We propose a stylized monopolistic competition model of international trade where firms differ with respect to the expected economic lifetime of their innovations. Upon entry, they receive a commonly observed signal which is updated over time. Jointly with partial irreversibility of investment,...

This article unifies two approaches for identifying the welfare and wage effects of immigration, one emphasizing the immigration surplus, the other stressing a potential welfare loss due to a terms-of-trade effect. We decompose the native welfare effect into a standard complementarity effect,...

World trade evolves at two margins. Where a bilateral trading relationship already exists it may increase through time (intensive margin). But trade may also increase if a trading bilateral relationship is newly established between countries that have not traded with each other in the past...

Since July 2013, the EU and the US have been negotiating a preferential trade agreement (PTA), the Transatlantic Trade and Investment Partnership (TTIP). We use a multi-country, multi-industry Ricardian trade model with national and international input-output linkages to quantify its potential...

The proposed Transatlantic Trade and Investment Partnership (TTIP) between the European Union and the United States of America would be the largest preferential trade agreement in the world. Encompassing almost half of world GDP, it will have strong economic effects on Germany. In this paper, we...

This letter uses an augmented gravity model to revisit the effect of similarity in income distributions on bilateral trade flows. We document a robust new empirical regularity: while differences in average incomes between two countries increase trade, differences in income dispersion reduce it....
