Recently gravity trade models are applied to disaggregated trade data. Here many zeros arecharacteristic. In the presence of excess zeros usual Poisson Pseudo Maximum Likelihood(PPML) is still consistent, the variance covariance matrix however is invalid. Correcteconomic interpretation however...

This paper discusses the evolution of agricultural products comparativeadvantages in the state of Paraná foreign trade from 1989-2001, and verifies thepredominant type of trade for those products. The methodology is based on calculation of indicators of Revealed Comparative Advantage (Balassa,...

Die vorliegende Arbeit untersucht wissenschaftlich anhand eines theoretischen Modells, wie sich internationale Migration auf die Volkwirtschaft des Aufnahmelandes auswirkt – nicht nur im Rahmen der EU-Osterweiterung. Kapitel eins enthält neben einer Hinführung zum Thema einen allgemeinen...

The tradition of gravity models is in the analysis of trade flows with market size and geographic or economic distance as core variables. Both these variables can be important determinants of FDI, too. However, when such models are used to explain FDI, there can be differences in the mode of...

The recent proliferation of regional trade agreements (RTAs) has intensified the debate on their merits. A growing literature has addressed this policy debate, focusing on the welfare and trade effects of RTAs and their likely impacts on the multilateral trading system. Some view them as...

This paper examines whether exchange rate misalignment negatively affects agricultural trade, compared to other industry sectors. Nominal exchange rate misalignment is obtained from the percentage deviation of real exchange rates from their long-run equilibrium based on the theory of purchasing...
