We propose a multi-period model in which competitive arbitrageurs exploit discrepancies between the prices of two identical risky assets, traded in segmented markets. Arbitrageurs need to collateralize separately their positions in each asset, and this implies a financial constraint limiting...

We examine empirically how the maturity structure of government debt affects bond yields and excess returns. We organize our investigation around a model of preferred habitat, in which supply shocks impact an arbitrage-free term structure. Consistent with the model, we find that the relative...

We propose a rational theory of momentum and reversal based on delegated portfolio management. An investor can hold assets through an index or an active fund. Investing in the active fund involves a time-varying cost, interpreted as managerial perk or ability. The investor responds to an...

We model the term structure of interest rates as resulting from the interaction between investor clienteles with preferences for specific maturities and risk-averse arbitrageurs. Because arbitrageurs are risk averse, shocks to clienteles' demand for bonds affect the term structure --- and...

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...

We propose a model in which assets with identical cash flows can trade at different prices. Infinitely-lived agents can establish long positions in a search spot market, or short positions by first borrowing an asset in a search repo market. We show that short-sellers can endogenously...

We propose a model in which assets with identical cash flows can trade at different prices. Agents enter into an infinite-horizon, steady-state market to establish long or short positions. Both the spot and the asset-lending market operate through search. Short-sellers can endogenously...

In this article 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...

We propose a boundedly-rational model of opinion formation where agents are subject to the phenomenon of persuasion. We argue that persuasion - whereby repeated exposure to an opinion has a cumulative effect on an agent's beliefs - is pervasive and closely related to the concept of social...
