‘Observation is theory-laden’ — fashionable philosophical rubbish Now our slogan is that observation is theory-laden … The slogan cannot be literally true. If anything is ‘theory- laden’ it cannot be observation but rather statements made on the basis of observation.

‘New Keynesianism’ — little new and nothing Keynesian Not that long ago, Paul Krugman had a post up on his blog discussing ‘New Keynesian’ macroeconomics and the definition of necoclassical economics: Most of what I and many others do is sorta-kinda neoclassical because it takes the maximization-and-equilibrium world as a starting point or baseline, which is then modified — but not too much — in the direction of realism … New Keynesian models are intertemporal maximization modified with...

Playing the blame game  [embedded content] David Silvester, who resigned from the Conservative Party over David Cameron’s same-sex marriage policy, has said gay marriage is to blame for Britain’s recent spell of bad weather in a letter to The Henley Standard. He wrote: “Since the passage of the Marriage (Same Sex Couples) Act, the nation has been beset by serious storms and floods.” Huffington Post Thank God for all these intelligent and unprejudiced conservative politicians …...

What mainstream economists are embarrassed to admit The true state of affairs is almost opposite of what Friedman makes it out to be when he ventures the opinion that “different predictions about the importance of so-called ‘economies of scale’ account very largely for divergent views about the desirability or necessity of detailed government regulation of industry and even of socialism rather than private enterprises.” Was there ever an economist who came to believe in either socialism or...
