Working Paper
Better Bunching, Nicer Notching
We study the bunching identification strategy for an elasticity parameter that summarizes agents' response to changes in slope (kink) or intercept (notch) of a schedule of incentives. A notch identifies the elasticity but a kink does not, when the distribution of agents is fully flexible. We propose new non-parametric and semi-parametric identification assumptions on the distribution of agents that are weaker than assumptions currently made in the literature. We revisit the original empirical application of the bunching estimator and find that our weaker identification assumptions result in ...

Goods-Market Frictions and International Trade
We add goods-market frictions to a general equilibrium dynamic model with heterogeneous exporting producers and identical importing retailers. Our tractable framework leads to endogenously unmatched producers, which attenuate welfare responses to foreign shocks but increase the trade elasticity relative to a model without search costs. Search frictions are quantitatively important in our calibration, attenuating welfare responses to tariffs by 40 percent and increasing the trade elasticity by 50 percent. Eliminating search costs raises welfare by 1 percent and increasing them by only a few ...

Do oil futures prices help predict future oil prices?
The price of oil has risen by about 60% since mid-2004 and by more than 40% since the beginning of 2005. Though the U.S. economy has apparently absorbed this supply shock well so far, the path of future oil prices remains a concern for monetary policymakers. Higher oil prices can damp demand, as consumers and firms spend more of their budgets on oil-related products and less on other goods and services. Furthermore, if higher oil prices are passed through to a significant extent to other goods and services and ultimately wages, inflationary pressures can build. ; Is the price of oil likely to ...

Goods-Market Frictions and International Trade
We present a tractable framework that embeds goods-market frictions in a general equilibrium dynamic model with heterogeneous exporters and identical importers. These frictions arise because it takes time and expense for exporters and importers to meet. We show that search frictions lead to an endogenous fraction of unmatched exporters, alter the gains from trade, endogenize entry costs, and imply that the competitive equilibrium does not generally result in the socially optimal number of searching firms. Finally, ignoring search frictions results in biased estimates of the effect of tariffs ...

The Great Recession and a Missing Generation of Exporters
The collapse of international trade surrounding the Great Recession has garnered significant attention. This paper studies firm entry and exit in foreign markets and their role in the post-recession recovery of U.S. exports using confidential microdata from the U.S. Census Bureau. We find that incumbent exporters account for the vast majority of the decline in export volumes during the crisis. The recession also induced a missing generation of exporters, with large increases in exits and a substantial decline in entries into foreign markets. New exporters during these years tended to have ...

Discussion Paper
The Great Recession and a Missing Generation of Exporters
While the large collapse in aggregate international trade volumes during the Great Recession has been widely studied in the literature, the recovery is much less well understood. Indeed, by 2014 U.S. foreign sales were still below their historical post-recession level. In this note, we summarize the results of Lincoln, McCallum, and Siemer (2019), which considers how much of a role a "missing generation of exporters" played in explaining the relatively slow growth of foreign sales after the financial crisis.
Working Paper
The Rise of Exporting By U.S. Firms
Although a great deal of ink has been spilled over the consequences of globalization, we do not yet fully understand the causes of increased worldwide trade. Using confidential microdata from the U.S. Census, we document widespread entry into countries abroad by U.S. firms from 1987 to 2006. We show that this extensive margin growth is unlikely to have been due to significant declines in entry costs. We instead find evidence of large roles for the development of the internet, trade agreements, and foreign income growth in driving these trends.

Bunching Estimation of Elasticities Using Stata
A continuous distribution of agents that face a piecewise-linear schedule of incentives results in a distribution of responses with mass points located where the slope (kink) or intercept (notch) of the schedule changes. Bunching methods use these mass points to estimate an elasticity parameter, which summarizes agents' responses to incentives. This article introduces the command bunching, which implements new non-parametric and semi-parametric identification methods for estimating elasticities developed by Bertanha et al. (2021). These methods rely on weaker assumptions than currently made ...
