The theoretical literature on the cumulative innovation process has emphasized the role of ex-ante licensing – namely, licensing agreements negotiated before the follow-on innovator has sunk its R&D investment – in mitigating the risk of hold-up of future innovations. In this paper, we...

In this paper we analyze how industrial property rights (IPRs), measured by patents granted, affect competition at the industry level, and their induced effects on firms’ innovation incentives. We use for that purpose a panel dataset of Spanish manufacturing firms for the period 1990-2006....

The rate of patenting in the U.S. has exploded in the last half of the 1990s. It is widely believed that the increase in patent grants is at least partly a result of the apparent decline in examination standards. There has been little exploration, however, of the theoretical prediction that a...

The optimal term of copyright has been a matter for extensive debate over the last decade. Using a simple model we characterise optimal term as a function of a few key parameters. We estimate this function using a combination of new and existing data on recordings and books and find an optimal...

The optimal level for copyright has been a matter for extensive debate over the last decade. This paper contributes several new results on this issue divided into two parts. In the first, a parsimonious theoretical model is used to prove several novel propositions about the optimal level of...

We analyze firms’ incentives to cluster in an industrial district to benefit from <p> reciprocal technology spillovers. A simple model of cumulative innovation is presented <p> where technology spillovers arise endogenously through labor mobility. It is <p> shown that firms’ incentives to cluster are...</p></p></p>

We analyze the initial intellectual property (IP) right of 4,703 start-up entrants in the US, distinguishing between trademark and patent applications. The results show that start-ups are more likely to file for a trademark instead of a patent when entering into more competitive market...

In this paper we try to present the main trends of evolution of the ICT sector. Its dynamics, supported by a constant technical progress in ICs, compounded with “non convexities” such as network effects and high sunk costs, may either lead to a Schumpeter Mark I or Schumpeter Mark II...

This paper investigates the choice of a licensing mechanism by the holder of a patent whose validity is uncertain. We provide sufficient conditions of a general nature under which the licensor prefers to use a per-unit royalty contract. In particular we show that this is the case for the holders...
