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,...

With endogenous skills and given technology, labor market integration necessarily lowers welfare of the left-behind in a poor sending country, even if all agents face identical emigration probabilities. This is in sharp contrast to the case of exogenous skill supply.

In his seminal paper, Rose (2004) concluded from a gravity-type study of bilateral trade that the GATT/WTO does not play a strong role in encouraging trade. Rose looks at countries where the amount of trade was positive to start with (intensive margin). In this paper, we present a...

Many European countries restrict immigration from new EU member countries. The rationale is to avoid adverse wage and employment effects. We quantify these effects for Germany. Following Borjas (2003), we estimate a structural model of labor demand, based on elasticities of substitution between...

This paper characterizes analytically the optimal tariff of a large one-sector economy with monopolistic competition and firm heterogeneity in general equilibrium, thereby extending the small-country results of Demidova and Rodriguez-Clare (JIE, 2009) and the homogeneous firms framework of Gros...

Using rich linked employer-employee data for (West) Germany between 1996 and 2014, we analyze the most important drivers of the recent rise in German wage dispersion and pin down the relative contribution of plant and worker characteristics. Moreover, we separately investigate the drivers of...

Exploiting changes in the geography of economic integration in Europe, this paper uses detailed bilateral trade data for 50 sectors to carry out an econometric ex post evaluation of the trade cost effects of the United Kingdom’s various arrangements with the European Union. The analysis...

When two countries conclude a free trade agreement (FTA), they define rules of origin (RoOs) to determine whether a product is eligible for preferential treatment. RoOs exist to avoid that exports from third countries enter the FTA through the member with the lowest tariff (trade deflection)....

Climate research suggests that global warming will lead to more frequent and more extreme natural disasters. Most disasters are local events with effects on local economic activity. Hence, assessing their economic impacts with the help of econometric country-level analysis may lead to biased...

This paper uses Chinese customs data to investigate the trade effects of anti-dumping (AD) policies. Merging firm-level exports to firm-specific AD duties, we exploit differences across firms within products. This reduces endogeneity concerns which have plagued earlier research. Based on a...
