Remembering the “Market” in Market Monetarism

A couple of days ago the young and talented George Mason University economist Alex Salter wrote the following statement on his Facebook account:

I wish market monetarists would put relatively more emphasis on the “market” bit.

I agree with Alex as I believe that one of the main points of Market Monetarism is that not only do money matters, but it equally important that markets matter. Hence, it is no coincidence that the slogan of my blog ismarkets matter, money matters” and it was after all me who coined the phrase Market Monetarism.

Paul Krugman used to call Scott Sumner a quasi-monetarist, but I always thought that that missed an important point about Scott’s views (and my own views) and that of course is the “market” bit. In fact Alex’s statement reminded me of a blog post that I wrote back in January 2012 on exactly this topic.

This is from my post “Don’t forget the “Market” in Market Monetarism”:

As traditional monetarists Market Monetarists see money as being at the centre of macroeconomic discussion. To us both inflation and recessions are monetary phenomena. If central banks print too much money we get inflation and if they print to little money we get recession or even depression.

This is often at the centre of the arguments made by Market Monetarists. However, we are exactly Market Monetarists because we have a broader view of monetary policy than traditional monetarists. We deeply believe in markets as the best “information system” – also about the stance of monetary policy. Even though we certainly do not disregard the value of studying monetary supply numbers we believe that the best indicator(s) of monetary policy stance is market pricing in currency markets, commodity markets, fixed income markets and equity markets. Hence, we believe in a Market Approach to monetary policy in the tradition of for example of “Manley” Johnson and Robert Keheler.

Interestingly enough Alex himself has just recently put out a new working paper – “There a Self-Enforcing Monetary Constitution?” –
that makes the exact same point. This is the abstract from Alex’s paper:

This paper uses insights from monetary theory and constitutional political economy to discover what a self-enforcing monetary constitution — one whose rules did not require external enforcement — would look like. I argue that a desirable monetary constitution (a) institutionalizes an environment conducive to economic calculation via an unhampered price mechanism and (b) enables agents acting within the system to uphold the rule even in the presence of deviations from ideal knowledge and incentive assumptions. I show two radical alternatives to current monetary institutions — a version of NGDP targeting that relies on market implementation of monetary policy and free banking — meet these requirements, and thus represent self-enforcing monetary constitutions. I ultimately conclude that the maintenance of a stable monetary framework necessitates branching out from monetary theory narrowly conceived and considering insights from political economy, and constitutional political economy in particular.

I very much like Alex’s constitutional spin on the monetary policy issue. I strongly agree that the biggest problem in the conduct of monetary policy – basically everywhere in the world – is the lack of a clear rule based framework for the monetary system and equally agree that NGDP targeting with “market implication” and Free Banking fulfill the requirement for a monetary constitution. Or as I put it in my 2012 post:

In fact we want to take out both the “central” and “banking” out of central banking and ideally replace monetary policy makers with the power of the market. Scott Sumner has suggested that the central banks should use NGDP futures in the conduct of monetary policy. In Scott’s set-up monetary policy ideally becomes “endogenous”. I on my part have suggested the use of prediction markets in the conduct of monetary policy.

…Even though Market Monetarists do not necessarily advocate Free Banking there is no doubt that Market Monetarist theory is closely related to the thinking of Free Banking theorist such as George Selgin and I have early argued that NGDP level targeting could be see as an “privatisation strategy”. A less ambitious interpretation of Market Monetarism is certainly also possible, but no matter what Market Monetarists stress the importance of markets – both in analysing monetary policy and in the conduct monetary policy.

Hence, Alex and I are in fundamental agreement, but I also want to acknowledge that we – the Market Monetarists – from time to time are more (too?) focused on the need to ease monetary policy – in the present situation in the US or the euro zone – than to talk about “market implementation” of monetary policy.

There are numerous reasons for this, but the key reason is probably one of political realism, but there is also a serious risk in letting “political realism” dictate the agenda. Therefore, I think we should listen to Alex’s advice and try to stress the “market” bit in Market Monetarism a bit more. Afterall, we have made serious inroads in the global monetary policy debate in regard to NGDP level targeting – why should we not be able to make the same kind of progress when it comes to “market implementation” of monetary policy?

Markets are telling us where NGDP growth is heading

I am still in Provo Utah and even though I have had a busy time I have watch a bit of Bloomberg TV and CNBC over the last couple of days (to fight my jet lag). I have noticed some very puzzling comments from commentators. There have been one special theme and that has come up again and again over the last couple of days among the commentators on US financial TV and that is that “yeah, monetary easing might be positive for the markets, but it is not have any impact on the real economy”. This is a story about disconnect between the economy and the markets.

I find that perception very odd, but it seems like a lot of commentators simply are not mentally able to accept that monetary policy is highly effective. The story goes that when the Federal Reserve and the ECB moves towards monetary easing then it might do the markets good, but “real people” will not be helped. I find it unbelievable that well-educated economists would make such claims.

Markets are forward-looking and market pricing is the best tool we have for forecasting the future. When stock prices are rising, bond yields are rising, the dollar is weakening and commodity prices are going up then it is a very good indication that monetary conditions are getting easier and easier monetary conditions mean higher nominal GDP growth (remember MV=NGP!) and with sticky prices and excess capacity that most likely also mean higher real GDP growth. That has always been that case and that is also the case now. There is no disconnect between the markets and the economy, but there is a disconnect between what many commentators would like to see (that monetary policy is not working) and the reality.

To try to illustrate the connection between the markets and NGDP I have constructed a very simple index to track market expectations of future NGDP. I have only used two market indicators – a dollar index and the S&P500. I am constructed an index based on these two indicators – I have looked year-year percentage changes in both indices. I have standardized the indices and deducted them from each other – remember higher S&P500 means higher NGDP, but a stronger dollar (a higher USD index) means lower NGDP. I call this index the NGDP Market Indicator. The indicator has been standardized so it has the same average and standard deviation as NGDP growth since 1990.

