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.

Udpate 3: Also comments from David Glasner, Marcus Nunes and Bill Woolsey.

Imagine that a S&P500 future was the Fed’s key policy tool

Here is Yale economics professor Stephen Roach:

“The ECB is pretty much out of ammunition.”

This sentence probably best illustrates what is wrong with monetary policy thinking in today’s world. Obviously the ECB is not out of ammunition, but Roach’s perception is very common.

What Roach fails to realise is that when central banks announce what we in general terms could call the “key policy rate” it is really just announcing a intermediate target for a given market interest rate. What the central bank actually is doing it setting the money base to fix a given market interest rate at a given level. In that sense the interest rates is merely a tool for communication. Nothing else.

The problem is that in most standard macroeconomic models the central bank does not determine the money base – in fact there is no money in most of today’s mainstream macroeconomic models – but rather the “interest rate”. In a world where interest rates are well above zero that is not a major problem, but when the key policy rate gets close to zero you get a communication problem. However, this is really only a perceived problem rather than an actual problem. The central bank can always expand the money base – also if the key policy rate is zero or close to zero.

The mental problem really is that interest rates have replaced money in today’s mainstream (mostly New Keynesian) macroeconomic models. Lets therefore imagine that we constructed a simple macroeconomic model where there is no interest rate, but where the central bank’s communication tool is stock prices or rather stock futures.

Many economists would willingly accept that stock prices can influence both private consumption (through a wealth effect) and investments (through a funding cost effect) and as such that would not be different from the “normal” assumption about how interest rates influence domestic demand. Therefore, by influencing the stock prices the central bank would be able to influence domestic demand. Note of course that I on purpose am “keynesian” in my rhetoric just to make my point in regard to mainstreaming thinking of monetary policy. (Obviously stock prices as well and private consumption and investments are determined by expectations of future nominal income.)

Then now imagine that the central bank every month announces a certain level for the a stock market future instead of announcing a key policy interest rate. So for example in the case of the Federal Reserve the FOMC would every month announce a “target” for a given S&P500 future.

Would anybody question that the Fed could do this? And would anybody question whether the Fed could hit that target? No, of course not. The ECB obviously could do the exact same thing. There would be absolutely no technical problem in using stock prices (or rather stock futures) as a policy instrument.

Do you think Stephen Roach would argue that the ECB “pretty much” was out of ammunition had just increased it’s target for the Euronext 24 month future with 5%? No of course not and that in my view clearly illustrates that the zero bound on interest rates only is a mental problem, but an actual problem.

Finally note that I am not advocating that central banks should target stock prices (I advocate they should target an NGDP future), but I see little difference in such a policy instrument and interest rate targeting. Furthermore, there would not be a zero bound problem if the Fed was targeting S&P500 futures rather than interest rates and Stephen Roach might even realise that the ECB in no way is out of ammunition.

——

PS over the long run NGDP and stock prices are actually quite strongly correlated and hence if the Fed announced that S&P500 should increase by lets say 5% a year over the coming 5 years and that it would ensure that by buying (or selling) S&P futures then it would probably do a much better job at hitting a given level of NGDP or inflation for that matter than the Fed’s present weird policy of promising to keep interest rates low for longer or the silly operation twist.

PPS I am pretty sure that Stephen Roach full well knows that the ECB is not out of ammunition, but when you talk to journalists you might make some intellectual short-cuts that distorts what you really think. At least I hope that is what happened.

PPPS If the Fed wanted to target the NGDP level then it is pretty easy to construct indicator for future NGDP from S&P500 futures, TIPS inflation expectations, CRB futures and the nominal effective dollar rate and then the Fed could just use that as a communication tool. Then it would never ever again have to talk about QE or running out of ammunition.

The Fed can hit any NGDP target

I hate getting into debates where different bloggers go back and forth forever and never reach any conclusion. I am not blogging to get into debates, however, I must admit that Steven Williamson’s recent posts on NGDP level targeting have provoked me quite a bit.

In his first post Williamson makes a number of claims, which I find highly flawed. However, Scott Sumner has already at length addressed most of these issues in a reply to Williamson so I don’t want to get into that (and as you guessed I am fully in agreement with Scott). However, Williamson’s reply to Scott is not less flawed than his initial post. Again I don’t want to go through the whole thing. However, one statement that Williamson makes I think is a very common mistake and I therefore think a comment is in order. Here is Williamson:

“The key problem under the current circumstances is that you can’t just announce an arbitrary NGDP target and hit it with wishful thinking. The Fed needs some tools, and in spite of what Ben Bernanke says, it doesn’t have them.”

