MaCCI Law and Economics Conference: Competition Policy of the Web Search Engine Market


The web search engine market is dominated by only a few companies, especially by Google. The European Commission has opened an antitrust investigation in 2010 against the American company which once was so sympathetic. Google is suspected to have abused its predominant market position, e.g. by a better placement of own services in its search results. The Commission further accuses the company of forcing advertising partners to place their whole advertisement via Google and thus restrains the competition between the different search engines. Google has offered to make concessions concerning the pending case. It is still unclear if Google has to pay an antitrust fine.

The antitrust problem of the Google investigation is only one example in the fast-moving markets of the internet industry. The conference is supposed to be a forum for an interdisciplinary discussion on current competition policy issues in the network industry. In the focus will be the problem whether and to what extent antitrust control is appropriate to guarantee a stable functioning of the markets in the area of the differentiated search engine industry, and more generally, in the internet economy, or whether a sector-specific regulation is necessary.

The Leibniz ScienceCampus Mannheim Centre for Competiton and Innovation (MaCCI) is a joint initiative of the School of Law and Economics at the University of Mannheim and the Centre for European Economic Research (ZEW). MaCCI wants to foster the exchange between researchers of law and economy issues within the areas of research on competition policy, regulation, and innovation. MaCCI was launched in 2012 and is jointly funded by the Leibniz Association, the State of Baden-Württemberg, the University of Mannheim, and ZEW.

MaCCI offers many activities: it organises a number of regular events including the MaCCI Annual Conference, the MaCCI Competition Law & Economics Conference, and the Mannheim Competition Policy Forum (MCPF).
