This paper shows that active investors, such as venture capitalists, can affect the speed at which new ventures grow. In the absence of product market competition, new ventures financed by active investors grow faster initially, though in the long run those financed by passive investors are able to catch up. By contrast, in a competitive product market, new ventures financed by active investors...

Investors’ previous experiences with a stock affect their willingness to repurchase that stock. Using detailed trade data from two brokers, the authors document that investors are reluctant to repurchase stocks previously sold for a loss and stocks that have risen in price subsequent to a prior sale. The authors propose that this behavior reflects investors’ emotional reactions to trading and t...

When I studied microeconomics forty years ago, I was first taught how optimizing firms and consumers would behave, and then taught the nature of the economic equilibrium which would result from such behavior. Let me refer to this as part one and part two of my microeconomics course. My work on portfolio theory considers how an optimizing investor would behave, whereas the work by Sharpe and Lin...

This paper incorporates an annual probability of corporate failure into a standard equity valuation model, as an alternative or complementary correction for risk that improves in several ways over conventional risk premia or ad hoc adjustments to assumed growth rates. Though the correction is nonlinear, it can be reduced to an equivalent function that enters the valuation equation in the tradit...

Traditionally, models of resource extraction assume individuals act as if they form strategies based on complete information. In reality, gathering information about environmental parameters may be costly. An efficient information gathering strategy is to observe the foraging behavior of others, termed public information. However, media can exploit this strategy by appearing to supply accurate ...

This study examines the joint effect of disclosed measurement information and investor mindset on investors' judgments of estimate precision and firm value. Consistent with psychology theory, results reveal that short horizon investors adopt a relatively concrete mindset and long horizon investors adopt a relatively abstract mindset. As a consequence, disclosing that the fair value of an impair...

This study investigates whether Asian investors trade overconfidently and what factors affect their overconfident trading based on the theoretical predictions of Gervais and Odean (2001) that market gains make investors trade overconfidently in subsequent periods. We find that Asian investors trade more aggressively subsequent to both domestic and U.S. market gains and their overconfident tradi...

We consider a multi-period rational expectations model in which risk-averse investors differ in their information on past transaction prices (the ticker). Some investors (insiders) observe prices in real-time whereas other investors (outsiders) observe prices with a delay. As prices are informative about the asset payoff, insiders get a strictly larger expected utility than outsiders. Yet, info...
