We focus on downstream uses that combine multiple intellectual property rights and examine the effects of introducing an intellectual property clearinghouse that reduces transaction costs associated with licensing. We show that this causes equilibrium royalties to rise in some cases and may harm...

This paper reviews and compares patent pools and intellectual property clearinghouses as alternative systems for increasing the efficiency of access to intellectual property. These systems improve economic efficiency in downstream research and development by economizing on search and transaction...

Using data for 134 locations in New Zealand, we study the effects of crime and agglomeration on urban amenity. We find that crime has significant negative effects on the value of urban amenity, with elasticities of approximately ?0.06 for firms and ?0.09 for workers. To put this effect in...

This paper develops a model of simple 'reputation systems' that monitor and publish information about the behavior of sellers in a market with search frictions and asymmetric information. The reputations created by these systems influence the equilibrium search patterns of buyers and thus...

We examine the effects of third-party clearinghouses that license intellectual property on behalf of inventors when downstream uses of IP require licenses to multiple complementary innovations. We consider different simple clearinghouse royalty redistribution schemes, and different innovation...

We consider patent pool formation by owners of essential patents for differentiated standards that may be complements or substitutes in use. Pooling improves coordination in terms of royalty setting within a standard but provokes a strategic response from licensors in the competing standard. We...
