International surveys reveal wide differences between the views held in different countries concerning the causes of wealth or poverty and the extent to which people are responsible for their own fate. At the same time, social ethnographies and experiments by psychologists demonstrate...

This Paper shows that over monitoring a partner in the initial phase of a relationship may not be optimal if the goal is to determine loyalty and if the cost of ending the relationship increases over time. This intuition is simple: by monitoring too much we lose the opportunity to learn how the...

I study the constrained efficient allocations of a simple model of risk sharing and capital flows across countries assuming that each country cannot commit to fully repay its contract obligations. In the model, the degree of risk sharing and the amount of investment are interdependent. It is...

We study a class of representation mechanisms, based on reports made by a random subset of agents, called representatives, in a collective choice problem with quasi-linear utilities. We do not assume the existence of a common prior probability describing the distribution of preference types. In...

This paper examines the role of liability for past environmental contamination in the privatization processes of Central and Eastern Europe. The theoretical section establishes a link between a risk-averse investor’s amount of information regarding the extent of past environmental...

This paper analyzes a model of capacity choice followed by price competition under demand uncertainty. Under various assumptions regarding the nature and timing of demand realizations, we obtain general predictions concerning the role of demand uncertainty on equilibrium outcomes. We show that...

We consider mean-variance portfolio choice of a robust investor. The investor receives advice from J experts, each with a different prior for the distribution of returns. Confronted with these multiple priors the investor follows a min-max portfolio strategy. We study the structure of the robust...

We take up the discussion started by Condorcet on which voting system yields the highest probability that a good decision is taken. When regional information shocks are taken into account, an Electoral College system has advantages over simple majority vote under certain conditions: The...

We study the problem of a central bank whose policy actions simultaneously affect the information flow about its expectations-augmented Phillips curve and its reputation for toughness in fighting inflation. In an environment with an unknown relationship between inflation surprises and output,...
