Social environments constitute a framework in which it is possible to study how groups of agents interact in a society. The framework is general enough to analyse both non-cooperative and cooperative games. We identify a number of shortcomings of existing solution concepts that are used for...

We develop a two-person negotiation model with complete information which makes endogenous both the deadline and the level of surplus destruction after the deadline. We show that the equilibrium outcome is always unique but might be inefficient. Moreover, as the bargaining period becomes short...

We analyze a unionized duopoly model to examine how unions affect the incentives for merger. We find that, once the union has the option to delegate, an increase in the union bargaining power can create incentives for the firms to merge.

We develop a model of wage determination with private information, in which te union has the option to delegate the wage bargaining to either surplus-maximizing delegates or to wage-maximizing delegates (such as senior union members). We show that the strike activity is greater whenever the...

We develop a spatial two-country model of wage determination with private information in unionized imperfectly competitive industries. We investigage the effects of separated product markets opening up for competition as well as of further market integration on the negotiated wage and the strike...

Within an incomplete information framework, we develop a model of wage determination in a unionized Cournot oligopoly. The assumption of incomplete information allows the possibility of strikes, which waste industry potential ressources, at equilibrium. Facing such deadweight loss, the...

The objective of this paper is to analyze the relationship between bargaining organizational forms and the licensing of cost-reducing innovations, in order to assess the patent holders optimal policy as well as their welfare properties. Trading mechanisms based on bargaining models with...

This paper reconsiders Rubinstein's alternating-offer bargaining game with complete information. We define rationalizability for multi-stage games with observed actions. Whe show that rationalizability does not exclude perpetual disagreement or delay. Then, we define trembling-hand...

We develop a model of wage determination with private information in a unionized imperfectly competitive industry. Under two different bargaining structures (firm-level vs industry-level), we investigate the effects of the degree of product differentiation and the type of market competition...

We consider efficiency wage effects in a union-firm bargaining model with private information. We show that efficiency wage effects do not necessarily increase the wage level at equilibrium. However, if it is commonly known that the union is stronger than the firm and the productivity enhancing...
