Abstract:	This research modifies the well-known three-stage merger simulation procedure of Nevo (2000) by replacing demand analysis in the first stage with survey-generated diversion ratios and own-price elasticities. We also provide a post-merger price formula under the scenario of two firms competing in the same relevant market and operating independently of the other firms in the relevant market. The same scenario is considered in upward pricing pressure (UPP) and commonly observed in most filing cases for mergers, where the competition enforcers can only have access to these two firms’ data most of the time. Since the formula is exact and requires only data on price and own-price elasticity of each firm and the diversion ratios between these two firms, our approach’s implementation cost is almost identical to that used in critical loss analysis, the diversion ratio, and UPP. The formula thus is informative and convenient for competition enforcement when dealing with merger cases.
