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...

Empirical research on the gravity model of international trade in the wake of Rose (2000) affirms that currency union formation doubles or triples trade. Currency unions could, however, also be established precisely because trade among their members was already high. In OLS estimation, this...

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...

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,...

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...

The Paper studies determinants of internal migration in Russia. Using panel data on gross region-to-region migration flows in 1992-99, we estimate the effect of economic, political and social factors. Although overall migration is rather low, it turns out that its intensity does depend on...
