Everyday the major financial newspapers and magazines provide Op Ed space to so-called leading economists. For the majority of the public, it is these Op Ed articles that provide their interaction with my profession. It is a pity. The majority of the reasoning presented by these characters, most who occupied senior positions in US academic departments, is spurious to say the least. The public is thus being poorly educated (to put it mildly) on a daily basis and this represents a major problem for our democracies. Voting in elections is one thing. But when citizens are voting based on faulty understandings that they have derived from these economists, then what is the value of a free vote? Today I consider the views of leading Princeton economist Alan Blinder – who is another macroeconomist who is blind to the way the economy works.

One of the puzzles that accompany this gruelling economic crisis is why neo-liberal economic thinking, which when applied caused the crisis and has delivered very little to so many, remains the dominant paradigm in economic policy making and has managed to turn a disaster for practitioners of that ideology into a triumph. How is it that the leading voices now are preaching exactly the same policies that caused the crisis as the solution to the crisis. Is there that much asymmetry? I noted a recent comment on my blog (Tom) that raised issues relating to the philosophy of science along the lines of how are we to judge whether the mainstream macroeconomics paradigm has failed. I understand the demarcation issues involved and the problems of “truth testing”. But we can take a more simple approach to the question. Here are two ways we know that the mainstream approach failed – they didn’t have a clue what was happening in the years leading up to the crisis and now they are scrambling in a stunned state to add banks and financial markets to their defective models. The problem is that they are just building more defective approaches. But the continued dominance demonstrates that their failures are not yet fully understood.

It is unsurprising that my profession has suddenly became enamoured with studies of financial cycles. Up until the GFC mainstream macroeconomics (theories and models) mostly ignored financial markets and banking, thinking that they were largely peripheral to understanding the business cycle. The only linkage between the financial sector and the real economy that was considered was via interest rates – the impact on investment spending and the demand for loanable funds to fund investment impacting back onto interest rates. Even within this limited context, the theories developed were hopelessly deficient and incapable of explaining anything that relates to the real economy. But now – more brash than ever – my profession is busily conjuring up financial markets to fit into their Dynamic Stochastic General Equilibrium (DSGE) models, despite these models being next to useless. In March 2009, Willem Buiter said that DSGE models “excludes everything relevant to the pursuit of financial stability.” More recent research from the BIS (link below in the text) has highlighted some salient facts about the relationship between financial cycles and business cycles. What that research implies is that push for fiscal austerity is without foundation and will not only damage the real economy but will, in the process, prolong the financial downturn and prevent a resolution that could provide the springboard for sustainable growth.

In yesterday’s blog – A nation cannot grow without spending – I challenged a view that dominates the European debate which says that fiscal austerity (choking discretionary net public spending) supplemented with vigorous so-called “structural reforms” (aka ransacking wages and working conditions) will promote growth. The corollary of this view is that fiscal austerity alone will fail and the reason Europe is going backwards is not because of the austerity but rather, because the structural reforms process has not been implemented quickly or deeply enough. In all of this there is a basic denial of the fundamental macroeconomic insight – spending equals output which equals income. An economy can only growth if there is spending (aggregate demand) growth. That requires a demand-side solution irrespective of the state of the supply side. Supply improvements might reduce the danger of inflation or improve the quality of output but people still have to purchase the output for growth and innovation to persist. A related argument is that fiscal stimulus aimed at fostering growth will cause inflation and be self-defeating. This view prevails in mainstream macroeconomics as taught in the universities of the world. Some mainstream economists do qualify this view and give conditional support to the fiscal stimulus solution by appealing to what they term the “liquidity trap”. This blog is about that argument.

The IMF released a working paper recently (January 2012) – Macroeconomic and Welfare Costs of U.S. Fiscal Imbalances – which purports to estimate the losses that the US economy will incur if the US government delays a major fiscal consolidation. The paper attracted a Bloomberg news headline (February 3, 2012) – How Reducing the Deficit Can Make Us Richer: The Ticker – which, in its own way provides an example of a dishonest piece of reporting. What has the IMF paper have to say about real world issues like real GDP growth, unemployment, underemployment etc? Answer: virtually nothing. It is an example of GIGO (Garbage In, Garbage Out) and confirms that my profession has learned very little (if anything) from its total failure to see the crisis coming or offer valid solutions. It also confirms that while the IMF leadership might be going around lately trying to sound reasonable (warning against austerity) the engine room of the IMF hasn’t changed direction at all. It is still pumping out indefensible rubbish, which then garner headlines and influence the policy debate to the detriment of the unemployed everywhere. The IMF consider humans to be a “continuum of infinitely lived agents normalized to one”. Which means this paper becomes Part 3 of my GIGO series.

