Odds and Sods

March 27, 2014 8 comments

A few things worth linking to, about which I have little to say:

1.  Martin Weale’s speech from last week, “Slack and the labour market” is excellent.  Weale estimates a 1.1% shortfall in total hours worked, accounting for over- and under-employment.  This translates to a 0.8% shortfall in real GDP due to labour market slack.  I would like to see some serious responses to this from supply-side optimists.  One possible line of inquiry is on self-employment, which Weale only addresses briefly.

2. Tony Yates has a very interesting post on “One big hubristic consultancy jargon firework display” as he describes the BoE review.  Worth a read if you are interested in BoE politics, as is Tony’s blog.

3. The John Mills/Civitas “There is an alternative” paper is out, and is very strange.  Mills wants to devalue the pound, and sees that being an “alternative” to “monetary policy”.  He doesn’t say how we should devalue the pound, though he favourably references the Yen devaluation under Abenomics.  Mills does (implicitly) want faster NGDP growth and accepts that 3% CPI is a necessary consequence, but believes none of that has anything to do with monetary (or indeed fiscal) policy.  The paper also exhibits a very, very bad fetish for manufacturing.  Ben Southwood already provided a very good critique of the Mills proposal last year.


Inflation, Inflation, 1.7% Inflation

March 26, 2014 3 comments

The UK CPI rate is now down to 1.7% over the twelve months to February 2014, a rambling post follows.  It would be easy to point to the falling CPI rate in the UK and the rising CPI rate in Japan, then point and laugh at idiotic UK politicians celebrating falling inflation… my usual cheap gags, in other words.

It’s never that simple, because we still have to care about supply and demand.  There is little evidence saying that UK aggregate demand growth has slowed over the last twelve months.  There is a lot of evidence that UK aggregate demand is growing faster.  Therefore it is something of a challenge that the inflation rate has fallen.

It is possible to argue that holding aggregate demand growth constant the falling inflation rate is mildly positive supply-side news, and we should grasp such news with both hands.  This is how 99% of newspaper commentators interpret the inflation data anyway.  Keynesians will find some vindication in their view that the inflation rate is related more to the “output gap” than to AD growth, although it comes after six years of UK macro data which generally did the opposite.

Despite some crowing from Tories in the press about the imminent rise of real wages, I see absolutely no indication that hourly wage growth has picked up at all.  If anything, wage growth slowed through 2013.  It remains hard to get reliable high frequency nominal hourly wage data (see previous post) but I can torture the data to give you this little graph:

Imputed Nominal Hourly Wages vs CPI

The data really is tortured to produce that; I take the series for Average Weekly Earnings Regular Pay and divide by average weekly hours, and then apply a 3-month moving average; using the total pay measure inclusive of bonuses produces an extremely volatile result for hourly wages.  Take all this with a pinch of salt.  (What do erratic City bonuses imply for stickiness of hourly wages – arguments in the comment section?)

The other supply-side indicator giving me a little doubt about demand-side revival is a slight fall in total hours worked in recent labour market updates.  I have said it before, but it is hard to overstate how strong the expansion in the UK labour market has been since 2012.  Over the 24 months to October 2013, total hours worked grew 5%.  There is no period of employment growth this strong since the Lawson boom in the late 80s.  The survey evidence for UK employment this year is looking good so there is hopefully no reason to have doubts about the labour market.

But Everybody Knows You Can’t Devalue at the ZLB!

March 24, 2014 2 comments

It’s the liquidity trap, stupid!  Everybody knows you can’t devalue the currency at the ZLB.  Everybody, that is, apart from the central banks of Switzerland, Japan, and the Czech Republic, everybody who has read about forex market gyrations after British, European or American central bankers engage in those almost daily “open mouth operations”, Lars E.O. Svensson, Ben Bernanke, students of economic history, and now Labour Party donor John Mills:

In the paper, which is due to be published this week with the think tank Civitas, Mr Mills has called for an immediate devaluation of the pound. He argues that the UK will be consigned to years of mounting debts and austerity unless manufacturing and productivity levels are boosted. As a major importer of goods, from kitchen gadgets, irons and sports bras, Mr Mills says manufacturing will only return to the UK if the costs come down. De-valuing the pound is the fastest way to achieve this. “We’ve got to get the pound down to make light manufacturing profitable,” he told The Telegraph. “At JML we would buy UK products but we can get everything we sell produced in China for two-thirds of the cost. This is almost entirely an exchange rate issue. And as a result, industrial output just goes down. We can’t pay our way in the world and the economy stagnates – that’s what we’re heading for.”

