The debt delusion

For at least a few moments this week, President Trump suggested a payroll tax cut to stimulate the stalling macroeconomy. Although it appears that he has already changed his mind, it’s worth taking a look at the strategy...just in case.
Let’s say for sake of argument that the negative signals we have received of late are accurate. What should we do if we slip into full-fledged recession? Cut interest rates? Lower the budget deficit? Decrease payroll taxes? It turns out that the last one is the clear and easy winner. Why?Forbes — Pragmatic Economics
I think the very smart Jeffrey Friedman gets this… not quite right. The case for the empirical benefits of capitalism is very strong—but only if one is willing to remove libertarian blinders and focus on eliminating the market failures (in distributions, in aggregate demand, in externalities, in information, etc.) that keep the function the market maximizes from being a good proxy for societal well-being. And once one has the market properly supported and disciplined, the philosophical discussion can commence: Jeffrey Friedman: What’s Wrong with Libertarianism: “Libertarian arguments about the empirical benefits of capitalism are, as yet, inadequate…From the Marxian and Institutionalist points of view, economic liberalism, of which contemporary Libertarianism is a variant, provides the philosophical framework for bourgeois capitalism. Its fundamental weakness is prioritizing economic liberalism over social and political liberalism, which gives rise to many paradoxes of liberalism that result in illiberality such as have been pointed out many time here at MNE.
But, above all, individualism, if it can be purged of its defects and its abuses, is the best safeguard of personal liberty in the sense that, compared with any other system, it greatly widens the field for the exercise of personal choice.Individualism as the pursuit of self-interest does not lead to the greatest good for the greatest number the spontaneous emergence of natural order, unless "natural order" is conceived as the outcome of social Darwinism. This result is so grossly unfair that overtime it becomes unstable politically.
A key purpose of demand-led growth theory is to extend the ‘principle of effective demand’ to contexts in which productive capacity is best considered variable rather than fixed. The central idea is that, over any time frame, it is demand that determines output, and demand-led variations in income that adjust planned leakages to planned injections. Once it is acknowledged that capacity is variable, it becomes clear that the adjustment of output to demand, and planned leakages to planned injections, can be achieved not only by utilizing existing capacity more fully, but by expanding capacity through investment....heteconomist
There is a psychological bias to believe that exceptional events eventually give way to a return to “normal times.” But the world economy is far from a return to pre-2008 normality, with most of the obstacles to more robust recovery to be found on the demand side.Project Syndicate
Milton Friedman and his gang at Chicago, including the ‘boys’ that went back and put their ‘free market’ wrecking ball through Chile under the butcher Pinochet, have really left a mess of confusion and lies behind in the hallowed halls of the academy, which in the 1970s seeped out, like slime, into the central banks and the treasury departments of the world. The overall intent of the literature they developed was to force governments to abandon so-called fiscal activism (the discretionary use of government spending and taxation policy to fine-tune total spending so as to achieve full employment), and, instead, empower central banks to disregard mass unemployment and fight inflation first. Several strands of their work – the Monetarist claim that aggregate policy should be reduced to a focus on the central bank controlling the money supply to control inflation (the market would deliver the rest (high employment and economic growth, etc); the promotion of a ‘natural rate of unemployment’ such that governments who tried to reduce the unemployment rate would only accelerate inflation; and the so-called Permanent Income Hypothesis (households ignored short-term movements in income when determining consumption spending), and others – were woven together to form a anti-government phalanx. Later, absurd notions such as rational expectations and real business cycles were added to the litany of Monetarist myths, which indoctrinated graduate students (who became policy makers) even further in the cause. Over time, his damaging legacy has been eroded by researchers and empirical facts but like all tight Groupthink communities the inner sanctum remain faithful and so the research findings haven’t permeated into major shifts in the academy. It will come – but these paradigm shifts take time.Arguably, "Friedmanism" led to the Global Financial Crisis (system failure) that is still unfolding around the world, resulting in a discrediting of conventional economics, the unwinding of the post-WWII liberal order, and the inception of a new world order that is now in the making, unfortunately led by the right since the left is absorbed in navel-gazing and blaming.
The latest research effort to wipe Friedman’s theoretical legacy off the map was presented to the ASSA Annual Meetings (in Chicago, this year) at a session on January 8, 2017 by two young Harvard economists.…
Janet Yellen is really asking for research into effective demand. She sees a weakness in aggregate demand affecting aggregate supply… or potential output. That is effective demand, but she cannot even use the term effective demand because economists do not understand it.
I have been researching effective demand for 4 years. I have seen really a complete lack of understanding of what effective demand is among economists. It surprises me that Janet Yellen would be calling for research on its dynamics....Janet Yellen just might understand more about Keynes and Post Keynesianism that she wants to let on publicly. She was excoriated as a "Keynesian" by economists on the right at the time of her appointment to the Fed chair. Maybe she is nudging without rocking the boat too much.
So whilst Janet gets empirically what is wrong with modern macro research she misses the fundamental reasons this matters.

- Economics must be rebuilt around balance sheets and fundamental accounting identities
- Hence state – balance sheets- must be the basis of all models. If the model is not a state machine it cannot describe the state of anything economic.
- Hence credit and debt, and money matters
- As debt issues are fundamentally non linear and complex models which require linearisation, such as DGSE, must be discarded, they are too broken to be fixed.
Economists of all shades have generally misunderstood the theoretical structure of Keynes’s The General Theory. Quite often this is a result of misunderstanding the concept of ‘effective demand’ — one of the key theoretical innovations of The General Theory.
