25 year period, about 5 per cent of firms achieved one 10 year stretch of superior ROA returns. Only 2 per cent of firms achieved any 10-year period above average Q. If the period is extended to 20 years, only 4 firms met the Tobin’s Q criterion! Although their study does not directly tell us anything about life-spans (they only studied 25 year survivors, not firms that disappeared), it does illustrate the consequences of longer time periods for organizational variables. Consistent with other authors, such as Mueller (1986) and Baldwin et al. (1995), their data show a broad pattern of regression toward the mean

Theme 7. Increasing turbulence

Although we did not review industry turbulence per se, we found considerable evidence pointing toward increasing turbulence, taking the form of increasing entry rates and increasing exit rates across a broad range of industries. It is not much of a stretch to suppose that increasing globalization, technical advances, and added pressures from investors could combine to create a very dangerous competitive landscape, one where thoughts of sustainable advantage are purely fantasy


The case of the disappearing firms: Empirical evidence and implications

Stubbatt and Knight’s idea: if the overwhelming majority of organizations have relatively short life spans, then the meta theory is misguided in believing managers make a difference.

In order to establish the life span of most organizations, they review ‘243 relevant documents’ that provide empirical accounts of organizational survival and disappearance.

-> They conclude that very few firms survive even a few years and that even successful firms rarely get beyond four decades. Further, the life span of firms is shrinking in the face of competitive pressures.

–>> The high probability of failure facing new ventures is already well established by entrepreneurship text  and organizational ecology. Organization theorists, similarly, for some time have observed the high ‘hazard’ rates confronting new firms and have explored the liabilities of newness and of adolescence. 

–>> the most interesting observation, however, is that almost all firms have brief lives and that established and successful corporations are subject to high failure rates. Is it true?

A. The Notion of ‘Disappearance’

For them, the endpoint of a life span is ‘disappearance.’ It covers many things from bankruptcy, mergers and acquisitions or the conversion of a closely held company to a limited corporation. 

<- It is important to separate these different meanings of disappearance because Business failure implies that managers were ineffective or perhaps irrelevant, while Mergers and acquisitions, on the other hand, might be the outcome of managerial prescience.

-> Sometimes, a firm acquires or merges with another in order to shift its scale or scope of operations, or in response to changing social expectations. For example. Green and Black, an extremely successful ‘fair trade’ cocoa company ‘disappeared’ when it was acquired by Cadbury Schwepps as the latter company repositioned itself to capitalize on the emerging consumer movement to support socially responsible businesses. Similarly, Price Waterhouse and Coopers & Lybrand merged to gain the geographical scale necessary to service the very largest transnational corporations.The entrepreneurship literature also talks about ‘serial entrepreneurs’ who start up businesses, bring them to success and sell them.

–>> Our key observation here is that ‘disappearance’ is not an unambiguous term. Firms disappear for different reasons. If our concem is to infer the role of managerial agency, then we need to distinguish between disappearance arising from poor or irrelevant management (what we might simply call organizational ‘death’), and disappearance that results from managerial prescience (organizational ‘deliverance’).

e.g. PricewaterhouseCoopers is the largest global accounting firm, ‘Legally,’ it began life in 1998. But, for us, PricewaterhouseCoopers is the consequence of managerial prescience on the part of the two legacy firms. These legacy firms did not simply ‘disappear’; they delivered themselves into a more effective firm for the 21st century. 

B. The Extent of ‘Death’

 40 per cent of the 100 largest consulting firms in the world existed in one form or another 50 years ago. All 10 of the world’s largest law firms pre-date 1950 and four of them trace their origins into the 19th century. Here we are defining survival as continued commercial activity irrespective of mergers or changes of name or ownership form. 

