Competition Policy in the European Union and the Power of Microsoft

by Julio J. Rotemberg and Michelle Kalka


Focuses on a decision by the European Competition Commissioner Mario Monti about U.S.-based Microsoft Corp. Sun has complained to the commission that Microsoft has installed components in its desktop operating system that only "talk" to Microsoft operating systems for servers. Sun has further complained that Microsoft released information about its operating systems to some partners but not to Sun. The commission has issued a formal complaint, but Monti's decision is still pending at the time of the case. As background for this decision, the case contains information about the U.S. antitrust case against Microsoft, U.S. and European competition laws, and how European lawmakers have dealt with interconnections among IT components in the past.
