Zusammenfassung

Die Soziologie ökonomischen Wissens und der Wirtschaftswissenschaften stellte lange Zeit ein vernachlässigtes Forschungsfeld dar, das erst in der jüngeren Vergangenheit deutlichere Konturen angenommen hat. Der vorliegende Text versteht sich als Beitrag zu diesem Forschungsfeld und präsentiert eine Fallstudie zur modernen Makroökonomik. Wie verlaufen Prozesse von Wissenschaftswandel in einer Disziplin, die sowohl durch einen starken Einbezug in politische Steuerungskontexte als auch durch eine Fokussierung auf mathematische Modellierung gekennzeichnet ist? Durch Rekurs auf Experteninterviews mit Ökonomen sowie auf einschlägige Literatur werden Durchsetzungschancen und -hindernisse eines alternativen Modellierungs- bzw. Simulationsparadigmas (agentenbasierte Modellierung) ausgelotet. Agentenbasierte Modellierung setzt den in der modernen Makroökonomik ubiquitären Bezug auf die Walrasianische Allgemeine Gleichgewichtstheorie (und ihre diversen Fortentwicklungen, wie die Theorie rationaler Erwartungen) kontingent und konfrontiert makroökonomisches Denken mit ungewöhnlichen Formen von Komplexität.

Abstract

The sociology of economic knowledge and of economics only recently became a more busy and well-contoured area of research. The text at hand contributes to this research by presenting a case study on modern macroeconomics. How does knowledge proceed in a discipline that is both strongly aligned to political decision-making and committed to mathematical modeling? Drawing on expert interviews with macroeconomists as well as on the relevant literature, the text offers insights into the chances of success and the obstacles for an alternative, rivaling culture of modeling and simulation (agent based modeling). Agent based modeling opposes general equilibrium theory (and its various enhancements, like rational expectations theory) and confronts macroeconomics with unusual forms of complexity.
