Von John Maynard Keynes zu "Modern Macro"

Im Zuge der Herausbildung der Finanzmärkte und unter dem Eindruck der Finanzkrise ist unter dem Label „Performativität der Ökonomik“ ein weiterer Diskussionsstrang entstanden:

Das Lehrmaterial der Landeszentrale für politische Bildung Baden-Württemberg lotet die Möglichkeiten, aber auch Grenzen neoklassischer Wirtschaftsmodelle aus und fragt, inwiefern soziale Gerechtigkeit die ökonomische Effizienz befördern kann.

Education policy seeks to ensure equality in access, equality within the classroom and in teaching- learning processes, and equality in outcomes. This course encourages students to assess and evaluate the extent to which these objectives are met in practice and the ways in which educational outcomes are shaped by, as well as alter, gendered social norms.

This paper starts with an evaluation of three common arguments against pluralism in economics: (1) the claim that economics is already pluralist, (2) the argument that if there was the need for greater plurality, it would emerge on its own, and (3) the assertion that pluralism means ‘anything goes’ and is thus unscientific. Pluralist responses to all three arguments are summarized. The third argument is identified to relate to a greater challenge for pluralism: an epistemological trade-off between diversity and consensus that suggests moving from a discussion about ‘pros’ and ‘cons’ towards a discussion about the adequate degree of plurality. We instantiate the trade-off by showing how it originates from two main challenges: the need to derive adequate quality criteria for a pluralist economics, and the necessity to propose strategies that ensure the communication across different research programs. The paper concludes with some strategies to meet these challenges.
