Rerun: Daylight saving time and NGDP targeting

Today I got up one hour later than normal. The reason is the same as for most other Europeans this morning – the last Sunday of October – we move our clocks back one hour due to the end of Daylight saving time (summertime).

That reminded me of Milton Friedman’s so-called Daylight saving argument for floating exchange rates. According to Friedman, the argument in favour of flexible exchange rates is in many ways the same as that for summertime. Instead of changing the clocks to summertime, everyone could instead “just” change their behaviour: meet an hour later at work, change programme times on the TV, let buses and trains run an hour later, etc. The reason we do not do this is precisely because it is easier and more practical to put clocks an hour forward than to change everyone’s behaviour at the same time. It is the same with exchange rates, one can either change countless prices or change just one – the exchange rate.

There is a similar argument in favour of NGDP level targeting. Lets illustrate it with the equation of exchange.

M*V=P*Y

P*Y is of course the same as NGDP the equation of exchange can also be written as

M*V=NGDP

What Market Monetarists are arguing is that if we hold NGDP constant (or it grows along a constant path) then any shock to velocity (V) should be counteracted by an increase or decrease in the money supply (M).

Obviously one could just keep M constant, but then any shock to V would feed directly through to NGDP, but NGDP is not “one number” – it is in fact made up of countless goods and prices. So an “accommodated” shock to V in fact necessitates changing numerous prices (and volumes for the matter). By having a NGDP level target the money supply will do the adjusting instead and no prices would have to change. Monetary policy would therefore by construction be neutral – as it would not influence relative prices and volumes in the economy.

This is of course also similar to Milton Friedman’s analogy of monetary policy being like setting a thermostat (HT David Beckworth).

The conclusion therefore is that when you read Friedman’s “The Case for Floating Exchange Rates” then try think instead of “The Case for NGDP Level Targeting” – it is really the same story.

See my posts on Friedman’s arguments for floating exchange rates:

Milton Friedman on exchange rate policy #2

PS Do you remember reading this before then you are right – this is a rerun of what I wrote exactly a year ago.

Dangerous bubble fears

Here is Swedish central bank governor Stefan Ingves in an op-ed piece in the Swedish newspaper Svenska Dagbladet last week:

“I also have to take responsibility for the long term consequences of today’s monetary policy…And there are risks associated with an all too low interest rate over a long period, which cannot be ignored.”

Said in another way if we keep interest rates too low we will get bubbles. So despite very clear signs that the Swedish economy is slowing Ingves would not like to ease monetary policy. Ingves in that sense is similar to many central bankers around the world. Many central bankers have concluded that the present crisis is a result of a bubble that bursted and the worst you could do is to ease monetary policy – even if the economic data is telling you that that is exactly what you should.

The sentiment that Ingves is expressing is similar to the view of the ECB and the fed in 2008/9: We just had a bubble and if we ease too aggressively we will get another one. Interestingly enough those central banks that did well in 2008/9 and eased monetary policy more aggressively and therefore avoided major crisis today seem to be most fearful about “bubbles”. Take the Polish central bank (NBP). The NBP in 2009 allowed the zloty to weaken significantly and cut interest rates sharply. That in my view saved the Polish economy from recession in 2009 – Poland was the only country in Europe with positive real GDP growth in 2009. However, today the story is different. NBP hiked interest rates earlier in the year and is now taking very long time in easing monetary policy despite very clear signs the Polish economy is slowing quite fast. In that sense you can say the NBP has failed this year because it did so well in 2009.

The People’s Bank of China in many ways is the same story – the PBoC eased monetary policy aggressively in 2009 and that pulled the Chinese economy out of the crisis very fast, but since 2010 the PBoC obviously has become fearful that it had created a bubble – which is probably did. To me Chinese monetary policy probably became excessively easy in early 2010 so it was right to scale back on monetary easing, but money supply growth has slowed very dramatically in the last two years and monetary policy now seem to have become excessively tight.

So the story is the same in Sweden, Poland and China. The countries that escaped the crisis did so by easing monetary conditions. As their exports collapsed domestic demand had to fill the gap and easier monetary policy made that possible. So it not surprising that these countries have seen property prices continuing to increase during the last four years and also have seen fairly strong growth in private consumption and investments. However, this now seem to be a major headache for central bankers in these countries.

