Hjalmar Schacht’s echo – it all feels a lot more like 1932 than 1923

The weekend’s Greek elections brought a neo-nazi party (“Golden Dawn”) into the Greek parliament. The outcome of the Greek elections made me think about the German parliament elections in July 1932 which gave a stunning victory to Hitler’s nazi party. The Communist Party and other extreme leftist also did well in the Greek elections as they did in Germany in 1932. I am tempted to say that fascism is always and everywhere a monetary phenomenon. At least that was the case in Germany in 1932 as it is today in Greece. And as in 1932 central bankers does not seem to realise the connection between monetary strangulation and the rise of extremist political forces.

The rise of Hitler in 1932 was to a large extent a result of the deflationary policies of the German Reichbank under the leadership of the notorious Hjalmar Schacht who later served in Hitler’s government as Economics Ministers.

Schacht was both a hero and a villain. He successfully ended the 1923 German hyperinflation, but he also was a staunch supporter of the gold standard which lead to massive German deflation that laid the foundation for Hitler’s rise to power. After Hitler’s rise to power Schacht helped implement draconian policies, which effectively turned Germany into a planned economy that lead to the suffering of millions of Germans and he was instrumental in bringing in policies to support Hitler’s rearmament policies. However, he also played a (minor) role in the German resistance movement to Hitler.

The good and bad legacy of Hjalmar Schacht is a reminder that central bankers can do good and bad, but also that central bankers very seldom will admit when they make mistakes. This is what Matthew Yglesias in a blog post from last year called the Perverse Reputational Incentives In Central Banking.

Here is Matt:

I was reading recently in Hjalmar Schacht’s biography Confessions of the Old Wizard … and part of what’s so incredible about it are that Schacht’s two great achievements—the Weimar-era whipping of hyperinflation and the Nazi-era whipping of deflation—were both so easy. The both involved, in essence, simply deciding that the central bank actually wanted to solve the problem.

To step back to the hyperinflation. You might ask yourself how things could possibly have gotten that bad. And the answer really just comes down to refusal to admit that a mistake had been made. To halt the inflation, the Reichsbank would have to stop printing money. But once the inflation had gotten too high for Reichsbank President Rudolf Havenstein to stop printing money and stop the inflation would be an implicit admission that the whole thing had been his fault in the first place and he should have done it earlier…

…So things continued for several years until a new government brought Schacht on as a sort of currency czar. Schacht stopped the private issuance of money, launched a new land-backed currency and simply . . . refused to print too much of it. The problem was solved both very quickly and very easily…

…The institutional and psychological problem here turns out to be really severe. If the Federal Reserve Open Market Committee were to take strong action at its next meeting and put the United States on a path to rapid catch-up growth, all that would do is serve to vindicate the position of the Fed’s critics that it’s been screwing up for years now. Rather than looking like geniuses for solving the problem, they would look like idiots for having let it fester so long. By contrast, if you were to appoint an entirely new team then their reputational incentives would point in the direction of fixing the problem as soon as possible.

Matt is of course very right. Central banks and central banks alone determines inflation, deflation, the price level and nominal GDP. Therefore central banks are responsible if we get hyperinflation, debt-deflation or a massive drop in nominal GDP. However, central bankers seem to think that they are only in control of these factors when they are “on track”, but once the nominal variables move “off track” then it is the mistake of speculators, labour unions or irresponsible politicians. Just think of how Fed chief Arthur Burns kept demanding wage and price controls in the early 1970s to curb inflationary pressures he created himself by excessive money issuance.  The credo seems to be that central bankers are never to blame.

Here is today’s German central bank governor Jens Weidmann in comment in today’s edition of the Financial Times:

Contrary to widespread belief, monetary policy is not a panacea and central banks’ firepower is not unlimited, especially not in the monetary union. First, to protect their independence central banks in the eurozone face clear constraints to the risks they are allowed to take.

…Second, unconditional further easing would ignore the lessons learned from the financial crisis.

This crisis is exceptional in scale and scope and extraordinary times do call for extraordinary measures. But we have to make sure that by putting out the fire now, we are not unwittingly preparing the ground for the next one. The medicine of a near-zero interest rate policy combined with large-scale intervention in financial markets does not come without side effects – which are all the more severe, the longer the drug is administered.

I don’t feel like commenting more on Weidmann’s comments (you can pretty well guess what I think…), but I do note that German long-term bond yields today have inch down further and is now at record low levels. Normally long-term bond yields and NGDP growth tend to move more or less in sync – so with German government 10-year bond yields at 1.5% we can safely say that the markets are not exactly afraid of inflation. Or said in another way, if ECB deliver 2% inflation in line with its inflation target over the coming decade then you will be loosing 1/2% every year by holding German government bonds. This is not exactly an indication that we are about to repeat the mistakes of the Reichbank in 1923, but rather an indication that we are in the process of repeating the mistakes of 1932. The Greek election is sad testimony to that.

