The Chuck Norris effect, Swiss lessons and a (not so) crazy idea

Here is from The Street Light:

“You may recall that in September the Swiss National Bank (SNB) announced that it was going to intervene as necessary in the currency markets to ensure that the Swiss Franc (CHF) stayed above a minimum exchange rate with the euro of 1.20 CHF/EUR. How has that been working out for them?

It turns out that it has been working extremely well. Today the SNB released data on its balance sheet for the end of September. During the month of August the SNB had to spend almost CHF 100 billion to buy foreign currency assets to keep the exchange rate at a reasonable level. But in September — most of which was after the announcement of the exchange rate minimum — the SNB’s foreign currency assets only grew by about CHF 25 billion. Furthermore, this increase in the CHF value of the SNB’s foreign currency assets likely includes substantial capital gains that the SNB reaped on its euro portfolio (which was valued at about €130 bn at the end of September), as the CHF was almost 10% weaker against the euro in September than in August. Given that, it seems likely that the SNB’s purchases of new euro assets in September after the announcement of the exchange rate floor almost completely stopped.”

This is a very strong demonstration of the power of monetary policy when the central bank is credible. This is the Chuck Norris effect of monetary policy: You don’t have to print more money to ease monetary policy if you are a credible central bank with a credible target. (Nick Rowe and I like this sort of thing…)

And now to the (not so) crazy idea – if the SNB can ease monetary policy by announcing a devaluation why can’t the Federal Reserve and the ECB do it? Obviously some would say that not all central banks in the world can devalue at the same time – but they can. They can easily do it against commodity prices. So lets say that the ECB, the Federal Reserve, the Bank of Japan, the Bank of England and the SNB tomorrow announced a 15% devaluation against commodity prices (for example the CRB index) and that they will defend that one sided “peg” until the nominal GDP level returns to their pre-Great Recession trend levels. Why 15%? Because that is more or less the NGDP “gap” in the euro zone and the US.

The clever reader will notice that this is the coordinated and slightly more sexy version of Lars E. O. Svensson’s fool-proof way to escape deflation and the liquidity trap.

Is a coordinated 15% devaluation of the major currencies of the world (with the exception of RMB) a crazy idea? Yes, it is quite crazy and it could trigger all kind of political discussions, but I am pretty sure it would work and would very fast bring US and European NGDP back towards the pre-crisis trend. And for those who now scream at the screen “How the hell will higher commodity prices help us?” I will just remind you of the crucial difference between demand and supply driven increases in commodity prices. But okay, lets say we don’t want to do that – so lets instead do the following. The same central banks will “devalue” 15% against a composite index for stock prices in the US, the UK, the euro zone and Japan. Ok, I know you are very upset now. How can he suggest that? I am not really suggesting it, but I am arguing that monetary policy can easily work and all this “crazy idea” would actually do the trick and bring back NGDP back on track in both the US and Europe.  But you might have a better idea.

Nick, Chuck and the central banks

”Recessions are always and everywhere a monetary phenomena”

At the core of Market Monetarist thinking, as in traditional monetarism, is the maxim that “money matters”. Hence, Market Monetarists share the view that inflation is always and everywhere a monetary phenomenon. However, it should also be noted that the focus of Market Monetarists has not been as much on inflation (risks) as on the cause of recession, as the starting point for the school has been the outbreak of the Great Recession.

Market Monetarists generally describe recessions within a Monetary Disequilibrium Theory framework in line with what has been outline by orthodox monetarists such as Leland Yeager and Clark Warburton. David Laidler has also been important in shaping the views of Market Monetarists (particularly Nick Rowe) on the causes of recessions and the general monetary transmission mechanism.

The starting point in monetary analysis is that money is a unique good. Here is how Nick Rowe describes that unique good.

“If there are n goods, including one called “money”, we do not have one big market where all n goods are traded with n excess demands whose values must sum to zero. We might call that good “money”, but it wouldn’t be money. It might be the medium of account, with a price set at one; but it is not the medium of exchange. All goods are means of payment in a world where all goods can be traded against all goods in one big centralised market. You can pay for anything with anything. In a monetary exchange economy, with n goods including money, there are n-1 markets. In each of those markets, there are two goods traded. Money is traded against one of the non-money goods.”

From this also comes the Market Monetarist theory of recessions. Rowe continues:

“Each market has two excess demands. The value of the excess demand (supply) for the non-money good must equal the excess supply (demand) for money in that market. That’s true for each individual (assuming no fat fingers) and must be true when we sum across individuals in a particular market. Summing across all n-1 markets, the sum of the values of the n-1 excess supplies of the non-money goods must equal the sum of the n-1 excess demands for money.”

Said in another way, recession is always and everywhere a monetary phenomenon in the same way as inflation is. Rowe again:

“Monetary Disequilibrium Theory says that a general glut of newly produced goods can only be matched by an excess demand for money.”

This also means that as long as the monetary authorities ensure that any increase in money demand is matched one to one by an increase in the money supply nominal GDP will remain stable (Market Monetarists obviously does not say that economic activity cannot drop as a result of a bad harvest or an earthquake, but such “events” does not create a general glut of goods and labour). This view is at the core of Market Monetarist’s recommendations on the conduct of monetary policy.

Obviously, if all prices and wages were fully flexible, then any imbalance between money supply and money demand would be corrected by immediate changes prices and wages. However, Market Monetarists acknowledge, as New Keynesians do, that prices and wages are sticky.

PS I inspired Nick Rowe to do a post on ”Recessions are always and everywhere a monetary phenomena”. Now I am stealing it back. Nick, I hope you can forgive me.
