The effects of mergers with dynamic capacity accumulation

Author

  • Chen, Jiawei

Abstract

The U.S. antitrust law enforcement agencies often base their assessment of mergers on a model with asymmetric costs. However, in many near-homogeneous product industries there is evidence that cost differences are minor and capacity differences seem a more reasonable explanation of firm heterogeneity. Based on simulations from a dynamic model of capacity accumulation, I find that mergers are welfare-reducing and that their long-run effects are worse than their short-run effects. If instead the simulated data is fit to an asymmetric costs model, the long-run welfare-reducing effects of mergers will be systematically underestimated, which can give rise to misguided antitrust policies.
