Resuming Social Contact after Months of Contact Restrictions: Social Traits Moderate Associations between Changes in Social Contact and Well-being

Humans possess a need for social contact. Satisfaction of this need benefits well-being, whereas deprivation is detrimental. However, how much contact people desire is not universal, and evidence is mixed on individual differences in the association between contact and well-being. This preregistered longitudinal study (N = 190) examined changes in social contact and well-being (life satisfaction, depressivity/anxiety) ...

Wohlstand schaffen oder verteilen? Ein kurzer Blick auf Wahl- und Regierungsprogramme

Wirtschaftspolitik in einer sozialen Marktwirtschaft möchte Wohlstand schaffen und verteilen. Dies zeigt sich in den Wahl- und Regierungsprogrammen auf Bundesebene seit 2002, allerdings mit sehr unterschiedlichen Akzenten. Zur Analyse wird deshalb die relative Häufigkeit der Begriffe „Soziales“ und „Wettbewerb“ in Programmen errechnet. Der daraus gebildete S/W-Koeffizient zeigt die Positionierung ...

Gemeinschaftsdiagnose: ohne russisches Gas droht eine scharfe Rezession in Deutschland

Die deutsche Wirtschaft steuert durch schwieriges Fahrwasser. Die Auftriebskräfte durch den Wegfall der Pandemiebeschränkungen, die Nachwehen der Coronakrise und die Schockwellen durch den Krieg in der Ukraine sorgen für gegenläufige konjunkturelle Strömungen. Allen Einflüssen gemeinsam ist ihre preistreibende Wirkung.

Does Green Public Procurement Trigger Environmental Innovations?

Green public procurement has gained high political priority and is argued to be an effective demand-side policy to trigger environmental innovations. However, the empirical evidence on its innovation impact is limited. We construct a novel firm-level dataset to investigate the effect of winning public procurement tenders with additional environmental award criteria on firms’ introduction of environmental ...

Einkommen und Kreditschulden privater Haushalte

Die wirtschaftlichen Auswirkungen der Coronapandemie haben im Jahr 2020 zu einem deutlichen Rückgang des realen BIP in Deutschland geführt. Für Erwerbstätige führte die Krise zu Arbeitsplatzverlusten, Einkommensverlusten – teilweise kompensiert durch Kurzarbeitergeld – und Rückgängen beim Einkommen aus Selbstständigkeit. Während sich die Einkommensseite für die privaten Haushalte damit schwach bis ...

Educational Selectivity and Immigrants’ Labour Market Performance in Europe

This article depicts the selectivity profiles of first-generation immigrants of multiple origins in 18 European destinations and investigates whether educational selectivity is relevant to their labour market performance. The theoretical account starts from the premise that the relative position individuals occupy in the educational distribution of their origin country represents—frequently unmeasured—characteristics ...

Mentoring as a Grassroots Effort for Integrating Refugees – Evidence from a Randomised Field Experiment

About 80 million people were displaced worldwide at the end of 2020. To support this highly vulnerable group, in recent years, local bottom-up initiatives proliferated to support refugee integration in hosting communities. This study examines a network intervention for refugees in collaboration with a social start-up whose mission is to match refugees and local volunteers to form friendships. We apply ...

Measurement Equivalence in Probability and Nonprobability Online Panels

Nonprobability online panels are commonly used in the social sciences as a fast and inexpensive way of collecting data in contrast to more expensive probability-based panels. Given their ubiquitous use in social science research, a great deal of research is being undertaken to assess the properties of nonprobability panels relative to probability ones. Much of this research focuses on selection bias, ...

The Pricing Structure of Legal Services: Do Lawyers Offer What Clients Want?

We analyze clients’ contract choices in auctions where Dutch law firms compete for standard cases such as labor disputes for individuals and collecting debts for businesses. In the auctions, lawyers can submit bids with any fee arrangement they prefer, including an hourly rate, a fixed fee, and a ‘mixed fee’: a time-capped fixed fee plus an hourly rate for any additional hours should the case take ...

Bürgergeld und Kindergrundsicherung als Einstiege ins bedingungslose Grundeinkommen?

Im Beitrag wird diskutiert, ob es sich bei der vorgesehenen Ablösung von Hartz IV durch ein Bürgergeld und den Aufbau einer Kindergrundsicherung eher um einen symbolischen Wandel handelt oder die im Herbst 2021 gewählte Ampel-Koalition einen substanziellen Neuanfang und eine grundlegende Reform des Wohlfahrtsstaates einleitet. Zusammenfassend werden die geplanten Maßnahmen der neuen Bundesregierung ...

Testing the Superstar Firm Hypothesis

Firms with superior productivity, labeled superstar firms, are argued to be the link between rising concentration and the fall of the aggregate labor share in the US. This analysis confirms that similar evidence is found within the European context: the market share and firm size increase, whereas the labor share decreases with productivity. One of the much discussed mechanisms behind this development ...

Experienced Well-Being and Labor Market Status: The Role of Pleasure and Meaning

This paper examines the experienced well-being of employed and unemployed workers. We use the survey-adapted Day Reconstruction Method of the Innovation Sample of the German Socio-Economic Panel Study to analyze the role of the employment status for well-being, incorporating time use. We use the novel P-index to summarize the average share of pleasurable minutes on a day and show that in contrast to ...

Social Norms and Preventive Behaviors in Japan and Germany during the COVID-19 Pandemic

According to a recent paper by Gelfand et al., COVID-19 infection and case mortality rates are closely connected to the strength of social norms: “Tighter” cultures that abide by strict social norms are more successful in combating the pandemic than “looser” cultures that are more permissive. However, countries with similar levels of cultural tightness exhibit big differences in mortality rates. We ...

Information Provision and Postgraduate Studies

This is the first paper to examine experimentally effects of information provision on beliefs about pecuniary and non-pecuniary returns of postgraduate education, enrolment intentions and realized enrolment. We find that our treatment causally affects beliefs measured six months after treatment. The effects on beliefs differ by gender and academic background, and we find that stated enrolment intentions ...

The Personality Traits of Self-Made and Inherited Millionaires

Very wealthy people influence political and societal processes by wielding their economic power through foundations, lobbying groups, media campaigns, as investors and employers. Because personality shapes goals, attitudes, and behaviour, it is important to understand the personality traits that characterize the rich. We used representative survey data to construct two large samples, one from the general ...

Assessing the Value of Data for Prediction Policies: The Case of Antibiotic Prescribing

We quantify the value of data for the prediction policy problem of reducing antibiotic prescribing to curb antibiotic resistance. Using varying combinations of administrative data, we evaluate machine learning predictions for diagnosing bacterial urinary tract infections and the outcomes of prescription rules based on these predictions. Simple patient demographics improve prediction quality substantially ...

Care and Careers: Gender (In)Equality in Unpaid Care, Housework and Employment

This article examines whether reducing care and housework duties and redistributing them within different-sex couples could further enhance gender equality on the labor market in terms of labor market participation for different employment types and actual working hours. Women around the world perform the majority of unpaid care and housework, with a large and persistent gap to men. Most research explains ...

Sovereign Bonds since Waterloo

This paper studies external sovereign bonds as an asset class. We compile a new database of 266,000 monthly prices of foreign-currency government bonds traded in London and New York between 1815 (the Battle of Waterloo) and 2016, covering up to 91 countries. Our main insight is that, as in equity markets, the returns on external sovereign bonds have been sufficiently high to compensate for risk. Real ...
