We analyze the impact of a uniform price cap at electricity spot markets on firms investmentdecisions and on welfare. Since investment decisions for those markets are taken in the longrun, fluctuating demand at the spot market eventually gives rise to high price spikes in case ofbinding...

This paper analyses price competition under product differentiation when goods are defined ina two dimensional characteristic space, and consumers do not know which firm sells whichquality. Equilibrium prices consist of two additive terms, which balance consumers' relativevaluation of goods'...

In this paper we address the following question: is it more profitable, for an entrant in a differentiatedmarket, to acquire an existing firm than to compete? We illustrate the answer by considering competition inthe banking sector.....

The paper examines the Porter and induced-innovation hypotheses in a firm model where: (i) the firmhas a vintage capital technology with two complementary factors, energy and capital ; (ii) scrappingis endogenous; (iii) technological progress is energy-saving and endogenous through purposive...

This paper faces two questions concerning Joint Ventures (JV) agreements. First, we studyhow the partners contribution affect the creation and the profit sharing of a JV when partners'effort is not observable. Then, we see whether such agreements are easier to enforce when thedecision on JV...

We analyze a model of resource allocation in which agents' abilities (to transform the resourceinto an interpersonally comparable outcome) and initial endowments may differ. We imposeethical and operational axioms in this model and characterize some allocation rules as a resultof combining these...

We analyse firms' incentives to provide two-way compatibility between two network goodswith different intrinsic qualities. We study how the relative importance of verticaldifferentiation with respect to the network effect influences the price competition as well as thecompatibility choice. The...

In order to capture observed asymmetric dependence in international financial returns, we construct amultivariate regime-switching model of copulas. We model dependence with one Gaussian and onecanonical vine copula regime. Canonical vines are constructed from bivariate conditional copulas...

We propose a tactical model which integrates the replenishment decision in inventorymanagement, the allocation of products to warehousing systems and the assignment of products tostorage locations in warehousing management. The purpose of this article is to analyse the valueof integrating...

Former generation capacity expansion models were formulated as optimization problems. Theseincluded a reliability criterion and hence guaranteed security of supply. The situation is differentin restructured markets where investments need to be incentivised by the margin resulting fromelectricity...
