Indeed, plenty of criticism of econom...Dear Simon,<br /><br />Indeed, plenty of criticism of economics is rather misplaced, and uninformed and much of the best critical literature in economics comes from inside the profession. But: <br /><br />(1) There remains a remarkable degree of dogma amongst (some) macroeconomists. Indeed, you make the point yourself with your remarks about the microfoundational ayatollahs. I well remember the dogmas I came across as a student. Robert Lucas claiming that only macro models based on rational maximising agents could constitute science. Or Friedman’s 1953 essay on positive economics, which so many economists seem to have taken to heart (who cares if your assumptions are wildy at odds with reality, if you can adequately replicate your chosen data). Or the dogma that economics is a science, when so many conclusions in economics are contingent, there are no immutable laws, and predictive power is often poor.<br /><br />(2) You equate “pluralism” with “picking your own conclusions”. Looks like a strawman to me. The point is surely that pluralism in methods can be valuable. Different schools frequently adopt differing underlying views on methodological issues, this leads to different approaches, which can generate different insights.<br /><br />For example, there is a splendid review essay by Mark Setterfield where he reviews the (now fairly old) Grossman/Helpman book on endogenous growth and innovation, and compares the approach taken with that in a book by business historican Bill Lazonick. It is available online. I personally think both books contain approaches that are perfectly valid research strategies, and may lead to different insights. Yet I suspect many would dismiss the Lazonick material as “not economics” (no formal model, you see).<br /><br />(3) You accept that economists “made a mistake” in the 1980s by limiting the choice of acceptable models. Indeed. And they still do. Maybe it is unfair to point too much to textbooks, but frankly, many are little better than brainwashing.If you doubt me, have a look at the Blanchard/ Giavazzi book on European Macroeconomics. The chapter on growth theory basically says that the Solow framework is how economists (implicitly ALL economists) analyze growth. No discussion of Smith, Schumpeter, Lewis, Hirschman or anyone else. <br /><br />At a rather different level, take a look at the BIS working paper by Borio and Disayat on the current account (working paper 525). They make a completely convincing case that many macroeconomists continue to confuse saving and financing, and that this underlies the persistence of several so called paradoxes in economics ( eg the Lucas paradox, the Feldstein Horioka problem). In short, the conventional wisdom can be flat wrong.<br /><br />Or consider the way trade unions and industrial relations fit into economic literature. I struggled as an undergraduate to square the widespread view in economic texts that unions are a “market distortion” with the rather obvious fact that some countries with remarkably strong trade unions seemed to manage very well indeed. It was only sociologists like Alan Fox, or Wolfgang Streeck, or the literature on development of firms (Penrose, Best etc), that I understood what was missing from the standard textbook models. <br /><br />(4) In essence, I really do not see economics as a science in the sense that we edge closer to the immutable truth. We can edge towards “right” answers to quite specific questions, but those truths may not be consistent in time or place. I prefer to see it as a toolkit for analysis - a set of models, theories and literature that we can apply to specific questions. But what models or approaches are relevant or useful depends on the precise question being asked. This is why economists need to be exposed to different perspectives - to learn to compare, contrast, and think deeply about implicit assumptions. That is also why I call myself a pluralist (but would strongly dispute that I am a relativist)rjwhttps://www.blogger.com/profile/02712012011664175472noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-73005336783128293362018-01-12T17:24:31.065+00:002018-01-12T17:24:31.065+00:00Simon,

But I do think that on this topic you ignore the public face of economics. <br />After the Global Financial Crisis, which was predicted by very few economists of note, the highest-profile advice came from pro-austerity economists. <br />In the public sphere, there was a notorious letter to The Times, signed by (among others) Tim Besley, London School of Economics; Sir Howard Davies, London School of Economics; Charles Goodhart, London School of Economics; Lord Turnbull, London School of Economics; Sir John Vickers, Oxford University; Ken Rogoff, Harvard University; and Roger Bootle, Capital Economics. <br />The two highest-profile academic at the time papers were Large Changes in Fiscal Policy: Taxes Versus Spending by Alberto F. Alesina & Silvia Ardagna which supported spending cuts and tax cuts as fiscal stimulation rather than public spending increases, and Growth in a Time of Debt by Carmen M. Reinhart and Kenneth S. Rogoff which claimed that countries with debt to GDP ratio over 90% were likely to experience significantly reduced long-term growth.<br />Unless my recollection is distorted, this letter – even though contradicted by a later letter in The Financial Times – and these two papers dominated policy discussions. If the economics profession was not in favour of austerity, it did not come across to the public.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-17995819853875697032018-01-12T00:16:28.597+00:002018-01-12T00:16:28.597+00:00"Economics, even though it is a social scienc..."Economics, even though it is a social science, should conform to the scientific method"<br /><br />Talk about the "scientific method" generates nothing but useless verbiage. There isn't anything special about reasoning in science except that it's more careful than is usual in ordinary conversation. <br /><br />There is an extensive literature in Philosophy of Science about this. You might want to start with the essay "Two Dogmas of Empiricism" by W.V.O. Quine. Depressingly, this was first published in 1951.<br /><br />What's done in science is to argue tightly and to try hard to be correct. This is excellent practice.