PS David Glasner comments also comments on Jens Weidmann. He is not holding back…

PPS Scott Sumner today compares the newly elected French president Francois Hollande with Léon Blum. I have been having been thinking the same thing. Léon Blum served as French Prime Minister from June 1936 to June 1937. Blum of course gave up the gold standard in 1936 and allowed a 25% devaluation of the French franc. While most of Blum’s economic policies were grossly misguided the devaluation of the franc nonetheless did the job – the French economy started a gradual recovery. Unfortunately at that time the gold standard had already destroyed Europe’s economy and the next thing that followed was World War II. I wonder if central bankers ever study history…They might want to start with Adam Tooze’s Wages of Destruction.

Update: See Matt O’Brien’s story on “Europe’s FDR? How France’s New President Could Save Europe”. Matt is making the same point as me – just a lot more forcefully.

Exchange rates are not truly floating when we target inflation

There is a couple of topics that have been on my mind lately and they have made me want to write this post. In the post I will claim that inflation targeting is a soft-version of what economists have called the fear-of-floating. But before getting to that let me run through the topics on my mind.

1) Last week I did a presentation for a group of Norwegian investors and even thought the topic was the Central and Eastern European economies the topic of Norwegian monetary politics came up. I am no big expert on the Norwegian economy or Norwegian monetary policy so I ran for the door or rather I started to talk about an other large oil producing economy, which I know much better – The Russian economy. I essentially re-told what I recently wrote about in a blog post on the Russian central bank causing the 2008/9-crisis in the Russian economy, by not allowing the ruble to drop in line with oil prices in the autumn of 2008. I told the Norwegian investors that the Russian central bank was suffering from a fear-of-floating. That rang a bell with the Norwegian investors – and they claimed – and rightly so I think – that the Norwegian central bank (Norges Bank) also suffers from a fear-of-floating. They had an excellent point: The Norwegian economy is booming, domestic demand continues to growth very strongly despite weak global growth, asset prices – particularly property prices – are rising strongly and unemployment is very low and finally do I need to mention that Norwegian NGDP long ago have returned to the pre-crisis trend? So all in all if anything the Norwegian economy probably needs tighter monetary policy rather than easier monetary policy. However, this is not what Norges Bank is discussing. If anything the Norges Bank has recently been moving towards monetary easing. In fact in March Norges Bank surprised investors by cutting interest rates and directly cited the strength of the Norwegian krone as a reason for the rate cut.

2) My recent interest in Jeff Frankel’s idea that commodity exporters should peg their currency to the price of the main export (PEP) has made me think about the connect between floating exchange rates and what monetary target the central bank operates. Frankel in one of his papers shows that historically there has been a rather high positive correlation between higher import prices and monetary tightening (currency appreciation) in countries with floating exchange rates and inflation targeting. The mechanism is clear – strict inflation targeting central banks an increase in import prices will cause headline inflation to increase as the aggregate supply curve shots to the left and as the central bank does not differentiate between supply shocks and nominal shocks it will react to a negative supply shock by tightening monetary policy causing the currency to strengthen. Any Market Monetarist would of course tell you that central banks should not react to supply shocks and should allow higher import prices to feed through to higher inflation – this is basically George Selgin’s productivity norm. Very few central banks allow this to happen – just remember the ECB’s two ill-fated rate hikes in 2011, which primarily was a response to higher import prices. Sad, but true.

3) Scott Sumner tells us that monetary policy works with long and variable leads. Expectations are tremendously important for the monetary transmission mechanism. One of the main channels by which monetary policy works in a small-open economy  – with long and variable leads – is the exchange rate channel. Taking the point 2 into consideration any investor would expect the ECB to tighten monetary policy  in responds to a negative supply shock in the form of a increase in import prices. Therefore, we would get an automatic strengthening of the euro if for example oil prices rose. The more credible an inflation target’er the central bank is the stronger the strengthening of the currency. On the other hand if the central bank is not targeting inflation, but instead export prices as Frankel is suggesting or the NGDP level then the currency would not “automatically” tend to strengthen in responds to higher oil prices. Hence, the correlation between the currency and import prices strictly depends on what monetary policy rule is in place.

These three point leads me to the conclusion that inflation targeting really just is a stealth version of the fear-of-floating. So why is that? Well, normally we would talk about the fear-of-floating when the central bank acts and cut rates in responds to the currency strengthening (at a point in time when the state of the economy does not warrant a rate cut). However, in a world of forward-looking investors the currency tends move as-if we had the old-fashioned form of fear-of-floating – it might be that higher oil prices leads to a strengthening of the Norwegian krone, but expectations of interest rate cuts will curb the strengthen of NOK. Similarly the euro is likely to be stronger than it otherwise would have been when oil prices rise as the ECB again and again has demonstrated the it reacts to negative supply shocks with monetary easing.

