## ECB: One Size Fits None

Eurostat just released its flash estimate for inflation in the Eurozone: 0.5% headline, and 0.8% core. We now await comments from ECB officials, ahead of next Thursday’s meeting, saying that everything is under control.

Just this morning, Wolfgang Münchau in the Financial Times rightly said that EU central bankers should talk less and act more. Münchau also argues that quantitative easing is the only option. A bold one, I would add in light of todays’ deflation inflation data. Just a few months ago, in September 2013, Bruegel estimated the ECB interest rate to be broadly in line with Eurozone average macroeconomic conditions (though, interestingly, they also highlighted that it was unfit to most countries taken individually).

In just a few months, things changed drastically. While unemployment remained more or less constant since last July, inflation kept decelerating until today’s very worrisome levels. I very quickly extended the Bruegel exercise to encompass the latest data (they stopped at July 2013). I computed the target rate as they do as

$Target=1+1.5\pi_{core}-1(u-\overline{u})$.

(if you don’t like the choice of parameters, go ask the Bruegel guys. I have no problem with these). The computation gives the following:

Using headline inflation, as the ECB often claims to be doing, would of course give even lower target rates. As official data on unemployment stop at January 2014, the two last points are computed with alternative hypotheses of unemployment: either at its January rate (12.6%) or at the average 2013 rate (12%). But these are just details…

So, in addition to being unfit for individual countries, the ECB stance is now unfit to the Eurozone as a whole. And of course, a negative target rate can only mean, as Münchau forcefully argues, that the ECB needs to get its act together and put together a credible and significant quantitative easing program.

Two more remarks:

• A minor one (back of  the envelope) remark is that given a core inflation level of 0.8%, the current ECB rate of 0.25%, is compatible with an unemployment gap of 1.95%. Meaning that the current ECB rate would be appropriate if natural/structural unemployment was 10.65% (for the calculation above I took the value of 9.1% from the OECD), or if current unemployment was 11.5%.
• The second, somewhat related but more important to my sense, is that it is hard to accept as “natural” an unemployment rate of 9-10%. If the target unemployment rate were at 6-7%, everything we read and discuss on the ECB excessively restrictive stance would be significantly more appropriate. And if the problem is too low potential growth, well then let’s find a way to increase it

## Overheat to Raise Potential Growth?

Update, March 20th: Speaking of ideological biases concerning inflation, Paul Krugman nails it, as usual.

On today’s Financial Times, Phillip Hildebrand gives yet another proof of unwarranted inflation terror. His argument is not new: In spite of the consensus on a weak recovery, the US economy may be close to its potential , so that further monetary stimulus would eventually be inflationary.

He then deflects (?) the objection that decreasing unemployment reflects decreasing labour force participation rather than new employment, by suggesting that it is hard to know how many of the 13 millions jobs missing are structural, i.e.not linked to the crisis. I think it is worth quoting him, because otherwise it would be hard to believe:

However, an increasingly vocal group of observers, including within the Fed, posits that more of the fall in the participation rate appears to have been structural than cyclical, and it was even predictable – the result of factors such as an ageing workforce and the effect of technology on jobs.

(the emphasis is mine). Now look at this figure, quickly produced from FRED data: Read more

## Commission Forecasts Watch – March 2014 Edition

Last week the Commission published its second flash estimates for 2013 GDP growth. This allows to update an earlier exercise I had made on forecast errors by the Commission (around this time last year). This is what I had noticed at the time:

The Commission tends to be overly optimistic, and forecasts turn out to be in general higher than actual values. It should not be like this. While I expect a government to inflate a bit the figures, a non-partisan, technocratic body should on average be correct.
Related, it is also surprising that in November of the same year the Commission is still consistently overoptimistic (yellow bar). Let me restate it. This means that in November 2012 the Commission made a mistake on GDP growth for 2012. November!

I had concluded that there was a likely political bias in the Commission’s forecasts, with excessive optimism used to deflect criticisms of austerity. I also ventured in a quick and dirty estimate of the range for GDP growth in 2013, based on the Commission’s past errors. Actual growth turned out to be -0.5%, i.e. at the lower bound of my range (and below the forecast of the time by the Commission, that was -0.3%). I must nevertheless confess that my range was rather wide…
