We study the emergence of norms of cooperation in experimental economies populated by strangers interacting indefinitely. Can these economies achieve full efficiency even without formal enforcement institutions? Which institutions for monitoring and enforcement facilitate cooperation? Finally,...

The need for efficient coordination is ubiquitous in organizations and industries. The literature on the determinants of efficient coordination has focused on individual decision making so far. In reality, however, teams often have to coordinate with other teams. We present a series of...

We show that isolated capital cities are robustly associated with greater levels of corruption across US states, in line with the view that this isolation reduces accountability. We then provide direct evidence that the spatial distribution of population relative to the capital affects different...

A key feature of arbitration is the possibility for con icting parties to participate in the selection of the arbitrator, the individual who will rule the case. We analyze this problem of the selection of arbitrators from the perspective of implementation theory. In particular, theoretical...

Policy developers can appeal to a decision maker by making productive investments to improve the quality of their proposals. These investments are specific to a...

In this paper we analyze elections when voters underestimate the correlation between their information sources ("correlation neglect"). We find that this cognitive bias can improve political outcomes. We show that the extreme beliefs which result from correlation neglect induce some voters to...