Exchange rates are not truly floating when we target inflation 

And this lead me to my conclusion. We cannot fundamentally say that currencies are truly floating as long as central banks continue to react to higher import prices due to inflation targeting mandates. We might formally have laid behind us the days of managed exchange rates (at least in North America and Europe), but de facto we have reintroduced it with inflation targeting. As a consequence monetary policy becomes excessively easy (tight) when import prices are dropping (increasing) and this is the recipe for boom-bust. Therefore, floating exchange rates and inflation targeting is not that happy a couple it often is made out to be and we can fundamentally only talk about truly floating exchange rates when monetary policy cease to react to supply shocks.

Therefore, the best way to ensure true exchange rates flexibility is through NGDP level targeting and if we want to manage exchange rates then at least do it by targeting the export price rather than the import price.

Forget about those black swans

It has become highly fashionable to talk about “black swans” since the crisis began in 2008 and now even Scott Sumner talks about it in his recent post “Don’t forget about those black swans”. Ok, Scott is actually not obsessed with black swans, but his headline reminded me how much focus there is on “black swans” these days – especially among central bankers and regulators and to some extent also among market participants.

What is a black swan? The black swan theory was popularized by Nassim Taleb in 2007 book “The Black Swan”. Taleb’s idea basically is that the financial markets underprice the risk of extreme events happening. Taleb obviously felt vindicated when crisis hit in 2008. The extreme event happened and it had clearly not been priced by the market in advance.

Lets go back to back to Scott’s post. Here he quotes Matt Yglesias:

Here’s a fun Intrade price anomaly that showed up this morning. The markets indicate that there’s more than a 3 percent chance that neither Barack Obama nor Mitt Romney will win the presidential election. That’s clearly way too high.

Scott then counter Matt by saying that we should not forget “something unusual happening”:

1.  One of the two major candidates is assassinated, and the replacement is elected (as in Mexico’s 1994 election.)

2.  Ditto, except one pulls out due to health problems, or scandal.

3.  A third party candidate comes out of nowhere to get elected.

Scott is of course right. All this could happen and as a consequence it would obviously be wrong if the market had price a 100% chance that nobody else than Obama or Romney would become US president.

Scott and I tend to think that financial markets are (more or less) efficient and as a consequence we would not be gambling men. Scott nonetheless seem to think that the odds are good:

“But 3% is low odds.  It’s basically saying once in ever 130 years you’d expect something really weird to happen in US presidential politics during an election year.   That’s a long time!  Given all the weird things that have happened, how unlikely is it?  Some might counter that none of the three scenarios I’ve outlined have occurred in the US during an election year (my history is weak so I’m not certain.)  But mind-bogglingly unusual things have happened on occasion.  On November 10, 1972, what kind of odds would Intrade have given on neither Nixon nor Agnew being President on January 1 1975?”

Scott certainly have a good point, but I will not question the market on this one. The market pricing is the best assessment of risk we have. If not there would be money in street ready to pick up for anybody – and there is not. Obviously Taleb disagrees as he believe that markets tend to underprice risk. However, I fundamentally think that Taleb is wrong and I don’t see much evidence that market underprice black swan events. The fact that rare events happen is not evidence that the market on average underprice the likelihood of this events.

The fashion long-shot bias and central banks

In the evidence from betting markets seem to indicate that if anything bettors tend to have a favourite-longshot bias meaning that they tend to overprice the likelihood that the favourite will loose elections or sport games. Said in another way if anything bettors tend to overprice the likelihood of a black swan events. I happen to think that this is not a market problem in markets in general, but it nonetheless indicates that if anything the problem is too much focus on black swan events rather than too little focus on them.

This to a very large extent has been the case of the past 4 years – especially in regard to central banking and banking regulation. There seem to be a near-obsession among some policy makers that a new black swan could turn up. How often have we heard the talk about the major risk of bubbles if interest rates are kept too low too long and most of the new financial regulation being push through across the world these days is justified by reference to the risk of some kind of black swan event.

Media and policy makers in my view have become obsessed with extreme events happening – you will be reminded about that every time you go through the security check in any airport in the world.

The obsession with black swan events is highly problematic as the cost of policy makers obsessing about very unlikely events happening lead them to implement very costly regulation that lead to massive waste of resources. Again just think about how many hours you have spend waiting to get through airport security over the last couple of years and if you think that is bad just think of the cost resulting from excessive new regulation of the global financial markets. So my suggestion is clearly to forget about those black swans!

Finally three book recommendations:

Risk by Dan Gardner that tells about the “politics of fear” (of black swans).

The Myth of the Rational Voter by Bryan Caplan explains why democracy tend to lead to irrationality while market lead to rationality. Said in another way policy makers would be more prone to focus on black swans than market participants in free markets would be.

