In a recent lecture at the Cass Business School, Lord Adair Turner suggested that the economies of many advanced countries are in such a “mess” that policy makers should be prepared to break a taboo. They should consider carefully the pros and cons of increased fiscal deficits, explicitly and permanently financed by an increase in base money issued by central banks. In response, a lively debate on this issue has begun, which is useful for two reasons. First, it widens the scope of possible tools to manage the ongoing crisis. Second, it reminds us that there is a current crisis that needs managing.
This may seem an odd thing to say at this juncture, but many of the policies being followed currently seem directed much more to preventing the next crisis than curing the current one. Significant reductions in fiscal deficits and sharp increases in bank capital ratios are cases in point. While they clearly have desirable medium term implications, their near term effects on demand growth are unwelcome. Conversely, ultra easy monetary policy might have desirable short run effects on demand but undesirable medium term implications. In any event, it seems decidedly odd to be driving the economic car with one foot on the brake and one foot on the pedal. We need more clarity about the objectives of these diverse policies and whether they are or can be made mutually consistent.
One aspect of this broader confusion between crisis management and crisis prevention is manifest in references to the Chicago Plan to support OMF. It is true that members of the Chicago School (Milton Friedman and Henry Simons), along with Irving Fisher, suggested back in the 1930’s that government deficits should be financed directly by fiat money. Nevertheless, the motivation and recommendations in the Chicago plan were actually quite different from those currently supporting OMF. The objective of the Chicago Plan was to prevent crises not to manage them.
Dating from the time of Wicksell (and perhaps before), the insight that banks create money in the process of making loans has become more widely accepted. In effect, given a fractional reserve banking system, banks simply write up both sides of their balance sheet. This fact is what fundamentally distinguishes a monetary economy from a barter economy, and leads to the possibility (indeed, Minsky would have said, the inevitability) that excessive credit creation will lead to cycles of “boom and bust”. Both Hayek and Keynes recognized this fact.
Against this background, the Chicago plan aimed to prevent crises by taking away the capacity of private banks to create money. Narrow banking was the very core of their proposal. In contrast, OMF has to do with crisis management, with getting out of the current “mess”. Moreover, absent any suggestion of getting rid of fractional reserve banking, the increase in base money associated with OMF would have the potential to generate still more private sector debt and still more leverage. This is unfortunate since excessive debt and leverage seems to have played a big role in creating our current problems in the first place.

Another way to characterize the difference in interpretation is that Simons and Friedman were proposing a regime change, whereas those supporting OMF are proposing a policy change. Had the proposed regime change been in place, an economic downturn requiring an expanded government deficit and a rising monetary base would have been preceded by an expansionary period of declining deficits and a falling monetary base. Since this was clearly not the case in recent years, I suggest that both Simons and Friedman would have seen more risks than promise in OMF at this juncture. It is also important to note that, under the Chicago Plan, the increase in base money in bad times would have been temporary and not permanent.
In fact, if I had to emphasize just one aspect of the Chicago plan it would not be linking government finance to the provision of inside money. Rather, it would be the insight that financial structure matters for the performance of the financial system and the economy it supports. The current system we have today allows the utility functions of banks (payments, deposit taking and the provision of loans to industry) to be threatened by activities that have a real casino quality about them. Four years after the crisis, we still have banks that are too big to fail, and a shadow banking system that is so opaque there is no agreement on either how to define it or measure it. Nor is there any agreement on how these problems might be minimized
This state of affairs should change in a fundamental way. However, given the magnitude of the public sector subsidies currently given to support the current system (e.g. , lower borrowing costs for firms deemed “too big to fail”), it is not surprising that financial industry representatives are lobbying hard to keep things essentially the way they are. This can only be dealt with by polices that might have to be even more radical than the adoption of OMF
Crisis Management: What is the problem? Could OMF be part of the solution?
