This paper builds a theory of profit sharing between two firms in a duopoly market through which firms seek to increase their profits and, in turn, to limit the competition. We use a general model to show the direct (negative) and indirect (positive) effects of this strategy. We then focus on...

We prove that for generic plurality games with positive cost of voting, the number of Nash equilibria is finite. Furthermore all the equilibria are regular, hence stable sets as singletons.

The divergence between the willingness-to-pay (WTP) and willingness-to-accept (WTA) has resulted in two explanations. First, that this may be due to the manifestation of the endowment effect (Kahneman, Knetsch and Thaler, 1991). Second, the difference between WTA and WTP is directly related with...

We address the question of endogenous financing of the Universal Service Obligations and we compare it with the exogenous financing. A fund is created and fed through a tax firms pay. We show that the way these funds are implemented by the current regulatory regimes at work goes against the...

This paper provides a general framework for the simulation of stochastic dynamic models. Our analysis rests upon a continuity property of invariant distributions and a generalized law of large numbers. We then establish that the simulated moments from numerical approximations converge to their...

We examine firms' incentives to protect their non-cooperative R&D investments from spilling over to competitors. Contrary to most of the existing literature, we show that the lack of full appropriability can lead to an increase in R&D investments. We also show that even if protection is...

We study a model in which an inventor discloses knowledge about its innovation and then a rival chooses the probability of attaining a competing invention. Disclosures, by creating prior art, diminish the probability that the rival has of receiving a patent for its invention (legal externality),...

In this paper we study incentives for a government to impose a discriminatory or uniform import tariff on its low and high quality imports. In comparison to free trade both tariffs decrease total welfare. In response to any tariff, firms decrease quality investment and total output sold...

We examine a final product manufacturer's incentives to engage in exclusive dealing with an input supplier when both market sides invest in quality and bargain over their trading terms. Taking into account that the investments' compatibility can be higher under exclusive dealing we find, in...

Does electoral competition make candidates reveal information that voters value? I study this question in a Downsian model of a repeated election consistent with six stylized facts of US Presidential Elections: (i) there are two candidates/parties, (ii) they are longlived, (iii) there is...