As the graph below shows this simple indicator for future NGDP growth has done a fairly good job in forecasting NGDP since 1990. (You can see the background data for the indicator here).

During the 1990s the indicator indicates a fairly stable growth rate of NGDP and that is in fact what we had. In 1999 the indicator started to send a pretty clear signal that NGDP growth was going to slow – and that is exactly what we got. The indicator also clearly captures the shock in 2008 and the recovery in 2009-10.

It is obvious that this indicator is not perfect, but the indicator nonetheless clearly illustrates that there in general is no disconnect between the markets and the economy – when stock prices are rising and the dollar is weakening at the same time then it would normally be indicating that NGDP growth will be accelerating in the coming quarters. Having that in mind it is of course worrying that the indicator in the last couple of months has been indicating a relative sharp slowdown in NGDP growth, which of course provides some justification for the Fed’s recent action.

I must stress that I have constructed the NGDP market indicator for illustrative purposes, but I am also convinced that if commodity prices and bond yields and maybe market inflation expectations were included in the indicator and the weighing of the different sub-indicators was based on proper econometric methods (rather than a simple unweighted index) then it would be possible to construct an indicator that would be able to forecast NGDP growth 1-4 quarters ahead very well.

So again – there is no disconnect between the markets and the economy. Rather market prices are very good indicators of monetary policy “easiness” and therefore of future NGDP. In fact there is probably no better indicator for the monetary policy stance than market prices and the Federal Reserve and other central banks should utilize market prices much more in assessing the impact of monetary policy on the economy than it presently the case. An obvious possibility is also to use a future NGDP to guide monetary policy as suggested by Scott Sumner.

David Laidler: “Two Crises, Two Ideas and One Question”

The main founding fathers of monetarism to me always was Milton Friedman, Anna Schwartz, Karl Brunner, Allan Meltzer and David Laidler. The three first have all now passed away and Allan Meltzer to some extent seems to have abandoned monetarism. However, David Laidler is still going strong and maintains his monetarist views. David has just published a new and very interesting paper – “Two Crises, Two Ideas and One Question” – in which he compares the Great Depression and the Great Recession through the lens of history of economic thought.

David’s paper is interesting in a number of respects and any student of economic history and history of economic thought will find it useful to read the paper. I particularly find David’s discussion of the views of Allan Meltzer and other (former!?) monetarists interesting. David makes it clear that he think that they have given up on monetarism or as he express it in footnote 18:

“In this group, with which I would usually expect to find myself in agreement (about the Great Recession), I include, among others, Thomas Humphrey, Allan Meltzer, the late Anna Schwartz, and John Taylor, though the latter does not have quite the same track record as a monetarist as do the others.”

Said in another way David basically thinks that these economists have given up on monetarism. However, according to David monetarism is not dead as another other group of economists today continues to carry the monetarist torch – footnote 18 continues:

“Note that I self-consciously exclude such commentators as Timothy Congdon (2011), Robert Hetzel (2012) and that group of bloggers known as the “market monetarists”, which includes Lars Christensen, Scott Sumner, Nicholas Rowe …. – See Christensen (2011) for a survey of their work – from this list. These have all consistently advocated measures designed to increase money growth in recent years, and have sounded many themes similar to those explored here in theory work.”

I personally think it is a tremendous boost to the intellectual standing of Market Monetarism that no other than David Laidler in this way recognize the work of the Market Monetarists. Furthermore and again from a personal perspective when David recognizes Market Monetarist thinking in this way and further goes on to advocate monetary easing as a respond to the present crisis I must say that it confirms that we (the Market Monetarists) are right in our analysis of the crisis and helps my convince myself that I have not gone completely crazy. But read David’s paper – there is much more to it than praise of Market Monetarism.

PS This year it is exactly 30 years ago David’s book “Monetarist Perspectives” was published. I still would recommend the book to anybody interested in monetary theory. It had a profound impact on me when I first read it in the early 1990s, but I must say that when I reread it a couple of months ago I found myself in even more agreement with it than was the case 20 years ago.

Update: David Glasner also comments on Laidler’s paper.

NGDP level targeting – the true Free Market alternative (we try again)

Most of the blogging Market Monetarists have their roots in a strong free market tradition and nearly all of us would probably describe ourselves as libertarians or classical liberal economists who believe that economic allocation is best left to market forces. Therefore most of us would also tend to agree with general free market positions regarding for example trade restrictions or minimum wages and generally consider government intervention in the economy as harmful.

I think that NGDP targeting is totally consistent with these general free market positions – in fact I believe that NGDP targeting is the monetary policy regime which best ensures well-functioning and undistorted free markets. I am here leaving aside the other obvious alternative, which is free banking, which my readers would know that I have considerable sympathy for.

However, while NGDP targeting to me is the true free market alternative this is certainly not the common view among free market oriented economists. In fact I find that most of the economists who I would normally agree with on other issues such as labour market policies or trade policy tend to oppose NGDP targeting. In fact most libertarian and conservative economists seem to think of NGDP targeting as some kind of quasi-keynesian position. Below I will argue why this perception of NGDP targeting is wrong and why libertarians and conservatives should embrace NGDP targeting as the true free market alternative.

Why is NGDP targeting the true free market alternative?

I see six key reasons why NGDP level targeting is the true free market alternative:

1) NGDP targeting is ”neutral” – hence unlike under for example inflation targeting NGDPLT do not distort relative prices – monetary policy “ignores” supply shocks.
2) NGDP targeting will not distort the saving-investment decision – both George Selgin and David Eagle argue this very forcefully.
3) NGDP targeting ”emulates” the Free Banking allocative outcome.
4) Level targeting minimizes the amount of discretion and maximises the amount of accountability in the conduct of monetary policy. Central banks cannot get away with “forgetting” about past mistakes. Under NGDP level targeting there is no letting bygones-be-bygones.
5) A futures based NGDP targeting regime will effective remove all discretion in monetary policy.
6) NGDP targeting is likely to make the central bank “smaller” than under the present regime(s). As NGDP targeting is likely to mean that the markets will do a lot of the lifting in terms of implementing monetary policy the money base would likely need to be expanded much less in the event of a negative shock to money velocity than is the case under the present regimes in for example the US or the euro zone. Under NGDP targeting nobody would be calling for QE3 in the US at the moment – because it would not be necessary as the markets would have fixed the problem.