What is the problem we currently face? It is the need for the private sector (both borrowers and lenders) in the advanced market economies to delever after a long credit boom supported and accentuated by twenty years or more of Greenspan “puts” and other safety net measures. We are at the end of what George Soros has called the “supercycle”, characterized by rampant financial speculation, unprofitable real investments and a host of other “imbalances”. Further, the problems posed by the need for deleveraging have been accentuated by the fact that the problem does not just affect a few countries but almost every large country in the global economy. As a result, and unlike most previous debt crises, individual countries cannot count on growing out of their debt problems on the backs of the improving fortunes of their neighbors.
How did this problem become global? When the Advanced Market Economies (AME’s) repeatedly and asymmetrically relied on monetary and credit expansion to resist economic downturns, their exchange rates should have fallen. However, the Emerging market Economies (EME’s), not least China, resisted this through outright intervention in foreign exchange markets and easier monetary policies than they would otherwise have followed. In short, the problems of the AME’s were effectively imported by the EME’s, while liquidity created in the EME’s worsened the problems of the AME’s. Thus, we now have a problem of excessive leverage and dangerous “imbalances” almost everywhere. The fact that our International Monetary System (or rather, non-system) allowed this outcome, indicates that we need to go back to these “systemic” questions with great urgency.
Having identified the problem, the next question is whether still another round of stimulative macroeconomic policies might be part of the solution. This is certainly conceivable though the case is by no means watertight. There is more to an economy than just real side demand. First, demand stimulus can get in the way of deleveraging, and the McKinsey Institute reminds us that this process has hardly begun. As of 2011, only three countries (the US, South Korea and Australia) had total debt ratios (public and private) that were lower than they had been on the eve of the crisis. Second, credit related crises often result in distortions on the supply side of the economy which reduce the level of potential. This raises the risk of inflationary pressures reemerging in the wake of still more demand stimulus. The UK could well be a portent of things to come in other countries. Finally, most countries have already done a massive degree of fiscal and monetary easing, and it has not produced “strong, sustainable and balanced growth” as the G20 would like. Would “still more of the same” do any better?
A crucial, further question is whether “still more of the same” might introduce new risks that might actually be greater than the risks associated with just putting up with somewhat slower growth for a while. Or to put it another way, the economy is a highly complex system in which multiple equilibria seem possible, and whose functioning we hardly understand. In pursuit of what Hayek called “the fatal conceit”, the assumption that fallible policymakers can fix all our problems, is there not a danger that we will push the economy still further beyond what Axel Leijonhufvud calls the “corridor of stability”?
I generally agree with those who point out the downsides of monetary policy operating all on its own. First, it might not work. Keynes himself came to this conclusion as he progressed from the Treatise to the General Theory. Second, it might have “harmful adverse consequences”. I have written extensively on this, and I believe that these risks continue to be underestimated by central banks worldwide. At the moment, my greatest concern is that monetary policies are distorting enormously the functioning of financial markets. The situation today looks to me like 2007 all over again, with a sharp fall in bond and equity prices being top of my list of worries. This could have important implications for financial stability.
I also agree with the concerns raised by many about relying further on traditional, expansionary fiscal policy. If financed with more debt, as is currently the case, sovereign rates in some countries could rise in a discomforting way and perhaps even in an unsustainable way. In this regard, my principal concern is that we have no criteria to help us understand when this might happen. Two particular cases make this clear. On the one hand, I find convincing the argument of Paul De Grauwe that a number of peripheral European sovereigns have been victims of a self fulfilling market attack that could not be justified by initial (or even projected) sovereign debt levels. On the other hand, a very recent OECD study suggests that Japan, the UK and the US will face the greatest problems in stabilizing their government debt ratios. Implicitly, the policy advice is that they should address this problem urgently. Yet, these are the countries that have among the lowest sovereign borrowing costs in the OECD area. This absence of criteria is a serious impediment to giving advice to countries about the appropriateness of their fiscal stance.
