This study addresses a fundamental concern of research on economic ethics by examining the values of economics. While other studies have linked the study of economics to the adoption of rational economic behavior, this study goes one level deeper, investigating the values that underpin neoclassical economics and whether they are transmitted to students. We find that the study of economics is associated with an increase in hedonism and power values, a decrease self-direction value, and possibly a decrease in universalism value. (...) We measure value change among economics students using a quasi-experimental research design in accordance with the methodology of research on academic socialization. We discuss the practical implications of the internalization of economic values. (shrink)
