Everything has a cost, or so the story goes, especially time. In the Greek case we now know an additional item on the mounting bill: the country is back in recession. The issue is who – apart of course from the long-suffering Greeks themselves – will pay the extra costs of the latest imbroglio.
In our model, people advance along at least locally optimal career paths in expansions, and then have to find a new one in recessions. So you’d expect job tenure, marked in green, to reflect the business cycle – people accumulate it during expansions and lose it in recessions – and that’s precisely what we see. In 1996-2000, when unemployment dropped sharply, it was a strongly negative contributor to wage growth. After that, it began to be a positive contribution as the new hires progressively accumulated tenure and advanced along their career paths. We also see a bit of this after the .com crash. However, it didn’t become a big negative item after the great financial crisis, perhaps because unemployment didn’t rise as much as expected.
The effect of change in qualifications has been quite surprising; it was negative for most of the boom, and then very positive immediately post-crisis.
From 1999 to 2007, workers changing between occupations seems to have been a significant contributor to wage growth (about +0.2% a year). Between 1996 and 2002, workers changing between industries was a positive contribution, but it then swung negative between 2002 and 2006, before becoming positive again in 2007.
During the great financial crisis, it was significantly negative, and it then became positive in the recovery. Since then, it’s disappeared as a factor. Change between occupations, however, was strongly positive in the crisis, erratic and noisy in the recovery, and since Q1 2013, has become very strongly negative. So has the effect of job tenure. At the moment, the combination of tenure and occupational change accounts for -0.75 percentage points of wage growth. The strong negative tenure effect is comparable to that in the late 90s expansion, implying significant net hiring. The occupational change effect is, however, unprecedentedly awful, and it is increasing.
This is consistent with the perverse selection I proposed in the original post. The big difference between now and the 90s experience, though, is that the occupational shift effect is much bigger.
Which is also consistent with making Jobseekers’ Allowance claimants stand around Finsbury Park station wearing a hi-viz vest to no particular purpose.

One of the more intriguing aspects of the whole modern Greek drama is the tragicomic way the country seems to be constantly condemned to live out well known themes which come from its own mythology. The latest example is the way what was once the cradle of European civilization has allowed itself to be converted into the role model for everything its fellow Europeans are not. Or at least, this is the story we are supposed to believe. Continue reading
The WSJ’s Simon Nixon spelled it out for us in his “QE is Working Better than the ECB Dared Hope” article: “one month into the ECB’s €1 trillion ($1.06 trillion) quantitative-easing program, and ECB President Mario Draghi was only too happy to take credit for a remarkable turnaround in the economy’s fortunes at Wednesday’s news conference.” And he goes on to give examples:
“Growth forecasts have been continually revised up since January when the program was announced: the International Monetary Fund said this week it now expects the eurozone to grow by 1.5% in 2015. Business and consumer confidence are the highest since 2007. Bank lending is finally picking up.”
“The strongest growth is coming from former crisis countries: Spain is forecast to grow by up to 3% and Ireland up to 4% this year. Meanwhile German policy makers fret that with growth likely to hit 2.5%, the economy may overheat.”
Naturally, as he also says, “not all of this can be traced to quantitative easing.” But then, here comes the point: “Indeed, if the ECB had delayed its decision on quantitative easing until March, as the Bundesbank had urged, it may have concluded it didn’t need to buy any bonds at all.” Continue reading
They say the first rule of editing is “kill your darlings”. The first rule of science, however, is “sacrifice your darlings humanely in accordance with the research ethics committee guidelines, but keep their brains for further investigation”. So it is with this post. Per Mason, apparently the GFC looks a lot different to past recessions and it’s important to include the full span of the ECEC data back to 1986. So here goes.
The ECEC civilian workers series doesn’t go back to 1986, and neither does all workers, so I picked on the series for “private industry” – after all you’d expect public sector employment to be less responsive to the business cycle by definition – which does. The orange dots on the chart mark ECEC data points, while the blue ones mark the composition-weighted ECI series for private industry. ECEC after 2002 is quarterly, and is averaged to give an annual figure.
The big orange outlier is 2002. ECEC was issued as a slightly different series in 2002-2003, so perhaps we should exclude that one. I’ve plotted regression lines for the two series, orange and blue respectively, and for ECEC excluding 2002, black.
As you can see, ECI is still more cyclical than ECEC (R^2=0.33 vs 0.03 – ten times as much). Excluding 2002 helps a bit, but not enough (R^2=0.33 vs 0.11, three times as much). The correlation between the change in ECEC for the private sector and the output gap is 0.19, and that between private sector ECI and the output gap is 0.58. The blue outlier is 1985-1986.
