Using machine learning methods in a quasi-experimental setting, I study the heterogeneous effects of introducing waste prices - unit prices on household unsorted waste disposal - on waste demands and municipal costs. Using a unique panel of Italian municipalities with large variation in prices and observables, I show that waste demands are nonlinear. I find evidence of constant elasticities at low ...

This paper sheds new light on the role of communication for cartel formation. Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely ...

This paper investigates the effect of insolvency regulation reforms on cross-border debt and equity investments at aggregate and sectoral levels. Using disaggregated data from the ECB’s Securities Holdings Statistics by Sector (SHSS) database and the OECD indicators on efficiency of insolvency regulations, we find that investors increase their debt and equity holdings in the countries that undertook ...

In this paper, we investigate how European households changed the diversity of their financial portfolios in response to the Great Financial and the subsequent European Debt Crisis. For this purpose we apply a Difference-in-Differences (DiD) approach estimated as a correlated random effects (CRE) model to six waves of the Survey of Health, Ageing and Retirement in Europe (SHARE). We find that households ...

We introduce a selection model-based imputation approach to be used within the Fully Conditional Specification (FCS) framework for the Multiple Imputation (MI) of incomplete ordinal variables that are supposed to be Missing Not at Random (MNAR). Thereby, we generalise previous work on this topic which involved binary single-level and multilevel data to ordinal variables. We apply an ordered probit ...

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 ...

This study explores how researchers’ analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions ...

Adequate immunity to COVID-19 apparently cannot be attained in Germany by voluntary vaccination alone, and therefore the introduction of mandatory COVID-19 vaccination is still under consideration. We present findings on the potential acceptance of such a requirement by the German population, and we report on the reasons given for accepting or rejecting it and how these reasons vary according to population ...

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 ...

Purpose Cross-sectional studies found high levels of depression and anxiety symptoms, and loneliness during the first wave of the COVID-19 pandemic. Reported increases were lower in longitudinal population-based findings. Studies including positive outcomes are rare. This study analyzed changes in mental health symptoms, loneliness, and satisfaction. Methods Respondents of the German Socio-Economic ...
