Earlier this year I reported on what a wonderful Xmas all the Ricardian agents (consumers and firms) had enjoyed in the UK as a result of the government austerity program. Please read my blog – Ricardians in UK have a wonderful Xmas. It seems those “agents” just cannot get enough of it. Now, more than 15 months into the austerity program and with the cuts about to really bite, the British economy continues to go backwards. Our real world laboratory is providing priceless data upon which we can assess basic propositions that mainstream macroeconomics provides and which Modern Monetary Theory (MMT) contests. A nation cannot have a fiscal contraction expansion when all other spending is flat or going backwards. Britain is up against an impossible equation.
