Dear colleagues, The Department of Economics cordially invites you to the WU Economics Research Seminar on Wednesday, November 20th, with Joschka Wanner (University of Würzburg) on "New Trade Models, Same Old Emissions?" Abstract: This paper investigates the role of firm heterogeneity in environmentally extended new trade models, contrasting Eaton-Kortum and Melitz models to Armington and Krugman models. We show that when emissions per sales are constant across firms - a standard assumption in the literature - all four models predict identical emission responses. However, when emissions per quantity are constant across firms, this equivalence breaks. We propose a generalized framework that nests both assumptions. Calibrating the model with multiple industries and estimating the key elasticity between emission intensity and productivity using German firm-level data, we find that firm heterogeneity considerably raises emissions from trade liberalization.
