Extensions - Supplement to "The Costs of Environmental Regulation in a Concentrated Industry"
Stephen P. Ryan
Description: This appendex discusses identification of the model in the paper. New results concerning the identification of parameters in a two-step Bajari, Benkard, and Levin (2007) setup are given. Under linearity of the unknown parameters, it is shown that identification obtains when an easily-verified rank and order condition on a matrix derived from estimated functions holds.
