We study how transparency, modeled as information about one's counterparty liquidity needs, affects the functioning of an over-the-counter market. In our model, investors hedge endowment risk by trading bilaterally in a search-and-matching environment. We construct a bargaining procedure that...

We provide a novel explanation for the empirical failure of the CAPM despite its widespread practical use. In a rational-expectations economy in which information is dispersed, variation in expected returns over time and across investors creates an informational gap between investors and the...

Investment is a means to experiment with technologies, creating valuable knowledge for firms. We analyze the feedback interaction between investment and knowledge through endogenous cycles of experimentation and exploration. Because experimentation is uncertain, firms become averse to investing...

Asset-pricing facts on FOMC announcements have changed strikingly in the last decade. The pre-announcement drift has disappeared, and other known facts - the announcement premium and a stronger CAPM - now concentrate on a subset of announcements. We propose these distinct patterns correspond to...

We propose a joint theory of time-series momentum and reversal based on a rational-expectations model. We show that a necessary condition for momentum to arise in this framework is that information flows at an increasing rate. We focus on word-of-mouth communication as a mechanism that enforces...
