The Impact of Risk Aversion and Migrant Work Experience on Farmers’ Entrepreneurship: Evidence from China

Investing in entrepreneurship may be costly, and therefore risky, and entrepreneurship is also an economic endeavor that is highly dependent on entrepreneurial ability and risk appetite. In this study, data from 669 famers in southwest China were used as the sample, and we used three different methods to measure farmers’ risk aversion level, including DOSPRET (Domain-Specific Risk-Taking), SOEP (Simple ...

Stated Preferences and Actual Choices in German Health Insurance

Hypothetical bias is the discrepancy between stated preferences and actual choices. As such, it is one of the key issues regarding the use of hypothetical survey methods and therefore highly relevant for economists in understanding human behavior and refining policy interventions. Hypothetical survey methods are often used to inform our view on decision making in health and financial settings. However, ...

Semiparametric distribution regression with instruments and monotonicity

This paper proposes IV-based estimators for the semiparametric distribution regression model in the presence of an endogenous regressor, which are based on an extension of IV probit estimators and the idea of control functions. We discuss the causal interpretation of the estimators and two methods (monotone rearrangement and isotonic regression) to ensure a monotonically increasing distribution function. ...

Self-control is associated with health-relevant disparities in buccal DNA-methylation measures of biological aging in older adults

Self-control is a personality dimension that is associated with better physical health and a longer lifespan. Here, we examined (1) whether self-control is associated with buccal and saliva DNA-methylation (DNAm) measures of biological aging quantified in children, adolescents, and adults, and (2) whether biological aging measured in buccal DNAm is associated with self-reported health. Following preregistered ...

Do Changes in Personality Predict Life Outcomes?

The Big Five personality traits predict many important life outcomes. These traits, although relatively stable, are also open to change across time. However, whether these changes likewise predict a wide range of life outcomes has yet to be rigorously tested. This has implications for the types of processes linking trait levels and changes with future outcomes: distal, cumulative processes versus more ...

Longitudinal Within-Person Variability Around Personality Trajectories (online first)

Decades of research have identified average patterns of normative personality development across the lifespan. However, it is unclear how well these correspond to trajectories of individual development. Past work beyond general personality development might suggest these average patterns are oversimplifications, necessitating novel examinations of how personality develops and consideration of new individual ...

Does the German sports system recruit coaches with a functional personality?—Attempting an answer by comparing German basketball coaches with teachers and managers

Currently, there is no theory that identifies the ideal personality type for sports coaches. The study’s goal is to gain insight into the personalities of German basketball coaches and use existing study results from other professional groups to make recommendations for the content of coaches’ education. Given the German Olympic Sports Federation’s emphasis on comprehensive coach education that includes ...