Purely visually, it looks like the difference between the two series is in fact greatest in the 1980s, but any effect is accounted for by three data points (’86, ’87, ’88) and in any case, it seems to have disappeared 30 years ago. Alternatively, the BLS has changed the method it uses to collect ECEC several times in that period and this might be an artefact.
Mariano Rajoy is a man who is not shy when it comes to being controversial, as the storm surrounding his stance over the recent Greek bailout negotiations clearly illustrates (and here). So it is perhaps not surprising that he did not notably blush when he informed a Madrid audience recently that “In many ways, the crisis is history.” Such was the storm that followed that he was forced to at least partially retract the offending phrase after a meeting with union officials some four days later. “In many ways the crisis is history, but its consequences are not,” he clarified.
Of course all of this is mainly political rhetoric at the start of what is set to be an election year, but still, it does raise interesting questions. Where exactly is Spain? What is the outlook for the future? Is the country still in crisis, or is it, as Rajoy 2.0 suggests simply suffering from the legacy of an earlier one? These questions are not as easy to answer as they seem at first sight, nonetheless in what follows I will take a shot at it. Continue reading
Just to follow up on this post, a simple test of the model would be to check if the ECEC (i.e. not normalised for compositional shifts) wages series is strongly correlated with the output gap. Output gap is easy enough – real potential GDP and real GDP are in FRED, and we convert this to a gap expressed in % of GDP:
Looks like a nice smooth correlation, and in fact the correlation coefficient is a very decent 0.51 for the annual data from 1991 to 2014. For the period 2003-2014 I’ve averaged the quarterly observations. But that’s just the classical effect, right? We need to compare the two indices. Here’s a plot with both series from 2002 to 2014 against the output gap.
It doesn’t look like I can replicate the result that the ECEC is more cyclical than the ECI, at least for the period 2002-2014. The correlation between the annual change in ECI and the output gap for that period is 0.83 and that for ECEC is 0.73. The covariance in ECEC is higher than ECI but both are really low (0.03 and 0.01).
JW Mason has an interesting discovery among the data. Specifically, it looks like the US data series for wages, normalised for shifts in the composition of jobs, is much less cyclical than the raw data. In other words, the business cycle seems to affect wages through composition shifts. In recessions, people lose jobs and eventually get hired back into ones with lower productivity and pay than they had before. People who manage to stick to their jobs through the crisis don’t see much difference. In booms, people who lose their jobs (or quit) tend to get hired into ones with higher productivity, and pay, than they had before.
This makes sense. Imagine that people try to pick a job that suits them – or in economicspeak, that maximises their labour productivity. Imagine also that firms try to hire people who suit their requirements. I doubt this will be very difficult. This is a pretty basic market setup, matching workers and vacancies. Now, consider that people tend to acquire skills and knowledge as they work. This might be something exciting, or it might be as dull as someone in sales building up a contacts book. As a result, people will tend to get onto some sort of career path, picking a speciality and getting better at it.
This might be horizontal – people with a highly transferable skill who move across industries – but I think it’s more likely to be vertical. As they gain in skill, knowledge, or just insidership, they are likely to get paid more. We should at least consider that this matches higher productivity. But then, there’s an explosion – suddenly a lot of firms fail, and their employees are on the dole. They now need to search their way back into work. It is likely, at least, that if they have to find it in another sector or even another firm they will lose some of the human capital they acquired in the past. The unemployed are suddenly driven off their optimal productivity path, and are usually under pressure to take any job that comes along, no matter how suboptimal. Until they get back to where they were before the crisis, on their new paths or on their old ones, the economy will forego the difference between their potential and actual production. You could call it an output gap, but that’s taken, so let’s call it the snakes-and-ladders model.
This, in itself, is enough to explain why unemployment is a thing – you can’t price yourself back into a job with a firm that has gone bust – and why productivity might be depressed for some time post-crisis. In the long term people will climb the ladder again, but this is deceptive. Society, and even firms, can think of a long term. Individuals cannot, as life is short. As the man said – in the long run, we are all dead. Hanging around at reduced productivity is a waste of your time. The recovery phase represents a substantial deadweight loss of production to everyone, concentrated on the unemployed. And there are dynamic effects. Contact books get stale, and technology changes, so the longer people stay either unemployed or underemployed, the bigger the gap. This little model also gives us hysteresis.
