Abstract

This online appendix contains the derivation of the closed form solutions for the examples used in the main working paper No. 16-002. It establishes the result stated in Section 4.3 of the main paper, that Proposition 4 continues to hold even if the price is endogenous and there are production costs. It provides the proofs of some results stated in the extensions section of the paper. It also details the numerical analysis performed to check the robustness of the first part of Corollary 1 to the introduction of private benefits and spillovers.

The paper "Enabling versus Controlling" to which these Appendices apply is available at the following URL: http://ssrn.com/abstract=2627843
