Thousands of books have been written since the mid 20th century dedicated to exploring orthodox or mainstream economics. Little more than a handful of these books have reflected upon the philosophical and methodological underpinnings of economics. The result is not only that orthodox economics has marginalised heterodox alternatives and come to dominate economics departments in universities around the world, but also the impression has been created that discussion of philosophy and methodology is simply a wasteful distraction from `doing' economics.
Orthodox economics has not benefited from this splendid isolation: quite the opposite. The absence of serious criticism has allowed a body of economic theory to develop that has extremely weak predictive, explanatory and descriptive power. Indeed orthodox economics may well have become the 21st century equivalent of the flat earth theory - something, incidentally, that many (astute) non-economists have known for a long time.
Occasionally, however, books come along that are not afraid to say `the Emperor has no clothes.' Tony Lawson's Reorienting Economics (significantly advancing the ideas of Economics and Reality) says just this. Because iconoclastic books like this challenge deeply ingrained habits of thought, they instil some people with a sense of anxiety, and are often dismissed with a range of rhetorical devices - especially in book reviews where cheap, and often superficial, shots can be passed off as good coin. The author is accused, variously, of failing to understand the technicalities of the subject, misunderstanding theorist X, failing to discuss theory Y or approach Z and so on. This seems to be the unfortunate response of some of the reviewers of Lawsons' books. No doubt Lawson does not understand everything, or everyone, and he certainly does not discuss every theory, theorist, or approach: but then again, who does.
What makes Lawson's work stand out is that he introduces the issue of ontology to the subject matter of economics. Ontology is the study of being; of the fundamental structure or components of a domain of reality; of the general kinds of things that exist. Lawson's books are concerned to elaborate the basic structure of the socio-economic domain specifically. His purpose is to draw out the implications of ontological theorising for all other forms of social theorising, including economics.
This, however, is not how orthodox economists proceed. Instead, they start with a kind of `off the shelf' fixed set of (mathematical) tools and simply presume, quite unreflexively, that it will be everywhere appropriate to socio-economic analysis. Lawson's argument is as clear as it is bold: this particular tool box is mostly inappropriate for investigating the socio-economic world and is certainly not of universal validity. Researchers in economics, typically, end up with a set of tools that predict, explain, and describe little or nothing about the way real (as opposed to fictitious) socio-economic practices actually work.
In Reorienting Economics Lawson urges us not to follow orthodoxy. Instead, he encourages us to embrace ontological investigation, that is, to proceed by enquiring into the way socio-economic reality is. And here economists have much to learn from other disciplines outside of economics - Lawson, in fact, refers to his oeuvre as `social theory.' We should strive to include in our tool box all those techniques that have the potential for uncovering, illuminating and explaining socio-economic phenomena. Following the path sketched in Lawson's books does not mean that we merely describe reality, but it does mean that we have to take the process of abstraction very seriously. Indeed Lawson is careful to differentiate legitimate abstraction from the illegitimate process of making knowingly false assumptions for no other purpose than making possible the deduction of outcomes from initial conditions. There is, of course, no guarantee that following Lawson's suggestions will lead to a solid understanding of socio-economic practices - there is an awful lot of work to be done to get from ontology to theory and practice. Yet the orthodox route, proceeding as it does on the basis of knowingly fictitious theories and models of reality, seems as the outset, doomed to fail.
If you suspect that orthodox economics lacks predictive, explanatory, and descriptive power, if you are interested in why this might be the case, and if you are interested in joining those heterodox economists engaged in the search for a plausible alternative, then Reorienting Economics (and Economics and Reality) should be on your bookshelf.
