Changes in Risk Attitudes Vary across Domains throughout the Life Course

Risk attitudes are important predictors of various economic decisions and socioeconomic outcomes. Although studies show that peoples’ general willingness to take risks decreases with age, there are few reports on the age dependence of domain-specific risk attitudes. Drawing on the Socio-Economic Panel (SOEP), this study employs a proxy variable approach to disentangle age from periodic and cohort effects, ...

Sin Taxes and Self-Control

According to theory, "sin taxes" are welfare improving if consumers with low self-control respond at least as much to the tax as consumers with high self-control. We investigate empirically if demand response to soft drink and fat tax variations in Denmark depends on consumers' self-control. We use a unique home-scan panel that includes a survey measure of self-control. When taxes increase, consumers ...

Flexible Heat Pumps: Must-Have or Nice to Have in a Power Sector with Renewables?

Heat pumps are a key technology for reducing fossil fuel use in the heating sector. A transition to heat pumps implies an increase in electricity demand, especially in cold winter months. Using an open-source power sector model, we examine the power sector impacts of a massive expansion of decentralized heat pumps in Germany in 2030, combined with buffer heat storage of different sizes. Assuming that ...

SOEP-LEE2: Linking Surveys on Employees to Employers in Germany

This article presents the new linked employee-employer study of the Socio-Economic Panel (SOEP-LEE2), which offers new research opportunities for various academic fields. In particular, the study contains two waves of an employer survey for persons in dependent work that is also linkable to the SOEP, a large representative German annual household panel (SOEP-LEE2-Core). Moreover, SOEP-LEE2 includes ...

The Impact of Public Procurement on Financial Barriers to General and Green Innovation

This study investigates whether public procurement mitigates or exacerbates innovative enterprises’ financial constraints. We distinguish between general and environmentally beneficial innovative enterprises. Theory suggests that the treatment effects of public procurement, particularly when mediated by the demand-pull effect, may lower a company’s funding constraints for innovation. We test this theory ...

Ukrainian Refugees: Nearly Half Intend to Stay in Germany for the Longer Term

Millions of Ukrainians have been displaced by the Russian war on Ukraine, with over one million alone coming to Germany since the beginning of the war. Data from the second survey wave of the IAB-BiB/FReDA-BAMF-SOEP Survey of Ukrainian Refugees in Germany study show that as of the beginning of 2023, an increasing share of Ukrainian refugees plan on staying in Germany for the longer term. Around three ...

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 ...
