Diversify or Not? – The Link between Global Sourcing of ICT Goods and Firm Performance

Our paper contributes to the discussion about Europe’s digital sovereignty. We analyze the relationship between firm performance and the diversification of sourcing countries for imported ICT goods. The analysis is based on administrative data for 3888 German manufacturing firms that imported ICT goods in the years 2010 and 2014. We find that firms that diversify the sourcing of ICT goods across multiple ...

Combining GPS Tracking and Surveys for a Mode Choice Model: Processing Data from a Quasi-Natural Experiment in Germany

This paper deals with the data generation process implemented for an analysis of the impact of the 9-Euro ticket on mode choice. We discuss the assumptions made and procedures used to process a raw dataset that is based on GPS traces of individuals’ movements and on survey data into the choice-set for a discrete choice model. Several steps of cleaning and merging are described in order to a) obtain ...

Working Life and Human Capital Investment: Causal Evidence from a Pension Reform

Stock market participation, remote work, and inequality

Stock market participation jumped upwards in Germany in the year 2020 by about 25%. A major cause for this was the enforced use of remote work. We show this by repeating a benchmark study with demanding data requests and adding remote work to the explanatory variables. Moreover, we implement an instrumental variables estimation based on commuting distance and work-from- home capacity. The...

Women in Management and the Gender Pay Gap

We analyze the impact of women’s managerial representation on the gender pay gap among employees on the establishment level using German Linked-Employer-Employee- Data from the years 2004 to 2018. For identification of a causal effect we employ a panel model with establishment fixed effects and industry-specific time dummies. Our results show that a higher share of women in management significantly ...

Should Mama or Papa Work? Variations in Attitudes towards Parental Employment by Country of Origin and Child Age

Employment among mothers has been rising in recent decades, although mothers of young children often work fewer hours than other women do. Parallel to this trend, approval of maternal employment has increased, albeit not evenly across groups. However, differences in attitudes remain unexplored despite their importance for better understanding mothers’ labour market behaviour. Meanwhile, the employment ...

Transactional Effects between Personality and Religiosity

Do changes in religiosity beget changes in personality, or do changes in personality precede changes in religiosity? Existing evidence supports longitudinal associations between personality and religiosity at the between-person level, such that individual differences in personality predict subsequent individual differences in change in religiosity. However, no research to date has examined whether ...

How Flexible Electrification Can Integrate Fluctuating Renewables

To phase out fossil fuels, energy systems must shift to renewable electricity as the main source of primary energy. In this paper, we analyze how electrification can support the integration of fluctuating renewables, like wind and PV, and mitigate the need for storage and thermal backup plants. Using a cost-minimizing model for system planning, we find substantial benefits of electricity demand in ...