I think these bubble fears are quite dangerous. It was this kind of fears that led the fed and the ECB to allow monetary conditions to become excessive tight in 2008/9. Riksbanken, NBP and the PBoC now risk making the same kind of mistake.

At the core of this problem is that central bankers are trying to concern themselves with relative prices. Monetary policy is very effective when it comes to determine the price level or nominal GDP, but it is also a very blunt instrument. Monetary policy cannot – and certainly should not – influence relative prices. Therefore, the idea that the central bank should target for example property prices in my view is quite a unhealthy suggestion.

Obviously I do not deny that overly easy monetary policy under certain circumstances can lead to the formation of bubbles, but it should not be the job of central bankers to prick bubbles.

The best way to avoid that monetary policy do not create bubbles is that the central bank has a proper monetary target such as NGDP level targeting. Contrary to inflation targeting where positive supply shocks can lead to what Austrians call relative inflation there is not such a risk with NGDP level targeting.

Let’s assume that the economy is hit by a positive supply shock – for example lower import prices. That would push down headline inflation. An inflation targeting central bank – like Riksbanken and NBP – in that situation would ease monetary policy and as a result you would get relative inflation – domestic prices would increase relative to import prices and that is where you get bubbles in the property markets. Under NGDP level targeting the central bank would not ease monetary policy in response to a positive supply shock and inflation would drop ease, but the NGDP level would on the other hand remain on track.

However, the response to a demand shock – for example a drop in money velocity – would be symmetric under NGDP level targeting and inflation target. Both under IT and NGDP targeting the central bank would ease monetary policy. However, this is not what central banks that are concerned about “bubbles” are doing. They are trying to target more than one target. The first page in the macroeconomic textbook, however, tells you that you cannot have more policy targets than policy instruments. Hence, if you target a certain asset price – like property prices – it would mean that you effectively has abandoned your original target – in the case of Riksbanken and NBP that is the inflation target. So when governor Ingves express concern about asset bubbles he effective has said that he for now is not operating an inflation targeting regime. I am sure his colleague deputy governor Lars E. O. Svensson is making that argument to him right now.

I don’t deny that bubbles exist and I am not claiming that there is no bubbles in the Swedish, Polish or Chinese economies (I don’t know the answer to that question). However, I am arguing that monetary policy is a very bad instrument to “fight” bubbles. Monetary policy should not add to the risk of bubbles, but “bubble fighting” should not be the task of the central bank. The central bank should ensure nominal stability and let the market determine relative prices in the economy. Obviously other policies – such as tax policy or fiscal policy should not create moral hazard problems through implicit or explicit guarantees to “bubble makers”.

Japan has been in a 15 year deflationary environment with falling asset prices and a primary reason for that is the Bank of Japan’s insane fear of creating bubbles. I doubt that the Riksbank, NBP or the PBoC will make the same kind of mistakes, but bubbles have clearly led all three central banks to become overly cautious and as a result the Swedish, the Polish and the Chinese economy are now cooling too much.

I should stress that I do not suggest some kind of “fine tuning” policy, but rather I suggest that central banks should focus on one single policy target – and I prefer NGDP level targeting – and leave other issues to other policy makers. If central banks are concerned about bubbles they should convince politicians to implement policies that reduce moral hazard rather than trying to micromanage relative prices and then of course focus on a proper and forward looking monetary policy target like NGDP level targeting.

PS Note that I did not mention the interest rate fallacy, but I am sure Milton Friedman would have told governor Ingves about it.

The counterfactual US inflation history – the case of NGDP targeting

Opponents of NGDP level targeting often accuse Market Monetarists of being “inflationists” and of being in favour of reflating bubbles. Nothing could be further from the truth – in fact we are strong proponents of sound money and nominal stability. I will try to illustrate that with a simple thought experiment.

Imagine that that the Federal Reserve had a strict NGDP level targeting regime in place for the past 20 years with NGDP growing 5% year in and year out. What would inflation then have been?

This kind of counterfactual history excise is obviously not easy to conduct, but I will try nonetheless. Lets start out with a definition:

(1) NGDP=P*RGDP

where NGDP is nominal GDP, RGDP is real GDP and P is the price level. It follows from (1) that:

(1)’ P=NGDP/RGDP

In our counterfactual calculation we will assume the NGDP would have grown 5% year-in and year-out over the last 20 years. Instead of using actual RGDP growth we RGDP growth we will use data for potential RGDP as calculated Congressional Budget Office (CBO) – as the this is closer to the path RGDP growth would have followed under NGDP targeting than the actual growth of RGDP.

