The paper utilizes duality theory to derive an exact representation of the core of a supermodular capacity for finite-state-space Choquet expected utility preferences. Using the dual representation we develop an algorithm that uses information on willingness to pay and willingness to sell to...

We identify conditions under which receipt of information in the form of a (potentially) ambiguous signal leads to a smoother maximin expected utility (MEU) preference structure which translates behaviorally into a smaller no-trade price zone. Narrowing of the no-trade price zone depends...

This paper considers the simple neoclassical economics of price gaps in the absence of income effects. Our guiding principle is that price gaps reflect a fundamental economic principle: buy low and sell high. It is demonstrated that neoclassical theory makes clear and economically testable...

Optimal trade policy in an uncertain world is examined. Decision-maker attitudes toward uncertainty are represented in terms of the <link rid="b16">Gilboa-Schmeidler (1989)</link> maximin expected-utility (MMEU) model. The central result is that in a two-country, general-equilibrium setting with both trading partners...

The paper examines principal-agent relationships in uncertain environments where beliefs of the contracting parties (the regulator and the firm) are represented by sets of probabilities. In addition to fully characterizing the first-best and the second-best solutions, we examine optimality of...

We examine the implications of decision theory for religious choice and evangelism, under the assumption that people choose their religion. The application of decision theory leads us to a broad definition of religion and a particular definition of faith, each related to the uncertainty...