Risk, Uncertain and Profit – Frank Knight’s classic. If you are really interested in the issues of risk and uncertainty then there is no reason at all to read Taleb’s books (I have read both The Black Swan and Fooled by Randomness – they are “fun” and something you can read while you are waitin in line at the security check in the airport, but it is certainly not Nobel prize material). Instead just read Knight’s classic. It is much more insightful. It is actually something that frustrates me a great deal about Taleb’s books – there is really nothing new in what he is saying, but he claims to have come up with everything himself.

David Beckworth on Bernanke’s inconsistencies

David Beckworth has an extremely insightful blog post on the inconsistencies of Ben Bernanke’s views as an academic and as a central bank chief.

Anybody who have read the academic Ben Bernanke’s analysis of the Great Depression and particularly of Japan’s 1990s deflation will be stroke by how different his views are from Fed chairman Bernanke’s views. Bernanke obviously claims that he is not inconsistent. Furthermore, Bernanke claims that the situation in the US is very different from Japan in the 1990s. David on the other very clearly shows that Bernanke is indeed inconsistent and that the academic Bernanke would have realized that there are significant similarities between Japan in the 1990s and the US today.

David’s graph on Japanese and US demand deficiency shows it all. Have a look here.

I really have not much to add other than I think David is 100% right. The Federal Reserve is risking repeating the failures of the Bank of Japan if the Fed chairman keeps forgetting about the excellent research on Japan by the academic Ben Bernanke.

Scott Sumner has two post on Bernanke – here and here. Marcus Nunes also has a comment on Bernanke’s inconsistencies.

PS This discussion reminded me of one of my own earlier posts: Needed: Rooseveltian Resolve. The story is the same – I miss Ben Bernanke the academic.

Political news kept slipping into the financial section – European style

European news over the weekend:

Françcois Hollande won the first round of voting ahead for incumbent president Sarkozy. However, nationalist candidate and leader of Front National (FN) Marine Le Pen got 18%. That is the highest support for a FN presidential candidate ever.

The Dutch government de facto collapsed after Geert Wilders’ populist Freedom Party refused to back anymore austerity measures.

 At the core of these two events obviously is the ongoing European crisis.

The response from European central bankers (all from the last couple of days):

ECB chief Mario Draghi in response to calls for European monetary easing from the IMF said: “None of the advice that the IMF is offering has been discussed by the Governing Council, in recent times at least”

Luc Coene, ECB Governing Council member and governor of Belgium’s central bank: “We have done what we can do so far within our mandate and within the possibilities we have”

Bundesbank president Jens Weimann: “the problems in Europe can’t be solved by monetary policy measures.”

Weidmann continues: “Higher interest rates are also a spur toward reforms” (Weidman is referring to bond yields in countries like Spain)

I feel like quoting Scott Sumner:

I once read all the New York Times from the 1930s (on microfilm.)  You can’t even imagine how frustrating it was.  They knew they had a big problem.  Then knew that deflation had badly hurt the economy (including the capitalists.)  They knew that monetary policy could reflate.  And yet . . .

Weeks went by, then months, then years.  Somehow they never connected the dots.

“Monetary policy is already highly stimulative.”

“There’s a danger we’d overshoot toward too much inflation.”

“Maybe the problems are structural.”

“There are green shoots, things are getting worse at a slower pace.  The economy needs to heal itself.”

“Consumer demand is saturated.  Even workingmen can now afford iceboxes and automobiles.  We produced too much stuff in the 1920s.”

And the worst part was the way political news kept slipping into the financial section.  Nazis make ominous gains in the 1932 German elections, Spanish Civil War, etc, etc.  In the 1930s the readers didn’t know what came next—but I did. 

Thankfully we can learn from their mistakes.

Thanks Scott. I don’t feel I need to add anything…Very depressing indeed.

Lets concentrate on the policy framework

Here is Scott Sumner:

I’ve noticed that when I discuss economic policy with other free market types, it’s easier to get agreement on broad policy rules than day-to-day discretionary decisions.

I have noticed the same thing – or rather I find that when pro-market economists are presented with Market Monetarist ideas based on the fact that we want to limit the discretionary powers of central banks then it is much easier to sell our views than when we just argue for monetary “stimulus”. I don’t want central bank to ease monetary policy. I don’t want central banks to tighten monetary policy. I simply want to central banks to stop distorting relative prices. I believe the best way to ensure that is with futures based NGDP targeting as this is the closest we get to the outcome that would prevail under a truly free monetary system with competitive issuance of money.

I have often argued that NGDP level targeting is not about monetary stimulus (See here, here and here) and argued that NGDP level targeting is the truly free market alternative (see here).

