We present an original modeling tool that can be used to study the social mechanisms by which individual software developers’ efforts are allocated within large and complex open source projects. The dynamical agent-based model is first described analytically in a deterministic discrete choice...

This paper analyzes the requirements for a social welfare-optimized transition path toward a carbon-free economy, focusing particularly on the role of R&D and other technological measures to achieve timely supply-side transformations in the global production regime that will avert catastrophic...

The scientific legacy of Zvi Griliches' contribution to the economic analysis of the diffusion of technological innovations is the subject of this paper. It begins with an examination of the relationship between Griliches' pioneering empirical work on the introduction and adoption of hybrid corn...

Early contributions to the academic literature on free/libre and open source software (F/LOSS) movements have been directed primarily at identifying the motivations that account for the sustained and often intensive involvement of many people in this non-contractual and unremunerated productive...

This paper reflects on the relevance of “systems-theoretic” approaches to the interdependent policy issues relating to the dynamics of science, technology and innovation and their relationship to economic growth. Considering the approach that characterizes much of the current economics...

A new generation of information and communication infrastructures, including advanced Internet computing and Grid technologies, promises to enable more direct and shared access to more widely distributed computing resources than was previously possible. Scientific and technological...

The research reported here gives priority to understanding the inter-temporal resource allocation requirements of a program of technological changes that could halt global warming by completing the transition to a “green” (zero net CO2- emission) production regime within the possibly brief...

The first version of this paper was presented to the Conference on R&D, Education and Productivity, held in Memory of Zvi Griliches (1930 –1999) on 25-27th, August 2003 at Carr? des Sciences, Ministère de la Recherche, Paris, France. Gabriel Goddard furnished characteristically swift and...

There are three analytically distinct layers of the phenomenon that has been labeled “the anticommons” and indicted as a potential impediment to innovation resulting from patenting and enforcement of IPR obtained on academic research results. This paper distinguishes among “search...
