This paper reconsiders the Phelps-Lucas hypothesis, according to which temporary real effects of purely nominal disturbances result from imperfect information, but departs from the assumptions of Lucas (1973) in two crucial respects. Due to monopolistically competitive pricing, higher-order...

During recent episodes of financial turmoil some policy makers voiced concerns about aggressive, and possibly manipulative, practices by highly leveraged institutions in emerging markets. This paper addresses these concerns by reconsidering in detail, at both theoretical and empirical levels,...

We develop an international financial market model in which domestic and foreign residents differ in their beliefs about the information content in public signals. We determine how informational advantages by domestic investors in the interpretation of home public signals impact equity markets....

A positive correlation between insurance coverage and ex post risk can be an indicator for private information in insurance markets. However, this test fails if agents have heterogeneous risk attitudes. We propose a new test that conditions on unobserved types of individuals who differ in their...

This paper develops a model to analyze information aggregation in commodity markets. Through centralized trading, commodity prices aggregate dispersed information about the strength of the global economy among goods producers whose production has complementarity, and serve as price signals to...

The paper develops a model of foreign direct investments (FDI) and foreign portfolio investments (FPI).The model describes an information-based trade off between direct investments and portfolio investments. Direct investors are more informed about the fundamentals of their projects. This...

We propose a tractable model of an informationally inefficient market featuring non-revealing prices, no noise traders, and general assumptions on preferences and payoff distributions. We show the equivalence between our model and a substantially simpler model whereby investors face...

When governments choose trade policy, rarely do they have complete information, At the time decisions are made, policy makers have only estimates of market responses, as well as the responses of foreign governments. In many realistic situations, even the policy objectives of other governments...

We study the Rothschild-Stiglitz model of insurance markets, introducing endogenous information disclosure about insurance sales and purchases by firms and consumers. We show that a competitive equilibrium exists under unusually mild conditions, and characterize the unique equilibrium outcome....

The social and the private returns to education differ when education can increase productivity, and also be used to signal productivity. We show how instrumental variables can be used to separately identify and estimate the social and private returns to education within the employer learning...