This in my view is the uniting view for free market oriented economists. We can disagree about whether monetary policy was too loose in the US and Europe prior to 2008 or whether it became too tight in 2008/9. My personal view is that both US and European monetary policy likely was (a bit!) too loose prior to 2008, but then turned extremely tight in 2008/09. The Great Depression was not caused by too easy monetary policy, but too tight monetary policy. However, in terms of policy recommendations is that really important? Yes it is important in the sense of what we think that the Fed or the ECB should do right now in the absence of a clear framework of NGDP targeting (or any other clear nominal target). However, the really important thing is not whether the Fed or the ECB will ease a little bit more or a little less in the coming month or quarter, but how we ensure the right institutional framework to avoid a future repeat of the catastrophic policy response in 2008/9 (and 2011!). In fact I would be more than happy if we could convince the ECB and the Fed to implement NGDP level target at the present levels of NGDP in Europe and the US – that would mean a lot more to me than a little bit more easing from the major central banks of the world (even though I continue to think that would be highly desirable as well).

What can Scott Sumner, George Selgin, Pete Boettke, Steve Horwitz, Bob Murphy and John Taylor all agree about? They want to limit the discretionary powers of central banks. Some of them would like to get rid of central banks all together, but as long as that option is not on the table they they all want to tie the hands of central bankers as much as possible. Scott, Steve and George all would agree that a form of nominal income targeting would be the best rule. Taylor might be convinced about that I think if it was completely rule based (at least if he listens to Evan Koeing). Bob of course want something completely else, but I think that even he would agree that a futures based NGDP targeting regime would be preferable to the present discretionary policies.

So maybe it is about time that we take this step by step and instead of screaming for monetary stimulus in the US and Europe start build alliances with those economists who really should endorse Market Monetarist ideas in the first place.

Here are the steps – or rather the questions Market Monetarists should ask other free market types (as Scott calls them…):

1) Do you agree that in the absence of Free Banking that monetary policy should be rule based rather than based on discretion?

2) Do you agree that markets send useful and appropriate signals for the conduct of monetary policy?

3) Do you agree that the market should be used to do forecasting for central banks and to markets should be used to implement policies rather than to leave it to technocrats? For example through the use of prediction markets and futures markets. (See my comments on prediction markets and market based monetary policy here and here).

4) Do you agree that there is good and bad inflation and good and bad deflation?

5) Do you agree that central banks should not respond to non-monetary shocks to the price level?

6) Do you agree that monetary policy can not solve all problems? (This Market Monetarists do not think so – see here)

7) Do you agree that the appropriate target for a central bank should be to the NGDP level?

I am pretty sure that most free market oriented monetary economists would answer “yes” to most of these questions. I would of course answer “yes” to them all.

So I suggest to my fellow Market Monetarists that these are the questions we should ask other free market economists instead of telling them that they are wrong about being against QE3 from the Fed. In fact would it really be strategically correct to argue for QE3 in the US right now? I am not sure. I would rather argue for strict NGDP level targeting and then I am pretty sure that the Chuck Norris effect and the market would do most of the lifting. We should basically stop arguing in favour of or against any discretionary policies.

PS I remain totally convinced that when economists in future discuss the causes of the Great Recession then the consensus among monetary historians will be that the Hetzelian-Sumnerian explanation of the crisis was correct. Bob Hetzel and Scott Sumner are the Hawtreys and Cassels of the day.

The missing equation

Scott Sumner has written dozens of blog posts trying to explain to why the fiscal multiplier is zero if the central bank targets the NGDP level, the price level or inflation. Said in another way Scott – as do I – strongly believe that the impact of fiscal policy strongly dependent the monetary policy reaction to fiscal tightening or fiscal easing (Even today Scott has a discussion of the fiscal multiplier). In fact I don’t even think it is meaningful to talk about fiscal policy as something that can “stimulate” demand. Hence, in a pure barter economy we cannot imagine fiscal policy having any impact on demand as demand always will equal supply in a barter economy. The famous Say’s Law holds in a barter economy and as such there would be full crowding out of fiscal policy. Hence, fiscal policy will only have an impact on demand if monetary policy “plays along”.

Our view is however far from the consensus among economists. Rather most economists think that you can use fiscal policy to “manage” nominal spending/demand. Even economists who in general do not find activist fiscal policy desirable tend to think that fiscal policy can impact nominal demand.

Today after working on some macroeconomic models myself I finally realised that the problem is that the “models” that most economists have in their heads are missing an equation (or at least one equation). Hence, most economists – and here I am talking about practicing macroeconomists like central bank economists or financial sector economists like myself – tend to give very little or no attention at all to the monetary policy regime of the economy they are analysing.

Therefore, the missing equation in most “models” is the policy reaction function of the central bank. And it might even be worse as it seem like most practical macroeconomists tend to assume that the central bank “accommodates” any change in fiscal policy so when fiscal policy is eased the central bank plays along and just automatically increase the money supply so to increase nominal GDP (with sticky prices that will increase RGDP and reduce unemployment). In such a world the “fiscal” multiplier obviously is positive. The problem is, however, that it is not really fiscal policy as such which is increasing NGDP, but the central bank’s “automatic” easing of monetary policy.

This assumption clearly is counterfactual. Anybody who has watched the actions of for example the ECB over the last couple of years would know that central banks certainly does not automatically play along.

