Antitrust Analysis with Upward Pricing Pressure and Cost Efficiencies

By: Jessica Dutra (Department of Economics, The University of Kansas); Tarun Sabarwal (Department of Economics, University of Kansas)
Abstract: We investigate the accuracy of UPP as a tool in antitrust analysis when there are cost efficiencies from a horizontal merger. We include model-based, merger-specific cost efficiencies in a tractable manner and extend the standard UPP formulation to account for these efficiencies. The efficacy of the new UPP formulations is analyzed using Monte Carlo simulation of 40,000 mergers (8 scenarios, 5,000 mergers in each scenario). We find that the new UPP formulations yield substantial gains in prediction of post-merger prices, and there are substantial gains in merger screening accuracy as well. Moreover, the new UPP formulations outperform the standard UPP formulation at higher thresholds for all the standard cases in the paper. The results support the inclusion of model-based cost efficiencies in the standard UPP formulation for more accurate antitrust decision-making.