This is a very odd comment coming from somebody who calls himself a (New) Monetarist. It is at the core of monetarism in the sense of Friedman, Brunner, Meltzer, Cagan, Schwartz, Warburton and Yeager etc. that nominal GDP is determined by the central bank and no monetarist has ever acknowledged that there is a liquidity trap. Williamson claims that he does not agree with everything Friedman said, but I wonder what Friedman said he agrees with. If you don’t believe that NGDP is determined by the central bank then it makes absolutely no sense to call yourself a monetarist.

Furthermore, if you don’t think that the Fed can hit an NGDP target how could you think it could hit an inflation target? Both changes in NGDP and in prices are monetary phenomena.

Anyway, let’s get back to the question whether the central bank can hit an NGDP target and what instruments could be used to hit that target.

The simplest way to do it is actually to use the exchange rate channel. Let’s assume that the Federal Reserve wants to increase the US NGDP level by 15% and that it wants to do it by the end of 2013.

Scott has suggested using NGDP futures to hit the NGDP target, but let’s assume that is too complicated to understand for the critics and the Fed. Instead the Fed will survey professional forecasters about their expectations for the level of NGDP by the end of 2013. The Fed will then announce that as long as the “consensus” forecast for NGDP is below the target the Fed will step up monetary easing. The Fed will do the survey once a month.

Let’s start out with the first announcement under this new regime. Initially the forecasters are skeptical and forecast NGDP to be 12% below target. As a consequence the Fed announces a Swiss style exchange target. It simply announces that it will intervene in the FX market buying unlimited amounts of foreign currency until the US dollar has weakened 20% in nominal effective terms (and yes, the Fed has the instruments to do that – it has the printing press to print dollars). I am pretty sure that Williamson would agree that that directly would increase US NGDP (if not I would love to see his model…).

The following month the forecasters will likely have moved their forecasts for NGDP closer to the target level. But we might still have too low a level of forecasted NGDP. Therefore, the Fed will the following month announce a further “devaluation” by lets say 5%. The process will continue until the forecasted level for NGDP equals the target level. If the consensus forecast starts to overshoot the target the Fed will simply announce that it will reverse the process and revalue the dollar.

Therefore there is certainly no reason to argue 1) that the Fed can not hit any NGDP target 2) that the Fed does not have an instrument. The exchange rate channel can easily do the job. Furthermore, if the Fed announces this policy then it is very likely that the market will be doing most of the lifting. The dollar would automatically appreciate and depreciate until the market expectations are equal to the NGDP target.

If you have heard all this before then it is because this a variation of Irving Fisher’s compensated dollar plan and Lars E. O. Svensson’s foolproof way out of a liquidity trap. And yes, I have previously suggested this for small open economies, but the Fed could easily use the same method to hit a given NGDP target.

Update: I should note that the example above is exactly that – an example. I use the example to illustrate that a central bank can always increase NGDP and that the exchange rate channel is an effective tool to achieve this goal. However, the numbers mentioned in my post are purely “fictional” and again it example rather than a policy recommendation. That said, I am pretty that if the Fed did exactly as what I suggest above the US would very fast bee out of this crisis. The same goes for the ECB.

Update II: Marcus Nunes and Bill Woolsey also comment on Williamson. Nick Rowe comments on David Adolfatto’s anti-NGDP targeting post(s).

Jeff Frankel restates his support for NGDP targeting

It is no secret that I have been fascinated by some of Havard professor Jeff Frankel’s ideas especially his idea for Emerging Markets commodity exporters to peg the currency to the price of their main export (PEP). I have written numerous posts on this (see below) However, Frankel is also a long-time supporter of NGDP target and now he has restated is his views on NGDP targeting.

Here is Jeff:

“In my preceding blogpost, I argued that the developments of the last five years have sharply pointed up the limitations of Inflation Targeting (IT), much as the currency crises of the 1990s dramatized the vulnerability of exchange rate targeting and the velocity shocks of the 1980s killed money supply targeting.   But if IT is dead, what is to take its place as an intermediate target that central banks can use to anchor expectations?

