Summary
This paper critically views a number of econometric methods that have been utilized in investigations by competition agencies and in private litigation. The focus is on market definition and unilateral competitive effects. Specific topics include critical-loss analysis, price-correlation analysis, merger simulation, and difference-in-differences analysis. When used appropriately and with caution, each of these methodologies can be of substantial value.