As potential RGDP has not been constant in the US over paste 20 years the counterfactual inflation rate would have varied inversely with potential RGDP growth under a 5% NGDP targeting rule. As potential RGDP growth accelerates – as during the tech revolution during the 1990s – inflation would ease. This is obviously contrary to inflation targeting – where the central bank would ease monetary policy in response to higher potential RGDP growth. This is exactly what happened in the US during the 1990s.

The graph below shows the “counterfactual inflation rate” (what inflation would have been under strict NGDP targeting) and the actual inflation rate (GDP deflator).

The graph fairly clearly shows that actual US inflation during the Great Moderation (from 1992 to 2007 in the graph) pretty much followed an NGDP targeting ideal. Hence, inflation declined during the 1990s during the tech driven boost to US productivity growth. From around 2000 to 2007 inflation inched up as productivity growth slowed.

Hence, during the Great Moderation monetary policy nearly followed an NGDP targeting rule – but not totally.

At two points in time actual inflation became significantly higher than it would have been under a strict NGDP targeting rule – in 1999-2001 and 2004-2007.

This of course coincides with the two “bubbles” in the US economy over the past 20 years – the tech bubble in the late 1990s and the property bubble in the years just prior to the onset of the Great Recession in 2008.

Market Monetarists disagree among each other about the extent of bubbles particularly in 2004-2007. Scott Sumner and Marcus Nunes have stressed that there was no economy wide bubble, while David Beckworth argues that too easy monetary policy created a bubble in the years just prior to 2008. My own position probably has been somewhere in-between these two views. However, my counterfactual inflation history indicates that the Beckworth view is the right one. This view also plays a central role in the new Market Monetarist book “Boom and Bust Banking: The Causes and Cures of the Great Recession”, which David has edited. Free Banking theorists like George Selgin, Larry White and Steve Horwitz have a similar view.

Hence, if anything monetary policy would have been tighter in the late 1990s and and from 2004-2008 than actually was the case if the fed had indeed had a strict NGDP targeting rule. This in my view is an illustration that NGDP seriously reduces the risk of bubbles.

The Great Recession – the fed’s failure to keep NGDP on track 

According to the CBO’s numbers potential RGDP growth started to slow in 2007 and had the fed had a strict NGDP targeting rule at the time then inflation should have been allowed to increase above 3.5%. Even though I am somewhat skeptical about CBO’s estimate for potential RGDP growth it is clear that the fed would have allowed inflation to increase in 2007-2008. Instead the fed effective gave up 20 years of quasi NGDP targeting and as a result the US economy entered the biggest crisis after the Great Depression. The graph clearly illustrates how tight monetary conditions became in 2008 compared to what would have been the case if the fed had not discontinued the defacto NGDP targeting regime.

So yes, Market Monetarists argue that monetary policy in the US became far too tight in 2008 and that significant monetary easing still is warranted (actual inflation is way below the counterfactual rate of inflation), but Market Monetarists – if we had been blogging during the two “bubble episodes” – would also have favoured tighter rather than easier monetary policy during these episodes.

So NGDP targeting is not a recipe for inflation, but rather an cure against bubbles. Therefore, NGDP targeting should be endorsed by anybody who favours sound money and nominal stability and despise monetary induced boom-bust cycles.

Ben maybe you should try “policy futures”?

My readers will know that I think that the Federal Reserve has taken a step in the right direction with its latest policy action. I do think that the fed finally after four years of failure is moving towards a more rule based monetary policy. However, it is certainly far from perfect and there is still a lot of risks involved.

The Minutes from the latest FOMC meeting was published yesterday and it is clear that the FOMC is well-aware that it needs to address it’s communication problem. That’s positive. However, it is also clear that the fed still don’t have a proper communication policy in place and even though we are moving towards a more rule based monetary policy it still not completely clear what the rule is and it is not entire clear how it should be implemented. We are still far away from Milton Friedman’s ideal of having a computer control monetary policy. However, I think that the fed should move in the direction of that ideal and it could start the journey toward this goal by introducing what we could call “policy futures”.

It is obvious that the fed is aware that there is problems with the present forecasting set-up within the fed. The key problem is one that every central bank in the world is facing – should the central bank forecast that it will fail? That is effectively what the fed has been doing so far when it is saying that it expect a fragile and weak recovery.

