We consider a model in which an innovating monopolist of a technologically superior intermediate input must sell this product to final output producers. Prior research shows that, with complete information, the monopolist's optimal strategy will lead to complete adoption of this technologically...

In patent race models, firms' noncooperatively chosen research projects typically display too much correlation. But when there are multiple intellectual property rights protection instruments, we find that the paths chosen in an R&D race can move towards the social optimum.

The economics of geographical indications (GIs) is assessed within a vertical product differentiation framework that is consistent with the competitive structure of the agricultural sector with free entry/exit. It is assumed that certification costs are needed for GIs to serve as (collective)...

When jointness is caused by allocatable fixed factors, in the normal case the marginal cost of any output increases as any other output increases, the supply of any output decreases as any other output price increases, and an input price increase may cause the supply of some outputs to increase.

When some input decisions can be made after price is realized, separation between production and hedging decisions still holds only under limited circumstances. Under the assumption of a restricted profit function that is quadratic in price, the optimal futures hedge of a risk averse firm equals...

A quality certification standard in a competitive setting can improve welfare but may affect consumers and producers differently. In a competitive model with quality preferences of the vertical product differentiation type, we find that producers prefer a higher (lower) quality standard than...

The exclusivity conferred to inventors by intellectual property rights (IPRs) provide an ex ante incentive for innovation, but the resulting market power yields an ex post inefficiency (because it limits use of the innovation). Strong IPRs may also affect innovation by limiting access of...

I model a scoring situation that arises frequently during soccer matches. The Nash equilibrium solution is shown to be broadly consistent with the conventional wisdom of experts. Data on goals scored over an entire season in Italyï¾’s soccer league provide statistical support for a...
