This paper provides empirical evidence on the party incumbency advantage in mayoral elections in Germany. Using a regression discontinuity design on a data set of about 25,000 elections, I estimate a causal incumbency effect of 38-40 percentage points in the probability of winning the next mayor...

This paper uses the gravity model of trade to investigate the link between foreign aid and exports in recipient countries. Most of the theoretical work emphasizes the negative impact of aid on recipient countries' exports primarily due to exchange rate appreciation, disregarding possible...

This paper assesses the impact of the Kyoto Protocol on CO2 emissions. With this aim a dynamic panel data model is estimated for a cross-section of 213 countries over the period 1960 to 2009. The model, based on a STIRPAT approach, also integrates the EKC approach and specifically considers the...

While the majority of micro studies finds that rural education increases agricultural productivity, various recent cross-country regressions analyzing the determinants of agricultural productivity were only able to detect an insignificant or even surprisingly negative effect of schooling. In...

This study aims to identify robust push and pull factors of human trafficking. I test for the robustness of 78 push and 67 pull factors suggested in the literature. By employing an extreme bound analysis, running more than two million regressions with all possible combinations of variables for...

The typical identification strategy in aid effectiveness studies assumes donor motives do not influence the impact of aid on growth. We call this homogeneity assumption into question, first constructing a model in which donor motives matter and then testing the assumption empirically.

This paper explores the economic relationship between foreign direct investment to developing countries and the export prices of the latter, measured by terms of trade. It is first shown that economic theory suggests such a relationship for various reasons but is inconclusive about the direction...

Ethnic fragmentation is a variable increasingly used in the economic literature to explain differences in economic development level, growth or the incidence of conflicts. Nearly all articles have in common that they treat ethnic fragmentation as a static, exogenous fact. Only recently some...

In der Studie wird untersucht, wie innerbetriebliche Übergänge aus Arbeitsgelegenheiten mit Mehraufwandsentschädigung in ungeförderte sozialversicherungspflichtige Beschäftigung (Klebeeffekte) entstehen. Zunächst werden die Gründe erörtert, warum die direkte Beschäftigungsintegration...

It is well known that individual's risk attitudes are related to behavioral outcomes such as smoking, portfolio decisions, and also educational attainment, but there is barely any evidence on whether parental attitudes affect the educational attainment of dependent children. We add to this...
