For decades, mainstream economists have reacted to criticism of their methodology mainly by dismissing it, rather than engaging with it. And the customary form that dismissal has taken is to argue that critics and purveyors of alternative approaches to economics simply aren’t capable of understanding the mathematics the mainstream uses. The latest instalment of this slant on non-mainstream economic theory appeared in Noah Smith’s column in Bloomberg View: “Economics Without Math Is Trendy, But It Doesn’t Add Up“.
A cliché—“Expect the Unexpected”—has happened. As I noted in “The Divisive Brexit Vote”, though I favoured Brexit, I took the opinion polls at face value, and expected that Britain as a whole would vote to remain in the EU. Instead, in the largest electoral turnout in twenty years, the UK voted 52:48 in favour of leaving the EU.
I’ll leave a post-mortem of the vote itself for later; the main interest now is what will happen because of it. Many pundits from the Center, Left and Right opposed Brexit in the belief that economic Armageddon for Britain and the globe would flow from it; we’ll now see how realistic their fears were. I regard them as seriously overblown, for a number of reasons.
Andrew comments that he broadly agrees with my economic analysis on most issues, but vehemently opposes me here. Likewise, good friends like the heterodox economist Geoffrey Hogdgson; Ann Pettifor, who led the successful Jubilee 2000 campaign to cancel the debt of the world’s poorest nations; and Yanis Varoufakis, who knows a thing or two about the EU, all strongly support Remain.
Note: This was published as my last column on Business Spectator on April 6th, but it’s now gone missing after News Ltd merged BS with its own in-house stable and changed all the URLs. Given the election and Elizabeth Farrelly’s excellent thought piece in the Sydney Morning Herald “The great tragedy of Malcolm Turnbull“, I thought it was a good time to revive it.
One of the disadvantages of growing up is finding in your old age that people you never took seriously in your youth are now running your country.
CERN has just announced the discovery of a new particle, called the “FERIR”.
This is not a fundamental particle of matter like the Higgs Boson, but an invention of economists. CERN in this instance stands not for the famous particle accelerator straddling the French and Swiss borders, but for an economic research lab at MIT—whose initials are coincidentally the same as those of its far more famous cousin.
Despite its relative anonymity, MIT’s CERN is far more important than its physical namesake. The latter merely informs us about the fundamental nature of the universe. MIT’s CERN, on the other hand, shapes our lives today, because the discoveries it makes dramatically affect economic policy.
Using the dynamics of credit–which most other economists ignore–I explain why Japan, the USA and UK are among the “Walking Dead of Debt” and why China, Canada, Australia and South Korea are on their way to joining the Debt Zombies. This presentation is based on work I’m doing for a new 25000 word book for Polity Press entitled “Can we avoid another financial crisis?”, which should be published later this year.
The Lucas Critique has ruled economics for the last 40 years, and led it into a dead-end as well. In this talk to the Economics for Everyone conference run by the Post Crash Economics Society in Manchester, I argue that micro-founded models fail because of the emergent properties that characterise complex systems. An alternative approach that transcends Lucas’s well-founded objection to ad-hoc model-building is to build models from strictly true macroeconomic identities. I show that three simple identities–the employment rate, the wages share of income, and the private-debt-to-GDP ratio–are sufficient to build a simple dynamic model that generates the possibility of a financial crisis. I also give a high-speed but I think comprehensible tutorial on using Minsky, the Open Source monetary modelling program.
