This study compares two alternative approaches to estimate parameters in gravity equations. We compare the traditional OLS approach applied to the log-linear form of the gravity model with the Poisson Quasi Maximum Likelihood (PQML) estimation procedure applied to the non-linear multiplicative...

Using a gravity-type explanation of international trade flows at the industry level, it is shown that the pattern of comparative advantage in terms of sectoral export/import ratios in bilateral trade can be explained by relative income and relative per capita income. Total income of a country is...

This study suggests another explanation of the "missing globalization puzzle" typically observed in the empirical gravity models. In contrast to the previous research that focused on aggregated trade flows, we employ the trade flows in manufacturing products broken down by 25 three-digit ISIC...

This note explores the relationship between the price elasticity of demand and the R&D intensity of the product. We introduce the concept of R&D intensity into a standard Dixit-Stiglitz/Krugmann-type setting. R&D activity is treated as a ficed cost of production. Within this framework, sectors...

Zum 1. Mai 2004 werden zehn weitere Volkswirtschaften der Europäischen Union beitreten. In den Verträgen ist die künftige Einführung des Euro vorgesehen, wenngleich hier kein genauer Terminplan besteht. Acht der Beitrittsländer liegen in Mittel- und Osteuropa: Estland, Lettland, Litauen,...

Die EU-Osterweiterung birgt auch für die Wirtschaft im Land Brandenburg zusätzliche Chancen und Risiken. Von allen Beitrittsländern ist Polen der größte Handelspartner Brandenburgs. Anhand des brandenburgischen Außenhandels wird untersucht, welche Potentiale sich der Wirtschaft des Landes...

This study analyzes the stability of the distance coefficient values over time in the generalized gravity equation of Bergstrand (1989) using both aggregate and disaggregated trade flows among 22 OECD countries recorded for the sample period covering 1970 until 2000. We estimate the gravity...