Scott Sumner has suggested that monetary policy should be “pegged” to a NGDP future, which would mean that the money base is increased or decreased continuously as market expectations for future level NGDP changes. This is basically the Friedman ideal of a computer – or rather the market – controlling monetary policy. However, a less radical plan where futures are “just” used for policy guidance and forecasting is also possible and that is what I suggest that the fed should look at.

There are some very clear advantages of using the market to forecast. First of all the fed would not have to know the “real model” of the US economy. Second the forecasts would be unbiased. Third the fed would have real-time forecasts of its policy variables.

It is pretty clear that the fed is now moving towards some kind of Evans rule where changes in the money base is a function of unemployment and inflation. We don’t know fed’s reaction function, but a version of the Evans rules could take the following form:

(1)    ∆b = α(U-U*)-β(π-πT)

Where ∆b is the change in the money base, α and β are coefficients, U is unemployment and U* is the fed’s unemployment target or the structural unemployment, π is inflation and πT is the inflation target.

There plenty of reasons to be skeptical about the fact that the fed is so clearly targeting real variables (employment/unemployment). However, by using policy futures it might be possible to greatly reduce these risks.

I imagine that the fed set up a futures or an options market on for example inflation, employment/unemployment and obviously NGDP on different time horizons.

Let’s say that the fed has the target of reducing unemployment to 6%, but also want to maintain long term price stability (keeping inflation around 2%). If structural unemployment is higher than 6% then that would obviously not be possible – and if the fed tried to push unemployment below 6% then inflation would explode. A policy future would greatly help assess this risk.

Hence, the fed could issue a put option that would be knocked in if unemployment dropped by 6% and inflation was below 2 or 3% at some future date – for example January 1 2013. Such an option would give an assessment about whether it is likely that the fed will hit it’s policy objectives. If the market assess that structural unemployment is above 6% then that would be reflected in the pricing of the put option.

If the fed issued a number of different policy futures and options on the key policy objectives it could get the markets’ assessment of whether it is on the right track in terms of fulfilling it’s monetary policy objectives or not by cross-checking the pricing of different policy futures.

Such policy futures could also greatly help the fed in it’s communication with the markets and it would probably also be much easier to get consensus on the FOMC about the possible risk to monetary policy.

The fed would very easily be able to set up such policy futures markets, but the informational gains would in my view be tremendous. The only “problem” would that the fed would need fewer economists to do forecasting…

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.

Woodford on NGDP targeting and Friedman

Michael Woodford’s Jackson Hole paper is a goldmine. I haven’t read all of it, but I just want to share this quote:

“Essentially, the nominal GDP target path represents a compromise between the aspiration to choose a target that would achieve an ideal equilibrium if correctly understood and the need to pick a target that can be widely understood and can be implemented in a way that allows for verification of the central bank’s pursuit of its alleged target, in the spirit of Milton Friedman’s celebrated proposal of a constant growth rate for a monetary aggregate. Indeed, it can be viewed as a modern version of Friedman’s “k-percent rule” proposal, in which the variable that Friedman actually cared about stabilizing (the growth rate of nominal income) replaces the monetary aggregate that he proposed as a better proximate target, on the ground that the Fed had much more direct control over the money supply. On the one hand, the Fed’s ability to directly control broad monetary aggregates (the ones more directly related to nominal income in the way that Friedman assumed) can no longer be taken for granted, under current conditions; and on the other hand, modern methods of forecast targeting make a commitment to the pursuit of a target defined in terms of variables that are not under the short-run control of the central bank more credible. Under these circumstances, a case can be made that a nominal GDP target path would remain true to Friedman’s fundamental concerns.”

Exactly! NGDP targeting is exactly in the spirit of Friedman.

And Woodford goes on to quote one of the founding fathers of Market Monetarism:

“See, for example, (David) Beckworth (2011) for an argument to this effect. Beckworth notes that Friedman (2003) praised the accuracy of “the Fed’s thermostat,” for having reduced M2 growth during the period of increasing “velocity” in 1988-1997, and then increased M2 growth by several percent- age points during a period of decreasing velocity in 1997-2003. One might conclude that Friedman valued successful stabilization of nominal GDP growth more than strict fidelity to a “k-percent rule.”

See David’s take on Woodford here and here is what Scott Sumner has to say.

