We develop a model that combines competitive exchange of private commodities across endogenously formed groups with public good provision and global collective decisions. There is a tension between local and global collective decisions. In particular, we show that group formation and collective...

It has long been known that when agents have von Neumann-Morgenstern preferences over lotteries, there is an incompatibility between strategy-proofness and efficiency (Gibbard, [9]; Hylland, [12]) - a solution satisfying those properties must be dictatorial. We strengthen this result by showing...

Public policy may influence norms and preferences. By altering the payoffs associated with different preferences, public policy may influence the distribution of these preferences in the population. Such interdependence between policy and preferences may limit (or enhance) the effectiveness of...

The determinants of government responsiveness to its citizens is a key issue in political economy. Here, we develop a model based on the solution of political agency problems. Having a more informed and politically active electorate strengthens incentives for governments to be responsive. This...

Identification of a deleterious impact of institutions of direct legislation on student performance by studies for both the U.S. and Switzerland has raised the question of the exact transmission channels for this impact. Studies for the U.S. that find an increase in the ratio of administrative...

In the single-peaked domain, the median rules (Moulin, 1980) are of special interest. They are, essentially, the unique strategy-proof rules as well as the unique Nash implementable ones under complete information. We show that, under mild assumptions on admissible priors, they are also...
