We survey the economic literature, both theoretical and empirical, on the choice of intellectual property protection by firms. Our focus is on the tradeoffs between using patents and disclosing versus the use of secrecy, although we also look briefly at the use of other means of formal...

Global climate change mitigation will require the development and diffusion of a large number and variety of new technologies. How will patent protection affect this process? In this paper we first review the evidence on the role of patents for innovation and international technology transfer in...

A frequently debated question is whether the use of intellectual property (IP) protection benefits the residents of low and middle income countries. We contribute to this debate with an analysis of the use of patents and trademarks by firms in Chile over the decade 1995-2005 as the then...

The debate between the North and the South about the enforcement of intellectual property rights in the South is examined within a dynamic general equilibrium framework in which the North innovates new products and the South imitates them. A welfare evaluation of a policy of tighter intellectual...

This paper provides novel empirical evidence on the private value of patents and Ramp;D in European firms during the period 1991-2004. We explore the relationship between firm's stock market value, patents, and quot;qualityquot;-weighted patents issued by the European Patent Office (EPO) and the...

We study the production of knowledge when many researchers or inventors are involved, in a setting where tensions can arise between individual public and private contributions. We first show that without some kind of coordination, production of the public knowledge good (science or research...

The evidence for the United States points to balanced growth despite falling investment-good prices and an elasticity of substitution between capital and labor less than one. This is inconsistent with the Uzawa Growth Theorem. We extend Uzawa's theorem to show that the introduction of human...

Evaluations of government Technology Development Funds (TDF) in Argentina, Brazil, Chile and Panama are surveyed. All the evaluations were done at the recipient (firm) level using data from innovation surveys, industrial surveys, and administrative records of the granting units, together with...

This paper makes the case that purposive, profit-seeking investments in knowledge play a critical role in the long-run growth process. First, we review the implications of neoclassical growth theory and the more recent theories of 'endogenous growth'. Then we discuss the empirical evidence that...

We analyze the effect of patent thickets on entry into technology areas by firms in the UK. We present a model that describes incentives to enter technology areas characterized by varying technological opportunity, complexity, and the potential for hold-up due to the presence of patent thickets....