Some of sources cited by Stubbart and Knight hint that the life span of many organizations may well be longer than they suggested.

i. Foster and Kaplan (2001) ‘s study, conducted by McKinsey & Co., reports on 1008 companies over a period of 38 years only 160 remains. However,only 249 firmswere included in the database in 1962,the survival rate of firms in the 1962 cohort was 160 of 249 firms, or 64 per cent.

ii. In more scholarly but dated analysis by Mueller (1986) of the largest 1000 firms in the US between 1950 and 1972, he found that 58.3 per cent were operational over the full period and that only 1.9 per cent had been liquidated. The remaining 38.4 per cent had been acquired. Moreover, it is rtot the case that acquired firms were failing: ‘We conjecture that from 1952 to 1972 relatively few of the companies that were acquired faced immediate bankruptcy had they not been merged’. On the contrary, an earlier study by Mueller found that acquired firms were equally profitable to similar non-acquired firms.

->> sufficiently large numbers of established firms do survive for lengthy periods, and that managers probably have something to do with which firms survive and which do not.

Nevertheless, firms may differ as different survival and disappearance rates across industries. The professional service firms operate in very low capital intensive settings and survival may be easier than in industries where capital is more pronounced. 

Another possible source of variation in organizational survival and performance is ownership form. Most of the materials show bias to the limited liability, publicly traded corporation, while other ownership forms exist (Greenwood & Empson, 2003; Hansmann, 1996). Recently, Miller and Le-Breton Miller (2005) highlighted how family-controlled businesses ‘vastiy out survived’ non-family competitors. They report data on forty large, family-controlled businesses, of which more than half ‘had survived for over a century’. 

And international comparisons. Stubbart and Knight pragmatically restricted themselves to US data, but the literature on ‘varieties of capitalism’ (e.g.. Hall & Soskice, 2001) would suggest there may be significant variations between countries in the life cycles of organizations

->>Is the US, more vulnerable to high failure rates because of its widely assumed focus upon short-term results (e.g.. Miller & Le-Breton Miller, 2005)? Do transnational differences in capital markets affect longevity? Do intemational differences in the importance of the social dimension of economic transactions play any role in organizational performance and survival?

C. Bring on Death?

If we conceive of organizations as utility maximizing humans, then, yes, they ought to live forever. But if we adopt a different analogy, namely, that organizations are tools, similar to machines, as suggested by Weber (1964), then organizations ought to last only until their functional utility is exhausted. 

In fact, this is precisely how business corporations were originally conceived. They were designed as limited purpose entities and, until relatively recently, most corporate charters were granted not only for a limited time period, but also for narrowly specified purposes. From this point of view, it is hardly surprising that business organizations do not ‘outlive’ individuals. If business organizations are conceived with the underlying metaphor of a tool used by investors to maximize shareholder wealth, then longevity might be considered an undesirable outcome.

So, why is the eternal life of an organization considered to be an attractive goal today, Put another way, who benefits from creating the illusion that organizations are sentient organisms with the capacity to choose their life span and their scope of action?

<- It is the managerial class, the MBAs and CEOs that now populate business organizations that benefit most from changing the underlying metaphor of business organizations away from the idea that they are tools and toward the perception that they are ‘corporate persons’ without constraints on life or purpose.


Death is not a success: reflections on business exit

This paper is a critical evaluation of claims that business exits should not be seen as failures, on the grounds that sometimes they correspond to voluntary liquidations, or because they are /successful learning opportunities. We reiterate that the vast majority of business exits are unsuccessful. Drawing on ideas from the organizational life course, we suggest that “death” is a better word than “failure” to describe the phenomenon of business exit – we underline that it is not helpful to consider business exits as successful events.

Business exit always relates to unviable businesses – whether they be ‘relatively unviable’ when taking into account the entrepreneur’s outside options, or ‘absolutely unviable’ in the economic sense of being unable to cover its costs. Viable businesses that remain in operation even after the entrepreneur leaves (e.g. trade sale or initial public offering (IPO)) are not, in fact, cases of business death, but cases of business continuation.


In some cases, such as an IPO or an acquisition involving the sale of the start-up, entrepreneurial exit can be considered to be a success. Brander et al (2010, p4) write that “using exits as a measure of success is standard in the venture capital literature.” 

<- This kind of successful entrepreneurial exit, according to which the business continues operations after the exit of the entrepreneur but under new management or with new investors, should be conceptualized as a case of business survival, not business exit.

