ESTIMATION ISSUES IN SINGLE COMMODITY GRAVITY TRADE MODELS
Prehn, Soren; Brummer, Bernhard - 2011
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...

Auswirkungen der internationalen Migration auf die Bundesrepublik Deutschland. Theoretische und empirische Analysen vor dem Hintergrund der EU-Osterweiterung
Pflugbeil, Stephan Dirk - 2005
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...

What Gravity Models Can Tell Us about the Position of German FDI in Central and Eastern Europe
Borrmann, Christine; Jungnickel, Rolf; Keller, Dietmar - 2005
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...

Effects of Regional Trade Agreements on Trade in Agrifood Products: Evidence from Gravity Modeling Using Disaggregated Data
Sarker, Rakhal; Jayasinghe, Sampath - 2004
intraregional trade is growing within NAFTA and that NAFTA has displaced trade with the rest of the world. NAFTA has served to boost … trade significantly among its members rather than with the rest of the world. Countries participating in NAFTA have moved … toward a lower degree of relative openness in agrifood trade with the rest of the world. …

The sensitivity of trade flows to trade barriers
Raimondi, Valentina; Olper, Alessandro - 2009
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...

Analysis of Italian High Quality Wine Exports using the Gravity Model Approach
De Blasi, Giuseppe; Seccia, Antonio; Carlucci, Domenico; … - 2007
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....
