Intellectual Property Rights and Efficient Firm Organization

I provide a justification of intellectual property rights as a source of static efficiency gains in manufacturing, rather than dynamic benefits from greater innovation. I develop a property-rights model of a supply relationship with two dimensions of non-contractible investment. In equilibrium, the first best is attained if and only if owner-ship of tangible and intangible assets is equally protected. If IP rights are weaker, the organization of the firm is distorted and efficiency declines: the final producer must either integrate her suppliers, which prompts a decline in their investment; or else risk their defection, which entails a waste of her expertise. My model predicts a greater prevalence of vertically integrated manufacturers where IP rights are weaker, and a switch from integration to outsourcing over the product cycle. Empirical evidence on the international supply chains of multinational companies bears out both predictions. As a normative implication, I find that IP rights should be strong but narrowly defined, to protect a business without holding up non-competing derivative innovations
