Expert Economic Testimony, Economic Evidence and Asymmetry of Information in Antitrust Cases

24 octubre, 2007

He publicado mi tesis de maestría “Expert Economic Testimony, Economic Evidence and Asymmetry of Information in Antitrust Cases” en el SSRN. El documento se enfoca en las normas de la Comunidad Europea y de Estados Unidos (a nivel federal) pero espero escribir próximamente un documento en el cual se refleje el mismo debate en relación al sistema de promoción y defensa de la Competencia de Colombia y en general de América Latina y el Caribe.
Espero sus comentarios!

A continuación transcribo los datos relevantes del documento:

ABSTRACT: The objective of this document is to assess two questions that have a positive and normative nature respectively: 1) What incentives does the legal and institutional framework of the European Community (EC) and the United States (federal level) provide to the different agents involved in antitrust proceedings in regards to the use of expert economic testimonies? 2) What legal and social norms could provide appropriate incentives to the different agents involved in antitrust proceedings in order to align the use of expert economic testimonies with antitrust enforcement goals?

To answer the first research question and prepare the settings for the answer of the second question, the nature of the economic expertise applied in antitrust proceedings, its inherent difficulties (section 2), and the legal and institutional framework applied to them (section 3) are presented in detail.

Secondly, a general exposition of the problems posed by asymmetric information in theory (section 4.1) and concerning the relation between the adjudicator and the economic expert (section 4.2) is made, in order lay the foundations to identify the different factors that determine the incentives of the various “actors” in the proceedings (section 4.3). Finally, to answer the second research question, the regulatory and non-regulatory features of US and EC enforcement systems are analyzed to identify which factors mitigate the information asymmetry problems. The different alternatives are presented in three different categories, namely, “evidentiary rules”, “procedural rules and institutional design” and “a market for experts and the academic community” (section 4.4).

The document contains six conclusions that may be summarized in the following statement: regarding expert economic testimonies, an antitrust enforcement system must aim at the minimization of its costs through the mitigation of the consequences of asymmetric information between the adjudicator and the expert. Therefore a cost-benefit analysis of the use of expert witnesses must take into account the incentives produced by the interaction among the different regulatory and non-regulatory features of the antitrust enforcement system.

    A pesar que hace bastante ha publicado este anuncio, le comento que el problema que plantea es muy interesante y trataré de ver algo de su investigación. aunque del abstrac veo que el enfoque es muy económico, por lo cual los resultados jurídicos pueden ser muy inciertos.José Manuel Alvarez