So why are so many libertarians and conservatives sceptical about NGDP targeting?

Common misunderstandings:

1) NGDP targeting is a form of “countercyclical Keynesian policy”. However, Market Monetarists generally see recessions as a monetary phenomenon, hence monetary policy is not supposed to be countercyclical – it is supposed to be “neutral” and avoid “generating” recessions. NGDP level targeting ensures that.
2) Often the GDP in NGDP is perceived to be real GDP. However, NGDP targeting does not target RGDP. NGDP targeting is likely to stabilise RGDP as monetary shocks are minimized, but unlike for example inflation targeting the central bank will NOT react to supply shocks and as such NGDP targeting means significantly less “interference” with the natural order of things than inflation targeting.
3) NGDP targeting is discretionary. On the contrary NGDP targeting is extremely ruled based, however, this perception is probably a result of market monetarists call for easier monetary policy in the present situation in the US and the euro zone.
4) Inflation will be higher under NGDP targeting. This is obviously wrong. Over the long-run the central bank can choose whatever inflation rate it wants. If the central bank wants 2% inflation as long-term target then it will choose an NGDP growth path, which is compatible which this. If the long-term growth rate of real GDP is 2% then the central bank should target 4% NGDP growth path. This will ensure 2% inflation in the long run.

Another issue that might be distorting the discussion of NGDP targeting is the perception of the reasons for the Great Recession. Even many libertarian and conservative economists think that the present crisis is a result of some kind of “market disorder” – either due to the “natural instability” of markets (“animal spirits”) or due to excessively easy monetary policy in the years prior to the crisis. The proponents of these positions tend to think that NGDP targeting (which would mean monetary easing in the present situation) is some kind of a “bail out” of investors who have taken excessive risks.

Obviously this is not the case. In fact NGDP targeting would mean that central bank would get out of the business of messing around with credit allocation and NGDP targeting would lead to a strict separation of money and banking. Under NGDP targeting the central bank would only provide liquidity to “the market” against proper collateral and the central bank would not be in the business of saving banks (or governments). There is a strict no-bail out clause in NGDP targeting. However, NGDP targeting would significantly increase macroeconomic stability and as such sharply reduce the risk of banking crisis and sovereign debt crisis. As a result the political pressure for “bail outs” would be equally reduced. Similarly the increased macroeconomic stability will also reduce the perceived “need” for other interventionist measures such as tariffs and capital control. This of course follows the same logic as Milton Friedman’s argument against fixed exchange rates.

NGDP level targeting as a privatization strategy

As I argue above there are clear similarities between the allocative outcome under Free Banking – hence a fully privatized money supply – and NGDP targeting. In fact I believe that NGDP level targeting might very well be seen as part of a privatization strategy. (I have argued that before – see here)

Hence, a futures based NGDP targeting regime would basically replace the central bank with a computer in the sense that there would be no discretionary decisions at all in the conduct of monetary policy. In that sense the futures based NGDP targeting regime would be similar to a currency board, but instead of “pegging” monetary policy to a foreign currency monetary policy would be “pegged” to the market expectation of future nominal GDP. This would seriously limit the discretionary powers of central banks and a truly futures based NGDP targeting regime in my view would only be one small step away from Free Banking. This is also why I do not see any conflict between advocating NGDP level targeting and Free Banking. This of course is something, which is fully recognised by Free Banking proponents such as George Selgin, Larry White and Steve Horwitz.

PS this is no the first time I try to convince libertarians and conservatives that NGDP level targeting is the true free market alternative. See my first attempt here.

Selgin’s challenge to the Market Monetarists

Anybody who have been following my blog knows how much admiration I have for George Selgin so when George speaks I listen and if he says I am wrong I would not easily dismiss it without very careful consideration.

Now George has written a challenge on Freebanking.org for us Market Monetarists. In his post “A Question for the Market Monetarists” George raises a number of issues that deserves answers. Here is my attempt to answer George’s question(s). But before you start reading I will warn you – as it is normally the case I think George is right at least to some extent.

Here is George:

“Although my work on the “Productivity Norm” has led to my being occasionally referred to as an early proponent of Market Monetarism, mine has not been among the voices calling out for more aggressive monetary expansion on the part of the Fed or ECB as a means for boosting employment.”

While it is correct that Market Monetarists – and I am one of them – have been calling for monetary easing both in the US and the euro zone this to me is not because I want to “boost employment”. I know that other Market Monetarists – particularly Scott Sumner – is more outspoken on the need for the Federal Reserve to fulfill it’s “dual mandate” and thereby boost employment (Udpate: Evan Soltas has a similar view – see comment section). I on my part have always said that I find the Fed’s dual mandate completely misguided. Employment is not a nominal variable so it makes no sense for a central bank to target employment or any other real variable. I am in favour of monetary easing in the euro zone and the US because I want the Fed and the ECB to undo the mistakes made in the past. I am not in favour of monetary policy letting bygones-be-bygones. I do, however, realise that the kind of monetary easing I am advocating likely would reduce unemployment significantly in both the euro zone and the US. That would certainly be positive, but it is not my motive for favouring monetary easing in the present situation. See here for a discussion of Fed’s mandate and NGDP targeting.

