We show that in a two-sector economy with heterogeneous capital subsidies and monopoly power, primal and dual measures of TFP growth can diverge from each other as well as from true technology. These distortions give rise to dynamic reallocation effects that imply technology growth needs to be...

Global trade fell 30 percent relative to GDP during the Great Recession of 2008-2009. Did this collapse result from factors impeding international transactions or did it simply reflect the greater severity of the recession in highly traded sectors? We answer this question with detailed...

We derive aggregate growth-accounting implications for a two-sector economy with heterogeneous capital subsidies and monopoly power. In this economy, measures of total factor productivity (TFP) growth in terms of quantities (the primal) and real factor prices (the dual) can diverge from each...

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 Argentine crisis. Though imports collapsed by 70 percent from 2000-2002, the entry and exit of firms or products at the country level played a small role. The within-firm churning of imported inputs, however, played a...

The stability of the labor share of income is a key foundation in macroeconomic models. We document, however, that the global labor share has significantly declined since the early 1980s, with the decline occurring within the large majority of countries and industries. We show that the decrease...

The ratio of global trade to GDP declined by nearly 30 percent during the global recession of 2008-2009. This large drop in international trade has generated significant attention and concern. Did the decline simply reflect the severity of the recession for traded goods industries? Or...

Global trade fell 20 percent relative to world GDP during the global recession of 2008-2009. We develop a dynamic multi-country general equilibrium model of international trade to investigate the sources of this collapse. Our framework provides a complete accounting for what happened to...

The World Trade Organization forecasts that the volume of global trade will in 2009 exhibit its biggest contraction since World War II. This large drop in international trade is generating significant attention and concern. Given the severity of the current global recession, is international...

Episodes of large crises such as the Mexican crisis in 1994-1995, the East Asian crisis in 1997-1998, and the Argentine crisis in 2001-2002 are associated with large adjustments in trade flows. The dollar value of imports in Argentina, for instance, dropped by 80 percent between 2000 and 2002. A...
