The humble idea that experts are ordinary human beings leads to surprising conclusions about how to get the best possible expert advice. All too often, experts have monopoly power because of licensing restrictions or because they are government bureaucrats protected from both competition and the...

This paper analyzes the implications of currency crises in a model with unique equilibrium. Starting from a typical multiple equilibria model with self-fulfilling expectations we introduce noisy information, following Morris/Shin (1999). Under certain conditions for the noise parameter, all...

This paper compares the link between exchange rates and interest rates under full information and two alternative asymmetric information approaches. It also distinguishes between cases of expansionary and contractionary depreciations. Full information results are not robust to the presence of...

The assumption of asymmetric and incomplete information in a standard New Keynesian model creates strong incentives for monetary policy transparency. We assume that the central bank has better information about its objectives than the private sector, and that the private sector has better...

This paper presents several economic models that explore the relationships between imperfect information, racial income disparities, and segregation. The use of race as a signal arises here, as in models of statistical discrimination, from imperfect information about the return to transactions...

Numerous laboratory experiments show that workers reciprocate to high wages with high effort, when there is perfect information on the surplus created. Recent field experiments, however, suggest that trust and reciprocity may be lower or absent when the information is incomplete. We report a...

An appropriate (interim) notion of the core for an economy with incomplete information depends on the amount of information that coalitions can share. The coarse and fine core, as originally defined by Wilson (1978), correspond to two polar cases, involving no information sharing and arbitrary...
