The economic value of upstream research outcomes has raised increasing attention. Not only are these outcomes central to the development of many innovations, but they are also the object of many transactions in technology. This note discusses a few representative papers that try to better...

One of the most conspicuous features of mergers is that they come in waves that are correlated with increases in share prices and price/earnings ratios. We use a natural way to discriminate between pure stock market influences on firm decisions and other influences by examining merger patterns...

I examine the efficiency of patent pooling in a setting that allows for the interplay between the standards process, in which owners of essential intellectual property (IP) develop a new product, and the subsequent pooling decision, in which IP prices are coordinated. If one of the IP owners is...

We discuss recent research on the growth of chains in the retail and service sectors, and point out the role of franchising in these industries, using new data on franchising collected by the U.S. Census Bureau. We then discuss several topics that one can analyze with data on chains, and...

Knowledge spillovers are widely thought to be important for innovative activity, yet theory is ambiguous about the sign of the relationship. Assuming that knowledge spillovers are more easily exploited where intellectual property rights are weakly enforced, this paper uses country–industry...

We study the effect of different levels of information on two-sided platform profits—under monopoly and competition. One side (developers) is always informed about all prices and therefore forms responsive expectations. In contrast, we allow the other side (users) to be uninformed about prices...

I revisit the issue of aftermarkets by developing an infinite period model with overlapping consumers. If the aftermarket is characterized by constant returns to scale, then social surplus and consumer surplus are invariant with respect to aftermarket power. Under increasing returns to scale,...

Clements (2004) makes the following two claims: (i) unlike direct network effects, increases in the size of the market do not, in the case of indirect network effects, make standardization more likely, but (ii) indirect network effects are associated with excessive standardization. We show in...

We analyze the potential trade-off between product variety and consumer information and the implications this trade-off has for product quality. We introduce a simple information accumulation process in a horizontal differentiation model with unobservable quality. As the number of brands...

This paper compares the equilibrium outcomes in search markets with and without referrals. Although it seems clear that consumers would benefit from referrals, it is not at all clear whether firms would unilaterally provide information about competing offers since such information could...
