We develop a search-based model of asset trading, in which investors of different horizons can invest in two identical assets. The asset markets are partially segmented: buyers can search for only one asset, but can decide which one. We show that there exists a "clientele" equilibrium where one...

We propose a model of organizational decision making, in which information processing is decentralized. Our model incorporates two features of many actual organizations: aggregation entails a loss of useful information, and the decision problems of different agents interact. We assume that an...

We study market efficiency in an infinite-horizon model with a monopolistic insider. The insider can trade with a competitive market maker and noise traders, and observes privately the expected growth rate of asset dividends. In the absence of the insider, this information would be reflected in...

We propose a dynamic equilibrium model of a multi-asset market with stochastic volatility and transaction costs. Our key assumption is that investors are fund managers, subject to withdrawals when fund performance falls below a threshold. This generates a preference for liquidity that is...

In this article we study the effects of transaction costs on asset prices. We assume an overlapping generations economy with a riskless, liquid bond, and many risky stocks carrying proportional transaction costs. We obtain stock prices and turnover in closed form. Surprisingly, a stock's price...

We develop a model of the gambler's fallacy (the mistaken belief that random sequences should exhibit systematic reversals). We show that an individual who holds this belief and observes a sequence of signals can exaggerate the magnitude of changes in an underlying state but underestimate their...

In this paper we study the effects of transaction costs on asset prices. We assume an overlapping generations economy with two riskless assets. The first asset is liquid while the second asset carries proportional transaction costs. We show that agents buy the liquid asset for short-term...
