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...

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)....

Reportedly, firms often find it impossible to finance large and long-term projects despite positive net present values. Should governments step in and can their assistance be effective? This paper studies the case of public export credit guarantees in Germany. Covering the default risk of...

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...

We introduce search and matching unemployment into a model of trade with differentiated goods and heterogeneous firms. Countries may differ with respect to size, geographical location, and labor market institutions. Contrary to the literature, our single-sector perspective pays special attention...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

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 growth. Hence, assessing their economic impacts with the help of econometric country-level analysis may lead to biased...

Does trade openness cause higher GDP per capita? Since the seminal instrumental variables (IV) estimates of Frankel and Romer [F&R](1999) important doubts have surfaced. Is the correlation spurious and driven by omitted geographical and institutional variables? In this paper, we generalize F&R's...

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,...

Growth theory predicts that natural disasters should, on impact, lower GDP per capita. However, the empirical literature does not offer conclusive evidence. Most existing studies use disaster data drawn from damage records of insurance companies. We argue that this may lead to estimation bias as...
