Schumpeter’s Split Between “Pure” Economics and Institutional Economics: Why Methodological Individualism Was Not Fully Considered

While Joseph A. Schumpeter is classified as a pioneer of evolutionary economics in a wide sense and of entrepreneurship and innovation management in a narrower sense, Schumpeter is less known for his contributions in the area of scientific methodology and history of science. The paper deals with methodological premises in Schumpeter’s scientific positioning. In 1908, in his Das Wesen und der Hauptinhalt der theoretischen Nationalökonomie, Schumpeter developed and pioneered his methodological individualism which is very much acknowledged. However, comparing these early positions with methodological writings in his History of Economic Analysis (1954) shows that he has not really shifted from methodological individualism to an institutional perspective that addresses the academic interplay and sees economic action rooted in historical predispositions, paths and social constraints.     

Guilt Appeals and Prosocial Behavior: An Experimental Analysis of the Effects of Anticipatory Versus Reactive Guilt Appeals on the Effectiveness of Blood Donor Appeals

This study investigates the effectiveness of guilt-arousing communication in promoting prosocial behavior. By analyzing the distinct effects of anticipatory versus reactive guilt appeals, we contribute to the discussion of guilt appeals as drivers of prosocial behavior, especially blood donation. Research on persuasive communication provides the theoretical basis of our study and we validate our hypotheses by means of two 2?×?2 factorial between-subjects designs. We find that anticipatory rather than reactive guilt appeals are more effective in generating prosocial action tendencies. Compared to noninformational reference group influences, messages endorsed by members of informational reference groups yielded more favorable attitudinal responses. Besides their significant main effect, two-sided messages reinforce the favorable impact of anticipatory guilt appeals. The study concludes with practical implications for nonprofit organizations and public blood donor services as well as avenues for future research.
