We examine the role of spillover learning in shaping the value of exploratory versus incremental R&D. Using data from drug development, we show that novel drug candidates generate more knowledge spillovers than incremental ones. Despite being less likely to reach regulatory approval, they are...

We study the relationship between firm centralization and organizational reproduction in satellite locations. For decentralized firms, the ethnic compositions of inventors in satellite locations mostly resemble their host cities, with little link to the inventor composition of their parent...

We examine effective tax rates (ETRs) for 9,022 multinationals from 87 countries from 2006 to 2011. We find that, despite extensive investments in international tax avoidance, multinationals headquartered in Japan, the U.S., and some high-tax European countries continue to face substantially...

Operation Warp Speed (OWS) was a U.S. government-led program to accelerate the development, production, and administration of COVID-19 vaccines. The program cut the typical ten-year timeline needed to develop a new vaccine down to ten months and began vaccinating vulnerable populations within a...

This paper uses a large language model to develop an ex-ante measure of the commercial potential of scientific findings. In addition to validating the measure against the typical holdout sample, we validate it externally against 1.) the progression of scientific findings through a major...

Understanding factors affecting the direction of innovation is a central aim of research in the economics of innovation. Progress on this topic has been inhibited by difficulties in measuring distance and movement in knowledge space. We describe a methodology that infers the mapping of the...

Usually transportation/communication (t/c) considerations appear as only two in a long list of factors which determine headquarters location patterns. The research reported here singles out t/c considerations as the logical basis for headquarters location decisions. We ask: to what degree do...

Many employers link wages at the firm's establishments outside of the home region to the level at headquarters. Multinationals that anchor-to-the headquarters also transmit wage changes arising from shocks to minimum wages and exchange rates in the home country/state to their foreign...

The standard measures of flows and stocks of FDI view FDI as a financial flow and its accumulation as a stock, but most uses of FDI data require measures of employment, payrolls, capital inputs, and output from FDI. Judging by data for the United States, the flow and stock data provide rough...

Gains from productivity and knowledge transmission arising from the presence of foreign firms have received a good deal of empirical attention, but theoretical micro-foundations for this mechanism are limited. Here we develop a dynamic model in which foreign experts may train domestic workers...
