Firm Specific Wage Spread in Germany - Decomposition of regional differences in inter firm wage dispersion

If firm-specific effects explain wage dispersion between firms, a decomposition of the wage … dispersion between firms is necessary. The decomposition can help to find out, whether the economy-wide results for different …

Time-Varying Occupational Contents: An Additional Link between Occupational Task Profiles and Individual Wages
Fedorets, Alexandra - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2011
By analyzing occupational task profiles, an occupational change can be split up into two components (1) transferability of task portfolios between occupations and (2) change in the value of the occupation-employee match. Extending the task-based approach of Gathmann and Schönberg (2009) by...

Changes in Occupational Demand Structure and their Impact on Individual Wages
Fedorets, Alexandra - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2011
This paper estimates wage losses arising due to changes in the structure of demand for occupations. The data on occupational changes made for the sake of adjustment to the changes in the demand structure come from the German reunification of 1990. Endogenous occupational changes are instrumented...

Peer Effects and Students’ Self-Control
Buechel, Berno; Mechtenberg, Lydia; Petersen, Julia - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2014
We conducted a multi-wave field experiment to study the interaction of peer effects and selfcontrol among undergraduate students. We use a behavioral measure of self-control based on whether students achieve study related goals they have set for themselves. We find that both self-control and the...

Testing Missing at Random using Instrumental Variables
Breunig, Christoph - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2015
This paper proposes a test for missing at random (MAR). The MAR assumption is shown to be testable given instrumental variables which are independent of response given potential outcomes. A nonparametric testing procedure based on integrated squared distance is proposed. The statistic’s...

Oracally Efficient Two-Step Estimation of Generalized Additive Model
Liu, Rong; Yang, Lijian; Härdle, Wolfgang Karl - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2011
Generalized additive models (GAM) are multivariate nonparametric regressions for non-Gaussian responses including binary and count data. We propose a spline-backfitted kernel (SBK) estimator for the component functions. Our results are for weakly dependent data and we prove oracle efficiency....

Can crop yield risk be globally diversified?
Liu, Xiaoliang; Xu, Wei; Odening, Martin - Sonderforschungsbereich 649: Ökonomisches Risiko, … - 2011
In 2007 and 2008 world food markets observed a significant price boom. Crop failures simultaneously occurring in some of the world’s major production regions have been quoted as one factor among others for the price boom. Against this background, we analyse the stochasticity of crop yields in...