He said that UK politicians are only using two of the three major ways that a Government can influence the economy – fiscal policy, monetary policy and exchange rates. “Everyone is fixated on the first two and has totally ignored the third,” he said. “And this is the big, big policy mistake that has been made.”

It will be interesting to read the paper; the “real” policy mistake is the choice of nominal anchor, not the level of the pound per se.  I hope the proposal is more substantial than a call for a “discretionary” one-off devaluation, but retention of the CPI target.

Hedonically Unadjusted

March 13, 2014 11 comments

A quick note.  An ONS report today on hedonic quality adjustment carries the following table showing the items for which hedonic quality adjustment is performed in the CPI basket:

Table 2: Hedonic items in the UK consumer price statistics

Item Introduction
PCs 1996 CPI – 2003
RPI – 2004
Digital Cameras 2004 2004
Laptops 2005 2005
Mobile Phones 2005 2007
Smartphones 2011 2011
PC tablets 2012 2013

Source: Office for National Statistics

And that’s it!  (For background on hedonic quality adjustment, the BLS has a nice FAQ.)

I was very surprised to discover that hedonics are only applied to such a small set of items.  The ONS note that the US, by contrast, adjusts for items described as “Clothing, Footwear, Refrigerators, Washing Machines, Clothes Dryers, Ranges & Cooktops, Microwave Ovens, TVs, DVD Players”.

The ONS say they find hedonics complicated and expensive; for goods which are now weighted less than than 1% in the CPI basket, it’s hard not to be sympathetic:

In practice hedonics has proven to be a resource intensive process in the ONS and therefore a costly method. This is due to a number of factors, including the technical nature of the method and the large volume of price and product attribute data that needs to be collected and managed for the production of each hedonic model. Additionally, each hedonic model is updated several times a year to stay relevant to technology changes (for example the introduction of Windows 8 in 2012) which compounds the work involved.

Those who believe that “the price index” captures something real, tangible, and objectively measurable, should be wondering how it is possible to make an objective assessment of the change in PC quality taking account of the “introduction of Windows 8″!

If House Prices are The Key to Full Employment…

March 12, 2014 Leave a comment

What’s the state of UK macro according to the NIESR?

Recent GDP growth has been driven by domestic demand growth, especially consumer spending, which contributed 1.6 percentage points to growth in 2013. This has come despite further falls in real consumer wages. We expect consumer spending to remain the key driver of recovery in 2014 and 2015, supported by continued buoyancy in the housing market. House prices have seen a dramatic rise throughout the year, concentrated in London and the South East. There is considerable uncertainty over the magnitude of the impact of the second Help to Buy Scheme: stronger house price inflation would lead to even stronger consumer spending growth in 2014.

That is from last month, I quote it only because it’s typical of what City commentators are saying about UK macro.  It is interesting how ZLB macro narratives change in the UK.  It appears to me we have have shifted into phase three:

1) In Phase 1 it was asserted that monetary policy will have no effect at the ZLB – it’s a liquidity trap – printing money is pushing on a string.  Ergo, fiscal fiscal fiscal.

2) In Phase 2 it was accepted that in fact monetary policy will have an effect, but it will “only boost asset prices”, it will not help the “real economy.”  Boosting asset prices had “distributional effects” and was zero-sum: rich people owning assets gained, poor people lost out.  After all, if house prices go up, housing is “less affordable”!  Similarly monetary policy could obviously boost commodity prices – again a bad thing for the little people who want to consume those commodities.  Phase 2 was monetary policy viewed as creating supply-side inflation.  Fiscal policy, in contrast, could build real things like bridges and ergo was a better idea.

3) In Phase 3 there is a recognition that boosting asset prices does have effects on the real economy but this was probably a bad thing because it’s “unsustainable”, and it’s also due to fiscal policy in any event.

It is not obvious to me why any level of house prices would be “unsustainable” any more than any level of consumer prices would be “unsustainable”.  It’s just a price index. If macroeconomists really believe that house prices are really the key (or a key?) to boosting real growth and employment – then why not have the Bank of England target the house price index?

