Public childcare and maternal labour supply – new evidence for Germany

03.11.2017 | HWWI Research Paper 180, Hamburg | von Christina Boll, Andreas Lagemann

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.



The EU Gender Earnings Gap: Job Segregation and Working Time as Driving Factors

13.09.2016 | HWWI Research Paper 176, Hamburg | von Christina Boll, Anja Rossen, André Wolf

This paper estimates size and impact factors of the gender pay gap in Europe. We find that about one third of the gap can be traced back to the role of the explanatory factors included in our analysis. The sectoral segregation of genders is identified as the most important barrier to gender pay equality in European countries.

Hamburg’s port position: Hinterland competition in Central Europe from TEN-T corridor ports

12.09.2016 | HWWI Research Paper 175, Hamburg | von Franziska Biermann, Jan Wedemeier

We analyze the hinterland position of the German port of Hamburg in Central Europe. We show how much the economic potential can be increased due to infrastructure improvements, and how it affects the competitive position in hinterland transport. However, besides the hinterland infrastructure there are other determinants relevant for port competition. ...
