The Benefits of Trade Secret Legal Protection: Evidence from Firms’ Cost Structure Decisions

We investigate whether better trade secret legal protection permits a firm to shift resources from protecting trade secrets to expanding its fixed operation capacity, thus reducing cost elasticity. We employ the staggered adoption of the Inevitable Disclosure Doctrine (IDD) by US state courts as a plausibly exogenous shock that improves trade secret legal protection. We find a reduction, on average, in cost elasticity in firms headquartered in the IDD recognition states relative to those in non-affected states. This change in cost structure is concentrated in firms with trade secrets. These results highlight that the optimal choice of fixed resources is affected by the extent of trade secret protection. Further, we find that firm value is higher for trade secret firms after the IDD adoption. Overall, our empirical evidence suggests that trade secret legal protection is beneficial for firms with trade secrets.
