An Economic Analysis of Trade-Secret Protection in Buyer-Seller Relationships

The economic analysis of trade-secret protection has traditionally focused on the interests of companies to conceal information from competitors in order to gain a competitive advantage through trade-secret law. This has neglected cases in which the interest is not in concealing information from competitors but from trading partners. We investigate trade-secret protection in such cases. Frequently, asymmetric information will lead to inefficient trade; at the same time, protecting private information might create incentives for socially desirable investments. We model this trade-off in a simple buyer-seller model and find that the optimal fine for violations of trade secrets is positive. In general, however, the welfare effects of increasing a fine are ambiguous. We discuss conditioning the legal protection on a minimum investment by the informed party to conceal the information and argue that this helps to apply trade-secret protection only when it increases welfare. This rationalizes important features of current legal practice. The Author 2009. Published by Oxford University Press on behalf of Yale University. All rights reserved.
