We distinguish between three sets of rights - property rights, political rights, and civil rights - and provide a taxonomy of political regimes. The distinctive nature of liberal democracy is that it protects civil rights (equality before the law for minorities) in addition to the other two....

This paper addresses a key question on the design of electoral systems. Should all voters vote on the same day or should elections be staggered, with late voters observing early returns before making their decisions? Using a model of voting and social learning, we illustrate that sequential...

This paper reformulates the New Keynesian model to incorporate output adjustments through the extensive margin. Shifting from adjustments through the intensive to the extensive employment margin, the model introduces predetermined output, altering key properties of the New Keynesian framework....

In a market with symmetric information about fundamentals, can information-based trade still arise? Consider bond and FX markets, where private information about nominal cash flows is generally absent, but participants are convinced that superior information exists. We analyze a class of...

Empirical evidence shows that macroeconomic fundamentals have little explanatory power for nominal exchange rates. On the other hand, the recent microstructure approach to exchange rates' has shown that most exchange rate volatility at short to medium horizons is related to order flows. This...

We propose a new approach to modeling the cost of information structures in rational inattention problems, the "neighborhood-based" cost functions. These cost functions have two properties that we view as desirable: they summarize the results of a sequential evidence accumulation problem, and...

This paper investigates the role played by informational frictions in college and the workplace. We estimate a dynamic structural model of schooling and work decisions, where individuals have imperfect information about their schooling ability and labor market productivity. We take into account...

Popularity is self reinforcing. The attention garnered by popular options propels further interest in them. Yet rather than blindly follow the crowd, most pay attention to how well these items match their tastes. We model this role of social learning in guiding selective attention and market...

Technological progress is typically a result of trial-and-error research by competing firms. While some research paths lead to the innovation sought, others result in dead ends. Because firms benefit from their competitors working in the wrong direction, they do not reveal their dead-end...
