Could Central Banks do More during the Crisis?

September 7, 2018 3 comments

I rarely disagree with Martin Sandbu’s Free Lunch. But today’s piece on central banks is one of these cases.

In short, Martin argues that while the main culprit for the slow recovery is fiscal policy, almost everywhere too timid if not outright procyclical (we are all on board on that!), the mistakes of fiscal authorities do not exempt central banks from bearing part of the responsibility. In particular, he dismisses the claim that it was technically impossible to lower long-term interest rates further, and/or bring policy rates even more into negative territory.

I agree with this point. Interest rates could have been lowered further. Nevertheless, I think that this would have made very little difference, because after 2008 central banks were essentially pushing on a string.  This point of disagreement between us can be traced to a different view about what is the liquidity trap.

I recently published a book, La Scienza inutile (a general public account of a century of debates in macroeconomics. For the moment it is in Italian and in French, English translation in progress), in which I discuss the different notions of liquidity trap. Here is the quote (sorry, a bit too long):

 The first source of trouble that Keynes considers is the most extreme, the so-called liquidity trap: `There is the possibility, […] that, after the rate of interest has fallen to a certain level, liquidity-preference may become virtually absolute in the sense that almost everyone prefers cash to holding a debt which yields so low a rate of interest. In this event the monetary authority would have lost effective control over the rate of interest’ (Keynes 1936, p.207). In slightly more technical terms, the interest elasticity of money demand is near-infinite: no matter how much liquidity the central bank injects into the economy, it is entirely hoarded by agents and hence it leaks out of the system in its entirety. Monetary expansion is not effective in lowering interest rates.

There may be different reasons why the economy enters a liquidity trap. Keynes argued, by looking at the great depression, that this usually happens at very low (but not necessarily nil) levels of the interest rate, because in this case agents would expect interest rates to rise in the future and thus would be willing to hold any extra amount of money and postpone the purchase of bonds to the moment when interest rates will be up again. More recently the liquidity trap has been defined as a situation in which the interest rate that equates savings and investment is negative, and therefore cannot be attained by the central bank (the so-called Zero Lower Bound, or ZLB; see e.g. Krugman 2000). This latter definition leaves some room for monetary policy effectiveness: if the central bank manages to trigger the expectation of positive inflation, the real interest rate (the nominal interest rate minus the inflation rate) will become negative and lead to the full employment equilibrium.

So, if we think in terms of ZLB, it exists a real interest rate at which the output gap would be closed. If that interest rate is negative, then it is harder to reach, as central banks need to raise inflation expectations and try to push short term rates as much as possible in negative territory, which requires boldness and creativity (we have seen this). But, once again I agree with Martin on that, this can be done. If instead private expenditure becomes irresponsive to interest rates, the ‘Keynes definition’, then there is little central banks could do. I had noticed, back in 2016, that while it succeeded in easing credit conditions, EMU Quantitative Easing seemed to have done little to boost confidence and expected demand (the ultimate driver of firm’s credit needs). The EMU most recent Bank Lending Survey seems to confirm the prediction of the time. Both chart 4 (enterprises) and chart 12 (households) depict a flat demand for loans, that picks up only when the EMU economic outlook brightens.

This is by no means hard evidence (I am not aware of any papers thoroughly investigating the impact of QE on credit demand). But stylized facts seem to acquit central bankers.

Walls Come Tumbling Down

August 16, 2014 9 comments

Yesterday I quickly commented the disappointing growth data for Germany and for the EMU as a whole, whose GDP Eurostat splendidly defines “stable”. This is bad, because the recovery is not one, and because we are increasingly dependent on the rest of the world for that growth that we should be able to generate domestically.

Having said that, the real bad news did not come from Eurostat, but from the August 2014 issue of the ECB monthly bulletin, published on Wednesday. Thanks to Ambrose Evans-Pritchard I noticed the following chart ( page 53):

The interesting part of the chart is the blue dotted line, showing that the forecasters’ consensus on longer term inflation sees more than a ten points drop of the probability that inflation will stay at 2% or above. Ten points in just a year. And yet, just a few pages above we can read:

According to Eurostat’s flash estimate, euro area annual HICP inflation was 0.4% in July 2014, after 0.5% in June. This reflects primarily lower energy price inflation, while the annual rates of change of the other main components of the HICP remained broadly unchanged. On the basis of current information, annual HICP inflation is expected to remain at low levels over the coming months, before increasing gradually during 2015 and 2016. Meanwhile, inflation expectations for the euro area over the medium to long term continue to be firmly anchored in line with the aim of maintaining inflation rates below, but close to, 2% (p. 42, emphasis added) 

The ECB is hiding its head in the sand, but expectations, the last bastion against deflation, are obviously not firmly anchored. This can only mean that private expenditure will keep tumbling down in the next quarters. It would be foolish to hope otherwise.

So we are left with good old macroeconomic policy. I did not change my mind since my latest piece on the ECB. Even if the ECB inertia is appalling, even if their stubbornness in claiming that everything is fine (see above) is more than annoying, even if announcing mild QE measures in 2015 at  the earliest is borderline criminal, it remains that I have no big faith in the capacity of monetary policy to trigger decent growth.  The latest issue of the ECB bulletin also reports the results of the latest Eurozone Bank Lending Survey. They show a slow easing of credit conditions, that proceed in parallel with a pickup of credit demand from firms and households. While for some countries credit constraints may play a role in keeping private expenditure down (for example, in Italy), the overall picture for the EMU is of demand and supply proceeding in parallel. Lifting constraints to lending, in this situation, does not seem likely to boost credit and spending. It’s the liquidity trap, stupid!

The solution seems to be one, and only one: expansionary fiscal policy, meaning strong increase in government expenditure (above all for investment) in countries that can afford it (Germany, to begin with); and delayed consolidation for countries with struggling public finances. Monetary policy should accompany this fiscal boost with the commitment to maintain an expansionary stance until inflation has overshot the 2% target.

For the moment this remains a mid-summer dream…


End of The Tunnel?

January 30, 2013 3 comments

There are signs of optimism around. Cautiously, policy makers and commentators start discussing the shape (and the fragility) of the future recovery.  Martin Wolf on the Financial Times already speculates on the timing of reversal to a normal state of affairs. Wolf is rightly worried by the temptation to reverse policies too fast, a mistake we made already at the end of 2009, when stimulus plans were reversed into consolidation far too soon.

As a rule of thumb, I’d argue that exceptional involvement of governments in the economy should stop when the private sector is ready to take the witness. Stimulus plans and monetary easing should be rolled back once private spending resumes (or is ready to resume), and when the credit market is sufficiently loose. So the question is, how does private sector behaviour fit, within this moderate optimistic mood? Not too well I am afraid… Read More