The leading candidate to take the position of preferred nominal anchor is probably Nominal GDP Targeting.  It has gained popularity rather suddenly, over the last year.  But the idea is not new.  It had been a candidate to succeed money targeting in the 1980s, because it did not share the latter’s vulnerability to shifts in money demand.  Under certain conditions, it dominates not only a money target (due to velocity shocks) but also an exchange rate target  (if exchange rate shocks are large) and a price level target (if supply shocks are large).   First proposed by James Meade (1978), it attracted the interest in the 1980s of such eminent economists as Jim Tobin (1983), Charlie Bean(1983), Bob Gordon (1985), Ken West (1986), Martin Feldstein & Jim Stock (1994), Bob Hall & Greg Mankiw (1994), Ben McCallum (1987, 1999), and others.

Nominal GDP targeting was not adopted by any country in the 1980s.  Amazingly, the founders of the European Central Bank in the 1990s never even considered it on their list of possible anchors for euro monetary policy.  (They ended up with a “two pillar approach,” of which one pillar was supposedly the money supply.)” 

So far so good…and here is something, which will make all of us blogging Market Monetarists happy:

“But now nominal GDP targeting is back, thanks to enthusiastic blogging by ScottSumner (at Money Illusion), LarsChristensen (at Market Monetarist), David Beckworth (at Macromarket Musings),Marcus Nunes (at Historinhas) and others.  Indeed, the Economist has held up the successful revival of this idea as an example of the benefits to society of the blogosphere.”

This is a great endorsement of the Market Monetarist “movement” and it is certainly good news that Jeff so clearly recognize the work of the blogging Market Monetarists. Anyway back to the important points Jeff are making.

“Fans of nominal GDP targeting point out that it would not, like Inflation Targeting, have the problem of excessive tightening in response to adverse supply shocks.    Nominal GDP targeting stabilizes demand, which is really all that can be asked of monetary policy.  An adverse supply shock is automatically divided between inflation and real GDP, equally, which is pretty much what a central bank with discretion would do anyway.

In the long term, the advantage of a regime that targets nominal GDP is that it is more robust with respect to shocks than the competitors (gold standard, money target, exchange rate target, or CPI target).   But why has it suddenly gained popularity at this point in history, after two decades of living in obscurity?  Nominal GDP targeting might also have another advantage in the current unfortunate economic situation that afflicts much of the world:  Its proponents see it as a way of achieving a monetary expansion that is much-needed at the current juncture.”

Exactly! The great advantage of NGDP level targeting compared to other monetary policy rules is that it handles both velocity shocks and supply shocks. No other rules (other than maybe Jeff’s own PEP) does that. Furthermore, I would add something, which is tremendously important to me and that is that unlike any other monetary policy rule NGDP level targeting does not distort relative prices. NGDP level targeting as such ensures the optimal and unhampered working of a free market economy.

Back to Jeff:

“Monetary easing in advanced countries since 2008, though strong, has not been strong enough to bring unemployment down rapidly nor to restore output to potential.  It is hard to get the real interest rate down when the nominal interest rate is already close to zero. This has led some, such as Olivier Blanchard and Paul Krugman, to recommend that central banks announce a higher inflation target: 4 or 5 per cent.   (This is what Krugman and Ben Bernanke advised the Bank of Japan to do in the 1990s, to get out of its deflationary trap.)  But most economists, and an even higher percentage of central bankers, are loath to give up the anchoring of expected inflation at 2 per cent which they fought so long and hard to achieve in the 1980s and 1990s.  Of course one could declare that the shift from a 2 % target to 4 % would be temporary.  But it is hard to deny that this would damage the long-run credibility of the sacrosanct 2% number.   An attraction of nominal GDP targeting is that one could set a target for nominal GDP that constituted 4 or 5% increase over the coming year – which for a country teetering on the fence between recovery and recession would in effect supply as much monetary ease as a 4% inflation target – and yet one would not be giving up the hard-won emphasis on 2% inflation as the long-run anchor.”

I completely agree. I have always found the idea of temporary changing the inflation target to be very odd. The problem is not whether to target 2,3 or 4% inflation. The problem is the inflation targeting itself. Inflation targeting tends to create bubbles when the economy is hit by positive supply shocks. It does not fully response to negative velocity shocks and it leads to excessive tightening of monetary policy when the economy is hit by negative supply shocks (just have look at the ECB’s conduct of monetary policy!)
Market Monetarists advocate a clear rule based monetary policy exactly because we think that expectations is tremendously important in the monetary transmission mechanism. A temporary change in the inflation target would completely undermining the effectiveness of the monetary transmission mechanism and we would still be left with a bad monetary policy rule.
Let me give the final word to Jeff:
Thus nominal GDP targeting could help address our current problems as well as a durable monetary regime for the future.