-> We would agree that this type of exit should be seen as a success. However, given that our paper is not concerned with entrepreneurial exit, or investor exit, but our unit of observation is the business, we can sidestep this category of events. We therefore distance ourselves from the standard approach in the survival literature that considers merger and acquisition (M&A) to be a form of exit (e.g. Schary 1991; Cefis and Marsili 2006; Bhattacharjee et al 2009; Balcaen et al 2011). 

(Although reincorporation and change of legal form may constitute a death and re-birth in the way these events are recorded in some national statistics databases, this is not a meaningful death/rebirth in an economic sense (Harada 2007 p403; Hoetker and Agarwal 2007 p447), and statistical offices recognise this and are working on ways of no longer coding a change of legal form as a death and subsequent rebirth. )

We argue here that voluntary closure can be characterized as ‘relatively unviable’: the case where the business has failed to be a viable economic entity when the entrepreneur considers her other outside options, even if it generates enough revenue to cover its costs./The business has perhaps played a useful role in the past, but now the opportunity cost of the business remaining in operation is too high to allow it to continue.

We define ‘absolutely unviable’ with involuntary closureas the case when a business fails to cover its costs even when we leave aside issues of the entrepreneur’s opportunity cost. 

While involuntary business closure corresponds to bankruptcy, voluntary business closure refers to liquidation, which can be described as either a ‘harvest’ liquidation or a ‘distress’ liquidation (Wennberg et al, 2010).

-> Of these two latter outcomes, harvest liquidation is considered to be more successful than distress liquidation. Harvest liquidation corresponds to the liquidation of a successful business, for motivations such as retirement, or perhaps the natural winding-down of projects that had always been thought of as short-term projects.

–>> In our view, the distinction between voluntary and involuntary closure is not always very helpful. 1) self-reported evaluations undertaken by unsuccessful entrepreneurs are likely to be strongly affected by cognitive biases . 2) many business exits that are classified as voluntary closures would have been classified as involuntary closures had the business closure taken place shortly afterwards. 

Technology Spreading


The impact of public mechanical clocks on economic growth

Are Smart Phones Spreading Faster than Any Technology in Human History?


In a past post about short-termism, we introduced a picture that shows the shortening diffusion time of new technologies from telephone to internet access, which means the period of competitive advantage is shrinking for companies.

Today we go through two articles about the topic of technology spreading.


1.The public mechanical clock in 13th century

Lars Boerner, one of my lecturer in the EH department of LSE, wrote a paper about the impact of public mechanical clocks on mid-century Europe’s economic growth.

European cities that were quick to install mechanical clocks enjoyed greater growth than late adopters. However, it takes some time for the effects from fundamental innovations of this type to be realised because the technology must be accepted both culturally and socially and then applied to related economic activities.

We focus on the later part.

Starting in the late 13th century, clocks started spreading simultaneously across Italy, Germany, and England, and then spread until 1450 in most other Western and Central European Countries, including Belgium, the Netherlands, France, Spain, Poland, the current Czech Republic, and Scandinavia

The diffusion curve of the mechanical clocksevergninifig2

The spread followed the s-shaped distribution curve that is typical for new technologies. The distribution weighted by the total population size started slowly, then rose exponentially, and finally slowed down again, reaching a saturation point in 1450 with a relative decreasing adoption rate.

-> The economic use of clocks was a slow process of adoption.

<- Building a clock in a town was motivated by prestige and not by economic needs – towns did not forecast ex post benefits as an economically efficient application.
<- The use of clocks for coordination activities, such as market times or administrative town meetings, can already be observed during the 14th and 15th centuries, the use of clocks to monitor and coordinate labour processes evolved only slowly, in particular during the 16th century.
<- Finally, a cultural adoption reflected in the daily cultural and philosophical thinking of the time can be observed from the middle of the 16th century

The conclusion here is that for the implement of new technologies, it is indeed important to let societies learn to use them and adapt to them to reap the full benefits.


2.Smart phones spreads faster than any technology in human history

Today, we have the fastest ever diffusion speed in the human history: software apps are reaching tens of millions of users within weeks.

<- Underlying these developments: the unprecedented speed at which mobile computers are spreading.

