General equilibrium — the art of denying the obvious General equilibrium is fundamental to economics on a more normative level as well. A story about Adam Smith, the invisible hand, and the merits of markets pervades introductory textbooks, classroom teaching, and contemporary political discourse. The intellectual foundation of this story rests on general equilibrium, not on the latest mathematical excursions. If the foundation of everyone’s favourite...

General equilibrium theory — still dead after all these years Raphaële Chappe has written a very interesting article about the value of general equilibrium theory, concluding in the following words: For a student of real world markets, general equilibrium theory appears strangely distant. It is not surprising that a highly abstract framework consisting of hyper-rational agents might be ill equipped to provide a sufficiently credible account of markets in...

Krugman’s models — squeezing out central ideas from Keynes The gist is that despite Krugman’s claims to the contrary, the analysis is not really Keynesian, at least in comparison to The General Theory, or GT.

The reality of how money is created Everything we know is not just wrong – it’s backwards. When banks make loans, they create money. This is because money is really just an IOU. The role of the central bank is to preside over a legal order that effectively grants banks the exclusive right to create IOUs of a certain kind, ones that the government will recognise as legal tender by its willingness to accept them in payment of taxes. There’s really no limit...

The real debt problem One of the most effective ways of clearing up this most serious of all semantic confusions is to point out that private debt differs from national debt in being external. It is owed by one person to others. That is what makes it burdensome. Because it is interpersonal the proper analogy is not to national debt but to international debt…. But this does not hold for national debt which is owed by the nation to citizens of the same...
