A recent TILEC discussion paper by Laura Parret (TILEC) presents an original perspective on a classical legal theme, namely rules on proof. Such rules might be perceived by some economists as formalistic, or overly complicated. However, the paper argues that they are necessary to ensure the protection of higher principles, such as the presumption of innocence and proportionality. In addition, the case is made that the importance of such rules has increased since the promotion of a more economic approach to competition law. At the same time, lawyers should also avoid being too formalistic: there is no pressing need for a "right" standard of proof to be defined, contrary to what some lawyers are claiming after ECJ judgments such as Tetra
Laval. Lawyers should accept that the current standard is workable and sufficient as a basis, at least in cartel cases. Decision-makers can handle flexible and differentiated rules, and should be trusted to do so. However, it is essential for authorities and courts to adequately motivate their decisions, to be accountable both to the companies concerned and to the general public, and not in the least to allow for efficient judicial review. A revised version of the paper is forthcoming in the European Competition Journal.
Is market monitoring sufficient to prevent financial crises?

TILEC researchers come CLEEN
Amrita Ray Chaudhuri, Filomena Chirico and Alan Littler will represent TILEC at a workshop held at the University of East Anglia from 11 to 13 June 2008, organized within the CLEEN framework. CLEEN, the Competition Law and Economics European Network, was established in 2007 as a network of research institutions dealing with competition policy from a legal and economic perspective. The first academic meeting of the network was held in Bonn in December 2007 at the initiative of the Max-Planck Institute for research on collective goods. This meeting will be the second event under the banner of CLEEN, and will be hosted by the Center for Competition Policy (CCP) of the University of East Anglia in Norwich. On this occasion, the meeting will be especially targeted at young researchers. The workshop will give them a possibility to present a sample of their recent research, as well as receive valuable comments from an interdisciplinary and international audience, two qualities that TILEC is proud to be associated with.
Do exclusivity contracts hamper product innovation?
Contractual relationships at various levels in the production chain, although often efficient, may at times be used for anti-competitive purposes. In particular, exclusivity clauses have long been regarded with suspicion because of their direct exclusionary effects. Over the past decades, economists and lawyers have come to a better understanding of the possibilities for dominant firms to use such arrangements so as artificially to maintain their position. Recent pieces have suggested that intense competition among downstream buyers may be enough to prevent dominant upstream firms to seize them. In a recent TILEC discussion paper, Cédric Argenton (TILEC) revisits the main theory of harm (the so-called "naked exclusion" story) in the case when the efficient competitor is not a firm producing at a lower cost but one bringing an innovative, higher-quality product to the market. Contrary to the case of process innovation, when retailers intensely compete with one another, the incumbent firm is always able to exclude the innovative firm. Therefore, intense competition at the retail level is no guarantee that exclusivity contracts are harmless. Competition policy enforcers need to pay more attention than ever to the exact characteristics of the upstream market.
Does competition really serve consumers?
