We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize the analysis of Arkolakis, Costinot and...

The proposed Transatlantic Trade and Investment Partnership (TTIP) is the most significant trade policy initiative since the Uruguay Round (1986 to 1994). It would create a free trade zone covering 45% of world GDP. However, critics dismiss the possible welfare gains as small compared to the...

Arkolakis, Costinot and Rodriguez-Clare (ACR, 2012) prove that, conditional on the change in openness, the welfare gains from foreign trade reforms are quantitatively identical across single-sector trade models with radically different micro-foundations. We generalize this result to domestic and...

We quantify the partial and general equilibrium effects of GATT/WTO membership on trade and welfare. Using an extensive database covering manufacturing trade for 186 countries over the period 1980-2016, we find that the average impact of GATT/WTO membership on trade among member countries is...

We build on the latest developments in the structural gravity literature to quantify the partial and general equilibrium effects of GATT/WTO membership on trade and welfare. Using an extensive database covering manufacturing trade for 186 countries over the period 1980-2016, we find that the...

Das ifo Institut hat im Auftrag des Bundesministeriums für Wirtschaft und Technologie die vorliegende Evaluierungsstudie zu den Dimensionen und Auswirkungen eines Freihandelsabkommen zwischen der EU und den USA durchgeführt. Die Studie zeigt, dass ein tiefgreifendes Handelsabkommen...
