Tariffs and Goods-Market Search Frictions
We study tariffs in a general equilibrium dynamic model with search frictions between heterogeneous exporting producers and importing retailers. We show the model has a unique equilibrium and analytically characterize home unilateral import tariffs that maximize welfare given a passive foreign country. Search frictions add two terms to the standard optimal tariff expression: One lowers tariffs when contact rates are low; another when private export costs exceed social opportunity costs. Search frictions also introduce new incentives to subsidize imports due to market thickness effects. We ...

The Dollar in the U.S. International Transactions (USIT) Model
The dollar's 20 percent climb against a broad index of foreign currencies since the middle of 2014 has led to an increased focus on how dollar fluctuations affect the U.S. economy. This note provides further detail on the structure and estimation of the trade block of the USIT model. In the context of the model, we present the estimated effect of a 10 percent dollar appreciation on U.S. trade flows and trade prices. We conclude with an assessment of the model's performance since the dollar began its steep appreciation in the summer of 2014.

Tariffs and Goods-Market Search Frictions
We study uniform tariffs in a general equilibrium dynamic model with search frictions between heterogeneous exporting producers and importing retailers. We analytically characterize unilateral import tariffs that maximize domestic welfare. Search frictions lower these tariffs because of market thickness effects, which reinforce aggregate production nonconvexities. A calibration using 2016 U.S. and Chinese data suggests that optimal U.S. unilateral and Nash equilibrium tariffs with baseline search frictions are 10 ppt. below those in a model with reduced search frictions. Changes in welfare in ...

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 ...

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 ...

Seasonal Unemployment Rate Differences by Race, Ethnicity, and Gender
The labor market experiences of Americans differ by race, ethnicity, and gender. For example, between 1977 and 2019, the monthly standard deviation (volatility) of the unemployment rate for Black workers was 3.2 percent, substantially higher than the 1.5 percent experienced by their white counterparts.