Presented below is the U.S. market penetration achieved by nine technologies since 1876. Penetration rates have been organized to show three phases of a technology’s spread: traction, maturity, and saturation.


It took almost a century for landline phones to reach saturation, or the point at which new demand falls off. Mobile phones, by contrast, achieved saturation in just 20 years. Smart phones are on track to halve that rate yet again, and tablets could move still faster. 

-> Those technologies with “last mile” problems—bringing electricity cables or telephone wire to individual homes—appear to spread more slowly.

Smart phones have gone from 5 percent to 40 percent in about four years, despite a recession. [1]




In late 2006, the quarter before Apple announced its now-iconic iPhone, only 715,000 smart phones were sold, representing just 6 percent of U.S. mobile-phone sales by volume. Up to that point, the smart phone was spreading not much faster than personal computers had in the preceding decades, and more slowly than radio decades before.

That changed when Apple’s iPhone sold 1.12 million units in its first full quarter of availability, despite prices starting at $399. Year over year, the market share of smart phones almost doubled, to 11 percent of U.S. mobile-phone sales. Now Nielsen reports that smart phones represent more than two-thirds of all U.S. mobile-phone sales.


Lifespans of Firms


Creative Destruction Whips through Corporate America

Die Another Day: What Leaders Can Do About the Shrinking Life Expectancy of Corporations

BCG Classics Revisited: The Growth Share Matrix

Where Do Firms Go When They Die?

This Is a Fine Time to Be a Big Corporation

Can a company live forever?



Lifespans of Top companies are shrinking

Richard N. Foster, first in his book Creative Destruction with Sarah Kaplan in 2001, and then in a report in 2012 argues that “lifespans of top companies are shrinking” according to the study on S&P 500 index rotation.


“61-year tenure for average firm in 1958 narrowed to 25 years in 1980, and to 18 years in 2012, based on a seven year rolling averages.”

“If removal from the S&P 500 is not due to an acquisition [3], it can be a jolt that emphasizes the urgency of turnaround effort or it can be a prelude to delisting and the threat of bankruptcy.”

->” To survive and and thrive,  leaders must “create, operate, and trade” – build new divisions and trade mature ones at the pace and scale of the market without losing control their company. “

“‘creative destruction’, widely credited to Joseph Schumpeter, indicates that economic progress, in capitalist society, means turmoil”

-> “According to Foster, the life span of a corporation is determined by balancing three management imperatives:
1) running operations effectively,
2) creating new businesses which meet customer needs [1]
3) shedding business that once might have been core but now no longer meet company standards for growth and return.” 

<- The problem is that the innovation that is needed to create significant new businesses can often directly conflict with the operational effectiveness of the current business. Under these circumstances large companies slowly fall behind the pace of change of the economy.  [2]


A changing Business Environment 

In 2014, BCG revised its famous BCG’s growth-share matrix [4], as the world has changed:

since 1970, when it was introduced, conglomerates have become less prevalent, change has accelerated, and competitive advantage has become less durable. The business environment has become more dynamic and unpredictable, and market share has become less of a driver of and surrogate for advantage.

1. companies face circumstances that change more rapidly and unpredictably than ever before because of technological advances and other factors.

-> proportionately lower numbers of cash cows because their longevity is likely in many cases to be curtailed.

<- companies need to constantly renew their advantage through disciplined experimentation (to invest in more question marks, experiment with them in a quicker and more economical way than competitors, and systematically select promising ones to grow into stars), increasing the speed at which they shift resources among products and business units share is no longer a direct predictor of sustained performance.

<- new drivers of competitive advantage, such as the ability to adapt to changing circumstances or to shape them



Shrinking Life Expectancy of Corporations

“we are in an era of unprecedented technological disruption and change that only the most forward-looking companies will survive.”

To understand how the battle for long-term survival has changed and the implications for both challengers and incumbents, BCG analyzed patterns of entry, growth, and exit for 35,000 companies publicly listed in the US since 1950-2013 —with surprising results.

