We start from an aggregate random coefficients nested logit (RCNL) model to provide a systematic comparison between the tractable logit and nested logit (NL) models with the computationally more complex random coefficients logit (RC) model. We first use simulated data to assess possible...

We analyse the determinants of opposition to biotechnology and pharmaceutical patents granted by the European Patent Office between 1978–96. Opposition can be considered an early form of patent validity challenge suit. In our sample, 8.6% of the patents are attacked in opposition proceedings....

This Paper exploits the unique experiment of European market integration to investigate the relationship between integration and price convergence in international markets. Using a panel data set of car prices we examine how the process of integration has affected cross-country price dispersion...

We quantify the competitive effects of removing vertical restraints, based on the recent proposals to liberalize the selective and exclusive distribution system in the European car market. We estimate a differentiated products demand system for new cars and specify a model of oligopoly pricing...

This Paper analyses the impact of retail mergers on product variety. We show that a merging firm may want to enhance its buyer power vis a vis suppliers by delisting products and committing to a ‘single-sourcing’ purchasing strategy. Anticipating this, suppliers will strategically choose to...

In this Paper we analyse the effects of information leakage on the incentives to innovate in firms. We analyse a situation in which an employee in a firm is inspired with a new idea for a product. In a framework in which Intellectual Property Rights on ideas are absent, we analyse the...

The purpose of this paper is to try to shed some new light on the current industrial policy crisis. This paper proposes that the industrial policy debate is shaped by knowledge about the functioning of the underlying industrial structure, which in turn is the Gegenstand of scholars in the field...

An important element of the cost of distance is time taken in delivering final and intermediate goods. We argue that time costs are qualitatively different from direct monetary costs such as freight charges. The difference arises because of uncertainty. Unsynchronized deliveries can disrupt...

In this paper firm level data are used to test whether competition affects productivity performance in three transition countries, Hungary, Romania and Slovenia. The data are based on interviews taken in more than 300 state-owned, privatized and newly-established private firms between September...

Using a comprehensive data set of Portuguese manufacturing firms, we show that the firm size distribution is significantly right-skewed, evolving over time toward a log-normal distribution. We also show that selection accounts for very little of this evolution. Instead, we propose a simple...