<br /><br />Before dismissing criticisms of economics for being intrinsically value-laden you might wish to read "The End of Value-Free Economics" by Hillary Putnam. Putnam is famous in philosophical circles, although not anywhere else. (Parenthetically, the criticisms of economics you cite are in my experience perhaps even more wrong-headed than claims of clear separation between the positive and the normative). At least after that you'll be clearer on the real philosophical issues involved.<br /><br />I should add that I very much like your blog. The quoted phrase just pushed one of my buttons.inquirerhttps://www.blogger.com/profile/17712708265810814971noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-57774794016739040822018-01-11T11:00:55.286+00:002018-01-11T11:00:55.286+00:00The EU Commission, using information from economis...The EU Commission, using information from economists, warned the Irish repeatedly in advance of the collapse of the Irish banks that the economy was overheating and that it needed to rein in pro-cyclical policies. It was robustly advised what to do with its advice by then finance minister, Charlie McCreevy, famous for his "when I have it, I spend it" approach and for narrowing the tax base to depend on unsustainable revenues from the property bubble. He was loudly cheered by a public drunk on illusory wealth.<br /><br />Then the day of reckoning came and the EU and the economists were vindicated and people learned some lessons the hard way, because they had insisted on it. Of course, the government was to blame for having guaranteed the bank debts without having known, truly, the scale of them. And that mattered considerably more than who was right.<br /><br />Awareness of the counterfactuals is one thing (and the public has been assailed by a media which delights in finding experts who disagree, leading it to skepticism about expertise generally instead of vested interests), social memory another. The German memories of inflation and the Irish of hunger had lasted and remain consequential, affecting attitudes to what is right (Ireland spends more of its GDP on social transfers than any other OECD country). <br /><br />The UK hasn't had to face traumatic adversity and has been free to believe that that is the natural order of things. A complacent public that can be lied to with impunity by, e.g., David Cameron going to town with Liam Byrne's "no money left note", is hardly going to critically assess and keep score of the work of economists. In a world where the 0.001% rule we are all disgraced by our inability to hold them to account, not just the economists who do not perform for loose change (see the introductory part of the film "An inside job" for some choice examples). <br /><br />Worrying about the credibility of economists now is like someone with heart disease being concerned with a minor injury. Our societies face threats far more important than the business cycle's unpredictability. We have to deal with information pollution and the financing of politics with some of the rigour applied to airline safety (economies, democracies and peace matter even more). I can't recommend enough the article on Facebook in the latest Washington Monthly. When people can't distinguish truth in a market rigged for lies we are all lost, economists, good and bad, included.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-53578664941622399732018-01-11T07:10:36.829+00:002018-01-11T07:10:36.829+00:00An indulgent post.

Really mainstream economists had a role in the financial crisis, Brexit, trump, and continued and growing instability in Africa and the Middle East. You had your eyes off the ball during what you called the Great Moderation when there were deep problems with capitalism. And we are seeing the political fallout. Rather than look at what was going on, and perhaps build on the work of Kalecki, Polanyi, Schumpeter and Keynes, you chose to mess around with DSGE, RBC, ISLM, and stochastic tests. The response to the crisis was a partial success and gave us a temporary respite - but these unconventional monetary policies and there design were no thanks to anything in that anybody came up with in post-Samuelson economics.<br /><br />The behaviour of economists is rather like bankers, who were fooled by their models (or perhaps they weren't - but they thought there would be too much at stake to abandon them).<br /><br />NK.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-36088393474340528412018-01-10T20:03:43.042+00:002018-01-10T20:03:43.042+00:00"It is dangerous if it suggests that economis..."It is dangerous if it suggests that economists should be encouraged to base their analysis on assumptions that reflect their values. Economics, even though it is a social science, should conform to the scientific method: it should be as much like a science as medicine."<br /><br />The word "should" is often the primary clue that one using normative rather than non-normative descriptive language. The use of normative language implies normative evaluations in the minds of the language-users. It is exceptionally difficult to do science or any other endeavor without performing evaluations that are normative. The question is whether consensus is reached in those evaluations by a large group of earnest practitioners or whether reasonable minds would disagree when making personal evaluations?<br /><br />For example in law homicide is defined as the act of killing another person. To prove murder the prosecution must convince the jury that the defendant did, indeed, commit an act of homicide, as an element of the case. If the process of evaluating facts and evidence itself normative or can it be considered as a non-normative evaluation process involving mere factual reasoning? In any event homicide is not considered a crime in itself because, as a normative rule, society does not punish someone for events beyond his or her control (e.g., having an unpredictable seizure while driving that results in homicide) or certain acts in defense of self or others (called justifiable homicide). Murder is defined by the intent to kill another with malice and we even punish the act of planning a murder if intent can be proven.