1.  corporate survival and death

BCG focused on companies exiting the public-company pool —whether owing to bankruptcy or liquidation, merger or acquisition, or other causes (exit years correspond either to the database (compustat) deletion date or to the last recorded instance of income or revenues.), and found is that public companies are perishing sooner than ever before


Since 1950, the total life span of companies (calculated as the period between founding year and exit year (irrespective of gaps in sales reporting)) and the length of time that their shares are publicly traded have significantly decreased.In fact, businesses are dying at a much younger age than the people who run them.

2.Rising Mortality Risk

Today, almost one-tenth of all public companies fail each year, a fourfold increase since 1965.

スクリーンショット 2016-10-21 15.28.47.png

The five-year exit risk for public companies traded in the US now stands at 32 percent, compared with the 5 percent risk they would have faced 50 years ago.

One might expect particular types of company, such as new entrants in the technology sector, to account for most of the observed shift. Surprisingly, however, our research shows that the surge in mortality risk is widespread: 

There are no safe harbors. Mortality risk grew relatively uniformly across all sectors of the economy.  [6]

Neither scale nor experience is a safeguard. Mortality risk also grew for companies of all sizes and ages. [7]

3. Why it happens

In the economic and venture-capital-funding booms of the mid-1980s and mid- to late-’90s, many smaller and younger companies entered the public markets.

-> These companies (less than 10 years old and had less than $50 million in sales) had a more than 25 percent higher risk of failure compared with the average company—likely owing to poorer quality (a lower bar for entry), few buffers against failure (lack of resources), and intense peer pressure (the smallest companies faced the highest competitive density).

–>> Those that endured grew into serious competitors for incumbents, driving up the death rate among medium-size and large established companies, which were often unable to react quickly enough to the disruptions wrought by these smaller upstarts.

—>>> Surviving incumbents then began to react by acquiring small-to-medium-size companies, again driving up exit rates in this segment while stabilizing turnover among large companies. [8]

4. A Growth-Endurance Trade-Off

BCG observed a surprising relationship between revenue growth and mortality:  accelerated growth correlates with shorter life spans, whereas companies with more moderate growth face the lowest risk. (This correlation holds true across the entire period of analysis and remains significant even when controlling for factors such as age, size, industry, and profitability.)


+ Over the period of our analysis, the average cumulative profits of public companies declined at an even sharper rate than corporate life spans.

-> rather than achieving their full potential in less time, the contraction of corporate life spans, on average, diminishes long-term value creation. Longer-lived companies thus appear to create more value than fast-growing, short-lived ones.


Publicly-traded firms die off at the same rate regardless of their age or economic sector

Log sales of some 30,000 U.S. Companies 1950-2009
(controlling for inflation and GDP growth)


This picture credited by Marcus Hamilton and Madeleine Daepp partly proves some assumptions BCG made above.

<- The relatively rapid growth of smaller companies near the beginnings of their lifespans account for the ragged lower portion of the chart, as well as the relatively steep initial sales increases. As companies reach maturity, their sales tend to level off.

Looking at a database of 25,000 companies from 1950 to 2009, they found that publicly traded companies die off at the same rate, regardless of the firm’s age or what sector it’s in. In their dataset, they found that most firms live about 10 years and the most common reason a company disappears is due to a merger or acquisition.

(However, the problem here is that they are only doing with listed time. Firms may take long time until going listed, and different industry may vary significantly. And can we simply recognize companies merged equally as being demised or perished?)


Fortune 500 story

Researchers Dane Stangler and Sam Arbesman have some different ideas by examining annual turnover in the Fortune 500 list, the first of which was compiled in 1955.


The number of companies leaving (and entering) the Fortune 500, which ranks the largest corporations by revenue, rose through the 1980s and 1990s, but is down since.


-> Stangler and Arbesman cite several historical studies that seem to show that this stuff comes in waves. The 1920s was a decade of high turnover in the ranks of the country’s 100 largest corporations; the 1940s saw very low turnover. Then again, turnover in a list of the top 500 or 100 companies isn’t the same as the average corporate life expectancy. It could be that the long-run trend there is in fact downward.

