Dieser Beitrag soll einen Überblick und eine Systematik im Hinblick auf die aktuellen Beiträge zum Phänomen der Fragmentierung geben. Während man im Zusammenhang mit der Ausweitung des Nord-Süd-Handels von einer "horizontalen Globalisierung" spricht, gilt Fragmentierung als Ausdruck einer...

This paper studies a Cournot duopoly in international trade so that the firms are exposed to exchange rate risk. A hedging opportunity is introduced by a forward market where the foreign currency can be traded on. We investigate two settings: First we assume that hedging and output decisions are...

As NATO expands eastward, Russia has expressed growing concerns over what it sees as a threat to its national security. At the same time Russia is transitioning to a market economy, with the aim of becoming a free trade partner with the West. The question of concern to European nations is; how...

The business literature suggests that exporters either use trade intermediaries or own foreign sales representations. Standard trade models are silent about this choice. We develop a model where producers differ with respect to competitive advantage and where trade intermediaries arise...

In terms of convex analysis the revenue function of a country with a given factor endowment may be seen as the support function of the production possibility set. At the same time this revenue function is the so called convex-conjugate of the indicator function of the production possibility set....

In der Aussenhandelstheorie wird das Angebot und die Nachfrage mit Hilfe der Dualitaetstheorie abgebildet. Dabei wird auf nationaler Ebene das Problem der Erloesmaximierung untersucht, wobei die nationalen Faktorbestaende und die Produktionstechnologien der einzelnen Unternehmen gegeben sind....

Freeman (2006) suggested that auctioning immigration visas and redistributing the revenue to native residents in the host country would increase migration from low-income to high-income countries. The effect of the auctioning of immigration visas, in the Ricardian model from Findlay (1982), on...

The analysis of migration in Findlay (1982) is extended by adding external economies of scale to the Ricardian model as in Ethier (1982). With external economies, the larger country always gains from trade but the smaller country may lose from trade unless the external economies of scale are...

We develop a Heckscher-Ohlin-Ramsey model, combining dual techniqueswith classic geometric techniques fromtrade theory. This framework is used to explore the long-run generalequilibrium effects of regional integration(preferential trade agreements). Emphasis is placed on positivemechanics...

Division of labor models have become a standard analytical tool, along withcompetitive general equilibrium models (Ricardian, HOS, Ricardo-Viner), in public finance, trade, growth, development, and macroeconomics. Yet unlike the earlier models, specialization models lack a canonical...