There is nothing magical about stabilising the CPI rate, but the HPI is special…. if only we’d known this in 2010!  Worried about the effects of fiscal austerity on employment?  Never mind, have the Bank of England target 20% y/y house price inflation, which will boost consumption and “drive the recovery”.

ACEVO on the Youth Unemployment Crisis

March 6, 2014 1 comment

I’ve been intending to trawl reports on UK youth unemployment to see how they consider the effect of the minimum wage.  Since I already kicked the hornets nest I may as well now go all-in.

ACEVO describes itself as “the Association of Chief Executives of Voluntary Organisations” and “the leading voice for chief executives in the third sector”; they produced a study in 2011 named “Youth unemployment: the crisis we cannot afford” (pdf) from a commission chaired by David Miliband.

To their credit, the authors do seriously consider the effect of the minimum wage, and commissioned a short study by Jack Britton, who appears to be a postgrad at Bristol University.  The study itself is delegated to an appendix, but the report says summarizes the conclusion like this:

Our analysis concludes that theories about the impact of immigration, work disincentives arising from benefit rates and an overgenerous minimum wage are largely red herrings in the debate about youth unemployment.

I’ll quote a large passage from Mr. Britton’s study (pp.120 onwards) looking at how average wages moved between age groups, since it is worth reading, and I don’t want to cherry-pick:

The growth rates of the NMW are shown alongside the growth rates in overall earnings for each of the three age bands in Figure 11. The figure shows that wage growth for the three groups was very similar in both the 2004-2007 period and in the 1999-2004 period, despite the introduction of the minimum for 16-17 year olds in 2004. Because there is no unusual upward shift in wages of 16 and 17 year olds after the introduction of the NMW, it seems unlikely that the wage was set at a level that would significantly affect employment.  The same is true for 18-20 year olds; it seems unlikely that between 2004 and 2007 the minimum wage began to bite, as there is no unusual pattern in average wage growth.

However in the 2007-2010 period, the growth rates of average wages do begin to differ by age group; growth in wages amongst those aged over 21 is far higher than amongst the other two age groups. This is also reflected in Figures 10 and 11, which show respectively the proportion of 16-17 year olds and the proportion of 18-20 year olds in work being paid within various pay ranges. It is clear from both figures that the proportion of young people being paid the minimum wage for their respective age groups increased significantly between 2007 and 2010. (This is shown by the increase in the size of the thick blue area in Figure 10 and the thick red area in Figure 11).

The evidence therefore suggests that companies made limited use of the NMW upon its introduction, but have started to in the wake of the 2008 recession. In other words, prior to the recession it seems the NMW was non-binding, but that it now is, or is starting to. This suggests that the NMW had a limited role in the pre-recessional rise in the NEET rate, but that it now might start to have an important influence.

That looks not unreasonable to me.  But I am confused about how the report’s authors have taken a study which says the minimum wage “might start to have an important influence” since 2008, and concluded the effect of the minimum wage is “largely a red herring”.  Those two phrases do not mean the same thing at all.

The second thing Mr. Britton looks at is sectoral shifts of job creation, where he says:

The table shows that the two sectors where the most jobs were created between 2004 and 2007 were the Public and the Financial Sectors. Although these sectors employ around 30% of 16-24 year olds between them, these people are typically less vulnerable to unemployment, as they are older (they employ 30% of 16-24 year olds, but only 20% of 16-21 year olds) and better qualified (the LFS data suggest 60% of people employed in these sectors have five or more GCSEs, compared to the sample average of 51%). The depression of jobs in sectors in which vulnerable young people typically work is likely to be more important; although it is difficult to precisely estimate the proportion of the rise in the NEET rate since 2004, it seems that this sectoral shift is quite important; potentially contributing more than 30% of the overall rise.

Again, I am confused about how this might be interpreted as evidence that the minimum wage is “largely a red herring”.  It seems to me that a “depression of jobs in sectors in which vulnerable young people typically work” would be a perfectly natural effect of raising the minimum wage for young people.

If the evidence for the absence of a link between youth unemployment and the NMW is so compelling, as many insist, I am left wondering why the ACEVO report commissioned a study which appears to provide evidence that there is such a link, and then, uh, “largely” ignores that result.  My trawling will continue.

