We develop a theoretical model of retail competition that include two sources of quality, one inherently linked to brand characteristics and the other linked to the retailer level of service. We then measure their contribution in explaining the observed price differentials for a sample of U.K....

We study different extended formulations for the set (formule) in order to tackle the feasibility problem for the set (formule). Here the goal is not to find an improved polyhedral relaxation of conv(X+), but rather to reformulate in such a way that the new variables introduced provide good...

We study the endogenous formation of networks between manufacturers of differentiated goods and multi-product retailers who interact in a successive duopoly. Joint consent is needed to establish and/or maintain a costly link between a manufacturer anda retailer. We find that only three...

We develop a model of strategic networks in order to analyze how trade unions will affect the stability and efficiency of R&D collaboration networks in an oligopolistic industry with three firms. Whenever firms settle wages, the complete network is always pairwise stable and the partially...

We consider a two-country model of wage determination with private information in unionized imperfectlycomp etitive industries. We investigate the effects of separated product markets opening up for competition as well as of further market integration on the negotiated wage and the maximum...

Since the introduction of a formal commitments procedure in EU an- titrust policy (Article 9 of Council Regulation 1/2003), the European Commission has extensively settled cases of alleged anticompetitive practices. In this paper, we use a formal model of law enforcement (Be- bchuk, 1984; Shavell,...

The plea bargaining procedure, namely the viability of a stage of bargaining between prosecutor and defendant in criminal suits, is analyzed in the framework of a two-sided incomlete information game.
