The so-called “Washington Consensus” ought to have been consigned to the scrapheap of history by now. The consensus – sometimes known as neo-classical economics – underpinned macroeconomic policy, including financial (de)regulation and central bank policy, for most of the past three decades. But the Panglossian assumptions about financial markets that underpinned ultimately gave rise to the global financial crisis from which many economies have yet to recover.

So why do so many people – including global leaders who still believe the best way to promote recovery in massively over-leveraged and bankrupt economies is to inject further leverage – adhere to this intellectual wrong-headedness?

It seems that a great many people – business and finance, the media, economics faculties, politics, and government – just want an easy life. Most are thinking about the short term, towards the next election or annual results presentation, and a change of 'religion' might imply deeper short-term pain. At a country level this sort of thing has traditionally required revolutions and bloody civil wars.Perhaps they just feel safer thinking along similar lines as before (albeit perhaps with a bit of austerity and fiscal rectitude thrown in) in the hope that things will just keep chugging along until they retire?

The BBC documentary maker Adam Curtis summed up the situation in a recent blog called The Curse of TINA:

Professor Richard Werner, director of the Centre for Banking, Finance and Sustainable Development at the University of Southampton, has described the bizarre intellectual contortions 21st century economists must go through in a viewpoint published in the first edition of QFINANCE in October 2009. Werner wrote:

I won’t summarize Professor Werner’s entire piece here, but he concludes with several entirely workable recommendations including that private sector banks should be relieved of their credit creation responsibilities. We need more people like Werner to help us identify the big weaknesses in neo-classical economics (sometimes also known as neo-liberalism) and to suggest workable alternatives.

So when did the rot set in? Russell Napier, a consultant for CLSA Asia Pacific Markets and founder of the Practical History of Financial Markets course, believes the real “intellectual disaster” took place in the 1960s. It was then that economists with high ambitions for their profession found a way of transforming what had been at best a social science into a 'hard' science. Napier believes that economists and policymakers’ faith in the market’s superior ability to allocate resources became entrenched because the state had done this so spectacularly badly in the post-World War Two years.

Gradually this morphed into the widespread belief that fictions like “perfect markets” and Eugene Fama's “efficient market hypothesis” were real. And it wasn't long before groupthink set in. Neo-classical economic thinking became entrenched inside finance ministries, economics departments, banks and other financial institutions. Alan Greenspan was one of its high priests, and Britain's Labour Prime Minister Gordon Brown one of his most ardent disciples.

Then, as Napier writes (his viewpoint is published in the third edition of QFINANCE and already available online courtesy of Quantum Magazine) having built our financial system on what turned out to be fraudulent intellectual foundations (i.e. sand), the whole thing was damn near swept away in the global financial crisis of 2007-09.

One of the most tragic and perturbing things about all this, also emphasized in a viewpoint by the prominent reformist chartered accountant Richard J Murphy, is that university economics and finance departments became one-party states – and remain so despite the bankruptcy of their ideas. No one who is not willing to worship at the shrine of neoclassical economics, or who is not willing to pretend to do so, had much chance of becoming an economist in the UK at the moment. 

It's depressing. Clearly there's a huge appetite for alternative approaches to economics right now, especially ones that are empirical and rooted in the realities of the world and how it actually works. Unfortunately, however, the prevailing orthodoxy means that proponents of such alternative models invariably struggle to get funding, and some struggle to get a fair hearing. Some are marginalized as "pinkos" and "lefties".

But there again there are signs of hope. People who are prepared to break out of the confines of neo-classical thinking were arguably given real impetus by the global Occupy movement which kicked off in New York's Zuccotti Park last September.

My own, far from exhaustive, list of people and organizations who are working towards the discovery of more sustainable economic models includes Nouriel Roubini, Steve Keen, Ha-Joon Chang, Yves Smith (main author of the Naked Capitalism blog), the Capital Institute, the Institute for New Economic Thinking, the New Economics Foundation, and the US investor Jeremy Grantham. Such themes have also been comprehensively addressed in Financial Times’ Capitalism in Crisis series and by Richard Murphy in The Courageous State.

With the widespread ostrich-like tendency in high places and, in the light of the eviction of Occupy, there is a danger that the search for more sustainable ways of organizing economies might lose steam. We must not let this happen.
