The Arbitrariness of Market Definition and an Evolutionary Concept of Markets The Antitrust bulletin 61, 1 (2016), 121 - 132.
Market definition is highly relevant in European case practice in competition law. Yet the tools and also the concepts are far from being very sophisticated. The critique of market definition by Richard Markovits is far-reaching: not only is market definition arbitrary, but current approaches also have an in-built bias towards a static snapshot understanding of the economy. Yet it would be wrong to give up this important step in antitrust analysis, since otherwise antitrust loses its function as the fundamental set of governing rules for markets. Instead, it is necessary to develop a more evolutionary concept of markets.