Given the shortcomings of both monetary and fiscal policy on their own, is it possible that a combination of these measures, specifically OMF, might prove better able to generate “strong, balanced and sustainable growth? ”By way of analogy, it is like saying “Soup and sodium – not good. Soup and chlorine - also not good. But, soup and sodium chloride – very tasty”. Frankly, I am skeptical, although likely not as skeptical as Jens Weidman, and would like to raise a few questions just to stimulate discussion.
What precisely is the difference between OMF and what we have already done? While not presented as a coordinated package, fiscal deficits have risen sharply in a number of countries and have, to a very significant degree, been financed by expanding the balance sheet of the central bank. It is perhaps significant that the various central banks have used unconventional monetary instruments in quite different ways, indicating that there is no consensus on the best way to do it. Regardless, the bottom line is that the increased supply of base money has been matched by an increase in the demand for bank reserves and the broader monetary aggregates have responded little, if at all. How might a more coordinated fiscal-monetary package have led (or lead) to a different outcome?
Those supporting OMF suggest that the essential difference between what has been done, and what they suggest, is that the infusion of base money will be described as “permanent”. What is not clear is how this “permanence” might alter the transmission mechanism, not least by overcoming the increased demand for cash reserves in any reasonable time period. One possibility is that, absent an increase in debt, there will be less of a tendency for sovereign rates to rise due to fears about sustainability. Conversely, is there not also the possibility that increased deficits, financed by monetary expansion, might lead to higher inflationary expectations and higher sovereign bond yields? I think this is possible and return to it below.
A final point concerning permanence is whether the monetary authority can credibly commit to such “permanence”. Central banks have repeatedly changed both their objectives and their preferred analytical models over the last 30 years. Moreover, they are in the process of doing so again. Astonishingly, they seem increasingly to be targeting real variables, as in the 1960’s and prior to the insights of Friedman and Phelps. Who then would believe them when they said “Trust me, it’s permanent”?
Another area where I am unclear has to do with the role of inflation and changes in inflationary expectations. For example, in his Cass Lecture, Lord Turner presents a traditional model in which inflation is driven essentially by the output “gap” and “independent” expectations. In the present juncture, this would likely imply that inflation was not likely to get out of hand any time soon. Yet, a large and permanent addition to the stock of base money would seem to have clear inflationary implications over the longer term. Indeed, a number of people (Abenomics?) would actually seem to welcome such an outcome since, assuming nominal interest rates can be held down, it would serve to reduce the real burden of sovereign debt. Evidently, the threat of an inflationary outcome would be increased by worries about fiscal dominance, which would likely be exacerbated by plans of OMF. Were there to be a related shift downward in the demand for base money, and a shift downward in the demand for broader monetary aggregates, this inflationary process could proceed very rapidly. Indeed, we have seen it happen many times over the course of the years, not least in Latin America.
Which brings me to a last puzzle. If it is at least possible that inflation could become a problem, does this not imply that the “apparently permanent” increase in base money might have to be reduced or offset by the use of macroprudential or other non traditional instruments? The first alternative raises the possibility that the original monetary infusion was both permanent and temporary. Like Schrodinger’s cat, it is both alive and dead which is not easy to understand. As for macroprudential measures, our knowledge of how well they work is in its infancy. It would be a big gamble to put too much faith in them to offset a monetary induced wave of inflation, to say nothing of all the other imbalances that might naturally arise in such circumstances.
My comments thus far might seem to indicate I am rather pessimistic about getting out of this “mess”. That is not quite right. I am just concerned about an over reliance on macroeconomic stimulus to do so, fearing that it might do more harm than good. Rather, I would use a blend of policies, chosen to reflect the special difficulties posed in trying to exit from a credit driven recession. They would have both demand and supply side elements, to respect the spirit of both Keynes and Hayek. I am, however, under no illusions when it comes to the political acceptability of some (all?) of these suggestions.
First, we need much more international cooperation on macro stimulus. Those countries in the best position to stimulate demand , should do so. Countries with large current account surpluses have more room for maneuver than others. Nominal exchange rate changes, where possible, must be accepted as part of the process of adjustment.
