This paper reviews the adjustments of the feed-in tariff for new solar photovoltaics (PV) installations in Germany. As PV system prices declined rapidly over the last years, the German government implemented automatic mechanisms to adjust the support level for new installations in response to deployment volumes. This paper develops an analytic model to simulate weekly installations of PV systems ?30 ...
Purpose. This paper aims to present the IZA Evaluation Dataset, a newly created data source allowing for the evaluation of active labor market policies in Germany. Design/methodology/approach. The paper's approach is a description of the sampling and contents of the IZA Evaluation Dataset and an outline of its research potential. Findings. The evaluation of active labor market policies is often confronted ...
Purpose. Labor market programs may affect unemployed individuals' behavior before they enroll. The aim of this paper is to study whether such ex ante effects differ according to ethnic origin. Design/methodology/approach. The authors apply a method that relates self-reported perceived treatment rates and job search behavioral outcomes, such as the reservation wage or search intensity, to each other. ...
Purpose: The aim of this paper is to study the economic effects of risk attitudes, time preferences, trust and reciprocity and to compare natives and second generation migrants. Design/methodology/approach: This paper is based on the IZA Evaluation Dataset, a recently collected survey of a representative inflow sample into unemployment in Germany. The data include a large number of migrant-specific ...
Purpose: This paper seeks to shed further light on the native-migrant differences in economic outcomes. The aim is to investigate labor market reintegration, patterns of job search, and reservation wages across unemployed migrants and natives in Germany. Design/methodology/approach: The paper is based on the IZA Evaluation Dataset, a recently collected rich survey of a representative sample of entrants ...
Findings from many behavioral genetic studies utilizing the classical twin design suggest that genetic and non-shared environmental effects play a significant role in human personality traits. This study focuses on the methodological advantages of extending the sampling frame to include multiple dyads of relatives. We investigated the sensitivity of heritability estimates to the inclusion of sibling ...
We investigate the exertion of market power in the global crude oil market over the past years. Recognizing the difficulty of identifying market power in the crude oil market by empirical studies, we propose a numerical partial equilibrium model formulated as a mixed complementarity problem. Our approach allows for strategic behavior in a Nash-Cournot market, a Stackelberg leader-follower game, an ...
