In this paper a contest game with heterogeneous players is analyzed in which heterogeneity could be the consequence of past discrimination. Based on the normative perception of the heterogeneity there are two policy options to tackle this heterogeneity: either it is ignored and the contestants...

It is well-known that couples that look jointly for jobs in the same centralized labor market may cause instabilities. We demonstrate that for a natural preference domain for couples, namely the domain of responsive preferences, the existence of stable matchings can easily be established....

Strategy-proof social choice functions are characterized for societies where the space of alternatives is any full dimensional compact subset of a Euclidean space and all voters have generalized single-peaked preferences.

A key issue multicriteria evaluation in a fuzzy environment is how to compare fuzzy numbers. In this paper, the case of criterion scores in the form of L-R fuzzy numbers, i.e. the most general form of fuzzy numbers, will be considered.

We address the question of how a third-party payer (e.g. an insurer) decides what providers to contract with. Three different mechanisms are studied and their properties compared. A first mechanism consists in the third-party payer setting up a bargaining procedure with both providers jointly...

The stationary structure of the simple overlapping generations economies is used to try to extend to the case with extrinsic uncertainty the characterizations of their stationary equilibria by means of symmetrical multiple equilibria of a related exchange economy in which the representative...

An assesment aggregation rule is a mechanism which collapses several individual assessments ("quantitative opinions") into a unique ("collective") assessment. Individual i can manipulate assessment aggregation if the change in the aggregated assessmentdue to a change in i's assesment from x to...

We examine in this paper the formation and the stability of international environmental agreements when cooperation means to commit to a minimum abatement level. Each country decides whether to ratify the agreement and this latter enters into force only if it is ratified by a number of countries...

We study a problem of adverse selection in the context of environmental regulation, where the firm may suffer from a certain degree of ignorance about its own type. In a framework like the construction of a certain infrastructure project, the presence of ignorance about its impact on the...

Cost-benefit analysis (CBA) is the most popular evaluation tool in economics. However, it is widely recognised that one of its main limitations is the impossibility of splitting efficiency and equity issues. The present paper, from an economic theoretical point of view, will present a...