<br /><br />So my question is "should" the soft or social scientists pretend to be more scientific than they really can be? The answer is "no" because to say the "should" is really just saying that social scientists want to be like the more empirical sciences that they imitate in much the same way that a child might want to be like a parent or authority figure they admire and who gains prestige in society. Thomas Szasz, who wrote The Myth of Mental Illness, says that there is no such thing as mental disease except in the normative judgment of the community of mental health workers, just as there is no such thing as murder except in the normative judgment of the human community, but there is such a thing as natural disease or medical disability which doctors can learn to recognize and treat via non-normative reasoning. Of course the desire to recognize and treat medical disease (or mental disorders or political-economic problems) occurs in a web of normative evaluations (health and well-being are good, disease, disability, and death are bad).Joe Leotehttps://www.blogger.com/profile/01292763300917387201noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-86502325467977114862018-01-10T17:07:45.133+00:002018-01-10T17:07:45.133+00:00Seems like a consensus could be reached somewhere ...Seems like a consensus could be reached somewhere around the idea that, in our present circumstance, powerful economists are useless, and useful economists are powerless.Michael Rhttps://www.blogger.com/profile/10045827917076142231noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-53747372783320428232018-01-10T13:12:47.992+00:002018-01-10T13:12:47.992+00:00The reason economist take such stick is the media ...The reason economist take such stick is the media and politicians can hide there ideology behind economic theory even when its been proven wrong! the assumption economist make aren't always true (take pricing) and the maths is bad ie 1% pay 27% of all tax is taken completely out of context because it only uses a part of the equation not all of it, 1% own about 90% of the wealth and pay 27% of the tax on that wealth,so 105 of the wealth,99% of the population pay 73% of the tax burden! to attack this deliberate narrative to hoodwink the population,you don't just have to destroy the messenger or those that impose such silly narratives which we the people see everyday without undermining the theory because ,we the public don't get to actually see economist like you on question time or daily politics to put the record straight,you need a platform on McDonell gave you economist to be at the heart of influencing policy making and one that was deliberately destroy,you still need a platform to distance yourselves from quack quack flat earth interpretation of economic theory and work to create capitalism in equilibrium because the IEA,ASI,TPA are destroying you're credibility quicker than you can build it! paulhttps://www.blogger.com/profile/03431327179470830789noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-30898474310324020832018-01-10T11:01:56.353+00:002018-01-10T11:01:56.353+00:00This comment has been removed by the author.jerred seiysllhttps://www.blogger.com/profile/17375770046164311780noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-18270177261394231492018-01-10T10:25:19.887+00:002018-01-10T10:25:19.887+00:00Say I'm a math major, but I take an econ class...Say I'm a math major, but I take an econ class in college.

Many of these answers may lie in the austerity question but focussing on the economic rationale for austerity rather than its implication is perhaps where economists are going wrong?Michaelhttps://www.blogger.com/profile/02437021798517785745noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-43187396559920099072018-01-10T09:15:47.542+00:002018-01-10T09:15:47.542+00:00Economics may be most influential because of its p...Economics may be most influential because of its performative picture of social reality (hidden agenda), NOT its advice (overt agenda).<br />Compare:<br />- “The ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood.<br />Indeed the world is ruled by little else.” (John Maynard Keynes)<br />- “I don’t care who writes a nation's laws,<br />if I can write its economics textbooks.” (Paul Samuelson)<br />That implies that most of the normativity & political responsibility of economics may be due to that performativity (its picture of reality making itself true).<br />Claiming economics is like medicine disempowers people (it pictures them and thus makes them into 'unaware cells' when they behave accordingly because they are told on the authority of economists and those that lend their ideas that they have no alternative).Wim Nusselderhttps://www.blogger.com/profile/07997282141403874498noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-28527826776643835782018-01-10T05:35:29.391+00:002018-01-10T05:35:29.391+00:00I agree many criticisms of economics is unjustifie...I agree many criticisms of economics is unjustified. At the risk of adding yet another unjustified criticism, I think economists on the whole pay insufficient attention to distributional concerns. I did a whole undergraduate degree in economics without having learnt any of the work (of Atkinson, Sen, etc) about distributional concerns and social justice. In the postgraduate courses (not PhD), there were no courses offered that covered distributional issues and social justice. One gets the impression that distributional issues are not a matter for economics. <br /><br />Economists ought to include distributional issues and social justice in their programs, particularly if they go on to become involved in policy making.

There were books, television series, tracts and presentations. There was a pavilion at the 1964-1965 World's Fair in New York, for example. Many of the public advocates were, in fact, economists arguing against state intervention, against regulation, against taxation and so on. Their message resonated with that of right wing politicians whose fortunes rose with this concerted campaign.<br /><br />The campaign was successful. We are in a fine mess, as most economists expected we would be. The public remembers that propaganda push and the economists behind it. Just as they expect a scientist to wear glasses, they expect an economist to spout what most economists would consider right wing nonsense.<br /><br />The only answer I can think of is a counter-propaganda push, but it would be hard to fund this given our modern corporate overlords.Kaleberghttps://www.blogger.com/profile/05283840743310507878noreply@blogger.comtag:blogger.com,1999:blog-2546602206734889307.post-82351886666781823272018-01-09T19:42:22.121+00:002018-01-09T19:42:22.121+00:00Important that you insist economics is like medici...Important that you insist economics is like medicine.