Michael Woodford endorses NGDP level targeting

Here is from Bloomberg:

Central bankers should adopt a clear policy goal, such as the path for nominal gross domestic product, to make remaining easing options more effective under the limits of near-zero interest rates, according to Michael Woodford, a professor of political economy at Columbia University.

Such criteria would increase the impact of efforts to reset public expectations for interest rate policy, such as asset-purchases, Woodford said. Federal Reserve policy makers have kept the benchmark rate near zero since December 2008 and this month reiterated a plan to keep borrowing costs at record lows through at least late 2014.

“A more useful form of forward guidance, I believe, would be one that emphasizes the target criterion that will be used to determine when it is appropriate to raise the federal funds rate target above its current level, rather than estimates of the ‘lift-off’ date,” Woodford said in a paper presented today at the Fed’s annual symposium in Jackson Hole, Wyoming.

A pledge to restore nominal GDP “to the trend path it had been on up until the fall of 2008” would “make it clear that policy will have to remain looser in the near term” than indicated by the Taylor rule, he said. It would also “provide assurance that the unusually stimulative current policy stance does not imply any intention to tolerate continuing inflation above the Fed’s declared long-run inflation target.”

…

“But if a central bank’s intention in announcing such purchases is to send such a signal, the signal would seem more likely to have the desired effect if accompanied by explicit forward guidance, rather than regarded as a substitute for it,” Woodford said.

“A more logical policy would rely on a combination of commitment to a clear target criterion to guide future decisions about interest-rate policy with immediate policy actions that should stimulate spending immediately without relying too much on expectational channels,” Woodford said.

The Fed has carried out two rounds of bond purchases known as quantitative easing to reduce borrowing costs. In the first round starting in 2008, the Fed bought $1.25 trillion of mortgage-backed securities, $175 billion of federal agency debt and $300 billion of Treasuries. In the second round, announced in November 2010, the Fed bought $600 billion of Treasuries.

Policies that target specific credit areas, such as buying mortgage-backed securities, or the Bank of England’s Funding for Lending Scheme, may be more effective at boosting spending, though they are “more properly” viewed as fiscal as opposed to monetary stimulus, he said.

Combining central bankers’ nominal GDP target would also “increase the bang for the buck from fiscal stimulus” while limiting inflation concerns, Woodford said. “The most obvious recipe for success is one that requires coordination between the monetary and the fiscal authorities.”

Lets just say I agree with the policy recommendation – even though I certainly do not think US monetary policy is accommodative just because the fed funds rate is low.

Imagine if the ECB would host a conference where somebody would recommend NGDP level targeting…

Here is Woodford’s paper Methods of Policy Accommodation at the Interest-Rate Lower Bound

Update: My fellow Market Monetarists David Beckworth (who is quoted in Woodford’s paper) and Marcus Nunes also comment on Woodford.

The fiscal cliff and why fiscal conservatives should endorse NGDP targeting

One of the hottest political topics in the US today is the so-called fiscal cliff. The fiscal cliff is the expected significant fiscal tightening, which will kick in January 2013 when the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 expires – unless a deal is struck to postpone the tightening. The fiscal cliff is estimated to amount to 4% of GDP – hence a very substantial fiscal tightening.

So how much should we worry about the fiscal cliff? Keynesians claim that we should worry a lot. The Market Monetarist would one the other hand argue that the impact of the fiscal cliff will very much depend on the response of the Federal Reserve to the possible fiscal tightening. If the Fed completely ignores the impact of the fiscal cliff on aggregate demand – if there will be any – then it would be naive to argue that there would be no impact at all on aggregate demand – after all a 4% tightening of fiscal policy in one year is very substantial.

On the other hand if the Federal Reserve had an NGDP target then the impact would likely be minimal as the Fed “automatically” would fill any “hole” in aggregate demand created by the tightening of fiscal policy to keep nominal GDP on track. This of course is the Sumner critique – the fiscal multiplier will be zero under NGDP targeting or inflation targeting for that matter.

Note that I am not making any assumptions about the how the economy works. Even if we assume we are in a Keynesian world, where the “impulse” to aggregate demand from a fiscal tightening would be negative an NGDP targeting regime would ensure that the world would look like a “classical world” (fiscal policy will have no impact on aggregate demand). This by the way would also be the case under inflation targeting – which of course is closer to the actual policy the Fed is conducting.

