We present a simple model wherein a patents regime is inferior to a trade secrets system, meaning that when private returns from innovation under the two regimes are the same, society will be better off if the innovator chooses not to patent. In our model, trade secret licensing is envisaged and...

We present a model where an incumbent firm has a proprietary product whose technology consists of at least two components, one of which is patented while the other is kept secret. At the patent expiration date, an entrant firm will enter the market on the same technological footing as the...

Maurer and Scotchmer (2002) pointed out that patents may be inferior to other forms of intellectual property in that the independent invention is not a defence to infringement. The authors' analysis refers to situations in which there is an unlimited number of potential entrants by independent...

Different protection mechanisms may be employed at the same time when an innovation is comprised of separately protectable components. If patents and trade secrets can be mixed in protecting single innovations, a strengthening in patent breadth may induce a lower level of patenting, as...

A common argument against compulsory licensing of intellectual property maintains that it facilitates the entry of inefficient producers, which may reduce social welfare independently of any effects on R and D incentives. We study the issue in a model where the innovative firm, under the threat...

The relevance of scope economies is central in the unbundling of competitive tendering introduced for the assignment of franchised monopolies in LPT services, concerning either urban or intercity local transport.<BR> We present a number of different cost specifications. The separable quadratic and...

A growing number of Local Public Transport (LPT) companies diversify their production lines by providing a large set of services. We investigate the cost structure of a sample of LPT companies operating in Italy and assess the presence and the magnitude of scope economies. We split the whole...

The aim of this note is to study the optimal licensing of a non drastic cost reducing patented innovation, if the patent holder facing spillover is not only concerned with the optimal number of licenses, but also with their time distrbution. A simple three agents model, a patentee and two...
