In the standard heterogeneous firm model of Hopenhayn (1992) and Melitz (2003), more efficient firms export and trade liberalization leads to higher average efficiency among firms. In data for Columbian plants 1981–1991, we see that the average level of productivity among exporters is...

Quantifying the gains from international trade is an area of research that has been widely studied using a variety of trade models. At the same time, it has been shown that non-homotheticities are useful for matching the systematic patterns of trade present in disaggregated trade data. We bring...

We measure the gains from a trade cost reduction in a model with dynamic accumulation of factors. We show that the tight link between import intensity and gains from trade that exists in static models breaks down along transition paths in dynamic models. When trade costs are reduced, the need to...

We develop a general equilibrium model with a detailed structure of government expenditures and revenues, calibrate it to the Greek and German economies, and use it to study the link between fiscal discipline and defaults. We show that even if the Greek government had entered the Great Recession...

We study the impact of trade on a country catching up to the industrial leader. We calibrate our dynamic, two-country model to Spain and UK from 1850 to 2000, accounting for the inter-war trade collapse (IWTC) and the subsequent catch up by Spain. In our model, the effects of trade disruptions...

The neoclassical growth model (NGM), which is widely used to study macroeconomic phenomena, has a constant labor share built in. However, several recent studies show that the labor share has been declining since at least the 1980s. This calls into question whether the NGM should still be used as...

Atkinson, Piketty, and Saez [2011] find a post-1979 surge in taxfiler top income shares in “English speaking countries” (surge countries) but not in “continental European countries and Japan” (no-surge countries). We find the puzzle that Comtrade import-to-GDP ratios and...

Applied general equilibrium (AGE) models, which feature multiple countries, multiple industries, and input-output linkages across industries, have been the dominant tool for evaluating the impact of trade reforms since the 1980s. We review how these models are used to perform policy analysis and...

Total Factor Productivity (TFP) growth in Canada between 2002 and 2014 has been only 0.16% per year. Although many developed countries have experienced a productivity slowdown since the beginning of the century, this figure is still substantially smaller than that of the U.S. We perform multiple...

We study a labor market where firm have private information about their ex-ante heterogeneous productivities and search is random. In this environment, a binding minimum wage can be efficiency-enhancing -- we show that setting it using a version of the Vickery-Clarke-Groves mechanism delivers...