The fact that many economists do not realise that they are missing an equation in their (mental) models also means that they completely fail to realise that the causality in their models are hugely dependent on the monetary policy reaction function. This is also why it is so hard for many to comprehend that monetary policy can work with long and variable leads (See my discussion of monetary policy leads and lags here – the discussion is basically a variation of the discussion in this post).

If you don’t believe me then try to have a look at the regular macroeconomic reports of central banks around world. In most of these reports the story of causality is pretty much a simple national account model, where increases in private consumption, investment and government spending etc. are described as “automatically” leading to an increase in real and nominal GDP. The monetary policy reaction is given little or no attention.

This description is of course not totally fair as many central banks are using so-called DSGE models that take explicitly take into account (some kind of) the monetary policy reaction. However, one thing is a model for simulations – another thing is the verbal description of the economy.

See for example here:

“The slowing domestic demand growth observed since 2010 Q4 turned into a noticeable annual decline in 2011 Q3. This decline was due to all its components, but most of all to change in inventories…Household and government consumption, whose annual decline intensified, affected domestic demand to a lesser extent. A renewed decline in fixed investment also contributed to the contraction in domestic demand.”

This is from the Czech central bank’s latest quarterly inflation report (page 35). We are told that demand slowed because of weak private consumption and tighter fiscal policy have lowered demand growth. However, what role did monetary policy play in this? Isn’t nominal demand sorely determined by monetary policy? So we cannot see the slowing of Czech demand without taking into account monetary policy.

In fact it is interesting that when central bankers describe the ups and downs in the economy nearly never hold themselves accountable. If inflation overshoots the inflation target we rarely (in fact never) hear central banks say “the failure to fulfil our inflation target was due to our overly loose monetary policy”. I wouldn’t really expect that and frankly I also hate admitting being mistaken. But this is nonetheless telling of the general tendency for macroeconomists – including those working for central banks – to fail to realise the importance of the monetary policy reaction function.

I should of course stress that I am certainly no saint. I am as lazy as any other economist and I most admit to many times both in written and spoken form to have argued along the lines of the “national account model”, but I hope that I at least know when I am intellectually lazy.

PS The mentioning of the Czech central bank’s inflation report above is not meant as a specific critique of my friends at the CNB. The economists at the CNB are certainly capable economists and it should be noted that the DSGE model used by the CNB’s research department explicitly tries to take into account the monetary policy reaction function of the board of the CNB.

Long and variable leads and lags

Scott Sumner yesterday posted a excellent overview of some key Market Monetarist positions. I initially thought I would also write a comment on what I think is the main positions of Market Monetarism but then realised that I already done that in my Working Paper on Market Monetarism from last year – “Market  Monetarism – The  Second  Monetarist  Counter-­revolution”. 

My fundamental view is that I personally do not mind being called an monetarist rather than a Market Monetarist even though I certainly think that Market Monetarism have some qualities that we do not find in traditional monetarism, but I fundamentally think Market Monetarism is a modern restatement of Monetarism rather than something fundamentally new.

I think the most important development in Market Monetarism is exactly that we as Market Monetarists stress the importance of expectations and how expectations of monetary policy can be read directly from market pricing. At the core of traditional monetarism is the assumption of adaptive expectations. However, today all economists acknowledge that economic agents (at least to some extent) are forward-looking and personally I have no problem in expressing that in the form of rational expectations – a view that Scott agrees with as do New Keynesians. However, unlike New Keynesian we stress that we can read these expectations directly from financial market pricing – stock prices, bond yields, commodity prices and exchange rates. Hence, by looking at changes in market pricing we can see whether monetary policy is becoming tighter or looser. This also has to do with our more nuanced view of the monetary transmission mechanism than is found among mainstream economists – including New Keynesians. As Scott express it:

Like monetarists, we assume many different transmission channels, not just interest rates.  Money affects all sorts of asset prices.  One slight difference from traditional monetarism is that we put more weight on the expected future level of NGDP, and hence the expected future hot potato effect.  Higher expected future NGDP tends to increase current AD, and current NGDP.

This is basically also the reason why Scott has stressed that monetary policy works with long and variable leads rather than with long and variable lags as traditionally expressed by Milton Friedman. In my view there is however really no conflict between the two positions and both are possible dependent on the institutional set-up in a given country at a given time.

Imagine the typical monetary policy set-up during the 1960s or 1970s when Friedman was doing research on monetary matters. During this period monetary policy clearly was missing a nominal anchor. Hence, there was no nominal target for monetary policy. Monetary policy was highly discretionary. In this environment it was very hard for market participants to forecast what policies to expect from for example the Federal Reserve. In fact in the 1960s and 1970s the Fed would not even bother to announce to market participant that it had changed monetary policy – it would simply just change the policy – for example interest rates. Furthermore, as the Fed was basically not communicating directly with the markets market participant would have to guess why a certain policy change had been implemented. As a result in such an institutional set-up market participants basically by default would have backward-looking expectations and would only gradually learn about what the Fed was trying to achieve. In such a set-up monetary policy nearly by definition would work with long and variable lags.

