LAW & ECONOMICS: SUBSTITUABILITY - PRICE ELASTICITY - MARKET DEFINTION - CASE LAW

Demand and elasticities: How to assess the relevant market ?

This paper is the print version of the talk given by Professor Louis Vogel and Me Joseph Vogel at the first session of the training cycle “Economics and competition law” launched by Concurrences Review, on 28 October 2009 in Paris, on substituability.

Each session is credited two hours for the Paris Bar Lawyers continuing education. The program of the sessions appears below.
