Meta-theory as a uniting framework for economics and global political economy

Abstract

This paper discusses the differences between orthodox and heterodox economics as well as between American and British Global Political Economy (GPE). It is found that the main differences within both disciplines are related to meta-theoretical premises. However, meta-theory turns out to be also a uniting factor between disciplines. Orthodox economics and American GPE mostly share positivist meta-theory, while heterodox economics and British GPE are largely based on critical realist meta-theory. Instead of building bridges within disciplines, it is suggested that it would be more feasible to combine some parts of orthodox economics with American GPE and some parts of heterodox economics with British GPE. This paper also discusses the role of mathematics in economics, critically assessing Tony Lawson's claim that there is no place for mathematical modelling in heterodox economics.
