We quantify the economic impact of a potential secession of Catalonia from Spain. Using a novel dataset of trade flows between 17 Spanish sub-national regions and 142 countries, we estimate effects of different levels of borders on trade flows and uncover heterogeneity in country-to-country,...

Proper measurement and aggregation of trade costs is of paramount importance for sound academic and policy analysis of the determinants - particularly those of policy - of economic outcomes. The international trade profession has witnessed significant new developments, both on the theoretical...

We propose a simple method to identify the effects of unilateral and non-discriminatory trade policies on bilateral trade within a theoretically-consistent empirical gravity model. Specifically, we argue that structural gravity estimations should be performed with data that include not only...

In view of the deferred start of negotiations for the modernization of the Customs Union between the EU and Turkey (CU-EUT), we look back and analyse the ex post trade consequences of the CU-EUT. Employing up-to-date econometric best practices for regional integration agreements, we quantify...

Carbon tariffs are one prominently discussed environmental policy. The proponents stress the carbon tariffs' ability to mitigate the potential negative effect of environmental-friendly production on competitiveness, to avoid carbon leakage and to reduce world carbon emissions. We analyze the...

Unilateral climate policy suffers from carbon leakage, i.e. the (partial) offset of the initial emission reduction by increases in other countries. Different than most typically discussed climate policies, degrowth not only aims at reducing the fossil fuel use in an economy, but rather at a...

We quantify the economic impact of a potential secession of Catalonia from Spain. Using a novel dataset of trade flows between 17 Spanish sub-national regions and 142 countries, we estimate effects of different levels of borders on trade flows and uncover heterogeneity in country-to-country,...

Recent work by Anderson and van Wincoop (2003) establishes an empirical modeling strategy which takes full account of the structural, non-(log-)linear impact of trade barriers on trade in new trade theory models. Structural new trade theory models have never been used to evaluate and quantify...

Carbon tariffs are one prominently discussed climate policy. The proponents stress the carbon tariffs’ ability to restore competitiveness, avoid carbon leakage, and reduce world carbon emissions. We analyze the effects of carbon tariffs on trade, welfare, and carbon emissions in a structural...
