Extending the basic model of two-stage cumulative innovation with asymmetric information to include `experimentation' by second-stage rms, we nd that the costs of a strong (versus weak) intellectual property (IP) regime may be substantially increased. In addition, these costs increase as...

?We consider a cumulative innovation process in which a follow-on innovator invests in R&D activities that influence both the expected commercial value as well as the novelty of its innovation. When the second innovator investments are not servable,licensing of the first innovation never occurs...

An extensive empirical literature indicates that returns from innovation are appropriated primarily via mechanisms other than formal intellectual property rights -- and that `imitation' is itself a costly activity. However most theory assumes the pure nonrivalry of `ideas' with its implication...

This Essay demonstrates the strategic advantage of narrow patents and unprotected publication of R&D output. Broad patents might stifle follow-on improvements by deterring potential cumulative innovators, who fear being held up by the initial inventor at the ex post licensing stage. By opting...

We show that if patent protection and trade secrecy generate asymmetricmarket structure, an innovator may prefer patent protection than trade secrecy even ifthe diffusion probability is higher under the former but it increases marketconcentration by preventing some imitators...

The Bali Roadmap marks a milestone in the process of international consensus building, setting forth a multilateral legal framework to address climate change. Delegates at the UN Climate Change Conference in Bali (Dec. 3-15 2007) launched a two-year process with a comprehensive agenda and 2009...

What are the key factors that facilitate innovation and creativity? This chapter begins by challenging the traditional emphasis on IP rights as an incentive to innovate. While it is true, that IP rights provide for a much needed tool to protect creative ideas, we argue that a much more important...

In this second version of this working paper, Emile Loza discusses the need to conceptualize innovation as a market system and identifies some of the actors, types of capital, and legal infrastructure needed to accelerate the deployment of innovation and improve the sustainability of innovators....

It is now widely asserted that legal regimes that enforce contractual and other limitations on labor mobility deter technological innovation. First, recent empirical studies purport to show relationships between bans on enforcing noncompete agreements, increased employee movement, and increased...
