The Effects of Mergers with Dynamic Capacity Accumulation

    (Department of Economics, University of California-Irvine)

We investigate the price and welfare effects of mergers through simulations using a dynamic model of capacity accumulation in which firms produce near-homogeneous products and compete in prices. We find that mergers are welfare-reducing and that their long-run effects are worse than their short-run effects: in the long run average price increases further while total surplus and consumer surplus decrease further. A key feature of the model is that firms are ex ante identical but the industry evolves towards an asymmetric size distribution. If we instead fit the simulated data with an asymmetric costs model, which is a standard approach to explaining persistent asymmetries in market shares, we will systematically underestimate the long-run welfare-reducing effects of mergers, giving rise to misguided antitrust policies.