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..

Jens Weidmann, do you remember the second pillar?

Today the ECB is very eager to stress it’s 2% inflation target. However, a couple of years ago the ECB in fact had two targets – the so-called two pillars of monetary policy. The one was the inflation target and the other was a money supply target – the so-called reference value for the growth rate of M3.

The second pillar in many ways made a lot of sense – at least as a instrument for monetary analysis. The second pillar was put into the ECB tool box by the Bundesbank which insisted that monetary analysis was as important as a pure inflation target. Read for example former ECB chief economist and Bundesbanker Otmar Issing’s defense of the two-pillar set-up here.

The starting point for calculating the reference value for M3 was the equation of exchange:

(1) MV=PY

or in growth rates:

(2) m+v=p+y

(2) of course can be re-written to:

(2)’ m=p+y-v

If we assume trend real GDP growth (y) is 2% you can calculate the reference value for m that will ensure 2% inflation over the medium term. You of course also have to make an assumption about velocity. ECB used to think that trend growth in v was -0.5 to -1%.

This give us the following reference growth rate for M3 (m-target):

(3) m-target=2+2-(-1)=5% (4.5% if you assume velocity growth of -0.5%)

Said in another way if the ECB keeps M3 growing at 5% year-in and year-out then inflation should be around 2% in the medium term. An yes, this is of course exactly what Milton Friedman recommend long ago.

2.5% M3 growth is hardly inflationary

Today we got the latest M3 numbers for the euro zone. The calvinists should be happy – M3 decelerated sharply to 2.5% y/y in April. Half of what should be the reference growth rate for M3 – and that is ignoring the fact that velocity has collapsed.

What does that tells us about the inflationary risks in the euro zone? Well, there are no inflationary risks – there are only deflationary risks.

Using the assumptions above we can calculate the long-term inflation if M3 keeps growing by 2.5% – from (2)’ we get the following:

(4) p=m-y+v

(4)’ p=2.5-2+(-1)=-0.5%

So it is official! Monetary analysis as it used to be conducted in the Bundesbank is telling you that we are going to have deflation in the euro zone in the medium term! And don’t tell me about monetary overhang – the ECB is in the business of letting bygones be bygones (otherwise the ECB would target the NGDP LEVEL or the price LEVEL) and by the way the ECB spend lots of time in 2004-7 to explain why money supply growth overshot the target.

Jens Weidmann – monetarist or calvinist?

The Bundesbank brought in monetary analysis and a money supply focus to the ECB so I think it is only fair to ask whether Bundesbank chief Jens Weidmann still believe in monetary analysis? If he is true to the strong monetarist traditions at the Bundesbank then he should come out forcefully in favour of monetary easing to ensure M3 growth of at least 5% – in fact it should be much higher as velocity has collapsed, but at least to bring M3 back to 5% would be a start.

I hope the Bundesbank will soon refind it’s monetarist traditions…please make Milton Friedman and Karl Brunner proud!

PS I of course still want the ECB to introduce a NGDP level target, but less would make me happy – a 5-10% target range for M3 (the range prior to the crisis) and a minimum price on European inflation linked bonds would would clearly be enough to at least avoid collapse.

Hear, hear!! Beckworth’s and Ponnuru’s call for monetary regime change

When you are blogging you will often find yourself quote other bloggers and commentators. Mostly just four or fives lines. However, this time around I am not going to quote anything from David Beckworth’s and Ramesh’s latest article in National Review. So why is that? Well, I simply agrees strongly with EVERYTHING the two gentlemen write in their article and I can’t quote the whole thing. It is simply an excellent piece on why the Federal Reserve and the ECB should switch to NGDP level targeting. If this will not convince you nothing will.

So instead of quoting the whole thing, but you better just go directly to National Review and have a look. That said, I would love to hear what my readers think of the article.

HT dwb

PS While we are at it – here is one more reading recommendation – have a look at Matt O’Brien’s latest story on Spain. I wonder if we would have been here is the ECB had been targeting the NGDP level. No chance!