-> Big companies have been doing a better job of sticking around and thriving since 2000. Meanwhile, broader “business dynamism” research based mostly on U.S. Census data shows that, on the whole, bigger, older companies control more of economic activity than they did not just 15 years ago but also 40 years ago.

Can a company live forever?

It is perhaps unsurprising that the country where people live the longest is also home to some of the oldest companies in the world.

<- In Japan, there are more than 20,000 companies that are more than 100 years old, with a handful that are more than 1,000 years old, according to credit rating agency Tokyo Shoko Research.

->  1. Professor Makoto Kanda, who has studied shinise for decades, says that Japanese companies can survive for so long because they are small, mostly family-run, and because they focus on a central belief or credo that is not tied solely to making a profit.

-> 2. Local factors could be another key to their success. Shinise focus primarily on the Japanese market, from Kikkoman’s products to small sake manufacturers, and they benefit from a corporate culture that has long avoided the mergers and acquisitions that are common among their Western counterparts.

Although there are exceptions to every rule, the most important factor for survival is an emphasis on innovation and reinvention.

-> However, innovation for the sake of it is not the goal, It is a focus on “little bets” that helps companies grow and keep up with the competition.

–>> Innovation in general is not always easy, however, especially for publicly listed companies that must balance the concerns of capital markets and shareholders, who demand quarterly profits and who are not necessarily interested in decades-long research projects.

Yet even if a company can innovate and conditions do remain favourable, immortality does have its downsides.

For instance, there is no real proof that age makes a company any more profitable than younger companies. On the contrary, evidence from the stock market actually suggests that age could be a hindrance.

Of the 74 or so companies that have stayed in the S&P 500 for more than 40 years, only a dozen or so have managed to beat the average, according to a study by consultancy McKinsey.




“companies that have embraced the “create, operate, and trade without losing control” strategy include IBM, GE and Johnson & Johnson. Each of these companies create, often by buying smaller companies in the market that are poorly positioned to expand their products internationally. They also free up capital by divesting business units at the same time–all while maintaining control of their margins and returns.”


“How fast do we have to change to maintain our position within our industry?” The pace of change varies by industry. That said, if one’s industry is changing more slowly than the pace of change in the economy, that industry itself will experience gradual “fade’ and often replacement by lower cost international competitors. Doubters only have to think about the steel, auto or paper businesses to find examples.


“mergers and acquisitions tend to increase when the economy is growing, leading to higher returns on equity.

When the market for deals and IPOs is depressed, as it has been for several years, demand for creative destruction builds up. This pent-up entrepreneurial energy and demand for deals typically gets unleashed when the economy is stronger.”


“The matrix helped companies decide which markets and business units to invest in on the basis of two factors—company competitiveness and market attractiveness—with the underlying drivers for these factors being relative market share and growth rate, respectively. The logic was that market leadership, expressed through high relative share, resulted in sustainably superior returns. In the long run, the market leader obtained a self-reinforcing cost advantage through scale and experience that competitors found difficult to replicate. High growth rates signaled the markets in which leadership could be most easily built.

Putting these drivers in a matrix revealed four quadrants, each with a specific strategic imperative. Low-growth, high-share “cash cows” should be milked for cash to reinvest in high-growth, high-share “stars” with high future potential. High-growth, low-share “question marks” should be invested in or discarded, depending on their chances of becoming stars. Low-share, low-growth “pets” are essentially worthless and should be liquidated, divested, or repositioned given that their current positioning is unlikely to ever generate cash.”


BCG used Compustat’s database (1950 to 2013) for our core data set and then matched companies with the S&P Capital IQ database to obtain additional data points. The data set includes foreign companies listed on US exchanges. 


Only the past decade saw a slight divergence in outcomes: traditionally stable oligopolies (such as the oil and gas industry) recovered the most, while mortality remains high in more dynamic industries (such as technology).


While smaller companies have always faced greater risk, even the largest companies are now facing higher exit rates. Company age only began to affect exit risk in the first decade of the 2000s, when turnover plateaued for older companies but continued to grow among younger ones.


