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...

Global income taxation in the country of residence is a legal dogma of international taxation. We question this dogma from the perspective of relations with developing countries from a legal and economic perspective, and make a modern and fair proposal for tax treaties. We will show under which...

In this paper, we consider a population of individuals who differ in two dimensions: their risk type (expected loss) and their risk aversion. We solve for the profit maximizing menu of contracts that a monopolistic insurer puts out on the market. First, we find that it is never optimal to fully...

This paper provides a general overview of the literature on the core of an exchange economy with asymetric information. Incentive compatibility is emphasized in studying core concepts at the ex ante and the interim stage.The analysis includes issues of non emptiness of the core as wellas core...

We consider the effect of asymmetric information on price formation process in a financial market where private information is held by a market maker. A Bayesian game is proposed in which there is price competition between two market makers with two different information partitions. At each...

A country consists of two non-overlapping regions, each ruled by a local authority. The federal government plans to construct a facility in one of the regions. If the facility is constructed, it generates a social value in the host region and has spillover effects in the rest of the country. The...