Said in another way what I want the is that the Fed and the ECB should to live up to what I have called Selgin’s monetary credo:

“The goal of monetary policy ought to be that of avoiding unnatural fluctuations in output…while refraining from interfering with fluctuations that are “natural.” That means having a single mandate only, where that mandate calls for the central bank to keep spending stable, and then tolerate as optimal, if it does not actually welcome, those changes in P and y that occur despite that stability“

Back to George:

“There are several reasons for my reticence. The first, more philosophical reason is that I think the Fed is quite large enough–too large, in fact, by about $2.8 trillion, about half of which has been added to its balance sheet since the 2008 crisis. The bigger the Fed gets, the dimmer the prospects for either getting rid of it or limiting its potential for doing mischief. A keel makes a lousy rudder.”

This is the Free Banking advocate George Selgin speaking. The Free Banking advocate Lars Christensen does not disagree with George’s fundamental free banking position. However, George also knows that in the event of a sharp rise in money demand in a free banking regime the money supply will expanded automatically to meet that increase in money demand (I learned that from George). In 2007-9 we saw a sharp rise in dollar demand and the problem was not that the Fed did too much to meet that demand, but rather that it failed to meet the increase in money demand. Something George so well has described in for example his recent paper on the failed US primary dealer system. See here.

However, I certainly agree with George’s position that had monetary policy been conducted in another more rational way – for example within a well-defined NGDP targeting regime and a proper lender-of-last-resort regime – then the Fed would likely have had to expand it’s money base much less than has been the case. Here I think that we Market Monetarists should listen to George’s concerns. Sometimes some of us are to eager to call for what could sound like a discretionary expansion of the money base. This is not really the Market Monetarist position. The Market Monetarist position – at least as I think of it – is that the Fed and the ECB should “emulate” a free banking outcome and ensure that any increase in money demand is met by an increase in the money base. This should obviously be based on a rule based set-up rather than on discretionary monetary policy changes. Both the Fed and the ECB have been insanely discretionary in the past four years.

Back to George:

“The second reason is that I worry about policy analyses (such as this recent one) that treat the “gap” between the present NGDP growth path and the pre-crisis one as evidence of inadequate NGDP growth. I am, after all, enough of a Hayekian to think that the crisis of 2008 was itself at least partly due to excessively rapid NGDP growth between 2001 and then, which resulted from the Fed’s decision to hold the federal funds rate below what appears (in retrospect at least) to have been it’s “natural” level.” 

This is a tricky point on which the main Market Monetarist bloggers do not necessarily agree. Scott Sumner and Marcus Nunes have both strongly argued against the “Hayekian position” and claim that US monetary policy was not too easy prior to 2008. David Beckworth prior to the crisis clearly was arguing that US monetary policy was too easy. My own position is somewhere in between. I certainly think that monetary policy was too easy in certain countries prior to the crisis. I for example have argued that continuously in my day-job back in 2006-7 where I warned that monetary conditions in for example Iceland, the Baltic States and in South Eastern European were overly loose. I am, however, less convinced that US monetary policy was too easy – for the US economy, but maybe for other economies in the world (this is basically what Beckworth is talking about when he prior to crisis introduced the concept the Fed as a “monetary superpower”).

However, it would be completely wrong to argue that the entire drop in NGDP in the US and the euro zone is a result of a bubble bursting. In fact if there was any “overshot” on pre-crisis NGDP or any “bubbles” (whatever that is) then they certainly long ago have been deflated. I am certain that George agrees on that. Therefore the possibility that there might or might have been a “bubble” is no argument for maintain the present tight monetary conditions in the euro zone and the US.

That said, as time goes by it makes less and less sense to talk about returning to a pre-crisis trend level for NGDP both in the US and the euro zone. But let’s address the issue in slightly different fashion. Let’s say we are where presented with two different scenarios. In scenario 1 the Fed and the ECB would bring back NGDP to the pre-crisis trend level, but then thereafter forget about NGDP level targeting and just continue their present misguided policies. In scenario 2 both the Fed and the ECB announce that they in the future will implement NGDP level targeting with the use of NGDP futures (as suggested by Scott), but would initiate the new policy from the present NGDP level. I would have no doubt that I would prefer the second scenario. I can of course not speak from my Market Monetarist co-conspiritors, but to me the it is extremely important that we return to a rule based monetary policy. The actual level of NGDP in regard is less important.

And then finally George’s question:

“And so, my question to the MM theorists: If a substantial share of today’s high unemployment really is due to a lack of spending, what sort of wage-expectations pattern is informing this outcome?”

This is an empirical question and I am not in a position to give an concrete answer to that. However, would argue that most of the increase in unemployment and the lack of a recovery in the labour market both in the US and the euro zone certainly is due to a lack of spending and therefore monetary easing would likely significantly reduce unemployment in both the US and the euro zone.

Finally I don’t really think that George challenge to the Market Monetarists is question about wage-expectations. Rather I think George wants us to succeed in our endeavor to get the ECB and the Fed to target NGDP. While George does not spell it out directly I think he share the concern that I from time to time has voiced that we should be careful that we do not sound like vulgar Keynesians screaming for “monetary stimulus”. To many the call for QE3 from the sounds exactly like that and for exact that reason I have cautious in calling for another badly executed QE from the Fed. Yes, we certainly need to call for monetary easing, but no one should be in doubt that we want it within a proper ruled based regime.

I have in a number of posts since I started blogging in October last year warned that we should put more emphasis on our arguments for a rule based regime than on monetary expansion as our call for monetary easing creates confusion about what we really think. Or has I stated it back in November last year my my post NGDP targeting is not a Keynesian business cycle policy“:

“I believe that much of the confusing about our position on monetary policy has to do with the kind of policy advise that Market Monetarist are giving in the present situation in both the US and the euro zone.

Both the euro zone and the US economy is at the presently in a deep recession with both RGDP and NGDP well below the pre-crisis trend levels. Market Monetarists have argued – in my view forcefully – that the reason for the Great Recession is that monetary authorities both in the US and the euro zone have allowed a passive tightening of monetary policy (See Scott Sumner’s excellent paper on the causes of the Great Recession here) – said in another way money demand growth has been allowed to strongly outpaced money supply growth. We are in a monetary disequilibrium. This is a direct result of a monetary policy mistakes and what we argue is that the monetary authorities should undo these mistakes. Nothing more, nothing less. To undo these mistakes the money supply and/or velocity need to be increased. We argue that that would happen more or less “automatically”…if the central bank would implement a strict NGDP level target.

