What’s Driving the Recent Slump in U.S. imports?
The growth in U.S. imports of goods has been stubbornly low since the second quarter of 2015, with an average annual growth rate of 0.7 percent. Growth has been even weaker for non-oil imports, which have increased at an average annual rate of only 0.1 percent. This is in sharp contrast to the pattern in the five quarters preceding the second quarter of 2015, when real non-oil imports were growing at an annualized rate of 8 percent per quarter. The timing of the weakness in import growth is particularly puzzling in light of the strong U.S. dollar, which appreciated 12 percent in 2015, ...

The increasing importance of services expenditures and the dampening effect on global trade
Globalization, particularly through international trade in goods, has helped to foster the creation of tremendous amounts of wealth and prosperity across much of the globe while lifting sizable portions of the world’s population out of poverty. In particular, the latter half of the twentieth century delivered unprecedented rates of increased economic integration among many countries. Access to global markets supported the industrialization of emerging economies and opened up new markets for firms in wealthier countries. As a result of the expansion of international trade and competition, ...

Menu Costs, Trade Flows, and Exchange Rate Volatility
U.S. imports and exports respond little to exchange rate changes in the short run. Pricing behavior has long been thought central to explaining this response: if local prices do not respond to exchange rates, neither will trade flows. Sticky prices and strategic complementarities in price setting generate sluggish responses, and they are necessary to match newly available international micro price data. Using trade flow data, I test models capable of replicating these trade price data. Even with significant pricing frictions, the models still imply a trade response to exchange rates stronger ...

What's Driving the Recent Slump in U.S. Imports?
In this post, we explore what has been driving the recent slump in U.S. imports of non-oil goods.

Structural Change and Global Trade
Services, which are less traded than goods, rose from 58 percent of world expenditure in 1970 to 79 percent in 2015. In a trade model featuring nonhomothetic preferences and input-output linkages, we find that such structural change has restrained the growth in world trade to GDP by 16 percentage points over this period. This magnitude is similar to how much declining trade costs have boosted openness. Moreover, structural change dampens the measured gains from trade by incorporating endogenous responses of expenditure shares to the trade regime. Ongoing structural change implies declining ...

Structural Change and Global Trade
Services, which are less traded than goods, rose from 50 percent of world expenditure in 1970 to 80 percent in 2015. Such structural change restrained "openness"?the ratio of world trade to world GDP?over this period. We quantify this with a general equilibrium trade model featuring non-homothetic preferences and input-output linkages. Openness would have been 70 percent in 2015, 23 percentage points higher than the data, if expenditure patterns were unchanged from 1970. Structural change is critical for estimating the dynamics of trade barriers and welfare gains from trade. Ongoing ...

Structural Change and Global Trade
Services, which are less traded than goods, rose from 58 percent of world expenditure in 1970 to 79 percent in 2015. Using a Ricardian trade model incorporating endogenous structural change, we quantify how this substantial shift in consumption has affected trade. Without structural change, we find that the world trade to GDP ratio would be 15 percentage points higher by 2015, about half the boost delivered from declining trade costs. In addition, this structural change has lowered the global welfare gains from trade integration by almost 40 percent over the past four decades. Absent further ...

Bill of Lading Data in International Trade Research with an Application to the COVID-19 Pandemic
We evaluate high-frequency bill of lading data for its suitability in international trade research. These data offer many advantages over both other publicly accessible official trade data and confidential datasets, but they also have clear drawbacks. We provide a comprehensive overview for potential researchers to understand these strengths and weaknesses as these data become more widely available. Drawing on the strengths of the data, we analyze three aspects of trade during the COVID-19 pandemic. First, we show how the high-frequency data capture features of the within-month collapse ...

On the U.S. Firm and Establishment Size Distributions
This paper revisits the empirical evidence on the nature of firm and establishment size distributions in the United States using the Longitudinal Business Database (LBD), a confidential Census Bureau panel of all non-farm private firms and establishments with at least one employee. We establish five stylized facts that are relevant for the extent of granularity and the nature of growth in the U.S. economy: (1) with an estimated shape parameter significantly below 1, the best-fitting Pareto distribution substantially differs from Zipf's law for both firms and establishments; (2) a lognormal ...

Trade in Value-Added
As global production sharing expands, gross trade flows provide an increasingly misleading picture of the economic importance of trade.
