Imperfect Property Rights, James Bessen Oct 2009

Imperfect Property Rights, James Bessen

Faculty Scholarship

In theory, property rights allow markets to achieve Pareto optimal allocations. But the literature on contracting largely ignores what happens when property rights are imperfectly defined and enforced. Although some models include weak enforcement or poorly defined rights or "anticommons," this paper develops a general model that includes all of these possibilities. I find that combinations matter: Policy prescriptions to remedy individual imperfections are sometimes inappropriate under other conditions. For example, stronger penalties for violating rights can decrease Pareto efficiency, contrary to a common view. Also, collective rights organizations, such as patent pools, sometimes worsen problems of overlapping claims.


Evaluating The Economic Performance Of Property Systems, James Bessen Jun 2009

Evaluating The Economic Performance Of Property Systems, James Bessen

Faculty Scholarship

How should the economic performance of property systems be evaluated? Benefit-cost analysis is widely used to evaluate non-market based regulation when prices are not available. Market prices provide better information for property systems, but market prices are not necessarily socially optimal when property rights are imperfect. This paper discusses two practical approaches to evaluating the performance of property systems, one based on an analysis of institutional performance, the other based on measuring incentives. As an illustration, I show how these approaches might be used to evaluate the US patent system.
