The Political Economy of Intellectual Property Treaties

Intellectual property treaties have two main types of provisions: national treatment of foreign inventors, and harmonization of protections. I characterize the circumstances in which countries would want to treat foreign inventors the same as national inventors. I then argue that national treatment of foreign inventors leads to stronger intellectual property protection than is optimal, and that this effect is exacerbated when protections must be harmonized. However levels of public and private R&D spending will be lower than if each country took account of the uncompensated externalities that its R&D spending confers on other countries. The stronger protections engendered by attempts at harmonization are a partial remedy.

Affirmative Action in Hierarchies

There is considerable evidence that males are more prone to take risks than females. This difference has implications for rates of promotion in hierarchies where promotion is based on random signals of ability. I explore the promotion consequences of three types of performance standards: gender-blind standards, standards designed to promote agents of equal ability on average, and standards designed to promote equal numbers of both genders. These three objectives lead to different promotion standards, which highlights among other things that the goal of affirmative action is not well defined. Lower promotion standards for females can be necessary to ensure either equal abilities or equal numbers in the promoted populations.

Consumption Externalities, Rental Markets and Purchase Clubs.

A premise of general equilibrium theory is that private goods are rival. Nevertheless, many private goods are shared, e.g., through barter, through co-ownership, or simply because one person’s consumption affects another person’s wellbeing. We analyze consumption externalities from the perspective of club theory, and argue that, provided consumption externalities are limited in scope, they can be internalized through membership fees to groups. Our main applications are to rental markets and “purchase clubs” in which members share the goods that they have individually purchased.

Risk taking and gender in hierarchies

In a labor market hierarchy, promotions are affected by the noisiness of information about the candidates. I study the hypothesis that males are more risk taking than females, and its implications for rates of promotion and abilities of survivors. I define promotion hierarchies with and without memory, where memory means that promotion depends on the entire history of success. In both types of hierarchies, the surviving risk takers have lower average ability whenever they have a higher survival rate. Further, even if more risk takers than non risk takers are promoted in the beginning of the hierarchy, that will be reversed over time. The risk takers will eventually have a lower survival rate, but higher ability. As a consequence of these differences, the various requirements of employment law cannot simultaneously be satisfied. Further, if promotion standards are chosen to maximize profit, the standards will reflect gender in ways that are difficult to distinguish from discriminatory intent.Labor market hierarchy, promotion, discrimination, affirmative action, hierarchy, risk taking, gender bias

Intellectual Property: When Is It the Best Incentive System?

Our objective in this paper is to review what economists have said about incentive schemes to promote R&D, including intellectual property. While we focus on environments in which other forms of protection are not available, we note that other protections can obviate the need for any formal reward system. In Section II, we compare intellectual property to alternative incentive schemes. In Section III we review optimal design issues for intellectual property, especially the question of patent breadth, and in Section IV we turn to the special problems that arise when innovation is cumulative. In Section V, we summarize the arguments for and against intellectual property. We comment on whether the design recommendations of economists can actually be implemented, and argue that IP regimes should be designed so that the subject matter of each one has relatively homogeneous needs for protection.

Digital Rights Management and the Pricing of Digital Products

As it becomes cheaper to copy and share digital content, vendors are turning to technical protections such as encryption. We argue that if protection is nevertheless imperfect, this transition will generally lower the prices of content relative to perfect legal enforcement. However, the effect on prices depends on whether the content providers use independent protection standards or a shared one, and if shared, on the governance of the system. Even if a shared system permits content providers to set their prices independently, the equilibrium prices will depend on how the vendors share the costs. We show that demand-based cost sharing generally leads to higher prices than revenue-based cost sharing. Users, vendors and the antitrust authorities will typically have different views on what capabilities the DRM system should have. We argue that, when a DRM system is implemented as an industry standard, there is a potential for "collusion through technology."
