Supplement to "The Costs of Environmental Regulation in a Concentrated Industry"

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.
