Bargaining under uncertainty is modeled by the assumption that thereare several possible states of nature, each of which is identied with abargaining problem...

We study environmental policy for a polluting firmthat can invest in extracapacity. The optimal levels of allowed output as well as the tax rate are increasingin investment. With divisible investment, commitment always leads to the first best,under direct regulation and taxation. Time-consistent...

We model a general choice environment via probabilistic choice correspondences, with (possibly)incomplete domain and infinite universal set of alternatives. We offer a consistency restrictionregarding choice when the feasible set contracts. This condition, ‘contraction consistency’,...

This note provides an alternative proof of a known result on the existenceof collections of orderings generating intersection quasi-orderings. Instead of proving theresult from rst principles, it is illustrated how it can be obtained by making use of ananalogous relationship between partial...

Discounting the utilities of future people or giving smaller weights to groups other thanone's own is often criticized on the grounds that the resulting objective function diers fromthe ethically appropriate one...

This paper provides an analysis of individual and social decision criteria foralternatives that are composed of several attributes. We derive additive and multiplicativecriteria for individual decision-making with new axioms and apply these criteria toobtain new justications of known social...

This paper provides an analytical framework for exploring the relationshipbetween equity and efficiency for two riparians sharing a transboundary river.Decreasing marginal productivities of water make a noncooperative approach inefficientwhen water is scarce. If the upstream riparian uses its...

We examine the implications of an income redistribution from men to women for the welfare ofmothers and their children. We develop a Cournot model of a two-person household whereagents provide market labor and allocate their spending between a private consumption good andgoods for children. We...

We suggest an alternative way of analyzing the canonical Bergstrom-Blume-Varian model of non-cooperative voluntary contributions to a public goodthat avoids the proliferation of dimensions as the number of players is in-creased. We exploit this approach to analyze models in which the...

We examine a Stackelberg game where a financially constrainedleader faces competition from a ‘deep pocket’ follower. We analyzethe consequences of this trade-off between a financial and a strategicadvantage for both the design of financial contracts and market structure.We derive conditions...
