Homo oeconomicus institutionalis
The Homo oeconomicus institutionalis [ ˈhɔmoː ɔe̯kɔˈnɔmɪkʊs ] ( Latin hŏmō oeconomicus , economic man) is a theoretical model from institutional and behavioral economics . Because the rationality postulate of Homo Oeconomicuswas often criticized as unrealistic and results were observed in behavioral economics that deviated significantly from the Homo Oeconomicus, it came to the development of the Homo oeconomicus institutionalis. With Homo oeconomicus institutionalis, additional action-determining aspects are included. In addition to cognitive limits, key aspects that are included are various preferences and the institutional framework. As action-determining aspects, situational-benefit-maximizing, rational-rule-bound, habitual and emotional-instinctive behavior are also considered.
For political decision-making problems, the model of Homo oeconomicus institutionalis can be used in the form of a step heuristic ( institutional analysis ). At each level it should be empirically checked whether the model of Homo oeconomicus institutionalis should be modified or not with regard to the decision problem. With this step heuristic, the question arises as to which action-determining factors are decisive for the incentive and obstacle situation of the respective actor.
