Most economic analyses presume that there are limited differences in the prior beliefs of individuals, as assumption most often justified by the argument that sufficient common experiences and observations will eliminate disagreements. We investigate this claim using a simple model of Bayesian...

Owners of intellectual property or mere sponsors of an idea (e.g., authors, security issuers, sponsors of standards) often need to persuade potential buyers or adopters of the worth of their property or idea. To this purpose, they often resort to more or less independent certifiers. This paper...

Societies under similar geographic and economic conditions and subject to similar external influences nonetheless develop very different types of states. At one extreme are weak states with little capacity and ability to regulate economic or social relations. At the other are despotic states...

This chapter develops a unified framework for the study of how network interactions can function as a mechanism for propagation and amplification of microeconomic shocks. The framework nests various classes of games over networks, models of macroeconomic risk originating from microeconomic...

Building on theories of international relations, we analyze how mistrust (uncertainty about an adversary's preferences or capabilities), misperception (imperfect observation of an adversary's actions), and misunderstanding (non-degenerate higher-order beliefs) can lead to conflict and drive its...

We propose a model of the interplay of employment relationships and community-based interactions among workers and managers. Employment relations can be either tough (where workers are monitored intensively and obtain few rents, and managers do not provide informal favors for their workers) or...