So when Market Monetarists (have)… called for “monetary stimulus” it NOT does mean that (we) want to use some artificial measures to permanently increase RGDP. Market Monetarists do not think that that is possible, but we do think that the monetary authorities can avoid creating a monetary disequilibrium through a NGDP level target where swings in velocity is counteracted by changes in the money supply…

Therefore, we are in some sense to blame for the confusion. We should really stop calling for “monetary stimulus” and rather say “stop messing with Say’s Law, stop creating a monetary disequilibrium”. Unfortunately monetary policy discourse today is not used to this kind of terms and many Market Monetarists therefore for “convenience” use fundamentally Keynesian lingo.” 

I hope that that is an answer to George’s more fundamental challenge to us Market Monetarists. We are not keynesians and we are strongly against discretionary monetary policy and I want to thank George for telling us to be more clear about that.

Finally I should stress that I do not speak on behalf of Scott, Marcus, Nick, 2 times David, Josh and Bill (and all the other Market Monetarists out there) and I am pretty sure that the rest of the gang will join in with answers to George. After all most of us are Selginians.

Update: George now has an update where is answers his own question. I think it is a good answer. Here is George:

“My further reflections make me more inclined to see merit in Market Monetarists’ arguments for more accommodative monetary policy.”

Update 2: Scott also has a comment on George’s posts. I think this is highly productive. We are moving forward in our understanding of not only the theoretical foundation for Market Monetarism, but also in the understanding of the economic situation.

Project African Monetary Reform (PAMR)

Project African Monetary Reform (PAMR) – post 1

The blogoshere is full of debates about US monetary policy and the mistakes of the ECB are also hotly debated. However, other than that there is really not much debate in the blogoshere about monetary policy issues in other countries. I have from I started blogging said that I wanted to broaden the monetary debate and make it less US-centric. Unfortunately I must say I also tend to write a lot about US monetary policy and there is no doubt that most of my readers are primarily interested in US monetary affairs. However, I still want to have a broader perspective on monetary theory, policy and history. Therefore as of today I am launching Project African Monetary Reform (PAMR).

I have no clue where PAMR will lead me other than I have a large interest in the African continent and it’s economies so why not combine it with my interest in monetary policy? My regular readers will know that I already have produced a number of posts related to African monetary issues. PAMR as such will not be a major change and I will not promise any regularity in my posts in the PAMR “series”, but I hope PAMR can be a framework within which I can write a bit more on African monetary matters. I will not get into the business of forecasting central bank behavior and market movements (I spend time on that kind of thing in my day-job), but I will hope to contribute to the discussion about monetary reform in Africa. Something still badly needed in many African countries.

In the process of studying monetary reform issues in Africa – we might even learn some good lessons for more “developed” economies like the US and the euro zone. So even if you are not interested in what is going on in Africa you might learn from tracking PAMR.

I therefore also would like to invite other economists, academics and policy makers with interest in African monetary reform to get in contact with me so we might be able to build a network of people with such interests. Furthermore, I would as always welcome guest posts concerning African monetary issues from other economists with special knowledge or interest in African monetary reform. I can be contacted at lacsen@gmail.com

Furthermore, I will invite you my dear readers to give me suggestions for the next post in the PAMR series. I want to take a look at the monetary policy set-up in a “random” African country. You my dear readers will make the choice on what country I should start with. But I rule out writing something on the three large ones: South Africa, Nigeria and Egypt. You can write the suggestion here or drop me a mail. I am all hears.

By chance I today found an ECB working paper from 2004 – “The Great Depression and the Friedman-Schwartz hypothesis” by Christiano, Motto and Rostagno.

Here is the abstract:

“We evaluate the Friedman-Schwartz hypothesis that a more accommodative monetary policy could have greatly reduced the severity of the Great Depression. To do this, we first estimate a dynamic, general equilibrium model using data from the 1920s and 1930s. Although the model includes eight shocks, the story it tells about the Great Depression turns out to be a simple and familiar one. The contraction phase was primarily a consequence of a shock that induced a shift away from privately intermediated liabilities, such as demand deposits and liabilities that resemble equity, and towards currency. The slowness of the recovery from the Depression was due to a shock that increased the market power of workers. We identify a monetary base rule which responds only to the money demand shocks in the model. We solve the model with this counterfactual monetary policy rule. We then simulate the dynamic response of this model to all the estimated shocks. Based on the model analysis, we conclude that if the counterfactual policy rule had been in place in the 1930s, the Great Depression would have been relatively mild.”

It is interesting stuff and you would imagine that the model developed in the paper could also shed light on the causes and possible cures for the Great Recession as well.

Is it only me who is reminded about 2008-9 when you read this:

“The empirical exercise conducted on the basis of the model ascribes the sharp contraction of 1929-1933 mainly to a sudden shift in investors’ portfolio preferences from risky instruments used to finance business activity to currency (a flight-to-safety explanation). One interpretation of this finding could be that households . in strict analogy with commercial banks holding larger cash reserves against their less liquid assets . might add to their cash holdings when they feel to be overexposed to risk. This explanation seems plausible in the wake of the rush to stocks that occurred in the second half of the 1920.s. The paper also documents how the failure of the Fed in 1929-1933 to provide highpowered money needed to meet the increased demand for a safe asset led to a credit crunch which in turn produced deflation and economic contraction.”

The authors also answer the question about the appropriate policy response.

“We finally conduct a counterfactual policy experiment designed to answer the following questions: could a different monetary policy have avoided the economic collapse of the 1930s? More generally: To what extent does the impossibility for central banks to cut the nominal interest rate to levels below zero stand in the way of a potent counter-deflationary monetary policy? Our answers are that indeed a different monetary policy could have turned the economic collapse of the 1930s into a far more moderate recession and that the central bank can resort to an appropriate management of expectations to circumvent – or at least loosen – the lower bound constraint.

