All are agreed that orthodox economics is unsatisfactory but there is wide disagreement, especially among heterodox critics, whether the problems lie at the level of substantive theory or at the level of methodology. This paper gives first an overview of the methodological questions at issue....

There is no way around it: each theory rests on a tiny set of foundational propositions. Standard economics rests on behavioral axioms. After a long intellectual detour it should be clear by now that behavioral axioms are the wrong formal departure point. Being beyond repair, they have to be...

Standard economics is known to be incapable of integrating the real and the monetary sphere. The ultimate reason is that the whole theoretical edifice is built upon a set of behavioral axioms. Therefore, the formal starting point is moved to structural axioms. This makes it possible to formally...

The formal foundations of theoretical economics must be nonbehavioral and epitomize the interdependence of real and nominal variables that constitutes the monetary economy. This is a cogent conclusion from the persistent collapse of behavioral and real models. Conceptual rigor demands, first, to...

This note proposes a growth model that is derived from the standard Solow growth model by replacing the neoclassical production function with Kaldor's technical progress function while maintaining a marginalist theory of factor prices in the spirit suggested by von Weizsäcker (1966, 1966b). The...

Macroeconomics must take radical uncertainty into account, if it aims at contributing to the solution of serious real-world problems such as climate change. Allowing for radical uncertainty must happen at two levels: the level of modeling and the level of the scientifi c discipline. I argue that...

In diesem Beitrag geht es darum, den Postkeynesianismus als paradigmatische Alternative zum herrschenden neoklassischen Mainstream etwas näher kennenzulernen. Es zeigt sich sehr schnell, dass der Postkeynesianismus keine einheitliche Denkschule darstellt, sondern vielmehr eine Vielzahl von...

The push to pluralise the economic discipline involves making informed decisions about which paradigm to adopt, requiring a deep understanding of each paradigm's characteristics and affiliations. Once paradigmatic choices are made, different theories can either collaborate effectively or require...

Der vorliegende Beitrag analysiert Helmedags neuste Version des Saldenmechanischen Modells (SM), mit dessen Hilfe eine angeblich langfristig bestehende, relative Konstanz der Lohnstückkosten erklärt werden soll. Die realen Lohnstückkosten steigen jedoch in der Bundesrepublik Deutschland...
