We examine the quantitative impact of policy-induced changes in innovative investment by firms on growth in aggregate productivity and output in a model that nests several of the canonical models in the literature. We isolate two statistics, the impact elasticity of aggregate productivity growth...

Technological progress is typically a result of trial-and-error research by competing firms. While some research paths lead to the innovation sought, others result in dead ends. Because firms benefit from their competitors working in the wrong direction, they do not reveal their dead-end...

This paper examines argues that while two distinct perspectives characterize the foundations of the public funding of research - filling a selection gap and solving a disclosure problem - in fact both the selection choices of public funders and their criteria for disclosure and commercialization...

The standard view of U.S. technological history is that the locus of invention shifted during the early twentieth century to large firms whose in-house research laboratories were superior sites for advancing the complex technologies of the second industrial revolution. In recent years this view...

We simultaneously assess the contributions to productivity of three sources of research and development spillovers: geographic, technology and product-market proximity. To do this, we construct a new measure of geographic proximity that is based on the distribution of a firm's inventor locations...

This paper is a first step toward closing the analytical gap in the extensive literature on the results of interactions between public and private R&D expenditures, and their joint effects on the economy. Econometric studies in this area report a plethora of sometimes confusing and frequently...

The goal of this paper is to provide an overview of R&D policy in Israel, and critically examine the policies currently in place as well as proposals to change them. We review in Part I the various programs of the Office of the Chief Scientist (OCS) of the Ministry of Industry and Trade in...

This paper introduces a general equilibrium model of endogenous technical change through basic and applied research. Basic research differs from applied research in the nature and the magnitude of the generated spillovers. We propose a novel way of empirically identifying these spillovers and...

Support for Ramp;D subsidies relies on empirical evidence that Ramp;D quot;spills overquot; between firms. But firm performance is affected by two countervailing Ramp;D spillovers: positive effects from technology spillovers and negative business stealing effects from Ramp;D by product market...

Research Joint Ventures (RJVs) are projects that combine the research resources of different firms. A sample of RJVs supported by the U.S. Advanced Technology Program shows that the projects yield revenues that are far less than costs. Related to this point, the RJVs are subject to...
