Import price elasticity tends to be under-estimated due to the omission of quality effects. This dissertation aims to fill this gap by analyzing 1) how quality effects affect the estimation of import price elasticity, 2) the impact of quality innovation in the various goods sectors of an economy...

The paper analyzes the efficiency of extended producer responsibility (EPR) for waste management. We consider a vertically differentiated duopoly where endogenous market quality affects waste disposal costs. Each producer has to meet a take-back requirement that forces it to collect and treat...

Traditional trade models ignoring the dimension of product quality generally lead to excessively low trade price elasticities. In this paper, we show that higher estimated trade price elasticities, more in conformity with theory, can be obtained by controlling product quality in trade equations....

How are eco-label strategies affected by consumer confusion arising from the profusion of eco-labels? This article provides a theoretical insight into this issue using a double differentiation framework. We assume that consumers perceive a label as a sign of quality compared to an unlabeled...

This article deals with the impact of legislation in the seed sector on incentives for variety creation. The first category of rules consists in intellectual property rights and is intended to address a problem of sequential innovation and R&D investments. The second category concerns commercial...

In this paper, we analyze the effect of Cournot competition with differentiated products on the real and financial decisions of a publicly-owned firm, with three different structures in the financial market : monopoly, duopoly and Stackelberg. We shows that the degree of product differentiation...

We study international competition in high-end products for 416 detailed HS6 product categories marketed by leading French luxury brands. We construct a world database of trade flows for these products in the period 1994-2009, computing unit values of related bilateral trade flows and analyzing...

The paper analyzes the efficiency of extended producer responsibility (EPR) for waste management. We consider a vertically differentiated duopoly where endogenous market quality affects waste disposal costs. Each producer has to meet a take-back requirement that forces it to collect and treat...

Why do "made in"labels matter? We study the effect of firm and country reputation on exports when buyers cannot observe quality prior to purchase. Firm-level demand is determined by expected quality, which depends on both past experience with the good and the country of origin's reputation for...

The "Elimination by aspects" (EBA) duopoly of product differentiation (Laurent, 2006a) was constructed from the discrete model of probabilistic choice worked out by Tversky (1972a,b). In this framework, an unique price equilibrium exists with a "differentiation by attributes", which embodies...
