The cyclical behavior of hours worked, wages, and consumption does not conform with the prediction of the representative agent with standard preferences. The residual in the intra-temporal first-order condition for commodity consumption and leisure is often viewed as a failure of labor-market...

Starting from the European option valuation framework of Chauveau & Gatfaoui (2002), we establish the link with stochastic volatility models. And, we propose both a new vision and a general framework for valuing European options in the light of systematic and idiosyncratic risks affecting risky...

We analyze models of product differentiation with perfect price discrimination and free entry. Although perfect price discrimination ensures efficient output decisions given product characteristics, coordination failures may prevent efficiency in the choice of product characteristics. More...

Comparative advertising by one brand against another showcases its merits versus the demerits of the other. In a two-stage game among finitely many firms, firms decide first how much to advertise against whom. In the second stage, given the advertising configuration, firms compete as Cournot...

A monopoly selling in two countries can use exclusive or competitive retailers to distribute its product. A low wholesale price in one country might induce a retailer to resell the good for profit in the other country, generating thereby parallel imports which compete with the authorized sales....

We analyze the effects of a legally-binding price floor using Hotelling's model of locational competition. A moderate price-floor destroys the maximal differentiation equilibrium of d'Aspremont et. al., by allowing firms to compete more aggressively for market share. Minimum differentiation...

Comparative advertising by one brand against another showcases its merits versus the demerits of the other. In a two-stage game among finitely many firms, firms decide first how much to advertise against whom. In the second stage, given the advertising configuration, firms compete as Cournot...

This paper analyzes the incentives for governments to impose export subsidies when firms invest in a cost saving technology before market competition. Governments first impose an export subsidy or a tax. After observing export policy, firms invest in cost reducing R&D and subsequently compete in...

We study the effect of market structure upon international trade policy when firms invest in process R&D before competing in a differentiated goods market. For a domestic monopoly, and increasing the number of foreign firms, the government either chooses a R&D (and output) subsidy, or remains...
