A service provider sells to homogenous risk-averse consumers through a two-part tariff. The consumers have uncertain tastes toward the service. They subscribe the service before the uncertainty resolves. In contrast with the common view that a monpolist's optimal two-part tariff for homogeneous...

In a recent paper, Hart and Moore (2008) introduce new behavioral assumptions that can explain long term contracts and important aspects of the employment relation. However, so far there exists no direct evidence that supports these assumptions and, in particular, Hart and Moore's notion that...

This chapter studies how incomplete information helps accommodate frictions in coordination, leading to novel insights on the joint determination of expectations and macroeconomic outcomes. We review and synthesize recent work on global games, beauty contests, and their applications. We...

We provide experimental evidence that panic bank runs occur in the absence of problems with fundamentals and coordination failures among depositors, the two main culprits identified in the literature. Depositors withdraw when they observe that others do so, even when theoretically they should...
