Photovoltaic self-consumption after the support period: Will it pay off in a cross-sector perspective?

23.08.2018 | HWWI Research Paper 182 | von Lars Ehrlich, Jonas Klamka, André Wolf

We quantify the cost savings potential of photovoltaic self-consumption by single-family houses with small-scale roof-top photovoltaic (PV) systems in Germany against the background of recent storage applications after the end of the legal support period. We analyze different systems where an already installed PV system is combined with battery storage and/or a...

Interdisziplinäre Zusammenarbeit im Verbundprojekt. Herausforderungen und kritische Faktoren einer erfolgreichen Forschungskooperation

16.01.2018 | HWWI Research Paper | von Andreas Marcus Röhlig

Gerade innerhalb des heterogenen, durch Interdependenzen geprägten Themenspektrums der Umwelt- und Nachhaltigkeitsforschung reichen fachspezifische Betrachtungen meist zu kurz. Es besteht vielmehr die Notwendigkeit, Sichtweisen, Expertisen und Methoden verschiedener Disziplinen zusammenzuführen und zu integrieren, um so die komplexen Wirkungsmechanismen und Zusammenhänge...

This study explores the linkage between nine policy indicators of public childcare provision and maternal employment in terms of employment propensity and (conditional) working hours. We apply different identification strategies with a two-way fixed effects specification with individual and macro-level confounders as well as year and state fixed effects as our most...

The gender lifetime earnings gap – exploring gendered pay from the life course perspective

30.03.2017 | HWWI Research Paper 179, Hamburg | von Christina Boll, Malte Jahn, Andreas Lagemann

With the ‘gender lifetime earnings gap’ (GLEG), we introduce a new measure that captures the biographical dimension of gendered pay instead of hourly wages. We find that at the end of the employment career, women accumulated 49.8 % less earnings than men. Thus, the GLEG is more than twice as high as the current German gender pay gap.

Misperceptions of income distributions: Cross-country evidence from a randomized survey experiment

12.12.2016 | HWWI Research Paper 178, Hamburg | von Elisabeth Bublitz

This paper investigates whether the individual misperception of income distributions helps to explain why higher initial inequality levels do not correlate positively with redistribution. Based on data from a representative survey experiment it can be shown that most participants misperceive their own position in the income distribution.

Asset market response to monetary policy news from SNB press releases

21.09.2016 | HWWI Research Paper 177, Hamburg | von Hendrik Hüning

This paper analyses the effects of Swiss National Bank communication on asset prices. Results suggest that medium- and long-term bond yields respond to changes in the communicated inflation and GDP forecasts as well as to the degree of pessimism expressed in press releases.
