Conflicts of interest arise between a decision maker and agents who have information pertinent to the problem because of differences in their preferences over outcomes. We show how the decision maker can extract the information by distorting the decisions that will be taken, and show that only...

We analyze a canonical binary-action coordination game under the global games framework. To reduce coordination failure, we propose a novel intervention program that screens agents based on their heterogeneous interim beliefs. Compared with conventional government-guarantee type of programs, it...

Global games of regime change that is, coordination games of incomplete information in which a status quo is abandoned once a sufficiently large fraction of agents attacks it have been used to study crises phenomena such as currency attacks, bank runs, debt crises, and political change. We...

Global games of regime change - that is, coordination games of incomplete information in which a status quo is abandoned once a sufficiently large fraction of agents attacks it - have been used to study crises phenomena such as currency attacks, bank runs, debt crises, and political change. We...

We scrutinize the use of value at risk as traders' limit in banks. Thereby, we compare a bank with uninformed traders dealing on a perfect capital market, with a bank in which traders receive a noisy signal about the future price of the stock they are dealing in. Additionally, they are able to...

Group decision making is commonly used in juries, businesses, and in politics to increase the informational basis for a decision and to improve decision accuracy. Recent work on generalizing Condercet's jury theorem provides a compelling justification for using groups in this manner. But these...

This essay considers the role of reputational information in our marketplace. It explains how well-functioning marketplaces depend on the vibrant flow of accurate reputational information, and how misdirected regulation of reputational information could harm marketplace mechanisms. It then...

We argue that when externalities such as pollution are nonexcludable, agents must be compelled to participate in a “mechanism” to ensure a Pareto-efficient outcome. We survey some of the main findings of the mechanism-design (implementation-theory) literature – such as the Nash...
