Individuals that consume different baskets of goods are differentially affected by relative price changes caused by international trade. We develop a methodology to measure the unequal gains from trade across consumers within countries. The approach requires data on aggregate expenditures and...

In 2018, the US launched a trade war with China, an abrupt departure from its historical leadership in integrating global markets. By late 2019, the US had tariffed roughly $350 billion of Chinese imports, and China had retaliated on $100 billion US exports. Economists have used a diversity of...

We study optimal dynamic lockdowns against Covid-19 within a commuting network. Our framework integrates canonical spatial epidemiology and trade models, and is applied to cities with varying initial viral spread: Seoul, Daegu and NYC-Metro. Spatial lockdowns achieve substantially smaller income...

We develop a unified framework to trace value added along global supply chains in the presence of foreign direct investment by decomposing either GDP based on forward linkages or final production based on backward linkages. The new framework accounts for the presence of foreign invested...

This paper investigates whether "natural" trade barriers of a country due to geography and other factors outside the country's control stimulate more or less policy barriers such as tariffs. Our theory predicts that the politician's relative weight on private benefits over social welfare in a...

This paper offers a new interpretation of the connection between openness and good governance. Assuming that corruption and bad governance drive out international trade and investment more than domestic trade and investment, a naturally more open economy' as determined by its size and geography...

A puzzle in empirical international finance is the difficulty in finding a large and negative effect of exchange rate volatility on international trade. A common explanation is the availability of hedging instruments. This paper examines the empirical validity of this explanation using data on...

This paper examines the effect of corruption-induced uncertainty on foreign direct" investment. The measure of uncertainty is constructed based on unpublished individual survey" responses on levels of corruption in host countries. The result is striking. The effect is negative statistically...

The paper studies the effect of the market's perceived exchange rate volatility on bid-ask spreads. The anticipated volatility is extracted from currency options data. An increase in the perceived volatility is found to widen bid-ask spreads. The direction of the effect is consistent with an...

Deardorff [Journal of International Economics 36 (1994) 167-175] offers an intuitively appealing test for factor price equality (FPE). He demonstrates that FPE is impossible if the set (i.e., lens) of points defined by regional factor abundance vectors does not lie within the set of points...
