How long do firms live? Research finds patterns of company mortality in market data

Companies come and go for a variety of reasons. Some are bought, some merge with others, and some go out of business completely. There's no shortage of theories about why.

“The theory of the firm–there are whole books on what people think is going on,” says Marcus Hamilton, an SFI postdoctoral fellow and corresponding author of a new paper published in the journal Royal Society Interface.

Despite that, he says, “there is remarkably little quantitative work” on what economists call company mortality, and existing theory and evidence yield contradictory answers. Some researchers think younger companies are more likely to die than older ones, while others think just the opposite.

“We wanted to see if there was any kind of standard behavior or if it was just random,” Hamilton says.

Hamilton, SFI Distinguished Professor Geoffrey West, and SFI Professor Luis Bettencourt asked Madeleine Daepp, then an Edward A. Knapp Undergraduate Fellow at SFI and first author of the new paper, to take the lead. “We gave her this basic idea, and she did the heavy lifting,” Hamilton says. Daepp is now a graduate student at the University of British Columbia.

The heavy lifting, Hamilton explains, was going through Standard and Poor's Compustat, an expansive database of information on publicly-traded companies dating back to 1950. Using a statistical technique called survival analysis, Daepp and her mentors discovered something no one had predicted: a firm's mortality rate — its risk of dying in, say, the next year — had nothing to do with how long it had already been in business or what kinds of products it produced.

“It doesn't matter if you're selling bananas, airplanes, or whatever,” Hamilton says — the mortality rate is the same. Though the number, of course, varies from firm to firm, the team estimated that the typical company lasts about ten years before it's bought out, merges, or gets liquidated.

“The next question is, why might that be?” Hamilton says. The new paper largely avoids engaging with any particular economic model, though the researchers have some hypotheses inspired by ecological systems, where plants and animals have their own internal dynamics but must also compete for scarce resources — just like businesses do.
