The Integral Reviews: Paper 1 – Koenig (2011)

I am always open to accept different guest blogs and I therefore very happy that “Integral” has accepted my invitation to do a number of reviews of different papers that are relevant for the discussion of monetary theory and the development of Market Monetarism.

“Integral” is a regular commentator on the Market Monetarist blogs. Integral is a pseudonym and I am familiar with his identity.

We start our series with Integral’s review of Evan Koeing’s paper “Monetary Policy, Financial Stability, and the Distribution of Risk”. I recently also wrote a short (too short) comment on the paper so I am happy to see Integral elaborating on the paper, which I believe is a very important contribution to the discussion about NGDP level targeting. Marcus Nunes has also earlier commented on the paper.

The Integral Reviews: Papers 1 – Koenig (2011)
By “Integral”

Reviewed: Evan F. Koenig, “Monetary Policy, Financial Stability, and the Distribution of Risk.” FRB Dallas Working Paper No.1111

Consider the typical debt-deflation storyline. An adverse shock pushes the price level down (relative to expected trend) and increases consumers’ real debt load. This leads to defaults, liquidation, and general disruption of credit markets. This is often-times used as justification for the central bank to target inflation or the price level, to mitigate the effect of such shocks on financial markets.

Koenig takes a twist on this view that is quite at home to Market Monetarists: he notes that since nominal debts are paid out of nominal income, any adverse shock to income will lead to financial disruption, not just shocks to the price level. One conclusion he draws out is that the central bank can target nominal income to insulate the economy against debt-deflation spirals.

He also makes a theoretical point that will resonate well with Lars’ discussion of David Eagle’s work. Recall that Eagle views NGDP targeting as the optimal way to prevent the “monetary veil” from damaging the underlying “real” economy, which he views as an Arrow-Debreu type general equilibrium economy. Koenig makes a similar observation with respect to financial risk (debt-deflation) and in particular the distribution of risk.

In a world with complete, perfect capital markets, agents will sign Arrow-Debreu state-contingent contracts to fully insure themselves against future risk (think shocks). Money is a veil in the sense that fluctuations in the price level, and monetary policy more generally, have no effect on the distribution of risk. However, the real world is much incomplete in this regard and it is difficult to imagine that one could perfectly insure against future income, price, or nominal income uncertainty. Koenig thus dispenses of complete Arrow-Debreau contracts and introduces a single debt instrument, a nominal bond. This is where the central bank comes in.

Koenig considers two policy regimes: one in which the central bank commits to a pre-announced price-level target and one in which the central bank commits to a pre-announced nominal-income target. While the price-level target neutralizes uncertainty about the future price level, it provides no insulation against fluctuations in future output. He shows that a price level target will have adverse distributional consequences: harming debtors but helping creditors. Note that this is exactly the outcome that a price-level target is supposed to avoid. By contrast a central bank policy of targeting NGDP fully insulates the economy from the combination of price and income fluctuations. It will not only have no adverse distributional consequences, it obtain a consumption pattern across debtors and creditors which is identical to that which is obtained when capital markets are complete.

At an empirical level, Koenig documents that loan delinquency is more closely related to surprise changes in NGDP than in P, providing corroborating evidence that it is nominal income, not the price level, which matters for thinking about the sustainability of the nominal debt load.

Koenig’s conclusion is succinct:

“If there are complete markets in contingent claims, so that agents can insure themselves against fluctuations in aggregate output and the price level, then “money is a veil” as far as the allocation of risk is concerned: It doesn’t matter whether the monetary authority allows random variation in the price level or nominal value of output. If such insurance is not available, monetary policy will affect the allocation of risk. When debt obligations are fixed in nominal terms, a price-level target eliminates one source of risk (price-level shocks), but shifts the other risk (real output shocks) disproportionately onto debtors. A more balanced risk allocation is achieved by allowing the price level to move opposite to real output. An example is presented in which the risk allocation achieved by a nominal-income target reproduces exactly the allocation observed with complete capital markets. Empirically, measures of financial stress are much more strongly related to nominal-GDP surprises than to inflation surprises. These theoretical and empirical results call into question the debt-deflation argument for a price-level or inflation target. More generally, they point to the danger of evaluating alternative monetary policy rules using representative-agent models that have no meaningful role for debt.”


Scott Sumner and the Case against Currency Monopoly…or how to privatize the Fed

I always enjoy reading whatever George Selgin has to say about monetary theory and monetary policy and I mostly find myself in agreement with him.

George always is very positive towards the views of Milton Friedman, which is something I true enjoy as longtime Friedmanite. I particular like George’s 2008 paper “Milton Friedman and the Case against Currency Monopoly”, in which he describes Friedman’s transformation over the years from being in favour of activist monetary policy to becoming in favour of a constant growth rule for the money supply and then finally to a basically Free Banking view.

I believe that George’s arguments make a lot of sense I and I always thought of Milton Friedman as a much more radical libertarian than it is normally the perception. In my book (it’s in Danish – who will translate it into English?) on Friedman I make the argument that Friedman is a pragmatic revolutionary.