Contrary to this is the kind of set-up we had during the Great Moderation. Even though the Federal Reserve had not clearly formulated its policy target (it still hasn’t) market participants had a pretty good idea that the Fed probably was targeting the nominal GDP level or followed a kind of Taylor rule and market participants rarely got surprised by policy changes. Hence, market participants could reasonably deduct from economic and financial developments how policy would be change in the future. During this period monetary policy basically became endogenous. If NGDP was above trend then market participant would expect that monetary policy would be tightened. That would increase money demand and push down money-velocity and push up short-term interest rates. Often the Fed would even hint in what direction monetary policy was headed which would move stock prices, commodity prices, the exchange rates and bond yields in advance for any actual policy change. A good example of this dynamics is what we saw during early 2001. As a market participant I remember that the US stock market would rally on days when weak US macroeconomic data were released as market participants priced in future monetary easing. Hence, during this period monetary policy clear worked with long and variable leads.

In fact if we lived in a world of perfectly credible NGDP level targeting monetary policy would be fully automatic and probably monetary easing and tightening would happen through changes in money demand rather than through changes in the money base. In such a world the lead in monetary policy would be extremely short. This is the Market Monetarist dream world. In fact we could say that not only is “long and variable leads” a description of how the world is, but a normative position of how it should be.

Concluding there is no conflict between whether monetary policy works with long and variable leads or lags, but rather this is strictly dependent on the monetary policy regime and how monetary policy is implemented. A key problem in both the ECB’s and the Fed’s present policies today is that both central banks are far from clear about what nominal targets they have and how to achieve it – in some ways we are back to the pre-Great Moderation days of policy uncertainty. As a consequence market participants will only gradually learn about what the central bank’s real policy objectives are and therefore there is clearly an element of long and variable lags in monetary policy. However, if the Fed tomorrow announced that it would aim to increase NGDP by 15% by the end of 2013 and it would try to achieve that by buying unlimited amounts of foreign currency I am pretty sure we would swiftly move to a world of instantaneously working monetary policy – hence we would move from a quasi-Friedmanian world to a Sumnerian world.

Without rules we live in Friedmanian world – with clear nominal targets we live live in Sumnerian world.

PS Today is a Sumnerian day – hints from both the Fed and the ECB about possible monetary tightening is leading to monetary policy tightening today. Just take a look at US stock markets…(Ok, Greek worries is also playing apart, but that is passive monetary tightening as dollar demand increases)

NGDP level targeting and the Fed’s mandate

Renee Haltom has an interesting article in the recent edition of Richmond’s Fed’s magazine Region Focus on “Would a LITTLE inflation produce a BIGGER recover?”.

Renee among other things discusses NGDP targeting – it is unclear from the article whether it is a reference to growth or level targeting and somewhat surprisingly Market Monetarists such as Scott Sumner is not mentioned in the discussion. Rather Renee Haltom has interviewed Bennett McCallum. Professor McCallum is of course the grandfather of Market Monetarism so Renee is forgiven for not mentioning Scott.

What I found most interesting in Renee’s discussion was actually the relationship between NGDP targeting and the Fed’s legal mandate:

“NGDP is everything that is produced times the current prices people pay for it. It is similar to “real” GDP, the measure of economic growth reported in the news, except NGDP isn’t adjusted for inflation. One appeal is that growth in NGDP is the sum of exactly two things: inflation and the growth rate of real GDP (the amount of actual goods and services produced). Thus, it captures both sides of the Fed’s mandate in a single variable.”

So what Renee is basically suggesting is a that NGDP targeting would be fully comparable with the Federal Reserve’s mandate – to ensure price stability as well as to maximize employment. Unlike Scott Sumner I don’t think the Fed’s mandate is meaningful. The Fed should not try to maximize employment. In the long run employment is determined by factors completely outside of the Fed’s control. In the long run unemployment is determined by supply factors. In my view the only task of the Fed should be to ensure nominal stability and monetary neutrality (not distort relative prices) and the best way to do that is through a NGDP level target. However, lets play along and say that the Fed’s mandate is meaningful.

In his 2001 paper “U.S. Monetary Policy During the 1990s” Greg Mankiw suggested that Fed’s policy reaction function (for interest rates) could be seen as a function of the rate of unemployment minus core inflation. Lets call this measure Mankiw’s constant. The clever reader will of course notice that we now capture Fed’s mandate in one variable.

The graph below shows Mankiw’s constant and the ‘NGDP gap’ defined as percentage deviation from the trend in nominal GDP from 1990 to 2007 (the Great Moderation period).

The graph is pretty clear – there is a very strong correlation between the Fed’s mandate and NGDP level targeting. If the Fed keeps NGDP on trend then it will also ensure that Mankiw constant in fact would be a constant and fulfill it’s mandate. The graph of course also shows very clearly that the Federal Reserve at the moment is very far from fulfilling its mandate.

