Heterogeneous firms and import quality: evidence from transaction-level prices
A key emerging insight in international economics is that the scope for quality differentiation can help to explain patterns in export prices at the level of products or firms. In this paper, a unified theoretical framework of firm heterogeneity in cost and quality is brought to bear on an expansive data set of U.S. import transaction prices collected by the Bureau of Labor Statistics (BLS). The higher moments of the price distribution are used to identify the scope for quality differentiation at the detailed product level; highly differentiated products account for about half of U.S. import ...

Will the United States Benefit from the Trans-Pacific Partnership?
U.S. involvement in what could be one of the world?s largest free trade agreements, the Trans-Pacific Partnership (TPP), has garnered a lot of attention, especially since the entry of Japan into negotiations last year. The proposed free trade agreement (FTA) encompasses twelve countries, which combined account for 45 percent of U.S. exports and 37 percent of U.S. imports. This broad coverage of U.S. trade seems to suggest large potential gains for the U.S. from the agreement. However, three quarters of this trade is already within the U.S. free trade agreement with Canada and Mexico (the ...

Offshoring bias in U.S. manufacturing: implications for productivity and value added
The rapid growth of offshoring has sparked a contentious debate over its impact on the U.S. manufacturing sector, which has recorded steep employment declines yet strong output growth--a fact reconciled by the notable gains in manufacturing productivity. We maintain, however, that the dramatic acceleration of imports from developing countries has imparted a significant bias to the official statistics. In particular, the price declines associated with the shift to low-cost foreign suppliers are generally not captured in input cost and import price indexes. Although cost savings are a primary ...

The hitchhiker’s guide to missing import price changes and pass-through
A large body of empirical work has found that exchange rate movements have only modest effects on inflation. However, the response of an import price index to exchange rate movements may be underestimated because some import price changes are missed when constructing the index. We investigate downward biases that arise when items experiencing a price change are especially likely to exit or to enter the index. We show that, in theoretical pricing models, entry and exit have different implications for the timing and size of these biases. Using Bureau of Labor Statistics microdata, we derive ...

The dynamics and differentiation of Latin American metal exports
This paper investigates the propensity of exporters in certain primary commodity sectors to innovate and then attempts to measure the associated gains. The high degree of differentiation in metal products is giving rise to the potential for vertical upgrading for a substantial portion of Latin American export sales. Estimation of a demand system for U.S. imports shows that relatively high-priced new varieties tend to gain market share, which suggests a correspondingly large increase in the relative quality of those varieties. Breaking down the types of metal products by order of their ...

Why is the U.S. share of world merchandise exports shrinking?
As the U.S. share of the world goods trade slips from its level in the 1980s and 1990s, concerns have arisen that the productivity of U.S. exporters has not been growing as fast as that of foreign firms selling similar products. However, an analysis of industry-level trade data suggests that two other factors explain much of the drop in export share: the changing composition of the products traded internationally and the diminished share of U.S. GDP in global output. Declining relative productivity may have played a role in the early 2000s, but it has not been a large factor across industries ...

Chinese exports and U.S. import prices
This paper develops a technique to decompose price distributions into contributions from markups and marginal cost. The estimators are then used as a laboratory to measure the relationship between increasing Chinese competition and the components of U.S. import prices. The estimates suggest that the intensification of Chinese exports in the 2000s corresponded to substantial changes in the distributions of both the markups and marginal cost of U.S. imports. The entry of a Chinese exporter in an industry corresponded to rest-of-world exporters shrinking their markup (lowering prices by up to 30 ...

Missing Import Price Changes and Low Exchange Rate Pass-Through
A large body of empirical work has found that exchange rate movements have only modest effects on inflation. However, the response of an import price index to exchange rate movements may be underestimated because some import price changes are missed when constructing the index. We investigate downward biases that arise when items experiencing a price change are especially likely to exit or to enter the index. We show that, in theoretical pricing models, entry and exit have different implications for the timing and size of these biases. Using Bureau of Labor Statistics (BLS) microdata, we ...

Going global: markups and product quality in the Chinese art market
We analyze two reasons for export prices to be different across markets ? namely, quality differentiation and variable markups ? and attempt to parse their relative importance and some of their underlying drivers. To overcome the substantial measurement issues in this task, we consider a particular industry as a special case: Chinese fine art. The simplicity of the supply-side of art vis--vis marginal cost and the wealth of data on its quality characteristics make it possible to separately identify the markup and quality components of international relative prices for Chinese artwork. Through ...

Crime, house prices, and inequality: the effect of UPPs in Rio
We use a recent policy experiment in Rio de Janeiro, the installation of permanent police stations in low-income communities (or favelas), to quantify the relationship between a reduction in crime and the change in the prices of nearby residential real estate. Using a novel data set of detailed property prices from an online classifieds website, we find that the new police stations (called UPPs) had a substantial effect on the trajectory of property values and certain crime statistics since the beginning of the program in late 2008. We also find that the extent of inequality among residential ...