The counterfactual monetary policy that we study temporarily expands the growth rate in the monetary base in the wake of the money demand shocks that we identify. To ensure that this policy does not violate the zero lower-bound constraint on the interest rate, we consider quantitative policies which expand the monetary base in the periods a shock. By injecting an anticipated inflation effect into the interest rate, this delayed-response feature of our policy prevents the zero bound constraint from binding along the equilibrium paths that we consider. At the same time, by activating this channel, the central bank can secure control of the short-term real interest rate and, hence, aggregate spending.

The conclusion that an appropriately designed quantitative policy could have largely insulated the economy from the effects of the major money demand shocks that had manifested themselves in the   late 1920s is in line with the famous conjecture of Milton Friedman and Anna Schwartz (1963).”

So what policy rule are the authors talking about? Well, it is basically a feedback rule where the money base is expanded to counteract negative shocks to money-velocity in the previous period. This is not completely a NGDP targeting rule, but it is close – at least in spirit. Under NGDP level targeting the central bank will increase in the money base to counteract shocks to velocity to keep NGDP on a stable growth path. The rule suggested in the paper is a soft version of this. It could obviously be very interesting to see how a real NGDP rule would have done in the model.

Anyway, I can highly recommend the paper – especially to the members of the ECB’s The Governing Council and I see no reason that they should not implement a rule for the euro zone similar to the one suggested in the paper. If the ECB had such a rule in place then Spanish 10-year bond yields probably would not have been above 7% today.

PS Scott Sumner has been looking for a model for some time. Maybe the Christiano-Motto-Rostagno model would be something for Scott…


 

Please keep “politics” out of the monetary reaction function

During the Great Moderation it was normal to say that the Federal Reserve and the ECB (and many other central banks for that matter) was following a relatively well-defined monetary policy reaction function. It is debatable what these central banks where actually targeting, but there where is no doubt that both the Fed and the ECB overall can be descripted to have conducted monetary policy to minimize some kind of loss function which included both unemployment and inflation.

In a world where the central bank follows a Taylor rule style monetary policy reaction function, targets the NGDP level, do inflation targeting or have pegged the exchange rate the markets will tend to ignore political news. The only important thing will be how the actual economic development is relative to the target and in a situation with a credible nominal target the Chuck Norris effect will ensure that the markets do most of the lifting to achieve the nominal target.  The only things that could change that would be if politicians decided to take away the central bank’s independence and/or change the central bank’s target.

When I 12 years ago joined the financial sector from a job in the public sector I was hugely surprised by how little attention my colleagues in the bank was paying to political developments. I, however, soon learned that both fiscal policy and monetary policy in most developed countries had become highly rule based and therefore there was really no reason to pay too much attention to the nitty-gritty of day-to-day politics. The only thing one should pay attention to was whether or not given monetary targets where on track or not. That was the good old days of the Great Moderation. Monetary policy was rule based and therefore highly predictable and as a result market volatility was very low.

This have all changed in the brave new world of Great Recession (failed) monetary policy and these days it seems like market participants are doing nothing else than trying to forecast what will be the political changes in country X, Y and Z. The reason for that is the sharp increase in the politician of monetary policy.

In the old days – prior to the Great Moderation – market participants were used to have politicians messing up monetary policies. Central banks were rarely independent and did not target clear nominal targets. However, today the situation is different. Gone are the days of rule based monetary policy, but the today it is not the politicians interfering in the conduct of monetary policy, but rather the central bankers interfering in the conduct of other policies.

This particularly is the case in the euro zone where the ECB now openly is “sharing” the central bank’s view on all kind of policy matters – such as fiscal policy, bank regulation, “structural reforms” and even matters of closer European political integration. Furthermore, the ECB has quite openly said that it will make monetary policy decisions conditional on the “right” policies being implemented. It is for example clear that the ECB have indicated that it will not ease monetary policy (enough) unless the Greek government and the Spanish government will “deliver” on certain fiscal targets. So if Spanish fiscal policy is not “tight enough” for the liking of the ECB the ECB will not force down NGDP in the euro zone and as a result increase the funding problems of countries such as Spain. The ECB is open about this. The ECB call it to use “market forces” to convince governments to implement fiscal tightening. It of course has nothing to do with market forces. It is rather about manipulating market expectations to achieve a certain political outcome.

Said in another way the ECB has basically announced that it does not only have an inflation target, but also that certain political outcomes is part of its reaction function. This obviously mean that forward looking financial markets increasingly will act on political news as political news will have an impact of future monetary policy decisions from the ECB.

Any Market Monetarist will tell you that the expectational channel is extremely important for the monetary transmission mechanism and this is particularly important when a central bank start to include political outcomes in it’s reaction function.

Imaging a central bank say that it will triple the money supply if candidate A wins the presidential elections (due to his very sound fiscal policy ideas), but will cut in halve the money supply if candidate B wins (because he is a irresponsible bastard). This will automatically ensure that the opinion polls will determine monetary policy. If the opinion polls shows that candidate A will win then that will effectively be monetary easing as the market will start to price in future monetary policy easing. Hence, by announce that political outcomes is part of its reaction function will politics will make monetary policy endogenous. The ECB of course is operating a less extreme version of this set-up. Hence, it is for example very clear that the ECB’s monetary policy decisions in the coming months will dependent on the outcome of the Greek elections and on the Spanish government’s fiscal policy decisions.

The problem of course is that politics is highly unpredictable and as a result monetary policy becomes highly unpredictable and financial market volatility therefore is likely to increase dramatically. This of course is what has happened over the past year in Europe.