“The ECB has Delivered” (A Depression)

March 4, 2014 11 comments

I liked the heading used in Draghi’s speech this week

Five years of monetary policy – the ECB has delivered

In the last five years, the ECB has continued to take the necessary measures with a view to maintaining price stability in the euro area.

The narrative for 2011 is fun:

Initially, while the economic impact of the sovereign debt crisis was limited and largely confined to vulnerable economies, the rapid global recovery put upside pressure on energy prices. This drove up inflation also in the euro area. We decided to raise interest rates in early 2011 given upside risks to the medium term inflation outlook stemming from energy prices and from ample monetary liquidity.

So you raised rates to fight an energy supply shock and “ample monetary liquidity”.  How did that work out?

However, the sovereign debt crisis deepened and the euro area entered a second recession.

Oh.  “However” is a bit out of place, don’t you think?  “Naturally” would work better.  We raised interest rates and naturally the Euro area then entered a second recession.

The inflationary pressures that had emerged before receded.

What a relief, bonuses all round, job well done.

UK 2013 Nominal GDP

February 28, 2014 7 comments

The ONS published the first nominal GDP figure for 2013 Q4 this week, and so we have calendar 2013 too.  Quarterly nominal growth rates continue to be erratic with revisions appearing to move nominal growth around between quarters; so I think we should not to put too much emphasis on the quarterly growth rates.  However, the good news is that NGDP growth has picked up to 4.5% over the year to Q4, from a sub-2% low in the second half of 2012.

Here are the annual growth rates for the last six years, nominal, real and deflator growth, with nominal GVA at basic prices (and deflator) included to show the distortions from indirect tax changes:

Year Nominal
2008 2.4 3.3 -0.8 2.9 3.5
2009 -3.1 2.2 -5.2 -2.4 3.3
2010 4.8 3.1 1.7 3.7 2.0
2011 3.5 2.3 1.1 2.5 1.3
2012 2.0 1.8 0.3 2.0 1.6
2013 3.4 1.6 1.8 3.2 1.5

This graph shows year-on-year quarterly growth:

UK GVA Growth.  Source: ONS ABML ,  CGBV ,  ABMM

Contrary indicators do remain for the “strong nominal growth revival” thesis: growth of nominal imports is fairly slow (2.4% ex oil over 12 months to Q4), as is growth of income tax receipts (OBR says 3.2% ex special factors), and the labour market slowed a little in December, though the LFS monthly sampling effects may distort this.

On that last point, Ben Chu tweeted a good chart showing how unemployment has changed for each of the three cohorts surveyed; the headline unemployment rate being a rolling 3m average.  The fall in the headline rate is driven by two of the cohorts seeing a 0.6% and 0.7% fall in unemployment over just three months to October and November respectively.  Which seems almost too good to be true.  The collapse in the claimant count is perhaps the most convincing reason to believe that the labour market really is doing so well.

Looking forward, the ECFIN ESI confidence indicator rose in February to its highest level since 1989.  Should we call it the Carney boom… or the Osborne boom?  You decide.  But where is that 4%+ output growth?

Minimum Wage, Maximum Derp

February 27, 2014 7 comments

For me one of the most important lessons for British economic policymakers over the last six years should be to fear the interaction of micro with macro, supply-side policies with demand-side policies.

I do not think it is a merely a co-incidence that the worst fall in nominal demand since the 1920s occurred at the same time as a supply-side shock (collapse) in 2008.  All recessions in British history have been driven by tight money aimed at lowering inflation. Was this time different?  It’s not obvious why… CPI rate, September 2008?  5.2%.

And I do not think it is merely a co-incidence that the worst recovery in demand on record has occurred at the same time as inflation has sometimes hovered, sometimes soared above the inflation target.  CPI rate, September 2011?  This is during the time when the Darling/Osborne austerity drive “sucked demand out of the economy.”  That CPI rate in September 2011 was, again, 5.2%.

Here is MPC hawk Martin Weale writing this week:

If wage growth picks up more rapidly than I expect, it will be an indication of inflationary pressure in the economy and Bank rate will need to rise sooner. If wage growth remains subdued, Bank rate should rise more slowly. Because the future is uncertain, we cannot make any promises about where Bank rate will be in a year or two years.

Raising the minimum wage by 3% at a time when hourly wage inflation is 1-2% at best, and is one of the indicators preventing the Bank from screwing up the demand side again… that would surely be an incredibly foolish gamble.

