Overeducation - New Evidence for 25 European Countries

08.04.2016 | HWWI Research Paper 173, Hamburg | von Christina Boll, Julian Sebastian Leppin, Anja Rossen, André Wolf

This study investigates the incidence of overeducation among workers in the EU and its underlying factors. Our findings point to a considerable variation in the potential determinants of overeducation across countries as well as across skill levels. This variation is not restricted to job-related characteristics, but interestingly also concerns household variables. ...

A cross-country comparison of gender differences in job-related training - The role of working hours and the household context

14.03.2016 | HWWI Research Paper 172, Hamburg | von Christina Boll, Elisabeth Bublitz

Regarding gender differences, theory suggests that in a partnership the individual with the lower working hours and earnings position should exhibit lower training participation rates. Since women are more likely to match this description, we investigate whether systematic group differences explain gender variation.

Green Accounting, Institutional Quality and Investment Decisions: Macroeconomic Implications from an Analysis of the Oil and Mining Sector

01.01.2016 | HWWI Research Paper | von Jana Stöver

Institutional quality is assumed to determine the (perceived) risk in the face of which oil and mining firms determine their investment level in physical and natural capital. Since both types of capital are used jointly in production, the firms face a dual investment decision. ...

We investigate the impact of environmental regulation on firm performance and investment behavior. Exploiting the case of a German water withdrawal regulation that is managed on the state level, we analyze firms’ reactions to an increase in the water tax using a regression- adjusted difference-in-differences approach.

Optimal Public Information Dissemination – Introducing Multiplier Effects into a Generalized Beauty Contest

20.10.2015 | HWWI Research Paper 169, Hamburg | von Hendrik Hüning, Lukas Meub

We develop a two-period generalized beauty contest to study the optimal level of publicity when disclosed information is subject to multiplier effects. We build upon the static case where all agents receive a private signal about an unknown fundamental state and only a fraction of all agents receive an additional public signal. We show that in the unique equilibrium of...

Impact of Welfare Sanctions on Employment Entry and Exit from Labor Force

22.09.2015 | HWWI Research Paper 168 | von Katja Hillmann, Ingrid Hohenleitner

Similar to numerous other European countries, Germany’s unemployment policy went through a paradigm shift in 2005, towards activation policy by tightening their monitoring and sanction regime. With our study, we aim to provide causal evidence for whether an intended positive effect of benefit sanctions on employment entry of welfare recipients has been bought at the...
