The gravity model of trade is utilized to assess the impact of disintegration on trade. The analysis is based on three recent disintegration episodes involving the former Soviet Union, Yugoslavia and Czechoslovakia. The results point to a very strong home bias around the time of disintegration,...

The “distance effect” measuring the elasticity of trade flows to distance has been to be rising since the early 1970s in a host of studies based on the gravity model, leading observers to call it the “distance puzzle”. We review the evidence and explanations. Using an extensive data set...

The demise of the CMEA trading system in 1991 and the shift to convertible currency settlements and world market prices was expected to bring about a severe contraction of intra-group trade, coupled with large imbalances in trade between Eastern Europe and the former Soviet Union. The observed...

This paper makes a tentative forecast of the impact on Spanish trade of the liberalization of economic transactions between the EU and the former communist countries of Central and Eastern Europe (CEECs), as envisaged in the Association Agreements aimed at the eventual enlargement of the EU to...

Conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity, especially international trade. Yet nothing is known empirically about these effects in large samples. We study the effects of war on bilateral trade for almost all...

The paper applies a gravity model to 1980-1996 annual non-fuel imports data for 58 countries to quantify the effects of recently created or revamped PTAs on trade. We modify the usual gravity equation to identify separate effects of PTAs on intra-bloc trade, members' total imports and their...

One feature of the European patent system that is heavily criticized nowadays is related to its complex fragmentation and the induced cost burden for applicants. Once a patent is granted by the EPO, the assignee must validate (and often translate) it and pay the renewal fees to keep it in force...

In this paper we test the well-known hypothesis of Obstfeld and Rogoff (2000) that trade costs are the key to explaining the so-called Feldstein-Horioka puzzle. Using a gravity framework in an intertemporal context, we provide strong support for the hypothesis and we reconcile our results with...

We assess the evolution of international banking integration at the light of gravity equations on banks’ bilateral consolidated foreign claims data. Our estimates on a panel of 14 reporting countries and their 186 partners between 1999 and 2012 reveal: 1) the forward march of banking...