Said in another we should expect that if fiscal policy indeed would be strongly negative for aggregate demand in the US and push inflation sharply down then the likelihood of more aggressive monetary easing from the Fed would increase and hence sharply reduce any negative effect on aggregate demand (note that nominal GDP is really just another word for aggregate demand – at least according to Market Monetarists like myself). Therefore, we should probably be significantly less worried than some Keynesians seem to be.

Furthermore, it is notable that the US stock market continues rise and inflation expectations have been inching up recently. This is not exactly an indication that the US is facing a sharp drop in aggregate demand in 2013. We can obviously not know why the markets seem so relatively relaxed about the fiscal cliff, but I would think that the reason is that the markets are pricing in a combination of a political compromise that significantly reduces the fiscal tightening in 2013 and also is pricing an increased likelihood of QE3 becoming a reality.

So the conclusion is that Keynesian fears about the scale of the shock to aggregate demand is somewhat overblown as a combination of the Sumner critique and political logrolling will probably reduce the negative shock. We, however, can’t be sure about that so wouldn’t it be great if we didn’t have to worry about this issue? NGDP level targeting could seriously reduce the worries about fiscal shocks.

Fiscal conservatives should endorse NGDP targeting

Both in the US and the euro zone calls for scaling back fiscal consolidation have been growing larger and politicians like the French President Hollande and from Keynesian economists like Paul Krugman and Brad DeLong have even demanded fiscal stimulus. To me it is pretty simple – the state of public finances in most euro zone countries and the US is horrible so I fundamentally don’t think that most countries can afford much fiscal stimulus. That said, I also think that the calls for austerity is somewhat hysterical and I find it rather unlikely that the markets would react very negative if the US budget deficit became 1-2 percentage points of GDP larger next year – just look at US treasury yields it is not so that the markets are telling us that the US economy is on the verge of bankruptcy. The markets are often wrong, but government default rarely happens out of the blue.

However, from a public choice perspective we should probably think that the deeper a country falls into recession the more likely it is that the wider public will vote for politicians like Hollande and policy makers are more and more likely to start listening to economists like Paul Krugman. That unfortunately will do very little to ending the crisis. Fiscal stimulus is not the answer to our problems – monetary easing is.

So fiscal conservatives are likely going to face more and more resistance – whether we like it or not. On the other hand if the central bank was operating a credible NGDP level target then fiscal conservatives could argue that negative impact of fiscal consolidation would be met by an easing of monetary policy to keep NGDP on track. Therefore there would be no reasons to worry about fiscal tightening hitting growth and increasing unemployment.

Even better imagine that the Federal Reserve tomorrow announced that it would do as much monetary easing needed to bring back NGDP to its pre-crisis trend by for example raising  NGDP by 15% from the present level by the end of 2013. Do you then think anybody would worry about a fiscal tightening of 4% of GDP? I think not.

Therefore, the conclusion is clear to me. Fiscal conservatives should endorse NGDP level targeting as it completely would undermine any Keynesian arguments for postponing fiscal consolidation. Furthermore, a commitment to keep NGDP on track would also likely make fiscal consolidation much less unpopular and therefore the likelihood of success would also increase.

Finally I would highlight two historical examples of successful fiscal consolidation. In the mid-1990s both the US and the UK undertook significant successful fiscal reforms that led to a significant improvement in the public finances. Both was undertaken while monetary conditions was eased significantly. As a result there was very little opposition to fiscal consolidation at the time and there was basically no negative impact on US and UK growth. In fact both economies grew robustly through out the fiscal consolidation phase. This of course is the opposite of the German experience from the early 1990s where the Bundesbank completely “neutralized” any stimulus from fiscal expansion in connection with the Germany reunification (See my earlier post on that topic here.)

PS Above I have not given any attention to the supply side effects of the “scheduled” tax hikes that follows as a result of the US fiscal cliff. NGDP level targeting would not deal with that problem and the issue should certainly not be ignored. Tax hikes can never increase the long-term growth potential of any economy, but the issue is not going to have any visible impact on real GDP growth in 2013 or 2014 for that matter. Supply side effects mostly work with long and variable lags. Furthermore, I am not arguing that one should ignore the fiscal cliff just because the Fed has the power to counteract it. After all the Fed’s performance in recent years has not exactly been impressive so a political compromise would probably be helpful for US growth in 2013 – at least it would reduce some risks of the US falling back into recession.

PPS this is my blog post #400 (including guest posts) since I started blogging last year.

