Thomas Palley — The flimflam defense of mainstream economics



Thomas Palley takes on Paul Krugman, Simon Wren-Lewis and faux Keynesianism.
The essence of Keynes’ economics was the liquidity preference theory of interest rates and rejection of the claim that price and nominal wage flexibility would ensure full employment. New Keynesians abandon both. They replace liquidity preference theory with loanable funds interest rate theory and they use price and nominal wage rigidity to explain cyclical unemployment.

I have long argued that the new Keynesian nomenclature is a cuckoo tactic because it captures the Keynesian label while having nothing to do with Keynes, in a manner similar to the cuckoo which lays its eggs in other birds’ nests. In my view, it is better labeled new Pigovian economics since it relies on market imperfections and frictions, which were the hallmarks of Pigou’s economic thinking. That makes for bitter irony as Pigou was Keynes’ greatly respected intellectual opponent in the 1930s and his thinking now passes under the Keynesian banner, displacing Keynes’ own ideas.
