    2D:4D Does Not Predict Economic Preferences: Evidence from a Large, Representative Sample

    The digit ratio (2D:4D) is considered a proxy for testosterone exposure in utero, and there has been a recent surge of studies testing whether 2D:4D is associated with economic preferences. Although the results are not conclusive, previous studies have reported statistically significant correlations between 2D:4D and risk taking, altruism, positive reciprocity, negative reciprocity and trust. ...

    2D:4D and Self-Employment Using SOEP Data: A Replication Study

    The 2D:4D digit ratio, the ratio of the length of the 2nd digit to the length of the 4th digit, is often considered a proxy for testosterone exposure in utero. A recent study by Nicolaou et al. (2018) reported an association between the left-hand 2D:4D and self-employment (in a sample of about 1,000 adults). In this pre-registered study we replicate these results on a new and larger sample of about ...

    Entrepreneurship, Management, and Cognitive Reflection: A Preregistered Replication Study With Extensions

    Intuition is a central element of entrepreneurial decision-making. We conceptually replicate a published study by using new representative data from 1961 adults and the widely used Cognitive Reflection Test, which assesses the ability to avoid intuitive decisions and to switch to an analytical process. We extend the analysis by exploring occupational sorting versus environmental influence as mechanisms, ...

    Adding Household Surveys to the Behavioral Economics Toolbox: Insights from the SOEP Innovation Sample

    While laboratory and field experiments are the major items in the toolbox of behavioral economists, household panel studies can complement them and expand their research potential. We introduce the German Socio-Economic Panel’s Innovation Sample (SOEP-IS), which offers researchers detailed panel data and the possibility to collect personalized experimental and survey data for free. We discuss what ...

    Competition and Moral Behavior: A Meta-Analysis of Forty-Five Crowd-Sourced Experimental Designs

    Does competition affect moral behavior? This fundamental question has been debated among leading scholars for centuries, and more recently, it has been tested in experimental studies yielding a body of rather inconclusive empirical evidence. A potential source of ambivalent empirical results on the same hypothesis is design heterogeneity—variation in true effect sizes across various reasonable experimental ...

    Changes in Risk Attitudes Vary across Domains throughout the Life Course

    Risk attitudes are important predictors of various economic decisions and socioeconomic outcomes. Although studies show that peoples’ general willingness to take risks decreases with age, there are few reports on the age dependence of domain-specific risk attitudes. Drawing on the Socio-Economic Panel (SOEP), this study employs a proxy variable approach to disentangle age from periodic and cohort effects, ...

    Cognitive Reflection and 2D:4D: Evidence from a Large Population Sample

    Bosch-Domènech et al. (2014) reported a negative association between 2D:4D, a suggested marker of prenatal testosterone exposure, and the Cognitive Reflection Test (CRT) in a sample of 623 university students. In this pre-registered study, we test if we can replicate their findings in a general population sample of over 2,500 individuals from Germany. We find no statistically significant association ...

    Discounting Behavior in Problem Gambling

    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 ...

    2D:4D and Self-Employment: A Preregistered Replication Study in a Large General Population Sample

    The 2D: 4D digit ratio, the ratio of the length of the second finger to the length of the fourth finger, is often considered a proxy for testosterone exposure in utero. A recent study reported, among other things, an association between the left-hand 2D:4D and self-employment in a sample of 974 adults. In this preregistered study, we replicate the 2D:4D results on a sample of more than 2100 adults ...
