The Microfoundations Delusion

Book excerpt: ïThis excellent book documents the creation of what has become the first commandment of orthodox macroeconomics: that microeconomic theory provides its foundation because this is the most secure form of economic knowledge. By contrast, John King shows conclusively that microeconomics cannot play such a role when assessed by the criteria of logic, or of science, or of economics itself. Indeed, he goes further and demonstrates that the microfoundations dogma detracts from knowledge about how economies actually operate, and instead generates patently false conclusions. Moreover, the dogma is shown to have blinded orthodox economists from even seeing the possibility of typical macroeconomic crises, and has disarmed them in formulating policies that would eliminate actual crises. The book therefore deals with a topic at the very heart of the present debacle in the world economy.Í _ Michael Howard, University of Waterloo, Canada ïA generation ago Dudley Dillard wrote a famous article on the ñbarter illusion in classical and neoclassical economicsî. Now John King has gone a step further and written about the microfoundations delusion. The illusion has been with us for a very long time, the delusion is of more recent vintage. Together they have blocked a basic understanding of macroeconomic and monetary phenomena at a time when they are most urgently needed. This is a book that had to be written, and we are fortunate that it is John King who has written it. Essential reading for our times.Í _ John Smithin, York University, Canada In this challenging book, John King makes a sustained and comprehensive attack on the dogma that macroeconomic theory must have ïrigorous microfoundationsÍ. He draws on both the philosophy of science and the history of economic thought to demonstrate the dangers of foundational metaphors and the defects of micro-reduction as a methodological principle. Strong criticism of the microfoundations dogma is documented in great detail, from some mainstream and many heterodox economists and also from economic methodologists, social theorists and evolutionary biologists. The author argues for the relative autonomy of macroeconomics as a distinct ïspecial scienceÍ, cooperating with but most definitely not reducible to microeconomics. The Microfoundations Delusion will prove a stimulating and thought-provoking read for scholars, students and researchers in the fields of economics, heterodox economics and history of economic thought.