Furthermore, the political outcome also crucially dependents on the economic outcome. It is for example pretty clear that you would not have neo-nazis and Stalinists in the Greek parliament if the economy were doing well. Hence, there is a feedback from monetary policy to politics and back to monetary policy. This makes for a highly volatile financial environment.  In fact it is hard to see how you can achieve any form of financial or economic stability if central banks instead of targeting only nominal variables start to target political outcomes.

So I long for the days when politics was not market moves in the financial markets and I hope central banks around the world would soon learn that it is not part of their mandate to police the political process and punish governments (and voters!) for making the wrong decisions. Central banks should only target nominal targets and nothing else. If they diverge from that then things goes badly wrong and market volatility increases sharply.

Finally I should stress that I am not arguing in anyway that the ECB is wrong to be concerned about fiscal policy being unsustainable in a number of countries. I am deeply concerned about that state of fiscal policy in a number of countries and I think it is pretty clear to my regular readers that I do not favour easier fiscal policy to solve the euro zone crisis. I, however, is extremely sceptical about certain political results being included in the ECB’s reaction function. That is a recipe for increased market volatility.

PS this discussion is of course very similar to what happened during the Great Depression when politics kept slipping into the newspapers’ financial sector (See here and here)

The Jedi mind trick – Matt O’Brien’s insightful version of the Chuck Norris effect

Our friend Matt O’Brien has a great new comment on the Atlantic.com. Matt is one of the most clever commentators on monetary matters in the US media.

In Matt’s new comment he set out to explain the importance of expectations in the monetary transmission mechanism.

Here is Matt:

“These aren’t the droids you’re looking for.” That’s what Obi-Wan Kenobi famously tells a trio of less-than-with-it baddies in Star Wars when — spoiler alert! — they actually were the droids they were looking for. But thanks to the Force, Kenobi convinces them otherwise. That’s a Jedi mind trick — and it’s a pretty decent model for how central banks can manipulate expectations. Thanks to the printing press, the Fed can create a self-fulfilling reality. Even with interest rates at zero.

Central banks have a strong influence on market expectations. Actually, they have as strong an influence as they want to have. Sometimes they use quantitative easing to communicate what they want. Sometimes they use their words. And that’s where monetary policy basically becomes a Jedi mind trick.

The true nature of central banking isn’t about interest rates. It’s about making and keeping promises. And that brings me to a confession. I lied earlier. Central banks don’t really buy or sell short-term bonds when they lower or raise short-term interest rates. They don’t need to. The market takes care of it. If the Fed announces a target and markets believe the Fed is serious about hitting that target, the Fed doesn’t need to do much else. Markets don’t want to bet against someone who can conjure up an infinite amount of money — so they go along with the Fed.

Don’t underestimate the power of expectations. It might sound a like a hokey religion, but it’s not. Consider Switzerland. Thanks to the euro’s endless flirtation with financial oblivion, investors have piled into the Swiss franc as a safe haven. That sounds good, but a massively overvalued currency is not good. It pushes inflation down to dangerously low levels, and makes exports uncompetitive. So the Swiss National Bank (SNB) has responded by devaluing its currency — setting a ceiling on its value at 1.2 Swiss francs to 1 euro. In other words, the SNB has promised to print money until its money is worth what it wants it to be worth. It’s quantitative easing with a target. And, as Evan Soltas pointed out, the beauty of this target is that the SNB hasn’t even had to print money lately, because markets believe it now. Markets have moved the exchange rate to where the SNB wants it.”

This is essentially the Star Wars version of the Chuck Norris effect as formulated by Nick Rowe and myself. The Chuck Norris effect of monetary policy: You don’t have to print more money to ease monetary policy if you are a credible central bank with a credible target.

It is pretty simple. It is all about credibility. A central bank has all the powers in the world to increase inflation and nominal GDP (remember MV=PY!) and if the central bank clearly demonstrates that it will use this power to ensure for example a stable growth path for the NGDP level then it might not have to do any (additional) money printing to achieve this. The market will simply do all the lifting.

Imagine that a central bank has a NGDP level target and a shock to velocity or the money supply hits (for example due to banking crisis) then the expectation for future NGDP (initially) drops below the target level. If the central bank’s NGDP target is credible then market participants, however, will know that the central bank will react by increasing the money base until it achieves it’s target. There will be no limits to the potential money printing the central bank will do.

If the market participants expect more money printing then the country’s currency will obviously weaken and stock prices will increase. Bond yields will increase as inflation expectations increase. As inflation and growth expectations increase corporations and household will decrease their cash holdings – they will invest and consume more. The this essentially the Market Monetarist description of the monetary transmission mechanism under a fully credible monetary nominal target (See for example my earlier posts here and here).

This also explains why Scott Sumner always says that monetary policy works with long and variable leads. As I have argued before this of course only is right if the monetary policy is credible. If the monetary target is 100% credible then monetary policy basically becomes endogenous. The market reacts to information that the economy is off target. However, if the target is not credible then the central bank has to do most of the lifting itself. In that situation monetary policy will work with long and variable lags (as suggested by Milton Friedman). See my discussion of lag and leads in monetary policy here.

During the Great Moderation monetary policy in the euro zone and the US was generally credible and monetary policy therefore was basically endogenous. In that world any shock to the money supply will basically be automatically counteracted by the markets. The money supply growth and velocity tended to move in opposite directions to ensure the NGDP level target (See more on that here). In a world where the central bank is able to apply the Jedi mind trick the central bankers can use most of their time golfing. Only central bankers with no credibility have to work hard micromanaging things.

“I FIND YOUR LACK OF A TARGET DISTURBING”

So the reason European central bankers are so busy these days is that the ECB is no longer a credible. If you want to test me – just have a look at market inflation expectations. Inflation expectations in the euro zone have basically been declining for more than a year and is now well below the ECB’s official inflation target of 2%. If the ECB had an credible inflation target of 2% do you then think that 10-year German bond yields would be approaching 1%? Obviously the ECB could solve it’s credibility problem extremely easy and with the help of a bit Jedi mind tricks and Chuck Norris inflation expectations could be pegged at close to 2% and the euro crisis would soon be over – and it could do more than that with a NGDP level target.

