Two means by which commodity producers can reduce their exposure to quantity risk are share contracting and futures hedging. This paper explains the coexistence of these arrangements by showing that these will normally be complementary means of transferring risk. Share contracting by a purchaser...

We examine how investor preferences and beliefs affect trading in relation to past gains and losses. The probability of selling as a function of profit is V-shaped; at short holding periods, investors are more likely to sell big losers than small ones. There is little evidence of an upward jump in...

Behavioral theories suggest that investor misperceptions and market mispricing will be correlated across firms. We use equity and debt financing to identify common misvaluation across firms. A zero-investment portfolio (UMO, Undervalued Minus Overvalued) built from repurchase and new issue firms...

This paper examines equilibrium in a spot and futures market with both primary producers (growers) and intermediate producers (processo rs). For a commodity that is subject to output shocks, processors tend to hedge long, in contrast with J. R. Hicks's theory of futures hedging. Nevertheless, if...

An information cascade occurs when it is optimal for an individual, having observed the actions and possibly payoffs of those ahead of him, to take the same action regardless of his own information. When there are informational cascades, society may reap only a modest fraction of the potential...

We provide a model in which irrational investors trade based upon considerations that have no inherent connection to fundamentals. However, trading activity affects market prices, and because of feedback from security prices to cash flows, the irrational trades influence underlying cash flows....

We analyze capital allocation in a conglomerate where divisional managers with uncertain abilities compete for promotion to CEO. A manager can sometimes gain by unobservably adding variance to divisional output. Capital rationing can limit this distortion, increase productive efficiency, and...

This paper offers an explanation for the forward discount puzzle in foreign exchange markets based upon investor overconfidence. In contrast with behavioral biases conjectured specifically to explain the puzzle, overconfidence is a well-documented psychological phenomenon that has been found to...

Evidence indicates that people fear change and the unknown. We offer a model of familiarity bias in which individuals focus on adverse scenarios in evaluating defections from the status quo. The model explains the endowment effect, portfolio underdiversification, home and local biases....

This paper examines how imperfect institutional memory affects organizational decisions. In our model, a manager knows his firm's previous actions but (owing, e.g., to turnover) not the rationale for these actions. If the environment is stable, we find that a firm that has followed an old policy...
