This paper examines the long-run dynamics and the cyclical structure of the US stock market using fractional integration techniques. We implement a version of the tests of Robinson (1994a), which enables one to consider unit (or fractional) roots both at the zero (long-run) and at the cyclical...

Promising emerging equity markets often witness investment herds and frenzies, accompanied by an abundance of media coverage. Complementarity in information acquisition can explain these anomalies. Because information has a high fixed cost of production, its equilibrium price is low when...

Most investors purchase securities knowing they will resell those securities in the future. Uncertainty about the preferences of future trading counter-parties causes randomness in future resale prices that we call liquidity risk. It is natural to suppose that investors are asymmetrically...

``Limits of Arbitrage" theories require that the marginal investor in a particular asset market be a specialized arbitrageur. Then the constraints faced by this arbitrageur (i.e. capital constraints) feed through into asset prices. We examine the mortgage-backed securities (MBS) market in this...

We study how heterogeneous beliefs affect returns and examine whether heterogeneous beliefs are a priced factor in traditional asset pricing models. To accomplish this task, we suggest new empirical measures based on the disagreement among analysts about expected (short-term and long-term)...

We examine the impact of R&D intensity and agency costs on the value of firms across 13 economies. We find that R&D adds value while high agency costs reduce value. R&D adds value, however, even when agency costs are high. We show that in those firms where agency costs are high and R&D intensity...

Unexpected variation in emissions can have an enormous impact on the prices of emission permits and the efficiency achieved in tradable permit markets. Shocks to emission levels can be correlated across firms; for example, most firms require more emission permits than planned for following a...

This paper presents a participation game experiment to study the impact of uncertainty and costly political participation on the incidence of reform. Fernandez and Rodrik (1991) show that uncertainty about who will ultimately gain or lose as a result of a reform can prevent its adoption. We...

In many markets consumer biases do not affect prices, since competition forces firms to price their products close to marginal cost; competition protects the consumer. We show that noisy consumer product evaluations undermine the force of competition, enabling firms to charge high mark-ups in...

This work introduces a rigorous set-theoretic foundation of bilateral matching mechanisms and studies their properties in a systematic manner. By providing a unified framework to study ilateral matching mechanisms, we formalize how different spatial/informational constraints can be implemented...
