Reforming Global Finance: Don't Leave It to the Economists

Oh my friends, you would not know it, how like music this is to my ears:
“Reforming Global Finance: Don't Leave It to the Economists”!!
The chairman of Britain's Financial Services Authority argues that in the decades before the collapse of Western financial markets in 2007, too many economists were practicing a wrong-headed kind of economics. Their obsession with designing intricate mathematical models pushed moral, ethical and practical considerations too far into the background. It is high time for that to change.
In a short article in “theGlobalist” Lord Turner discusses some of these issues. Due to its significance to our understanding of what has gone wrong, I have reprinted it below for your keen interest.
Before you begin to read Lord Turner’s wise words, I want to share something coming from my heart with you. It saddens me that when about 15 years ago, I began to say very similar things to what Lord Turner is saying now, my so-called fellow academic colleagues accused me of having gone mad. They told me, if I carry on like this, talking about ethics, morality, philosophy, theology, spirituality, love, sympathy, empathy, trust, sustainability, love for Mother Earth and the common good, I better consider leaving the economics profession and perhaps become a priest or social worker, or joining the Salvation Army.
I am not bitter, whatsoever. I am only sorry that no body at that time took economists like me seriously. But, who said there is no justice in this world. (See more: http://gcgi.info/how-it-began )
And now, here it is: The Wisdom of Lord Turner“In the decades before the collapse of Western financial markets in 2007 and the resulting deep recession, too many policymakers, bankers and regulators were influenced by a brand of economics that was better equipped to design intricate mathematical models than to deal with moral, ethic and practical considerations. Adair Turner, head of Britain’s Financial Services Authority, says that needs to change.
Keynes famously wrote that "practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist."
It is essential that economics deal with human beings as they actually are rather than assuming the existence of a rational Homo economicus.
I suspect however that the greater danger lies not so much with entirely practical men or women exempt from any intellectual influence, as with the reasonably intellectual men and women who are employed in the policymaking departments of central banks, regulatory bodies and governments, as well as in the risk-management departments of banks.
These individuals are often well aware of intellectual influences, but tend nevertheless to gravitate to simplified versions of the dominant beliefs of establishment economists (who are still very much alive).
It is essential to continually seek to lean against that tendency. It is essential that economics deal with the real world as it is — and in particular with human beings as they actually are — rather than assuming the existence of a rational Homo economicus in order to make economic analysis more mathematically tractable.
In my view, robust thinking about economics must be based on the following three requirements.
First, it must not assume that additional income — above a certain level required to satisfy essential human needs — will necessarily increase utility or happiness, even if only to a marginally declining extent. Instead, we should concern ourselves with the mathematically and empirically imprecise but important issues of how happiness, welfare, utility and income are defined and related.
We may only have imperfect and judgmental techniques to measure success against ultimate objectives such as life, satisfaction and happiness. But we need to remember that these objectives, not income maximization by itself, are what we should be trying to achieve.
Second, the new economics must not assume that people participating in financial markets make rational assessments of future probabilities of potential outcomes. Instead, we should seek to understand how different people actually make decisions in different circumstances, given that human brains are endowed with instinctive elements.
Third, the new economics must accept the reality of unavoidable uncertainty. Much of the old-style economics is devoted to exploring the assumed expectations of economic agents, which are believed to be distributed around the objective probability distribution of future outcomes.
The new economics should recognize the importance of political, philosophical and ethical issues, to which mathematics is incapable of giving precise answers.
That, however, is what is called a philosophical category error, since no probability of future outcomes objectively exists. Therefore, we must accept that all economic and social developments are subject to an inherent, irreducible level of uncertainty.
No mathematical answers
The logical consequence of these requirements is that the new economics should recognize the importance of political, philosophical and ethical issues, to which mathematics is incapable of giving precise answers.
For example, there is no precise answer to the question "What is the optimal degree of inequality?" It is an issue of politics. Likewise, the case for the market economy — which has been predominantly presented in terms of income-maximization outcomes — should, as Amartya Sen says, be considered in terms of freedom as an end in itself.
As John Hicks (although himself a major figure in the development of mathematical and outcomes-oriented economics) has noted wisely, "The liberal principles of the classical 'Smithian' or 'Ricardian' economists were not, in the first phase, economic principles; they were an application to economics of principles which were thought to apply in a much wider field. The contention that economic freedom made for economic efficiency was no more than a secondary support."
A major deficiency of the current conventional wisdom is that it has focused increasingly — and almost exclusively — on this secondary support, instead of on ethical, moral and practical considerations. That is all the more surprising since increasing prosperity has made further improvements in economic efficiency less important to human welfare.
"There is nothing in economics," wrote the British economist Lionel Robbins, "which relieves us of the obligation to choose."
Too many policymakers and politicians — who at least thought they were drawing on the insights of economists — forgot or chose to ignore that fact in the several decades of applying conventional wisdom and believing in false certainties that led to the financial crisis.”
