The paper studies managerial incentives in a model where managers choose product market strategies and make takeover decisions. The equilibrium contract includes an incentive to increase the firm's sales, under either quantity or price competition. This result contrasts with previous findings in...

A unified approach to the problems of bargaining with a reference point and of bargaining with claims is addressed. Then, two solutions are reexamined from this perspective: the lexicographic egalitarian and the lexicographic claim-egalitarian. New characterization results are also provided.

This paper studies a strategic model of growth in which firms' accumulation and technological decisions are subject to both friction and external effects. This gives rise to a wide multiplicity of equilibrium behavior, which is consistent with quite different performances of the economy (e.g.,...

In this paper we study the problem of fair allocation in economies with indivisible goods, dropping the usual restriction that one agent receives at most one indivisible good. We show that most of the results obtained in the literature do not hold when the above mentioned restriction is dropped.

This paper considers Nash equilibria of a game played by two populations. Stability of the mixed equilibria is diacU8aed for a wide class of differential systems describing the evolutionary dynamics of behavior. The main property of the Systems under consideration is that every Nash equilibrium...

We study an income tax enforcement problem using a principal agent model where the government sets the tax and inspection functions. These functions are announced to the agents and there is no commitment problem. The penalty function for dishonest taxpayers is given exogenously and must satisfy...

This paper deals with the existence and properties of the demand correspondence when agents' preferences are pseudotransitive. It is shown that a consumption plan belongs to the demand mapping if and only if it is a maximizer of a real-valued weak utility function. Further properties, as...

Two solution concepts have been proposed for bargaining problems with claims, namely, the proportional solution, introduced by Chun & Thomson (1992), and the extended claim-egalitarian solution, [see Bossert (1993) and Marco (1993)]. Neither of these solutions exhaust all possible gains from...

This paper analyzes the existence of efficient equilibrium allocations in an economy with many convex and non-convex firms. A Social Equilibrium is defined as a price vector and an allocation satisfying the following properties: a) Consumers satisfy their preferences, subject to their budget...

The purpose of this paper is to offer an exposition of the results on the existence and optimality of equilibria when production sets are not assumed to be convex, in a general equilibrium framework. We aim at providing a formal and systematic account of the main results available, rather than...