Between the money supply and velocity – the euro zone vs the US

When crisis hit in 2008 it was mostly called the subprime crisis and it was normally assumed that the crisis had an US origin. I have always been skeptical about the US centric description of the crisis. As I see it the initial “impulse” to the crisis came from Europe rather than the US. However, the consequence of this impulse stemming from Europe led to a “passive” tightening of US monetary conditions as the Fed failed to meet the increased demand for dollars.

The collapse in both nominal (and real) GDP in the US and the euro zone in 2008-9 was very similar, but the “composition” of the shock was very different. In Europe the shock to NGDP came from a sharp drop in money supply growth, while the contraction in US NGDP was a result of a sharp contraction in money-velocity. The graphs below illustrate this.

The first graph is a graph with the broad money supply relative to the pre-crisis trend (2000-2007) in the euro zone and the US. The second graph is broad money velocity in the US and the euro zone relative to the pre-crisis trend (2000-2007).

The graphs very clearly illustrates that there has been a massive monetary contraction in the euro zone as a result of M3 significantly undershooting the pre-crisis trend. Had the ECB kept M3 growth on the pre-crisis trend then euro zone nominal GDP would long ago returned to the pre-crisis trend. On the other hand the Federal Reserve has actually been able to keep M2 on the pre-crisis path. However, that has not been enough to keep US NGDP on trend as M2-velocity has contracted sharply relative the pre-crisis trend.

Said in another way a M3 growth target of for example 6.5% would basically have been as good as an NGDP level target for the euro zone as velocity has returned to the pre-crisis trend. However, that would not have been the case in the US and that I my view illustrates why an NGDP level target is much preferable to a money supply target.

The European origin of the crisis – or how European banks caused a tightening of US monetary policy

Not surprisingly the focus of the discussion of the causes of the crisis often is on the US given both the subprime debacle and the collapse of Lehman Brothers. However, I believe that the shock actually (mostly) originated in Europe rather than the US. What happened in 2008 was that we saw a sharp rise in dollar demand coming from the European financial sector. This is best illustrated by the sharp drop in EUR/USD from close to 1.60 in July 2008 to 1.25 in early November 2008. The rise in dollar demand is obviously what caused the collapse in US money-velocity and in that regard it is notable that the rise in money demand in Europe primarily was an increase in demand for dollar rather than for euros.

This is why I stress the European origin of the crisis. However, the cause of the crisis nonetheless was a tightening of US monetary conditions as the Fed (initially) failed to appropriately respond to the increase in dollar demand – mostly because of the collapse of the US primary dealer system. Had the Fed had a more efficient system for open market operations in 2008 then I believe the crisis would have been much smaller and would have been over already in 2009. As the Fed got dollar-swap lines up and running and initiated quantitative easing the recovery got underway in 2009. This triggered a brisk recovery in both US and euro zone money-velocity. In that regard it is notable that the rebound in velocity actually was somewhat steeper in the euro zone than in the US.

The crisis might very well have ended in 2009, but new policy mistakes have prolonged the crisis and once again European problems are causing most headaches and the cause now clearly is that the ECB has allowed European monetary conditions to become excessively tight – just have a look at the money supply graph above. Euro zone M3 has now dropped more than 15% below the pre-crisis trend. This policy mistake has to some extent been counteracted by the Fed’s efforts to increase the US money supply, but the euro crisis have also led to another downleg in US money velocity. The Fed once again has failed to appropriately counteract this.

Both the Fed and the ECB have failed

In the discussion above I have tried to illustrate that we cannot fully understand the Great Recession without understanding the relationship between US and euro zone monetary policy and I believe that a full understanding of the crisis necessitates a discussion of European dollar demand.

Furthermore, the discussion shows that a credible money supply target would significantly have reduced the crisis in the euro zone. However, the shock to US money-velocity shows that an NGDP level target would “perform” much better than a simple money supply rule.

The conclusion is that both the Fed and the ECB have failed. The Fed failed to respond appropriately in 2008 to the increase in the dollar demand. On the other hand the ECB has nearly constantly since 2008/9 failed to increase the money supply and nominal GDP. Not to mention the numerous communication failures and the massively discretionary conduct of monetary policy.

Even though the challenges facing the Fed and ECB since 2008 have been somewhat different in nature I would argue that proper nominal targets (for example a NGDP level target or a price level target) and better operational procedures could have ended this crisis long ago.

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.