Given the very strong correlation between Mankiw’s constant and the NGDP gap it should be pretty easy for the Fed to argue that NGDP level (!) targeting is fully comparable with the Fed’s target. So Ben why are you still waiting?

Most people do “national accounting economics” – including most Austrians

Yesterday, I did a presentation about  monetary explanations for the Great Depression (See my paper here) at a conference hosted by the Danish Libertas Society. The theme of the conference was Austrian economics so we got of to an interesting start when I started my presentation with a bashing of Austrian business cycle theory – particularly the Rothbardian version (you know that has given me a headache recently).

The debate at the conference reminded me that most people – economists and non-economists – have a rather simple keynesian model in their heads or rather a simple national account model in their head.

We all the know the basic national account identity:

(1) Y=C+I+G+X-M

It is notable that most people are not clear about whether Y is nominal or real GDP. In the standard keynesian textbook model it is of course not important as prices (P) are assumed to be fixed and equal to one.

The fact that most people see the macroeconomics in this rather standard keynesian formulation means that they fail to understand the nominal character of recessions and hence nearly by construction they are unable to comprehend that the present crisis is a result of monetary policy mistake.

Whether austrian, keynesian or lay-person the assumption is that something happened on the righthand side of (1) and that caused Y to drop. The Austrians claim that we had an unsustainable boom in investments (I) caused by too low interest rates and that that boom ended in a unavoidable drop I. The keynesians (of the more traditional style) on the other hand claim that private consumption (C) and investments (I) is driven by animal spirits –  both in the boom and the bust.

What both keynesians and austrians completely fail to realise is the importance of money. The starting point of macroeconomic analysis should not be (1), but rather the equation of exchange:

(2) MV=PY

I have earlier argued that when we teach economics we should start out we money-free and friction-free micro economy. Then we should add money, move to aggregated prices and quantities and price rigidities. That is what we call macroeconomics.

If we can make people understand that the starting point of macroeconomic analysis should be (2) and not (1) then we can also convince them that the present recession (as all other recessions) is caused by a monetary contraction rather than drop in C or I. The drop in C and I are consequences rather the reasons for the recessions.

In this regard it is also important to note that Austrian Business Cycle Theory as formulated by Hayek or Rothbard basically is keynesian in nature in the sense that it is not really monetary theory. The starting point is that interest rates impact the capital structure and investments and that impacts Y – first as a boom and then as a bust. This is also why it is hard to convince Austrians that the present crisis is caused by tight money. (You could also choose to see Austrian business cycle theory as a growth theory that explain secular swings in real GDP, but that is not a business cycle theory).

Austrians and keynesians disagree on the policy response to the crisis. The Austrians want “liquidation” and the keynesians want to use fiscal policy (G) to fill the hole left empty by the drop in C and I in (1). This might actually also explain why “Austrians” often resort to quasi-moralist arguments against monetary or fiscal easing. In the Austrian model it would actually “work” if fiscal or monetary policy was eased, but that is politically unacceptable so you need to come up with some other objection. Ok, that is maybe not fair, but that is at least the feeling you get when you listen to populist part of the “Austrian movement” which is popular especially among commentators and young libertarians around the world – the Ron Paul crowd so to speak.

If people understood that our starting point should be (2) rather than (1) then people would also get a much better understanding of the monetary transmission mechanism. It is not about changes in interest rates to change C or I or changes in the exchange rate to change net exports (X-M). (Note of course in (1) M means imports and in (2) M means money). If we focus on (2) rather than (1) we will understand that a devaluation impact nominal demand by changes in M or V – it is really not about “competitiveness” – its about money.

So what we really want is a textbook that starts out with Arrow–Debreu in microeconomics and then move on (2) and macroeconomics. Imagine if economics students were not introduce to the mostly irrelevant national account identity (1) before they had a good understand on the equation of exchange (2)? Then I am pretty sure that we would not have these endless discussions about fiscal policy and most economists would then readily acknowledge that recessions are always and everywhere a monetary phenomenon.

————

PS I am of course aware this partly is a caricature of both the Austrian and the keynesian position. New Keynesians are more clever than just relying on (1), but nonetheless fails really to grasp the importance of money. And then some modern day Austrians like Steve Horwitz fully appreciate that we should start out with (2) rather than (1). However, I am not really sure that I would consider Steve’s macro model to be a Austrian model. There is a lot more Leland Yeager and Clark Warburton in Steve’s model than there is Rothbard or Hayek. That by the way is no critique, but rather why I generally like Steve’s take on the world.

PPS Take a Scott Sumner’s discussion of Bank of England’s inflation. You will see Scott is struggling with the BoE’s research departments lack of understanding nominal vs real. Basically at the BoE they also start out with (1) rather than (2) and that is a central bank! No surprise they get monetary policy wrong…
