Abstract

The paper aims at outlining the main empirical approaches for assessing market share dynamics. Those embody distinct levels of detail and include generic stationary tests for relative market shares, broader leadership turnover indicators and yet leadership convergence assessments between specific firms in a given industry. The potential role of market share dynamics in competition policy is discussed and tentative guidelines are suggested.
