(Un-)gleichheit und Gerechtigkeit waren schon immer Kernbestandteil eines jeden politischen Konzeptes, welches das Wohl der Menschen in den Mittelpunkt rückte. Die Idee der Gleichheit ist so alt wie die der Demokratie selbst und neben instrumentellen Gründen, aus denen man (Un-)gleichheit...

This paper uses panel data for 116 countries over the period 1995-2016 to investigate the heterogeneity of the debt-growth nexus across countries and the factors underlying it. In the first step, the grouped fixed effects (GFE) estimator proposed by Bonhomme and Manresa (2015) is used to...

This paper investigates the link between health care expenditures and GDP for a sample of 21 OECD countries using recent developed panel cointegration techniques. In contrast to previous studies, the analysis accounts for the fact that health care expenditures are not only determined by income....

In this paper we investigate the relationship between per capita income and foreign aid for a panel of 131 (alternatively 52) recipient countries over the period 1960 to 2006 by employing annual data and 5-year averages. Reliance on standard panel estimation techniques, such as 2-ways FE...

This paper investigates whether Aid for Trade (AfT) leads to greater exports in recipient countries. Using panel data and panel quantile regression techniques, our results suggest that total AfT disbursements promote the export of goods and services, but is limited primarily to exporters above...

This paper examines the long-run relationship between energy consumption and real GDP, including energy prices, for 25 OECD countries from 1981 to 2007. The distinction between common factors and idiosyncratic components using principal component analysis allows to distinguish between...

This paper challenges the common view that exports generally contribute more to GDP growth than a pure change in export volume, as the export-led growth hypothesis predicts. Applying panel cointegration techniques to a production function with non-export GDP as the dependent variable, we find...
