We estimate differences in innovation behavior between foreign versus U.S.-born entrepreneurs in high-tech industries. Our data come from the Annual Survey of Entrepreneurs, a random sample of firms with detailed information on owner characteristics and innovation activities. We find uniformly...

We present a theoretical model of startup signaling with multiple signals and potential differences in external investor preferences. For a novel sample of technology incubator startups, we empirically examine the use of patents and founder, friends, and family (FFF) money as such signals,...

This paper analyzes the effects of top nanoscale scientists on industry entry in the comparative context of 5 major areas of science and technology, extending the concept of star scientist to all areas of science and technology. The results for nanotechnology are replicated using the...

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...

Urban China's high levels of ambient air pollution both lowers quality of life and raises mortality risk. China's wealthy have the purchasing power to purchase private products such as portable room air filters that allows them to offset some of the pollution exposure risk. Using a unique data...

We revisit the effect of the “Eco-Patent Commons” (EcoPC) on the diffusion of patented environmentally friendly technologies following its discontinuation in 2016, using both participant survey and data analytic evidence. Established in January 2008 by several large multinational companies,...

The U.S. tax code provides a number of subsidies for low-carbon technologies. I discuss the difficulties of achieving key policy goals with subsidies as opposed to using taxes to raise the price of pollution-related activities. In particular, subsidies lower the cost of energy (on average)...
