We use micro data collected at the border and at retailers to characterize the effects of recent changes in US trade policy -- particularly the tariffs placed on imports from China -- on importers, consumers, and exporters. We start by documenting that the tariffs were almost fully passed...

We document the behavior of trade prices during the Great Trade Collapse of 2008-2009 using transaction-level data from the U.S. Bureau of Labor Statistics. First, we find that differentiated manufactures exhibited marked stability in their trade prices during the large decline in their trade...

We explore the consequences of global capital market segmentation by currency for the optimal currency composition of borrowing by firms. Global bond portfolios are driven by the currency of denomination of assets as investors prefer to lend in their home currency or the international currency,...

The modern notion of an international currency involves use in areas of international finance and trade that extend well beyond central banks' coffers. In addition to their important roles as foreign exchange reserves, international currencies are most frequently used to denominate corporate and...

It is surprisingly difficult to find economic variables that strongly co-move with exchange rates, a phenomenon codified in a large literature on "exchange rate disconnect." We demonstrate that a variety of common proxies for global risk appetite, which did not co-move with exchange rates prior...

Over the last 15 years, the typical household has increasingly concentrated its spending on a few preferred products. However, this is not driven by "superstar" products capturing larger market shares. Instead, households increasingly purchase different products from each other. As a result,...

Evaluating the economic impact of "social distancing" measures taken to arrest the spread of COVID-19 raises a fundamental question about the modern economy: how many jobs can be performed at home? We classify the feasibility of working at home for all occupations and merge this classification...

Global firms finance themselves through foreign subsidiaries, often shell companies in tax havens, which obscures their nationality in aggregate statistics. We associate the universe of traded securities with their issuer's ultimate parent and restate bilateral investment positions to better...

We use a novel dataset of online prices of identical goods sold by four large global retailers in dozens of countries to study good-level real exchange rates and their aggregated behavior. First, in contrast to the prior literature, we demonstrate that the law of one price holds very well within...

We empirically characterize the mechanics of trade adjustment during the Argen- tine crisis using detailed transaction-level customs data covering the universe of import transactions during 1996-2008. Though imports collapsed by nearly 70 percent from 2000-2002, the entry and exit of firms or...
