Prior to the introduction of mother tongue based education in 1994, the language of instruction for most subjects in Ethiopia's primary schools was the official language (Amharic) - the mother tongue of only one third of the population. This paper uses the variation in individual's exposure to...

While there is some hope that the ongoing climate change negotiations will soon come up with concrete, time scheduled and binding emission reduction commitments, the question of how to achieve these targets is still unsolved. The objective of this paper is to analyse alternative settings of an...

Different stochastic simulation methods are used in order to check the robustness of the outcome of policy simulations with a macroeconometric model. A macroeconometric disequilibriummodel of the West German economy is used to analyze a reform proposal for the tax system. The model was estimated...

We analyze the effectiveness of public works programs (PWP, Arbeitsbeschaffungsmaßnahmen) in east Germany as measured by their effects on individual future reemployment probabilities in regular jobs. These are estimated by discrete hazard rate models on the basis of individual-level panel data....

We study the effect of inflowing remittances - a major source of capital for many countries - on tax-revenues and tax-policy. Instrumenting remittances with changes in the oil-price interacted with a country's distance to oil-producing countries, we find that remittances have a large positive...

In this paper, a practicable scheme of SO2-emission permits for European power producers is developed. Background is the second UN-ECE Sulphur Protocol from 1994 (Protocol of Oslo). After discussing some theoretical models of spatially differentiated permit schemes, evaluating the U.S. Acid Rain...

We estimate the employment effects of training, intervention works (subsidised employment), and public works programmes in Poland. The analysis is based on retrospective monthly calendar information on the labour force state and active labour market programme (ALMP) participation between January...

Dieser Beitrag stellt ausgew ahlte Ergebnisse des vom Zentrum für Europäische Wirtschaftsforschung (ZEW) im Auftrag des IAB und des Ministeriums für Arbeit und Soziales Rheinland-Pfalz bearbeiteten Forschungsprojekts "Arbeitsplatzeffekte gemeinnütziger Arbeitnehmerüberlassungen in...

I study the causal effect of the European Union Emissions Trading System (EU ETS) on the productivity of German manufacturing firms. Using administrative firm-level data, I estimate robust production functions for narrowly defined industries. This approach allows for an endogenous dynamic...

This paper integrates innovation input and output effects of R&D subsidies into a modified Crépon–Duguet–Mairesse (CDM) model. Our results largely confirm insights of the input additionality literature, i.e. public subsidies complement private R&D investment. In addition, results point to...
