What is the effect of product market integration on the market equilibrium in the presence of international network externalities in consumption? To address this question, we set up a spatial two-country model and we find that the economic forces at work may have an ambiguous effect on prices.

We develop a model of wage determination with private information, in which the 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 wage outcome in case of surplus-maximizing...

We develop a model of strategic networks in order to analyze how trade unions will affect the stability of R&D networks through which knowledge is transmitted in an oligopolistic industry. Whenever firms settle wages, the partially connected network is likely to emerge in the long run if and...

We consider an economy in which a central government has to decide on the provision and location of an emergency public service the quality of which diminishes with distance. The emergency service has to attend a group of municipalities geographically located in a star-tree-graph. We derive the...

Curb sets [Basu and Weibull, Econ. Letters 36 (1991), 141-146] are product sets of pure strategies containing all individual best-responses against beliefs restricted to the recommendations to the remaining players. The concept of minimal curb sets is a set-theoretic coarsening of the notion of...

We consider a two-country model of wage determination with private information in unionized, imperfectly competitive, industries. We investigate the effects of opening up markets to trade as well as of further market integration on the negotiated wage and the maximum delay in reaching an...
