This paper examines capacity-constrained oligopoly pricing with sellers who seek myopic improvements. We employ the Myopic Stable Set stability concept and establish the existence of a unique pure-strategy price solution for any given level of capacity. This solution is shown to coincide with...

This paper proposes a spatial model of imperfect competition in markets with selection to investigate whether imperfect competition exacerbates or offsets inefficiencies caused by selection. We find that no degree of imperfect competition achieves the first-best efficient allocation. This holds...

This paper studies the impact of income inequality on the level of innovative activities in a model where innovations result in quality improvements. The market for quality goods is characterized by a natural oligopoly with three types of consumers - rich, middle class and poor. In general, we...

This paper explores the impact of product liability on vertical product differentiation when product safety is perfectly observable. In a two-stage competition, duopolistic firms are subject to strict liability and segment the market such that a low-safety product is marketed at a low price to...

In this paper, we study the rational for an incumbent to launch a second brand when facing potential entry in a market with quality differentiated products and a fringe producer. Depending on market size, costs for a second brand and a potential entrant’s setup cost the incumbent might use a...

This paper explores the impact of product liability on vertical product differentiation when product safety is perfectly observable. In a two-stage competition, duopolistic firms are subject to strict liability and segment the market such that a low-safety product is marketed at a low price to...

Using data on product-level prices matched to the producing �rm�s unit labor cost, we reject the hypothesis of a full and immediate pass-through of marginal cost. Since we focus on idiosyncratic variation, this does not �t the predictions of the Ma´ckowiak and Wiederholt (2009) version of...

This paper surveys the recent literature devoted to the analysis of the interactions between the adoption of voluntary or negotiated agreements as a tool of environmental policy and market structure. The goal of this survey is twofold. On the one hand, we would like to identify the market...

We study international trade of innovative goods subject to scientific uncertainty on consumers' health effects. Trade of these goods is often at the centre of international disputes. We show that a new trade protectionism may arise because of the scientific uncertainty. A free riding effect is...

Tying arrangements recently have been a major and contentious issue in many high profile antitrust cases in the US and Europe. Examples include the Microsoft case, the Visa and MasterCard case, and the proposed GE/Honeywell merger to name a few. This paper conducts a selective review of the...
