We analyse the optimal pricing choice of an incumbent firm that sells a good with network externalities and is threatened by the entry of a higher quality variant. In the framework of a vertical differentiation model, we find a necessary and sufficient condition under which quality improvement...

In this article, we consider a demand model for a durable good with unknown quality. The quality of the good is uncertain in the sense that the consumer ignores (ex ante) whether the good will break down or not, higher quality implying a higher probability of survival. Taking into account this...

This paper characterizes the optimal redistributive taxation when individuals are heterogeneous in two exogenous dimensions : Their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are...

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

An inductive procedure is adopted to evaluate the behaviour of a multiproduct profit seeking monopolist vis à vis that of a social planner, in a model where there is a continuum of consumers characterized by different marginal willingness to pay for the quality. When the market is completely...

We propose a model representing a newspaper producer supplying a product which can be acquired by the readers either every day per one unit at a time, or by subscription. The population of potential buyers is differentiated according to the frequency at which they want to read the newspaper....

Despite increasing flows of foreign direct investment (FDI), an important gap still exists between FDI toward Central and Eastern European countries (CEECs) and their actual needs to support structural adjustment. Using a Cournot duopoly model with a profit-maximizing foreign-based multinational...

This paper studies the strategic role of foreign direct investment (FDI) in a framework with early-on capacity investments by a multinational enterprise (MNE) and relevant fixed costs. A three-stage game is considered : (i) MNE chooses internationalisation mode, and output to precommit by...

This article examines why, and how, fiscal decentralization could increase the economic growth rate (the hypothesis is predatory, or "corrupt", govemments). Searching for the optimal level of decentralization, the article first investigates the effects of an horizontal partition of the political...