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.

Monetary disorder – not animal spirits – caused the Great Recession

If one follows the financial media on a daily basis as I do there is ample room to get both depressed and frustrated over the coverage of the financial markets. Often market movements are described as being very irrational and the description of what is happening in the markets is often based on an “understanding” of economic agents as somebody who have huge mood swings due to what Keynes termed animal spirits.

Swings in the financial markets created by these animal spirits then apparently impact the macroeconomy through the impact on investment and private consumption. In this understanding markets move up and down based on rather irrational mood swings among investors. This is what Robert Hetzel has called the “market disorder”-view. It is market imperfections and particularly the animal spirits of investors which created swings not only in the markets, but also in the financial markets. Bob obviously in his new book convincingly demonstrates that this “theory” is grossly flawed and that animal spirits is not the cause of neither the volatility in the markets nor did animal spirits cause the present crisis.

The Great Recession is a result of numerous monetary policy mistakes – this is the “monetary disorder”-view – rather than a result of irrational investors behaving as drunken fools. This is very easy to illustrate. Just have a look first at S&P500 during the Great Recession.

The 6-7 phases of the Great Recession – so far

We can basically spot six or seven overall phases in S&P500 since the onset of the crisis. In my view all of these phases or shifts in “market sentiment” can easy be shown to coincide with monetary policy changes from either the Federal Reserve or the ECB (or to some extent also the PBoC).

We can start out with the very unfortunate decision by the ECB to hike interest rates in July 2008. Shortly after the ECB hike the S&P500 plummeted (and yes, yes Lehman Brother collapses in the process). The free fall in S&P500 was to some extent curbed by relatively steep interest rate reductions in the Autumn of 2008 from all of the major central banks in the world. However, the drop in the US stock markets did not come to an end before March 2009.

March-April 2009: TAF and dollar swap lines

However, from March-April 2009 the US stock markets recovered strongly and the recovery continued all through 2009. So what happened in March-April 2009? Did all investors suddenly out of the blue become optimists? Nope. From early March the Federal Reserve stepped up its efforts to improve its role as lender-of-last resort. The de facto collapse of the Fed primary dealer system in the Autumn of 2008 had effective made it very hard for the Fed to function as a lender-of-last-resort and effectively the Fed could not provide sufficient dollar liquidity to the market. See more on this topic in George Selgin’s excellent paper  “L Street: Bagehotian Prescriptions for a 21st-Century Money Market”.

Here especially the two things are important. First, the so-called Term Auction Facility (TAF). TAF was first introduced in 2007, but was expanded considerably on March 9 2009. This is also the day the S&P500 bottomed out! That is certainly no coincidence.

Second, on April 9 when the Fed announced that it had opened dollar swap lines with a number of central banks around the world. Both measures significantly reduced the lack of dollar liquidity. As a result the supply of dollars effectively was increased sharply relatively to the demand for dollars. This effectively ended the first monetary contraction during the early stage of the Great Recession and the results are very visible in S&P500.

This as it very clear from the graph above the Fed’s effects to increase the supply of dollar liquidity in March-April 2009 completely coincides with the beginning of the up-leg in the S&P500. It was not animal spirits that triggered the recovery in S&P500, but rather easier monetary conditions.

January-April 2010: Swap lines expiry, Chinese monetary tightening and Fed raises discount rate

The dollar swap lines expired February 1 2010. That could hardly be a surprise to the markets, but nonetheless this seem to have coincided with the S&P500 beginning to loose steam in the early part of 2010. However, it was probably more important that speculation grew in the markets that global central banks could move to tighten monetary conditions in respond to the continued recovery in the global economy at that time.

On January 12 2010 the People’s Bank of China increased reserve requirements for the Chinese banks. In the following months the PBoC moved to tighten monetary conditions further. Other central banks also started to signal future monetary tightening.

Even the Federal Reserve signaled that it might be reversing it’s monetary stance. Hence, on February 18 2010 the Fed increased the discount rate by 25bp. The Fed insisted that it was not monetary tightening, but judging from the market reaction it could hardly be seen by investors as anything else.

Overall the impression investors most have got from the actions from PBoC, the Fed and other central banks in early 2010 was that the central banks now was moving closer to initiating monetary tightening. Not surprisingly this coincides with the S&P500 starting to move sideways in the first half of 2010. This also coincides with the “Greek crisis” becoming a market theme for the first time.

