It is remarkable that the International Monetary Fund, one of the bastions of our modern economic construct, should be so willing to test and challenge current economic thinking. But that is what it does in publishing a striking short blog by respected economist Angus Deaton. Deaton is best known for his remarkable work on the US epidemic of what he has dubbed deaths of despair and he also led a recently-completed eponymous review of inequality for the Institute of Fiscal Studies. Deaton offers what amounts to an apologia for modern economics, and suggests some routes that may be more productive for the future. Not only might they be more productive, I would suggest that they are also likely to be fairer.
In the blog, Deaton questions mainstream economics. He does so from a remarkably mainstream position. He won the Nobel Prize in 2015, and is a professor at Princeton. His criticism of the failings of current economics, and not least of current economic education, should therefore hit home.
The core of Deaton’s points are made in crisp discussions under a handful of bullet-point headings. These are: power, philosophy and ethics, efficiency, empirical methods and humility (doesn’t our entire world need a whole lot more of that last?). He comes most crisply to his point in the first of these: “Without an analysis of power, it is hard to understand inequality or much else in modern capitalism.” But the bullet points reflect a continuity of thought, not separate ideas. He complains at the loss of ethical thought from economics and its replacement by an emphasis on efficiency and a simplifying focus on the financial: “We often equate well-being with money or consumption, missing much of what matters to people.”
Under efficiency, he states:
“Many subscribe to Lionel Robbins’ definition of economics as the allocation of scarce resources among competing ends or to the stronger version that says that economists should focus on efficiency and leave equity to others, to politicians or administrators. But the others regularly fail to materialize, so that when efficiency comes with upward redistribution—frequently though not inevitably—our recommendations become little more than a license for plunder.”
I think that quote bears rereading.
Applying these five approaches as a new lens for approaching questions, Deaton reaches a range of fresh conclusions – or rather a reduced level of certainty – about a number of different issues. These include: unions, free trade, global poverty and immigration.
But though it is not among these bullet-points, or the issues about which Deaton now has less certainty, to my mind one of the most notable single words in the piece is ‘efficacy’. Deaton says: “today we [economists] are in some disarray. We did not collectively predict the financial crisis and, worse still, we may have contributed to it through an overenthusiastic belief in the efficacy of markets, especially financial markets whose structure and implications we understood less well than we thought.” Normally economists and investors talk about market efficiency, and certainly the financial crisis was in part due to overconfidence that markets are efficient, that they will find the right prices for things. The efficient market hypothesis – which many investors take as a certainty, even though it is merely an hypothesis, and even though there would be no ability of active investors to outperform if it were true (admittedly many are more lucky than genuinely generate outperformance, but nonetheless it is still possible to outperform a market). The crisis showed that market pricing can often be very wrong and the use of market prices as a foundation for valuations can be risky.
Deaton is clearly referencing the Efficient Market Hypothesis (and the use of ‘efficiency’ as one of his bullet-point headings makes more notable his decision not to use the term in his comment about the disarray of modern economics), but he is actually making a very different point. He is asking whether markets are always efficacious, whether they work and always add value to human society. And his clear view is that they are not always, and do not always. We should listen, particularly those of us who work in financial markets.
Deaton has never minced his words, but here he is remarkably cruel about his profession. He says he does not want to get into the question of corruption among his peers, though he notes that allegations “have become common in some debates”. But he does state, bluntly: “economists, who have prospered mightily over the past half century, might fairly be accused of having a vested interest in capitalism as it currently operates”. In a blog that clearly has real concerns about the operation of modern capitalism, that fair comment is one that should hang over the profession, challenging all to rethink with the confidence and honesty that Deaton has.
