In the fight against antibiotic resistance, reducing antibiotic consumption while preserving healthcare quality presents a critical health policy challenge. We investigate the role of practice styles in patients’ antibiotic intake using exogenous variation in patient-physician assignment. Practice style heterogeneity explains 49% of the differences in overall antibiotic use and 83% of the differences ...

Artificial Intelligence has the potential to improve human decisions in complex environments, but its effectiveness can remain limited if humans hold context-specific private information. Using the empirical example of antibiotic prescribing for urinary tract infections, we show that full automation of prescribing fails to improve on physician decisions. Instead, optimally delegating a share of decisions ...

People have a need to form and maintain fulfilling social contact, yet they differ with respect to with whom they satisfy the need and how quickly this need is deprived or overly satiated. These social dynamics across relationships and across time are theoretically delineated in the current article. Furthermore, we developed a questionnaire to measure individual differences in three aspects of such ...

This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt taking. We show suggestive evidence for a link between overconfidence and borrowing behavior in a representative survey of German households (German Socio-Economic Panel–Innovation Sample [GSOEP-IS]). This motivates a laboratory experiment to study causality behind these effects. In two experiments, ...

This study examines the familial ties in the social support network of refugees in Germany. It investigates whether distance to family plays a role in the provision of emotional and informational support and how this relationship is moderated by social network services (SNS). Using data from the IAB-BAMF-SOEP Survey of Refugees (N = 5237), the paper provides evidence for a family-centred network. Increasing ...

We study the relationship between crowding and performance in the active mutual fund industry. Using the equity holdings overlap of 17,364 global funds, we find that funds that crowd into the same stocks underperform passive benchmark funds by 1.4% per year. The negative returns to crowding can at least in part be explained by excess demand for liquidity and the associated discount for holding liquid ...

We investigate panel conditioning effects in a long-running probability-based online panel of the general population through a large-scale experiment conducted in 2020. Our experiment was specifically designed to study the effect of intensifying the surveying frequency for the treatment group (N = 5,598 panel members) during a 16-week corona study while keeping the control group (N = 799 panel members) ...

Although maritime cabotage emits comparatively less CO2 per tonne kilometre than other means of transportation, the potential contribution of Brazil’s cabotage policy toward tackling climate change remained largely unexplored throughout its legislative process. Hence, to gather insights into how climate change can be integrated into sectoral policies, we apply Kingdon’s Multiple Streams Framework (MSF) ...

The outbreak of the COVID-19 pandemic has led to a vast increase in the demand for fast, frequent, and multi-faceted data to study the impact of the pandemic on people’s lives. Existing data collection infrastructures had to be adapted quickly during the early phase of the pandemic to meet this data demand. Our research group contributed to this by conducting the Mannheim Corona Study (MCS), a longitudinal ...

We examine how the gender of business owners is related to the wages paid to female relative to male employees working in their firms. Using Finnish register data and employing firm fixed effects, we find that the gender pay gap is—starting from a gender pay gap of 11 to 12%—two to three percentage points lower for hourly wages in female-owned firms than in male-owned firms. Results are robust to how ...

Shared pooled mobility has been hailed as a sustainable mobility solution that uses digital innovation to efficiently bundle rides. Multiple disciplines have started investigating and analyzing shared pooled mobility systems. However, there is a lack of cross-community communication making it hard to build upon knowledge from other fields or know which open questions may be of interest to other fields. ...

In this paper, we model a fossil fuel embargo as a temporary quantity constraint on fossil fuel imports and wecompare the impact with the effect of a fossil fuel price shock. We show that while both shocks have similar responses of output and inflation, they differ with respect to the reaction of other macroeconomic components,such as consumption, exports and the trade balance. In particular, an embargo ...

This paper investigates the effects of survivor benefits (SB) on the labour supply of widows. Using richadministrative data on the Dutch population and a reform that considerably restricted eligibility to SB, weidentify the causal effect of SB on labour supply. Using a regression discontinuity design strategy based onthe cohort-based implementation of the reform, we show that labour income after spousal ...

We estimate a dynamic structural model of labor supply, retirement, and informal caregiving to study short and long-term costs of informal caregiving in Germany. Incorporating labor market frictions and the German tax and benefit system, we find that in the absence of Germany’s public long-term insurance scheme, informal elderly care has adverse and persistent effects on labor market outcomes and, ...

How does a monetary union alter the impact of business cycle shocks at the household level? We develop a Heterogeneous Agent New Keynesian model of two countries (HANK) and show in closed form that a monetary union shifts the adjustment to a shock horizontally across countries, within the brackets of the union-wide wealth distribution, rather than vertically, that is, across the brackets of the union-wide ...

This paper addresses the pressing need for rapid decarbonization of energy systems by examining the role of nuclear power in future energy scenarios collected in the IPCC database. Despite their explorative character, energy scenarios can influence decision-makers or might be used to promote certain technology developments. They are increasingly subject to the integration into real-world settings and ...