Evidence is a lovely thing sometimes. Like the speck of blood on a bomber jacket that has finally convicted the racist killers in London, 19 years after the crime was committed. In a different way, economic data is continually flowing in that makes vocal elements in my profession look like idiots. The only question is how long will it take for the rest of the world to know that and for governments to stop being influenced by the opinions of these economists. Over the last few decades I have been compiling interviews and commentaries from leading economists so that I can compare their predictions with the evolving reality. Economists typically make categorical statements such as – rising budget deficits will push up interest rates and choke off private spending – and then buttress those comments with arcane models that were negated both conceptually and empirically years ago. Invariably, when the mainstream economists do make predictions or empirical statements they are invariably wrong and then it is interesting to see how they respond to the anomaly – the dance that follows to try to maintain the upper-hand in the debate. They typically respond by nuancing the issue. But there are also times when their predictions are unambiguously wrong and ad hoc responses (of the Lakatosian type) make them look even more stupid. Then they bury their head in the sand and go into denial mode and their ideology takes over. The best antidote to this sort of dogma is evidence.

I have noticed some discussions abroad that criticise Modern Monetary Theory (MMT) on the basis that none of the main proponents have ever actually worked on the operations desk of a central bank. This sort of criticism is in the realm of “you cannot know anything unless you do it” which if true would mean almost all of the knowledge base shared by humanity would be deemed meaningless jabber. It is clearly possible to form a very accurate view of the way the monetary system operates (including the way central banks and the commercial banks) interact without ever having worked in either. However, today, I review a publication from the Bank of International Settlements which dovetails perfectly with the understandings that MMT has provided. It provides a case for why we should abandon mainstream monetary textbooks from the perspective of those who work inside the central banking system.

Overnight, the US Bureau of Labor Statistics released their latest Mass Layoffs data (May 2011) which showed that the number of mass layoff events in May increased by 2 percent. Further, another month went by and the US national unemployment rate remained unchanged at (a very high) 9.1 percent. There is very little happening to reduce it and the omens are bad. Also yesterday the US Federal Reserve decided to keep interest rates on hold in the 0 to 1/4 per cent range indefinitely and the Congressional Budget Office (CBO) released its 2011 Long-Term Budget Outlook. The statements accompany the central banks decision by its Chairperson Ben Bernanke about long-run fiscal problems and the very aggressive message in the CBO Outlook suggest that the politicians will continue to retard the US economic recovery and lock millions into entrenched unemployment and poverty. The US leaders are sure making a mess of things and the advice they are getting is appalling. The omens are clear – aggregate demand growth is desperately required to attack unemployment. But the land of the free is sliding further into oppression – self-induced by its political class.

Everything is Greek today in the financial press. The number of commentators who are concluding that Greece has to exit the Eurozone are increasing. It is obvious and it is only the obsessive desire of the Euro bosses to preserve the interests of a few banks at the expense of the welfare of millions that is keeping the EMU together at present. If they stepped outside their mainstream straitjacket for a moment they would see that the ECB could guarantee all French and German bank assets at the stroke of a pen. This mainstream blindness comes out in all sorts of ways. The problem is that social science of which economics is a branch (yes I am in that school rather than placing economics in “business”) – suffers in relation to the other sciences because it is hard to pin down things given the lack of controlled environments. With human behaviour essentially shifting the mainstream economists can get away with all sorts of lies and deceptions most of the time because it is too hard to prove otherwise. But sophisticated analysis is really not necessary. Over the last two decades we have had some real-life experiments going on before our very eyes that allow us to see through the cant that is mainstream theory. How many more experiments do we need before my professional colleagues are totally discredited?