Jesper Jespersen untangles the concept and shows how Keynes, by taking uncertainty seriously, contributed to forming an analytical alternative to the prevailing neoclassical general equilibrium framework:Lars P. Syll’s Blog
Obviously other factors must also be at play in the ongoing producer price deflation in both countries. It may be that the features that have operated to cause price deflation in the advanced economies – inadequate effective demand because of suppression of wage incomes and continuing emphasis on fiscal consolidation, with very loose monetary policies no longer working as stimulus – are also operated to at least some degree in these economies.
Clearly, the lack of “decoupling” of these economies from the advanced economies goes beyond GDP and extends also to the behaviour of producer prices. This can only add to the concerns for policy makers in both countries, especially in India where debt default is already putting major strains on bank balance sheets.TripleCrisis
Brad DeLong wrote recently concerning the Uncertainty at the Fed…“The heart of the trouble consists in the fact that neither financial-market participants nor, it seems, the Fed itself know the true state of the economy or how best to model it – especially in the wake of the 2008 financial crisis” (link)It is a fact he says. The Fed and others do not know how best to model the state of the economy.
I stand alone with a new model for an Effective Demand limit as Keynes envisioned it
The Romers, and I suppose other neoclassical macro economists, believe that the economy tends towards full employment equilibrium and will move there on its own without need for government intervention or stimulus. They would acknowledge that following a negative shock, government stimulus spending may accelerate the recovery somewhat, as Bernstein and Romer in 2009 anticipated the Obama stimulus would speed recovery by about 6 months. They deny, however, that stimulus spending could change the permanent level of output because the economy will on its own return to full employment at a capacity output set without regard to the level of employment by factor endowments, by preferences, and by the level of exogenous technology. From this perspective, because a period of prolonged measured slow growth cannot be caused by involuntary unemployment, it must, by a priori assumption, be due to a decline in the exogenously determined growth rate in capacity. Like mosquitos on an otherwise delightful summer afternoon, slow growth is unfortunate but there is little that can safely be done about it.Gerald Friedman responds to Christina and David Romer
Or maybe we can find safe pesticides. Here I agree with John Maynard Keynes that the economy can have a low-employment equilibrium because of a lack of effective demand, and I agree with Nicholas Kaldor and Petrus Verdoorn that productivity and the growth rate of capacity can be increased by policies that push the economy to a higher level of employment. And to the contrary, periods of prolonged unemployment and underutilization of capacity can lower capacity by discouraging workers and reducing the incentive to invest, to innovate, and to raise productivity. Unfortunately, this is what has been happening in the US for the last few years; and, fortunately, there is reason to believe following Keynes/Kaldor/Verdoorn that policy can reverse this decline by pushing the economy to a higher level of output and thus a higher level of productivity….
The great tragedy of the global economic malaise is that it is caused by a shortage of something that is essentially costless to produce: money.It's beyond inane, especially post Keynes and post Lerner. Not that this was unknown or overlooked before. But Keynes and Lerner elaborated economic policy based on a theory that disproves the conventional approach.
The downscaling is said to fit with the empirical evidence, and in particular with the trends that seem to have set in since around 1980.
In other words, a sputtering economic performance over the past few decades is seen as proof that we now live in more constrained times, where limited growth puts a cap on our latitude in dealing with economic issues. People drawing this conclusion almost inevitably then jump into discussions of how this reduced latitude implies a more austere role for government, and – naturally – that everyday folks just will have to manage on less.
I have a slightly different perspective.
The onset of the downward shift coincides quite neatly with another great beginning. That of an era of economic policy focused on supply side initiatives, giveaways to the rich, and of corporate welfare. Is it simply a strange coincidence that the entire post-Reagan era is exactly that we are now describing as one of lower growth? Or is it that the right of center free market policies that have dominated policy making throughout the west since the early 1980′s, are to blame?The Radford Free Press
…Effective Demand. This is a term so rarely used in economic discourse. It is not understood. For me, effective demand sets a "definable" limit upon the utilization of labor and capital. So it follows that lower effective demand leads to lower investment, lower output, lower productivity, lower taxes and less ability to pay debts.
Effective demand is based upon labor's share of a national income.…
…sufficient Effective Demand depends upon labor receiving a larger share of national production than they currently receive. No one is going to just give it to them. Labor will have to fight for it.Effective Demand
Let Z be the aggregate supply price of the output from employing N men, the relationship between Z and N being written Z = φ(N), which can be called the Aggregate Supply Function.[5] Similarly, let D be the proceeds which entrepreneurs expect to receive from the employment of N men, the relationship between D and N being written D = f(N), which can be called theAggregate Demand Function.
Now if for a given value of N the expected proceeds are greater than the aggregate supply price, i.e. if D is greater than Z, there will be an incentive to entrepreneurs to increase employment beyond N and, if necessary, to raise costs by competing with one another for the factors of production, up to the value of N for which Z has become equal to D. Thus the volume of employment is given by the point of intersection between the aggregate demand function and the aggregate supply function; for it is at this point that the entrepreneurs’ expectation of profits will be maximised. The value of D at the point of the aggregate demand function, where it is intersected by the aggregate supply function, will be called the effective demand. Since this is the substance of the General Theory of Employment, which it will be our object to expound, the succeeding chapters will be largely occupied with examining the various factors upon which these two functions depend. — General Theory, 3, IWhat this says when worked out is that if consumption demand is insufficient to result in production at potential output using available resources, then for output at full employment to occur, the domestic private sector saving desire must either reduced, or be accommodated by an offsetting combination of the government fiscal balance (by running a deficit) and the external saving desire in the currency (increasing net exports).
