Examining economic and legal aspects of competition policy and industrial organization, the handbook provides a scholarly review of the state of the art for economic theory, empirical evidence, and standards of legal evidence. The 16 contributors are economists and other experts in Germany, the Netherlands, Austria, France, the UK, and the US. The handbook is intended for students of economics and law, public administrators, lawyers, consultants, business managers, and particularly for policy makers in EU accession countries who are required to introduce an appropriate legal framework to implement EU competition policy.