Take the example of Compaq Computer. Founded in 1982, it went public and shot to success extremely fast. Unlike many of its peers (Altos Computer Systems, Corona Data Systems, Eagle Computer, and Osborne Computer), Compaq survived into the ‘90s, establishing itself as a serious threat to incumbents in the computer industry. Among the much older and larger incumbents it disrupted was DEC, which was sold to Compaq in 1998. Another giant, HP, saved itself from the same fate by buying up Compaq after the company struggled through the dot-com collapse. 



Yield and Credit


Hunt for Yield and Wild Goose Chases

Triple A, 30-Years? Mate, That’s a Bargain

Sinking Yuan Risks Dragging Down Banks

Silicon Valley’s Cool Kids Are Turning Into Squares


A rotation on investors’ flavour 

The demand for High dividend yield changes since the yield left the bottom.




The rotation might be another overreaction, but valuations for dividend stocks are still lofty.


Anyway, the looking-for-yield game seems not going to end

Australia’s government sold its biggest-ever bond, raising A$7.6 billion ($5.8 billion) in its first ever offering of 30-year notes (triple-A rating). The 3.27 percent yield is less than what the country paid for securities due in five years as recently as 2014, and buyers from abroad snapped up almost two-thirds of the issue.

<- That yield and credit score combination make the 30-year notes particularly attractive to global financial institutions, which have started to adopt new liquidity coverage ratios required by banking rules introduced after the 2008 crisis. [1]


Banks, however, are in the business of making money, not holding bonds for an unlikely run on deposits. So treasurers go through pains to try and squeeze some yield out of holding all those godforsaken securities. That’s become increasingly difficult since the European Central Bank and the Bank of Japan (in spite of its nation’s single-A credit grade) embraced negative interest rates.


Another negative-rate environment trait is that the average maturity of debt lengthens. There’s a body of academic work that has found a correlation between lower yields and longer government debt maturities.



While banks in China is suffering from a weaker yuan

Investors have good reason to worry as debt continues to explode and money keeps flowing out of the country. Goldman Sachs says a rising amount of capital is leaving China in yuan rather than dollars and the moves can’t be explained by market-driven factors.


While less expects stimulation on export, outflows in turn will further weigh on the yuan in a vicious cycle that could have serious effects on China Inc., especially given that the country’s corporations have taken on record amounts of foreign currency debt.


This year alone, dollar- and euro-denominated loans taken out by Chinese companies have reached $195 billion, bringing the total outstanding to about $650 billion. That’s equivalent to the total amount of subprime mortgage loans outstanding in the U.S. in 2008.

-> S&P Global Ratings said that if China’s corporate debt doesn’t stop growing, it could cost banks $1.7 trillion (the amount of extra capital they would have to raise.)

(That’s why the state just issued guidelines for how banks may swap bad debt to equity. One may argue lenders will not be happy to hold hundreds companies in sectors with little prospect of turnaround, such as steel or coal mining. But at least according to Oliver Hart, it can be an efficient way to solve debt issues.)


Start-ups also feel cold on less capital inflow

Capital going into start-ups globally has fallen for the last four quarters to reach $24.1 billion in the third quarter, a level not seen since two years ago, according to a KPMG and CB Insights report. The trend holds for early and late-stage funding rounds.


A big reason for this is that valuations are cooling for many private start-ups from the biggest such as Airbnb to smaller ones like Rocket Internet-backed Global Fashion Group.

<- Funds are loath to contribute more money to a start-up in a later round at a lower valuation since it looks bad for their own performance. So they’re pushing their companies to pay more attention to profit and cost, rather than just handing them more cash to let them pursue breakneck sales and user growth.Uber’s tactical retreat from a war of attrition in China is but one example.

However, VCs have secured promises worth billions from limited partners, such as endowments and foundations, who expect them to put money to work. [2]

-> “VCs may need to get out their comfort zones to invest in a broader palette of sectors.”




Those Basel III guidelines mean that banks need to hold enough liquid securities to withstand 30 days of the kind of liquidity crunch that was seen back then. The devil in the detail here is what constitutes liquid. And outside of good hard cash, triple-A government securities get one of the best regulatory treatments.


The life of a typical fund is between eight and 12 years, and investments are made gradually in the first half of that period.
