Axel Leijonhufvud In Memoriam I first came across Axel’s writing as an undergraduate student at Manchester University where we were taught from his doctoral dissertation, Keynes and the Keynesians; a book that shot Axel to intellectual rock stardom. He argued in that book that Keynes’ General Theory had nothing to do with sticky wages and prices but was instead about inter-temporal coordination failure … Although Axel recognized the importance...

The orthodox Keynesianism of the time did have a theoretical explanation for recessions and depressions. Proponents saw the economy as a self-regulating machine in which individual decisions typically lead to a situation of full employment and healthy growth. The primary reason for periods of recession and depression was because wages did not fall quickly enough. If wages could fall rapidly and extensively enough, then the economy would absorb the unemployed. Orthodox...

What guarantee is there … that economic concepts can be mapped unambiguously into mathematical concepts? The belief in the power and necessity of formalizing economic theory mathematically has thus obliterated the distinction between cognitively perceiving and understanding concepts from different domains and mapping them into each other. Whether the age-old problem of the equality between supply and demand should be mathematically formalized as a system of inequalities or...

In 1990, two economics PhD students at the University of Chicago, Jeffrey Smith and Kermit Daniel … composed “Economics to Sociology Phrase Book” in order, as they put it, “to help economists adjust their way of speaking in a manner that will make it comprehensible to Sociologists” … Concerning economics terminology, by the way, one can see that not much has changed since then.

A couple of years ago, Paul Krugman had a piece up on his blog arguing that the ‘discipline of modeling’ is a sine qua non for tackling politically and emotionally charged economic issues: In my experience, modeling is a helpful tool (among others) in avoiding that trap, in being self-aware when you’re starting to let your desired conclusions dictate your analysis. Why? Because when you try to write down a model, it often seems to lead some place you weren’t expecting or...

My latest book has recently been published by Edward Elgar. The book explores the impact of neoliberal policies on the US, Europe, and the global economy. It shows how the 2008 financial crisis and Great Recession were predictable outcomes of the neoliberal policy experiment, as is the emergence of global “race to the bottom” competition. […]

On mathematics and economics Studying mathematics and logic is interesting and fun. It sharpens the mind. But economics is not pure mathematics or logic. It’s about society. The real world. Forgetting that, economics becomes nothing but an irrelevant and uninteresting ‘Glasperlenspiel.’ Or as Knut Wicksell put it already a century ago: One must, of course, beware of expecting from this method more than it can give. Out of the crucible of calculation comes...
Read More »The main insight of MMT
The main insight of MMT MMT is, first and foremost, a balance sheet approach to macroeconomics. At its very core lie reserve accounting, then deposit accounting, and then sectoral balances accounting. There is very little behaviour in any of this. Equilibrium rules as all balances balance – in both flows and stocks – and there are no assumptions apart from the existence of a central bank, a Treasury, a banking system and some households and firms. MMT can...

Has economics — really — become an empirical science? In Economics Rules (Oxford University Press, 2015), Dani Rodrik maintains that ‘imaginative empirical methods’ — such as game theoretical applications, natural experiments, field experiments, lab experiments, RCTs — can help us to answer questions concerning the external validity of economic models. In Rodrik’s view, they are more or less tests of ‘an underlying economic model’ and enable economists to...
