The Effect of Social Comparison on Debt Taking: Experimental Evidence

A number of studies show that there is a link between social comparison and high levels of household debt. However, the exact mechanisms behind this link are not yet well understood. In this paper, we disentangle two mechanisms by performing a lab experiment designed to study the effects of social image concerns and peer information on consumption choices financed through debt taking. We find that ...

Expectation Management of Policy Leaders: Evidence from COVID-19

This paper studies how the communication of political leaders affects the expectation formation of the public. Specifically, we examine the expectation management of the German government regarding COVID-19-related regulatory measures during the early phase of the pandemic. We elicit beliefs about the duration of these restrictions via a high-frequency survey of individuals, accompanied by an addi-tional ...

The Role of Physician-Patient Similarity in Diagnosis and Treatment Decisions: Evidence from Antibiotic Prescribing

Physicians in primary care provide initial diagnosis and treatment for a diverse set of patients. However, whereas patients are demographically and socio-economically heterogeneous, physicians typically come from affluent and highly-educated backgrounds. As a result, there is often a mismatch between physicians and the community they serve. I investigate the role of patient-physician similarity...

Fairness in Markets and Market Experiments

Whether pro-social preferences identified in economic laboratory experiments survive in natural market contexts is an important and contested issue. We investigate how fairness in a laboratory experiment framed explicitly as a market exchange relates to preferences for fair trade products elicited before and at the end of the market experiment. We find that the willingness to buy at a higher price...

The Effect of Self-Control on Borrowing: Experimental Evidence

This paper examines the effect of reduced self-control on debt-taking in a laboratory experiment. We manipulate self-control using an ego depletion task and show that it is effective. Following the ego depletion task, participants can anonymously buy hot drinks on credit. We find no significant average effects, but find that treated individuals that have low financial literacy are more likely to buy ...

Financial Education Measures Are Effective: Germany Should Develop a National Strategy for Financial Education

The OECD recommends its member countries implement national strategies for financial education. Many other countries, such as China and India, also have such strategies, whereas Germany does not. The strongest reason for rejecting such a strategy is the supposition that financial education interventions are ineffective. Using all available randomized experimental studies, this study investigates and ...
