This article develops a dual general equilibrium model to analyze the effects of intra-industry trade in both intermediate goods and final goods on the productivity in the final good production. Intra-industry trade in intermediate goods determines an increase in the number of intermediate good...

Fixed point theorems are the standard tool used to prove the existence of equilibria in mathematical economics. This paper shows how to prove a slight generalization of Brouwer's and Kakutani's fixed point theorems using the familiar techniques of drawing and shifting curves in the plane and is,...

Die Außenhandelsverflechtungen Sachsens haben in den letzten Jahren stetig zugenommen. Werden Güter aus der gleichen Produktgruppe sowohl im- als auch exportiert, wird von intraindustriellem Handel gesprochen. Stammen die im- bzw. exportierten Güter hingegen aus unterschiedlichen...

A simple model of offshoring, which depicts offshoring as ‘shadow migration,’ permits straightforward derivation of necessary and sufficient conditions for the effects on wages, prices, production and trade. We show that offshoring requires modification of the four classic international...

We examine an export game where two firms (home and foreign), located in two different countries, produce vertically differentiated products. The foreign firm is the most efficient in terms of R&D costs of quality development and the foreign country is relatively larger and endowed with a...
