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...

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...

Recently gravity trade models are applied to disaggregated trade data. Here manyzeros are characteristic. In the presence of excess zeros usual Poisson Pseudo MaximumLikelihood (PPML) is still consistent, the variance covariance matrix howeveris invalid. Correct economic interpretation however...

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 study analyzes the sensitivity of trade flows to trade barriers from gravity equations, using different econometric techniques recently highlighted in the literature. Specifically, we compare a benchmark OLS fixed effects specification a la Feenstra (2002) with three emerging estimation...

Italian wine firms are facing a significant reduction in wine consumption and increasing competition in international markets. In fact, markets are becoming increasingly liberalized and producers of non-EU countries adopt even more aggressive strategies to increase their competitiveness....