Until recently it looked like Ben Bernanke and the Fed had nailed it (See here – once I believed that Bernanke did nail it). Despite an escalating euro crisis the US stock market was holding up quite well, the dollar did not strengthen against the euro and inflation expectations was not declining – clear indications that the Fed was not “importing” monetary tightening from Europe. The markets clearly was of the view that if the euro zone crisis escalated the Fed would just step up quantitative ease (QE3). However, the Fed’s credibility once again seems to be under pressures. US stock markets have taken a beating, US inflation expectations have dropped sharply and the dollar has strengthened. It seems like Ben Bernanke is no Chuck Norris and he does not seem to master the Jedi mind trick anymore. So why is that?

Matt has the answer:

“I’ve seen a lot of strange stuff, but nothing quite as strange as the Fed’s reluctance to declare a target recently. Rather than announce a target, the Fed announces how much quantitative easing it will do. This is planning for failure. Quantitative easing without a target is more quantitative and less easing. Without an open-ended commitment that shocks expectations, the Fed has to buy more bonds to get less of a result. It’s the opposite of what the SNB has done.

Many economists have labored to bring us this knowledge — including a professor named Ben Bernanke — and yet the Fed mostly ignores it. I say mostly, because the Fed has said that it expects to keep short-term interest rates near zero through late 2014. But this sounds more radical than it is in reality. It’s not a credible promise because it’s not even a promise. It’s what the Fed expects will happen. So what would be a good way to shift expectations? Let’s start with what isn’t a good way.”

I agree – the Fed needs to formulate a clear nominal target andit needs to formulate a clear reaction function. How hard can it be? Sometimes I feel that central bankers like to work long hours and want to micromanage things.

UPDATE: Marcus Nunes and Bill Woolsey also comments on Matt’s piece..

Dude, here is your model

Here is Scott Sumner:

“Whenever I get taunted about not having a “model,” I assume the commenter is probably younger than me, highly intelligent, but not particularly wise.”

So Scott has a problem – he does not have a fancy new model he can show off to the young guys. Well, Scott let me see if I can help you.

Here is your short-term static model:

An Eaglian (as in David Eagle) equation of exchange:

(1) N=PY

Where N is nominal GDP and P is the price level. Y is real GDP.

An Sumnerian Phillips curve:

(2) Y=Y*+a(N-NT)

Where NT is the target level for nominal GDP and N is nominal GDP . Y* is trend trend RGDP.

(1) is a definition so there can be no debate about that one. (2) is a well-established emprical fact. There is a very high correlation between Y and N in the short-run. If you need a microfoundation that’s easy – it’s called “sticky prices”.

N (and NT) is exogenous in the model and is of course determined by the central bank. And yes, yes N=MV where  M is the money and V is velocity.

In the short run P is “sticky” and N determines Y. Hence, the Sumnerian Phillips curve is upward sloping.

If you want a financial sector in the model we need to re-formulate it all in growth rates and we can introduce rational expectations. That not really overly complicated. Bond yield is a function of expected growth nominal GDP over a given period and so is stock prices.

In the long-run money is neutral so Y=Y* …so if you need a model for Y* you just go for a normal Solow growth model (or whatever you need…). I the long run the Sumnerian Phillips curve becomes vertical.

It don’t have to be more complicated than that…

That said, I think it is very important to demand to see people’s models. In fact I often challenge people to exactly spell out the model people have in their heads. That will show the inconsistencies in their arguments (the Austrian Business Cycle model is for example impossible to put on equations exactly because it is inconsistent). Mostly it turns out that people are doing national accouting economics and there is no money in their models – and if there is money in the model they do not have a explicit modeling of the central bank’s reaction function. So Scott you are certainly wrong when you tell of to get rid of the models. The problem is that far too many economists and especially central bankers are not spelling out their models and their reaction functions. I would love to see the kind of model that make the ECB think that monetary policy is easy in the euro zone…

That damn loss function

Scott further complains:

“Some general equilibrium models are used to find which stabilization policy regime is optimal from a welfare perspective.  Most of these models assume some sort of wage/price stickiness.  And 100% of the models taken seriously in the real world assume wage/price stickiness.  The problem is that there are many types of wage and price stickiness, and many ways of modeling the problem.  You can get pretty much whatever policy implication you want with the right set of assumptions.  Unfortunately, macroeconomists aren’t able to prove which model is best.  I think that’s because lots of models are partly true, and the extent to which specific assumptions are true depends on which country you are looking at, as well as which time period.  And then there’s the Lucas Critique.”

Translated this mean that implicit in most New Keynesian models is a assumption about the the central bank minimizing some sort of “loss function”. The problem with that is that assumes that there is some kind of representative agent. In terms of welfare analysis of monetary policy rules that is a massive problem – any Austrian economist would (rightly) tell you so and so would David Eagle. See my earlier post on the that damn “loss function” here.

Scott has one more complaint:

“To summarize, despite all the advances in modern macro, there is no model that anyone can point to that “proves” any particular policy target is superior to NGDPLT.  There might be a superior target (indeed I suspect a nominal wage target would be superior.)  But it can’t be shown with a model.  All we can do is construct a model that has that superiority built in by design.”

Scott, I am disappointed. Haven’t you read the insights of David Eagle? David has done excellent work on why NGDPLT Pareto dominates Price Level Targeting and inflation targeting. See here and here and here. Evan Koeing of course makes a similar point. And yes, neither David nor Evan use a “loss function”. They use proper welfare theory.

Anyway, no reason to be worried about models – they just need to be the right ones and the biggest complaint against most New Keynesian models is the problematic assumption about the representative agent. And then of course New Keynesian models have a very rudimentary formulation of asset markets, but that is easy to get around.

PS I am sure Scott would not disagree with much what I just wrote and I am frankly as frustrated with “models” that are used exactly because they are fancy rather because they make economic sense.
