This paper compares reward systems to intellectual property rights (patents and copyrights). Under a reward system, innovators are paid for innovations directly by government (possibly on the basis of sales), and innovations pass immediately into the public domain. Thus, reward systems engender...

In evaluating the effect of an R&D subsidy we need to know what the subsidized firm would have spent on R&D had it not received the subsidy. Using data on Israeli manufacturing firms in the 1990s we find evidence suggesting that the R&D subsidies granted by the Ministry of Industry and Trade...

A number of market failures have been associated with R&D investments and significant amounts of public money have been spent on programs to stimulate innovative activities. In this paper, we review some recent microeconomic studies evaluating effects of government sponsored commercial R&D. We...

Individuals involved in basic research, like other workers, respond to incentives. Funding agencies provide implicit incentives when they specify the rules by which awards are made. The following analysis is an exercise in understanding incentives at an applied level. Specific rules are examined...

We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation--in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model...

This paper surveys the econometric evidence on the effectiveness of fiscal incentives for R&D. We describe the effects of tax systems in OECD countries on the user cost of R&D - the current position, changes over time and across different firms in different countries. We describe and criticize...

Despite their magnitude and potential economic impact, federal R&D expenditures outside of research universities have been little scrutinized by economists. This paper examines whether the series of initiatives since 1980 that have sought to encourage the patenting and technology transfer at the...

Knowledge of how science is consumed in public domains is essential for a deeper understanding of the role of science in human society. While science is heavily supported by public funding, common depictions suggest that scientific research remains an isolated or 'ivory tower' activity, with...

The speed with which Covid-19 vaccines were developed and their high-performance underlines how much society depends on the pace of scientific research and how effective science can be. This is especially the case for vaccines based on the new designer mRNA technology. We draw on this...