To radical libertarians like Murray Rothbard Milton Friedman seemed like a “pinko” who was compromising with the evil state. Friedman, however, did never compromise, but rather always presented his views in pragmatic fashion, but his ideas would ultimately have an revolutionary impact.

I there are two obvious examples of this. First Friedman’s proposal for a Negative Income Tax and second his proposal school vouchers. Both ideas have been bashed by Austrian school libertarians for compromising with the enemy and for accepting government involvement in education and “social welfare”. However, there is another way to see both proposals and is as privatization strategies. The first step towards the privatization of the production of educational and welfare services.

Furthermore, Friedman’s proposals also makes people think of the advantages if the freedom of choice and once people realize that school vouchers are preferable to a centrally planned school system then they might also realize that free choice as a general principle might be preferable.

In a similar sense one could argue that Scott Sumner and other Market Monetarists are pragmatic revolutionaries when they argue in favour of nominal GDP targeting.

Why is that? Well, it is a well-known result from the Free Banking literature that a privatization of the money supply will lead to money supply becoming perfectly elastic to changes in money demand. Said, in another way any drop in velocity will be accompanied by an “automatic” increase in the money, which effectively would mean that a Free Banking system would “target” nominal NGDP. Hence, as I have often stated NGDP targeting “emulates” a Free Banking outcome. In that sense Sumner’s proposal for NGDP targeting is similar to Friedman’s proposal for school vouchers. It is a step toward more freedom of choice. Scott therefore in many ways also is a pragmatic revolutionary as Friedman was.

There is, however, one crucial difference between Friedman and Sumner is that, while Friedman was in favour of a total privatization of the school system and just saw school vouchers as a step in that direction Scott does not (necessarily) favour Free Banking. Scott argues in favour of NGDP targeting based on its own merits and not as part of a privatization strategy. This is contrary to the Austrian NGDP targeting proponents like Steve Horwitz who clearly see NGDP targeting as a step towards Free Banking. Whether Scott favours Free Banking or not does, however, not change the fact that it might very well be seen as the first step towards the total privatization of the money supply.

Sumner’s proposal the implementation of NGDP futures could in a in similar fashion be seen as a integral part of the privatization of the money supply.

Friedman famously paraphrased the French Word War I Prime Minister George Clemenceau who said that “war is much too serious matter to be entrusted to the military” to “money is much too serious a mater to be entrusted to central banker”. Scott Sumner’s proposal for NGDP targeting within a NGDP futures framework in my view is the first step to taken away central bankers’ control of the money supply…but don’t tell that to the central bankers then they might never go along with NGDP Tageting in the first place.

For Scott own view of the Free Banking story see: “An idealistic defense of pragmatism” – he of course might as well have said “A revolutionary defense of pragmatism”.


Update: I just found this fantastic quote from George Selgin (from comment section of Scott’s blog): ‘I only wish…that Scott would draw inspiration from Cato the Elder, andend each of his pleas for replacing current Fed practice with NGDP targeting with: “For the rest, I believe that the Federal Reserve System must ultimately be destroyed.”’

“Nominal Income Targeting” on Wikipedia

First Market Monetarism hit Wikipedia and now it is “Nominal Income Targeting”. It is interesting stuff. So take a look. However, the writer(s) obviously has a Market Monetarist background of some kind (and no, it is not me…). This is obviously nice, but it should be noted that Nominal Income Targeting has quite long history in the economic literature pre-dating Market Monetarism and that in my view should be reflected on the “Nominal Income Targeting”-page on Wikipedia. I also miss the link to the Free Banking literature. Furthermore, there should be cross references to other monetary policy rules such as price level targeting and inflation targeting. But the great thing about Wikipedia is that these texts over time improves…

Anyway, it is nice to see NI targeting on Wikipedia. Keep up the good work those of you who are doing the hard work on Wikipedia texts.

Krugman’s tribute to Market Monetarism

Ok, I will be completely frank here…I have always seen myself as a anti-Keynesian and I have said terrible things about Paul Krugman’s keynesianism and especially his view of the liquidity trap has made me extremely frustrated. However, there is no coming around the fact that he is a world-class economist.

Now Krugman is paying tribute to Market Monetarism. And yes, I am pretty damn proud of having coined the term Market Monetarism, but more important the Market Monetarist bloggers like Scott Sumner, David Beckworth, Bill Woolsey, Nick Rowe and Marcus Nunes are now being heard. I believe that this is of great importance if we want to see the global economy fundamentally pull out of this horrible slump.

Take a look at Krugman’s comment on Market Monetarism here.

The Hottest Idea In Monetary Policy

Its pretty simple – Scott Sumner is a revolutionary with revolutionary idea and he is breaking through big time.

He is a story from “The Hottest Idea In Monetary Policy”.

I fundamentally think that if the Federal Reserve was to start listening to Scott then a whole lot of other economic and monetary problems would be a lot easy to solve – so that’s our hope in Europe.
