报告内容简介：
This paper proposes a novel instrumental variable to estimate the effect of in-person interactions on bilateral trade. Our identification strategy exploits variations in third-country connecting flight capacities driven by external travel demand in the global flight network to leverage exogenous variations in the air connectivity between two countries. Several findings stand out. First, air connectivity boosts trade between countries, but mostly for industries with a high reliance on relationship-specific investments. Second, trade in new products, relative to existing products, responds more positively to improved air travel links. Third, the trade-promoting effect of air connectivity appears to be stronger for country pairs with weaker online social network connections. Overall, our results quantify the positive role of in-person communications in reducing transaction costs associated with tacit knowledge. Our estimation approach also provides a useful tool for evaluating a range of social and economic impacts of a complex transport network.
