We identify strong cross-border property rights as a driver for the globalization of innovation. Using 67 million patents from over 100 patent offices, we construct novel measures of the three stages of innovation diffusion: adoption, sourcing, and collaboration. Exploiting staggered bilateral investment treaties (BITs) as shocks to cross-border property rights, we show that signatory countries increase technology adoption and sourcing from each other; they also increase R&D collaborations. The results are particularly strong for countries with weak domestic institutions and technologies with high imitation risks. Increases in R&D-related foreign investments explain most of the results.

Individualism has long been linked to economic growth. Using the COVID-19 pandemic, we show that such a culture can hamper the economy's response to crises, a period with heightened coordination frictions. Exploiting variation in U.S. counties' frontier experience, we show that more individualistic counties engage less in social distancing and charitable transfers and are less willing to receive COVID-19 vaccines. The effect of individualism is stronger where social distancing has higher externality and holds at the individual level when we exploit migrants for identification. Our results suggest that individualism can exacerbate collective action problems during economic downturns.
