We use the 2018-2019 U.S. trade war to examine how supply chains adjustments to a tariff cost shock affect imports and exports. Using confidential firm-trade linked data, we show that the decline in imports of tariffed goods was driven by discontinuations of U.S. buyer-foreign supplier...

The U.S. opioid crisis is now driven by fentanyl, a powerful synthetic opioid that currently accounts for 90% of all opioid deaths. Fentanyl is smuggled from abroad, with little evidence on how this happens. We show that a substantial amount of fentanyl smuggling occurs via legal trade flows,...

During the decade since 1973, the U.S. economy has become increasingly interdependent with the newly industrializing countries (NICs) among the developing countries. These countries have had high investment ratios to GNP, financed mainly by domestic saving, but also partly by foreign borrowing....

We develop a new method of quantifying the impact of policy announcements on investment rates that makes use of stock market data. By estimating the effect of U.S.-China tariff announcements on aggregate returns and the differential returns of firms exposed to China, we identify their effect on...

International trade exposure affects job creation and destruction along the intensive margin (job flows due to expansions and contractions of firms' employment) as well as along the extensive margin (job flows due to births and deaths of firms). This paper uses 1992-2011 employment data from the...