What, exactly, have policymakers learnt from six years of negative supply shocks and disastrous demand-side outcomes?  Have we even learnt anything about wages, nominal shocks and employment?  It does not appear so.

So sure, let’s try another supply shock.  Maybe we’ll get “lucky” and the labour market tightens enough this year that hourly wages pick up, so that a 3% NMW raise doesn’t hurt many more people.  Maybe.

Here is the Low Employment Commission report for 2008 (before the recession):

3.18  The decline in the labour market position of young people has been general across the UK. The proportion of young people not in FTE aged 16–21 who were in employment fell in almost all regions between 1998 and 2007, unlike those aged 22 and over who saw their employment share increase in all areas of the UK except London. However, by European standards, young people’s labour market position in the UK is relatively strong.

Good one!  Our labour market may be doing badly, but just look at Spain!  Those guys are really screwed.  They continue:

Given that employment in the UK has been at record levels, it is difficult to explain why young people have not done better in the labour market. Two significant developments in the labour market in recent years have been the increase in the number of people of pension age becoming economically active and the arrival of predominantly young migrant workers from the European Union accession countries.

It’s “difficult to explain”… right.  A total mystery.  I can’t think what might have caused it, so let’s blame immigrants and old people, those are surely the most “significant developments” in the British labour market in the years to 2008.  If anybody does have any better ideas about what happened, be sure to write to Card, Krueger, Dube, etc.

What’s Happening to UK Hourly Wages?

February 24, 2014 1 comment

In the UK the spotlight is usually on the weekly wage measure produced by the ONS, Average Weekly Earnings.  Scott Sumner tells us to focus on hourly wages.  Why?  I think the heart of the theory is that the hourly wage is a stickier price.  Weekly wages can adjust via a change in hours, or the hourly wage rate.

In this post I’ll take a look at the hourly wage data.  The ONS do not produce an “official” time series for mean hourly wages; but we can get to the data by a number of different routes:

  1. The Annual Survey of Hours and Earnings.  This survey should provide the most reliable data for employed workers, and provides the gross mean hourly earnings (amongst others) from a survey of employers.
  2. The Labour Force Survey.  Every quarter the Labour Market Statistics provide an update to a measure of mean gross hourly earnings (table “EARN08″) from the LFS.  This data is known to underestimate the mean, it excludes workers earnings more than £100/hour.
  3. The monthly labour market update provides both an estimate of Average Weekly Earnings plus average weekly hours, again from the LFS.  A simple matter of division should give us the mean hourly wage.
  4. The national accounts, combined with the Labour Force Survey.  The national accounts tell us aggregate national wage income.  The LFS data tells us total hours worked.  From these two we can calculate mean hourly wages.  I don’t know of any reason to doubt the LFS hours data.  The national accounts do of course get revised.  I am not sure how reliable this measure should be.

The ONS does also have an experimental Index of Labour Cost per Hour series.  This data is also available from Eurostat as the Labour Cost Index.  Annoyingly we are not given the underlying nominal data in either case, only the index level; I will ignore those series for this post.

This is what the four different sources of hourly wages look like:

Estimates of UK Hourly Wage Rates

Estimates of UK Hourly Wage Rates. Source: ONS, Nomis

I was pleasantly surprised that these estimates came out relatively close together; the data from the “EARN08″ table (green line) is as expected an outlier.

Comparing weekly with hourly wages it does appear that a reduction in weekly hours worked in 2009 contributed to the weakness of weekly wages.  Here I’ll stick with the LFS data using average weekly wages/hours as the hourly wage:

Year Average
% Growth

% Growth
2007 4.6 4.9 32.1
2008 3.8 3.5 32.0
2009 1.6 0.0 31.5
2010 1.6 2.3 31.7
2011 2.8 2.4 31.6
2012 0.3 1.3 31.9
2013 1.0 1.3 32.0

Similarly the recovery in average weekly hours since 2011 explains why weekly earnings have grown faster than hourly wages.

On the ASHE measure the average annual growth rate of gross hourly wages was 4.1% between 1997 and 2007, falling to 1.5% between 2008 and 2013.  Remember that 4.1% figure when you are told silly stories about how globalisation reduced wages in Britain, and remember the 1.5% figure when you are told that inflation is the “real threat”.
