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 ...
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 ...
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...
The Berlin IO Day is a one-day workshop sponsored by the Berlin Centre for Consumer Policies (BCCP) and the Society of Friends at DIW Berlin (VdF) and supported by the Berlin's leading academic institutions, including DIW Berlin, ESMT Berlin, Freie Universität Berlin, Humboldt-Universität zu Berlin, and Technische Universität Berlin. The aim is to create an international forum for...
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...
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 ...
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 ...
As part of the 2019 frequency allocation process for mobile communications, the Federal Network Agency required network providers to achieve a certain level of mobile network coverage for the population. Cooperation between different network providers was also permitted for the first time, although it was not specified what forms of cooperation are permitted. Using a model, this report shows that providers ...