August 27 2010: Ben Bernanke announces QE2 and stock market takes off again

By mid-2010 it had become very clear that talk of monetary tightening had bene premature and the Federal Reserve started to signal that a new round of monetary easing might be forthcoming and on August 27 at his now famous Jackson Hole speech Ben Bernanke basically announced a new round quantitative easing – the so-called QE2. The actual policy was not implemented before November, but as any Market Monetarist would tell you – it is the Chuck Norris effect of monetary policy: Monetary policy mainly works through expectations.

The quasi-announcement of QE2 on August 27 is pretty closely connected with another up-leg in S&P500 starting in August 2010. The actual upturn in the market, however, started slightly before Bernanke’s speech. This is probably a reflection that the markets started to anticipate that Bernanke was inching closer to introducing QE2. See for example this news article from early August 2010. This obviously is an example of Scott Sumner’s point that monetary policy works with long and variable leads. Hence, monetary policy might be working before it is actually announced if the market start to price in the action beforehand.

April and July 2011: The ECB’s catastrophic rate hikes

The upturn in the S&P500 lasted the reminder of 2010 and continued into 2011, but commodity prices also inched up and when two major negative supply shocks (revolutions in Northern Africa and the Japanese Tsunami) hit in early 2011 headline inflation increased in the euro zone. This triggered the ECB to take the near catastrophic decision to increase interest rates twice – once in April and then again in July. At the same time the ECB also started to scale back liquidity programs.

The market movements in the S&P500 to a very large extent coincide with the ECB’s rate hikes. The ECB hiked the first time on April 7. Shortly there after – on April 29 – the S&P500 reached it’s 2011 peak. The ECB hiked for the second time on July 7 and even signaled more rate hikes! Shortly thereafter S&P500 slumped. This obviously also coincided with the “euro crisis” flaring up once again.

September-December 2011: “Low for longer”, Operation twist and LTRO – cleaning up your own mess

The re-escalation of the European crisis got the Federal Reserve into action. On September 9 2011 the FOMC announced that it would keep interest rates low at least until 2013. Not exactly a policy that is in the spirit of Market Monetarism, but nonetheless a signal that the Fed acknowledged the need for monetary easing. Interestingly enough September 9 2011 was also the date where the three-month centered moving average of S&P500 bottomed out.

On September 21 2011 the Federal Reserve launched what has come to be known as Operation Twist. Once again this is certainly not a kind of monetary operation which is loved by Market Monetarists, but again at least it was an signal that the Fed acknowledged the need for monetary easing.

The Fed’s actions in September pretty much coincided with S&P500 starting a new up-leg. The recovery in S&P500 got further imputes after the ECB finally acknowledged a responsibility for cleaning up the mess after the two rate hikes earlier in 2011 and on December 8 the ECB introduced the so-called 3-year longer-term refinancing operations (LTRO).

The rally in S&P500 hence got more momentum after the introduction of the 3-year LTRO in December 2011 and the rally lasted until March-April 2012.

The present downturn: Have a look at ECB’s new collateral rules

We are presently in the midst of a new crisis and the media attention is on the Greek political situation and while the need for monetary policy easing in the euro zone finally seem to be moving up on the agenda there is still very little acknowledgement in the general debate about the monetary causes of this crisis. But again we can explain the last downturn in S&P500 by looking at monetary policy.

On March 23 the ECB moved to tighten the rules for banks’ use of assets as collateral. This basically coincided with the S&P500 reaching its peak for the year so far on March 19 and in the period that has followed numerous European central bankers have ruled out that there is a need for monetary easing (who are they kidding?)

Conclusion: its monetary disorder and not animal spirits

Above I have tried to show that the major ups and downs in the US stock markets since 2008 can be explained by changes monetary policy by the major central banks in the world. Hence, the volatility in the markets is a direct consequence of monetary policy failure rather than irrational investor behavior. Therefore, the best way to ensure stability in the financial markets is to ensure nominal stability through a rule based monetary policy. It is time for central banks to do some soul searching rather than blaming animal spirits.

This in no way is a full account of the causes of the Great Recession, but rather meant to show that changes in monetary policy – rather than animal spirits – are at the centre of market movements over the past four years. I have used the S&P500 to illustrate this, but a similar picture would emerge if the story was told with US or German bond yields, inflation expectations, commodity prices or exchange rates.
