Committees improve decisions by pooling independent information of members, but promote manipulation, obfuscation, and exaggeration of private evidence when members have conflicting preferences. We study how self-interest mediates these conflicting forces. When members' preferences differ, no...

I provide a theoretically-guided discussion of the dynamics of human behavior, focusing on the importance of culture (socially-learned information) and tradition (transmission of culture across generations). Decision-making that relies on tradition can be an effective strategy and arises in...

Policymakers can take actions to prevent local conflict before it begins, if such violence can be accurately predicted. We examine the two countries with the richest available sub-national data: Colombia and Indonesia. We assemble two decades of fine-grained violence data by type, alongside...

Mechanism design teaches us that a mediator can strictly improve the chances of peace between two opponents even when the mediator has no independent resources, is less informed than the two parties, and has no enforcement power. We test the theory in a lab experiment where two subjects...

Regulation of economic activity is ubiquitous around the world, yet standard theories predict it should be rather uncommon. I argue that the ubiquity of regulation is explained not so much by the failure of markets, or by asymmetric information, as by the failure of courts to solve contract and...

The spectacular failure of top-rated structured finance products has brought renewed attention to the conflicts of interest of Credit Rating Agencies (CRAs). We model both the CRA conflict of understating credit risk to attract more business, and the issuer conflict of purchasing only the most...

We collect data on the rules and practices of financial and conflict disclosure by politicians in 175 countries. Although two thirds of the countries have some disclosure laws, less than a third make disclosures available to the public. Disclosure is more extensive in richer and more democratic...

The paper provides an integrated analysis of globalization effects on the inflation-output tradeoff and monetary policy in the New-Keynesian framework. The prediction of the analysis is threefold. First, labor, goods, and capital mobility flatten the Phillips curve, the tradeoff between...

We examine the mechanics of deterrence and intervention when fear is a motive for conflict. We contrast results obtained in a complete information setting, where coordination is easy, to those obtained in a setting with strategic risk, where players have different assessments of their...

We examine whether women and men of the same ability differ in their decisions to seek challenges. In the laboratory, we create an environment in which we can measure a participants performance level (high or low), where a high performance level participant has on average higher earnings from...
