The world runs a trade surplus with itself: the reported values of exports exceed the reported values of imports. This is a logically impossible but well-known empirical fact. Less well-known is the fact that, in recent years, more than 80 percent of the global surplus is a trade surplus that...

Global imports subject to pre-shipment inspections (PSI) – a practice under which imports need to undergo a third party review process before shipment – shrank from 700 bn USD in 2010 to 87 bn in 2018. However, only little is known about the trade impact of such procedures, which on the one...

Do the U.S. have a current account surplus or a deficit with the EU? Since 2009, official sources disagree: The U.S. Department of Commerce claims a consistent U.S. surplus while Eurostat reports the opposite. International transactions are notoriously difficult to measure accurately, but the...

Decisions on public health measures to contain a pandemic are often based on parameters such as expected disease burden and additional mortality due to the pandemic. Both pandemics and non-pharmaceutical interventions to fight pandemics, however, produce economic, social, and medical costs. The...

Has the Kyoto Protocol induced carbon leakage? We conduct the first empirical ex-post evaluation of the Protocol. We derive a theoretical gravity equation for the CO2 content of trade, which accounts for intermediate inputs, both domestic and imported. The structure of our new panel database of...

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...
