Nicht Genies, sondern die Arbeit vieler einzelner Forscher entscheidet über wissenschaftlichen Fortschritt. Allerdings nur, wenn bestimmte Bedingungen erfüllt sind. Die Wissenschaft hat nun einen Weg gefunden, die Weisheit der vielen für sich zu nutzen. Dieser Artikel erschien am 10. August 2021 als Gastbeitrag in der WELT. Es ist immer wieder mal die Rede von Schwarmintelligenz, die ...
This study tests the prediction that perceived corruption reduces ethical behavior. Integrating a standard “cheating” experiment into a broad household survey in rural Thailand, we find tentative support for this prediction: respondents who perceive corruption in state affairs are more likely to cheat and, thus, to fortify the negative consequences of corruption. Interestingly, there is a small group ...
Problem gamblers discount delayed rewards more rapidly than do non-gambling controls. Understanding this impulsivity is important for developing treatment options. In this article, we seek to make two contributions: First, we ask which of the currently debated economic models of intertemporal choice (exponential versus hyperbolic versus quasi-hyperbolic) provides the best description of gamblers’ discounting ...
In this article, we present an automated test procedure for examining the filter structure and instructions implemented in electronic questionnaires, and for checking the fit of a questionnaire to the targeted sample. With our approach, we can represent and describe questionnaires using mathematical graphs and specify questionnaire properties in a formal and standardised way. It also allows us deriving ...
Different local projection (LP) estimators for structural impulse responses of proxy vector autoregressions are reviewed and compared algebraically and with respect to their small sample suitability for inference. Conditions for numerical equivalence and similarities of some estimators are provided. A new LP type estimator is also proposed which is very easy to compute. Two generalized least squares ...
In der vorliegenden Studie wird untersucht, inwiefern sich der Einsatz eines spezifischen Zeitfensters bei Survey-Abfragen zum ehrenamtlichen und freiwilligen Engagement – im Vergleich zu Survey-Abfragen mit unspezifischen Zeitfenstern – auf die Selbstangaben von Befragten auswirkt. Die Grundlage der Untersuchung bildet ein Experiment, welches zu diesem Zweck im Rahmen des SOEP-Innovationssamples (SOEP-IS) ...
The German Socio-Economic Panel Study is a representative panel study for the German population, collecting data on a broad variety of topics of everyday life, including general wellbeing, household composition, educational aspirations and educational status, income and occupational biographies, leisure time activities, housing, health, political orientation and more. With its long running panel...
The literature on the effects of incentives in survey research is vast and covers a diversity of survey modes. The mode of probability-based online panels, however, is still young and so is research into how to best recruit sample units into the panel. This paper sheds light on the effectiveness of a specific type of incentive in this context: a monetary incentive that is paid conditionally upon panel ...
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, ...
