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...

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...

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...

Fragmentation of the global value chain makes it difficult to assess the effects of trade liberalization on the global pattern of production. Gross bilateral trade ows no longer reveal a country’s or a sector’s value added contribution. Yet, it is value added that matters for employment and...

We use a unique case study to estimate the effect of withdrawing from a free trade agreement on international trade. Lately, the political opposition to international economic cooperation has been on the rise, but little is known about how the withdrawal from a trade agreement affects trade. We...

Gravity as both fact and theory is one of the great success stories of recent research on international trade, and has featured prominently in the policy debate over Brexit. We first review the facts, noting the overwhelming evidence that trade tends to fall with distance. We then introduce some...

The withdrawal of the United Kingdom from the European Union has had disruptive effects on international trade. As part of its ‘Global Britain’ strategy, in the wake of Brexit, the UK is pursuing a series of Free Trade Agreements with countries around the world, including Canada, Japan,...

Epidemiological models assume gravity-like interactions of individuals across space without microfoundations. We combine a simple epidemiological frame-work with a dynamic model of individual location choice. The model predicts that flows of people across space obey a structural gravity...

Modern quantitative theories of international trade rely on the probabilistic representation of technology and the assumption of the Law of Large Numbers (LLN), which ensures that when the number of traded goods goes to infinity, trade flows can be expressed via a deterministic gravity equation...

We develop a network trade model with country-sector level input-output linkages. It includes (1) domestic and global value chain linkages between all country-sectors, (2) direct as well as indirect shipments (via other sectors and countries) to a final destination, (3) value added rather than...
