Der oft postulierte Zusammenhang zwischen sozialer Schichtung und Kriminalität ist weder theoretisch abgesichert noch empirisch eindeutig belegt. Ausgehend von der ökonomischen Theorie Gary S. Beckers wird ein erweitertes Modell kriminellen Handelns entwickelt, welches den Einfluss der Schichtzugehörigkeit auf die subjektive Wahrnehmung von Kosten, Nutzen und Entdeckungs-bzw. Erfolgswahrscheinlichkeit krimineller Handlungsalternativen einbezieht. Ferner werden die ebenfalls über die Klassenlage determinierten Anreize (Gelegenheitsstrukturen) und die Internalisierung von Normen („framing“) in das ökonomische Modell integriert. Das Modell wird anhand von Daten aus dem ALLBUS 1990 und 2000 für die Delikte Ladendiebstahl und Steuerbetrug überprüft. Entsprechend den theoretischen Erwartungen kann kein genereller negativer Zusammenhang zwischen Schichtzugehörigkeit und kriminellem Handeln festgestellt werden, wohl aber ein Zusammenhang zwischen Klassenlage und Delikttyp. Sozialstrukturell divergierende Erwartungen hinsichtlich Erfolg einer kriminellen Handlung und Gelegenheitsstrukturen sind bedeutsamer für die Wahl illegaler Handlungsalternativen als Abschreckung durch Strafe oder erwarteter Nutzen aus der Tat. Internalisierte Normvorstellungen machen kriminelle Handlungsalternativen unwahrscheinlich.

While most previous research has considered public service motivation (PSM) as the only motivational factor predicting (public) job choice, the authors present a novel, rational choice-based model which includes three motivational dimensions: extrinsic, enjoyment-based intrinsic and prosocial intrinsic. Besides providing more accurate person-job fit predictions, this new approach fills a significant research gap and facilitates future theory building.

Social identity poses one of the most important challenges to rational choice theory, but rational choice theorists do not hold a common position regarding identity. On one hand, externalist rational choice ignores the concept of identity or reduces it to revealed preferences. On the other hand, internalist rational choice considers identity as a key concept in explaining social action because it permits expressive motivations to be included in the models. However, internalist theorists tend to reduce identity to desire—the desire of a person to express his or her social being. From an internalist point of view, that is, from a viewpoint in which not only desires but also beliefs play a key role in social explanations as mental entities, this article rejects externalist reductionism and proposes a redefinition of social identity as a net of beliefs about oneself, beliefs that are indexical, robust, and socially shaped.

Adolescence is often viewed as a time of irrational, risky decision-making - despite adolescents' competence in other cognitive domains. In this study, we examined the strategies used by adolescents (N=30) and young adults (N=47) to resolve complex, multi-outcome economic gambles. Compared to adults, adolescents were more likely to make conservative, loss-minimizing choices consistent with economic models. Eye-tracking data showed that prior to decisions, adolescents acquired more information in a more thorough manner; that is, they engaged in a more analytic processing strategy indicative of trade-offs between decision variables. In contrast, young adults' decisions were more consistent with heuristics that simplified the decision problem, at the expense of analytic precision. Collectively, these results demonstrate a counter-intuitive developmental transition in economic decision making: adolescents' decisions are more consistent with rational-choice models, while young adults more readily engage task-appropriate heuristics.
