Somatic distance, or differences in physical appearance, proves to be extremely important in the gravity model of bilateral trade in conformity with results in other areas of economics and outside of it in the social sciences. This is also true quite independently of survey evidence about...

Monetäre Disziplin – Deutschland und das Europäische Währungssystem Dieser Aufsatz untersucht die Hypothese, daß alle Mitgliedsländer des Europäischen Währungssystems (EWS) außer Deutschland Nutzen aus diesem System ziehen, weil es ihnen monetäre Disziplin auferlegt. Die Hypothese...

The paper is devoted to an econometric analysis of learning foreign languages in all parts of the world. Our sample covers 193 countries and 13 important languages. Four factors significantly explain learning, two of which affect the broad decision to learn, while two concern as well the choice...

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 issue of whether constraints should be placed on fiscal policies when moving to European monetary union is examined in the context of the use of fiscal policy for macroeconomic stabilization purposes. Examples of shocks hitting French and German economies are considered: an appreciation of...
