Nitrogen oxides (NOX) emissions are creating significant air quality challenges in China’s megacities. Since Euro IV diesel buses equipped with selective catalyst reduction (SCR) systems failed to mitigate on-road NOX emissions as expected, real-world NOX emissions from newly introduced Euro V...

We study underwriting relationships in the floating rate debt market, where many issuers have a large number of offerings. We find that frequent issuers maintain close relationship with only three to five underwriters and pay significantly less underwriting fees than infrequent issuers. The...

This study provides evidence that shocks to the supply of trade finance have a causal effect on U.S. exports. The identification strategy exploits variation in the importance of banks as providers of letters of credit across countries. The larger a U.S. bank's share of the trade finance market...

Banks play a critical role in facilitating international trade by guaranteeing international payments and thereby reducing the risk of trade transactions. This paper uses banking data from the United States to document new empirical patterns regarding the use of letters of credit and similar...

Trade credit is the most important form of short-term finance for U.S. firms. In 2017, non-financial firms had about $3 trillion in trade credit outstanding equaling 20 percent of U.S. GDP. Why do sellers lend to their buyers in the presence of a well-developed financial sector? This paper...

This paper documents that an appreciation of the U.S. dollar is associated with a reduction in the supply of commercial and industrial loans by U.S. banks. An increase in the broad dollar index by 2.5 points (one standard deviation) reduces U.S. banks’ corporate loan originations by 10...

Cross border transactions are conducted using different payment contracts, the usage of which varies across countries and over time. In this paper I build a model that can explain this observation and study implications from this for international trade. In the model exporters optimally choose...

Financial institutions are increasingly linked internationally and engaged in cross-border operations. As a result, financial crises and potential bail-outs by governments have important international implications. Extending Allen and Gale (2000), we provide a model of international contagion...
