We examine the effect of prizes on innovation using data on awards for technological development offered by the Royal Agricultural Society of England at annual competitions between 1839 and 1939. We find large effects of the prizes on competitive entry and we also detect an impact of the prizes...

This paper builds on the analysis in Akcigit et al. (2017) by using US patent and Census data to examine macro and micro-level aspects of the relationship between immigration and innovation. We construct a measure of foreign born expertise and show that technology areas where immigrant inventors...

This paper studies the effect of corporate and personal taxes on innovation in the United States over the twentieth century. We use three new datasets: a panel of the universe of inventors who patent since 1920; a dataset of the employment, location and patents of firms active in R&D since 1921; and a...

We find a negative relationship between bank distress and the level, quality and trajectory of firm-level innovation during the Great Depression, particularly for R&D firms operating in capital intensive industries. However, we also show that because a sufficient number of R&D intensive firms...

In 1931, during one of the worst economic crises in US history, Du Pont announced the discovery of an innovative rubber synthetic product - neoprene. Yet at the time of the announcement, Du Pont did not have any neoprene to sell. Manufacturing facilities were still being erected and production...

We examine the golden age of U.S. innovation by undertaking a major data collection exercise linking historical U.S. patents to state and county-level aggregates and matching inventors to Federal Censuses between 1880 and 1940. We identify a causal relationship between patented inventions and...
