The FIW Research Centre International Economics and its partne rs kindly invite you to participate in the upcoming Vienna International Ec onomics Seminar (VIES) on the topic: “Dynamic Models\, New Gains from Tra de?” Abstract: Yes. We state closed-form expressions for steady state ga ins from trade that apply in a class of dynamic trade models that includes dynamic versions of the Krugman (1980)\, Melitz (2003)\, and customer capit al (e.g.\, Arkolakis\, 2010) models. The gains are a function of the domest ic trade share and the long-run elasticity of trade with respect to iceberg trade costs\, similar to Arkolakis\, Costinot\, and Rodríguez-Clare (2012 ). In a dynamic setting\, this long-run elasticity cannot be estimated in o ne step by relying on tariff variation as shifters of trade costs. Instead \, it can be recovered by combining two tariff elasticity estimates: the lo ng- and the short-run. Thus\, the short-run tariff elasticity indirectly en ters the formula for the steady state gains from trade. Our main substantiv e finding is that the gains from trade are large. They depend crucially on the short-run tariff elasticity\, and can be arbitrarily large even if the long-run tariff elasticity is high. Accounting for the transition path has a modest impact on the magnitude of the gains from trade\, relative to simp ly comparing steady states. Speaker: Christoph E. Boehm is an Assistant Pro fessor of Economics at the University of Texas at Austin. His research focu ses on business cycles\, stabilization policy\, and the international trans mission of shocks. Prior to coming to Austin he earned a PhD. in Economics from the University of Michigan\, was a Post-Doc at Princeton University an d was a Fulbright Scholar at Tufts University where he earned an MA in Econ omics. He also holds a Diploma in Business Management and Engineering from Dresden University of Technology. His research has been published in journa ls such as the Journal of Monetary Economics\, and the Review of Economics and Statistics.

The Vienna Int ernational Economics Seminar (VIES) is a joint initiative of CEU\, FIW Rese arch Centre International Economics\, Universität Wien\, WIFO\, wiiw\, and WU Vienna. It provides a forum for the presentation and discussion of cutt ing-edge academic research in the field of international economics. The sem inar is held at irregular intervals on Tuesdays from 17:45 to 19:15\, alter nating each semester between participating institutions. From October 2025 to January 2026\, the seminar will be hosted by the University of Vienna.
