Was Adam Smith an economist? Was Keynes, Ricardo or Schumpeter? By the standards of today’s academic economists, the answer is no. Smith, Ricardo and Keynes produced no mathematical models. Their work lacked the “analytical rigour” and precise deductive logic demanded by modern economics. And none of them ever produced an econometric forecast (although Keynes and Schumpeter were able mathematicians). If any of these giants of economics applied for a university job today, they would be rejected. As for their written work, it would not have a chance of acceptance in the Economic Journal or American Economic Review. The editors, if they felt charitable, might advise Smith and Keynes to try a journal of history or sociology.

But in general how many academic economists have had something useful to say about the greatest upheaval in 70 years? The truth is even worse than this rhetorical question suggests: not only have economists, as a profession, failed to guide the world out of the crisis, they were also primarily responsible for leading us into it.

Neither do I mean the forecasters whose computer models churn out scientific-looking numbers on future growth or inflation, numbers that have to be revised so drastically whenever something “unexpected” happens (as it always does) that they are not really forec…
