Trade Elasticities
Conventional aggregate trade elasticity estimates hardly vary across countries. We introduce an aggregate elasticity that is implied by theory: It is the value that equates the welfare gains from trade as implied by one‐ and multi‐sector versions of the model in Arkolakis et al. ( American Economic Review , 102 (2012):94–130). These estimates are predicated on sector‐level values for trade elasticites, which we provide at three‐digit levels for 2…
Pooling risk among countries
Elasticity Optimism
On average, estimates of trade elasticities are smaller in aggregate data than at sector level. This is an artifact of aggregation. Estimations performed on aggregate data constrain sector elasticities to homogeneity, which creates a heterogeneity bias. The paper shows such a bias exists in two prominent approaches used to estimate elasticities, which has meaningful consequences for the calibration of the trade elasticity in one-sector, aggregati…
Credit Supply and the Price of Housing
An exogenous expansion in mortgage credit has significant effects on house prices. This finding is established using US branching deregulations between 1994 and 2005 as instruments for credit. Credit increases for deregulated banks, but not in placebo samples. Such differential responses rule out demand-based explanations, and identify an exogenous credit supply shock. Because of geographic diver-sification, treated banks expand credit: housing d…
The Premature Deindustrialization of South Africa
Manufacturing activities are on the wane in Sub-Saharan Africa. With the relocation of many industries into Asia, the trend is widespread across the world economy. The USA and most of the European Union are also deindustrializing, but at higher levels of per capita GDP than Africa. Their economies tend to move into services. In contrast, the deindustrialization of Sub-Saharan Africa is often associated with the rising importance of extractive act…
The Financial Crisis
This article introduces a special section of the American Economic Journal: Macroeconomics, containing five papers presented during a conference in Paris in October 2011. The aim of the conference was to derive lessons from the financial crisis, for research on international macroeconomics and for policy. The article opens with a summary of the key mechanisms at play during the crisis. The question of the crisis transmission across borders is add…

Credit Supply and the Price of Housing
One TV, One Price
We study television prices across European countries and regions. Quality as measured by observable characteristics of televisions accounts for a large share of the international dispersion in prices. Rich economies tend to consume higher‐quality goods, but sizeable international price differentials exist even for identical televisions. The valuation of brands differs significantly across borders. EMU countries display lower price dispersion but …

Trade, Finance, Specialization, and Synchronization
I investigate the determinants of business cycle synchronization across regions. The linkages between trade in goods, financial openness, specialization, and business cycle synchronization are evaluated in the context of a system of simultaneous equations. The main results are as follows. (i) Specialization patterns have a sizable effect on business cycles. Most of this effect is independent of trade or financial policy, but directly reflects dif…
The Real Effects of Financial Integration
Competition, Globalization, and the Decline of Inflation
Stages of Diversification
This paper studies the evolution of sectoral concentration in relation to the level of per capita income. We show that various measures of sectoral concentration follow a U-shaped pattern across a wide variety of data sources: countries first diversify, in the sense that economic activity is spread more equally across sectors, but there exists, relatively late in the development process, a point at which they start specializing again. We discuss …
