Trade theories covering Preferential Trade Agreements (PTAs) are as diverse as the literature in search of their empirical support. To account for the model uncertainty that surrounds the validity of the competing PTA theories, we introduce Bayesian Model Averaging (BMA) to the PTA literature....

The inequality in pre-tax income increases in Norway in the 1990s, while the distribution of taxes is about unaltered. This means that tax progressivity has decreased in the period, as measured by summary indices of tax progressivity. This paper discusses to what extent this observed decrease in...

This paper provides new evidence on the wage gap between informal and formal salary workers in South Africa, Brazil and Mexico. We use rich datasets that allow us to define informality in a relatively comparable fashion across countries. We compute precise wage differentials by accounting for...

Welchen kausalen Effekt erfahren Freiberufler durch eine freiwillige Berufsverbandsmitgliedschaft auf ihr Erwerbseinkommen? Diese Frage soll durch die Schätzung von Fixed-Effects-Modellen für Männer und Frauen im Rahmen einer mikroökonometrischen Evaluation mit Daten des Sozio-oekonomischen...

Since the work of FEENSTRA (2002), the standard ANDERSON & VAN WINCOOP (2003) Gravity Model has been estimated using a fixed effects approach. However, a fixed effects approach has a major drawback: it does not allow for the estimation of exporter- and importer-invariant variables. Thus,...

Better understand the consequences of unemployment in terms of labour market opportunities as well as psychological well-being is of primary importance for any policies aimed at reducing unemployment. One way by which unemployment may impact on future labour market outcomes is through a...

The paper contributes to the ongoing debate about the adequate technique to identify the impact of immigration. Initially the regression analysis on the basis of education-experience cells reveals that the impact of immigration on native wages in Germany is negative, but small. The subsequent...

Gravity models were developed to estimate the potential bilateral exports of cocoa under trade liberalization by the sixteen major cocoa producing countries to the US using panel data from 1989 to 2003. The results indicate that differences between resource endowment, relative size of economies,...