Second, we need more public and private investment. For the former, markets must be convinced that any increase in government liabilities comes with an associated increase in a productive asset. For the latter, we must try to create a more business friendly environment, not least with some of the uncertainties removed about the incidence of future tax burdens.
Third, we need explicit debt reduction on the part of ultimate borrowers, probably recapitalization (or closure) of the banks that lent to them, and in some cases international support for sovereigns who have themselves become over extended. Where sovereigns do have some room to increase debt, the case for using this room to stabilize the banking system (rather than direct spending or tax cuts) should be strongly considered (as suggested by my previous colleague, Claudio Borio, in BIS Working Paper 395).
Fourth, we need structural reforms to raise the potential for growth and to reduce the burden of debt service. As chairman of the EDRC at the OECD, I suggest that there are many “low hanging fruit” just waiting to be picked.
Crisis Prevention: The need for a new mindset
When the next credit cycle begins to emerge, we need to use policy instruments to “lean against the wind”. Even if all excesses cannot be avoided, by using tighter policies to constrain the amplitude of the boom we will also constrain the amplitude of the bust. Further, there will be more room to ease policies if they have been previously tightened. While there is a lively debate on how this “leaning” might be done, I would suggest the joint use of monetary and macroprudential instruments. Each has advantages and shortcomings, likely with a different balance in different countries, which makes the use of some combination of instruments seem more plausible. As I said above, we are in unchartered territory here.
As for the Simons/Friedman proposals, they come down to a rule for the rate of growth of the money stock with the objective of “ensuring” price stability. The problem with this assertion is that it depends on the assumption of a stable demand function for money (the “V” in MV=PT), which experience shows is far from being the case. As Gerry Bouey, my old boss at the Bank of Canada put it, after we gave up our monetarist experiment of the late 1970’s, “We didn’t abandon the monetary aggregates, they abandoned us”. Moreover with the spectacular increase in the size of the shadow banking system, I suspect the problem of monetary instability has become even worse in recent decades.
I would finally make a broader point. During the whole post War period, we have tended to follow highly activist macroeconomic policies (first fiscal and then monetary) with that activism much more apparent in resisting downturns than upturns. In short, we have followed a highly asymmetric set of macroeconomic policies which have both encouraged and rewarded imprudent behavior. Moreover, the upshot of this asymmetry has been a gradual ratcheting down of policy rates to essentially zero, and a gradual ratcheting up of government debt to levels that look increasingly unsustainable. In effect, these policies not only helped create the current crisis, but removed our capacity to deal with it using macroeconomic instruments. We have shot ourselves in the foot.
To avoid big crises in the future, we must become more willing to accept minor downturns, mini crises, and the occasional failure of financial institutions. No financial institution should be too big to fail. Again, I am under no illusions as to how politically acceptable this might be in a world dominated by “short term“ objectives, the popular belief that “something must be done”, and ample funding from lobbyists to fight meaningful reforms. Nevertheless, I continue to believe that this approach provides the surest means of fighting the accumulation of moral hazard and bad behavior that has led us to our current and still precarious situation.

In short, we have followed a highly asymmetric set of macroeconomic policies which have both encouraged and rewarded imprudent behavior. Moreover, the upshot of this asymmetry has been a gradual ratcheting down of policy rates to essentially zero, and a gradual ratcheting up of government debt to levels that look increasingly unsustainable. In effect, these policies not only helped create the current crisis, but removed our capacity to deal with it using macroeconomic instruments. We have shot ourselves in the foot.
To avoid big crises in the future, we must become more willing to accept minor downturns, mini crises, and the occasional failure of financial institutions. No financial institution should be too big to fail. Again, I am under no illusions as to how politically acceptable this might be in a world dominated by “short term“ objectives, the popular belief that “something must be done”, and ample funding from lobbyists to fight meaningful reforms. Nevertheless, I continue to believe that this approach provides the surest means of fighting the accumulation of moral hazard and bad behavior that has led us to our current and still precarious situation.