But we can go further with the snakes-and-ladders model. Markets, we are often told, are information-processing mechanisms. Let’s look at this from a Diego Gambetta-inspired signalling perspective. The only genuinely reliable way to know if someone is any good at a job is to let them try. I have, after all, every reason to pad my CV, overstate my achievements, and conceal my failures. The only genuinely reliable way to know if someone is an acceptable boss is to work for them. They have every reason to talk in circles about pay and repress their authoritarian streak.
In a tight labour market, people move along close-to-optimal career paths. In doing so, they gain both experience, and also reputation, its outward sign. Importantly, they also gain information about themselves – you don’t know, after all, if you can do the job until you try. The same process is happening with firms and with individual entrepreneurs or managers. Because the information is the product of actual experience, it is costly and therefore trustworthy.
Now let’s blow the system up. We introduce a shock that causes a large number of basically random firms to fail and sack everyone. Because the failure of these firms is not informative about the individuals in them, the effect is to destroy the accumulated information in the labour market. Whatever the workers knew about Bust plc is now irrelevant. In so far as they’re now looking for jobs outside the industry, what Bust plc knew about them is also irrelevant. In the absence of information, the market for labour is now in an inefficient out-of-equilibrium state, where it will stay until the information is re-created. Walrasian tatonnement, right?
This explains an important point in Mason’s data that we’ve not got to yet. Why should people thrown off their career paths take much lower productivity jobs? You don’t need much information to know if someone can mow the lawn. In the post-crisis, disequilibrium state, low productivity jobs are privileged over high productivity jobs.
It strikes me that this little model explains a number of major economic problems. The UK’s productivity paradox, for example, is nicely explained by a huge compositional shift, in part driven by labour market reforms designed to make the unemployed take the first job-ish that comes along. Students who graduate into a recession lose out by about $100,000 over their lives. Verdoorn’s law, the strong empirical correlation between productivity and employment, also seems pretty obvious. Axel Leijonhufvud’s idea of the corridor of stability also fits. In the corridor, the market is self-adjusting, but once it gets outside its control limits, anything can happen.
And, you know, despite all the heterodoxy, it’s microfounded. Workers and employers are entirely rational. Money is just money. It’s not quite simple enough to have a single representative agent, because it needs at least two employers and two workers with dissimilar endowments, but it doesn’t need any actors who aren’t empirically observable.
It also has clear policy implications. If the unemployed sit it out and look for something better, you would expect a jobless recovery and then a productivity boom – like the US in the 1990s. If the unemployed take the first job-like position that comes along, you would expect a jobs miracle with terrible productivity growth, flat to falling wages, and a long period of foregone GDP growth. Like the UK in the 2010s. And if your labour market institutions are designed to prevent the information destruction in the first place, with a fallback to Keynesian reflation if that doesn’t cut it? Well, that sounds like Germany in the 2010s.
Call it Hayekian Keynesianism. Macroeconomic stabilisation is vital to keep the information-processing function of the labour market from breaking down.
That said, I wouldn’t be me if I didn’t point out that there are a whole lot of structural forces here that discriminate against specific groups. The post-crisis skew to low productivity jobs wouldn’t work, after all, if workers weren’t forced sellers of labour to capitalists. And there is one very large group of people who tend to get kicked off their optimal career path with lasting consequences. They’re about 50% of the population.
“After the Great Depression, secular stagnation turned out to be a figment of economists’ imaginations……..it is still too soon to tell if this will also be the case after the Great Recession. However, the risks of secular stagnation are much greater in depressed Eurozone economies than in the US, due to less favourable demographics, lower productivity growth, the burden of fiscal consolidation, and the ECB’s strict focus on low inflation.”

Finland’s economy has been attracting a lot of interest of late. And not for the right reasons, unfortunately. The economy in a country previously renowned for being highly placed in the World Bank’s “Ease of Doing Business Index” has just contracted for the third consecutive year. Once famous for being a symbol of “ultra competitiveness” (it came number 4 in the latest edition of the WEF Global Competitiveness Index) the country is now fast becoming the flagship example of another, less commendable, phenomenon: secular stagnation.The origins of the theory of secular stagnation go back to the US economist Alvin Hansen (see here) who first used the expression in the 1930s. The hallmark of secular stagnation, he said, was a series of sick “recoveries which die in their infancy and depressions which feed on themselves and leave a hard and seemingly immovable core of unemployment.” This seems to fit the Finish case to a T.

What matters isn’t what you think should happen, it’s what others think will happen that counts.
Funny days these, the world seems to be constantly turning upside down. I could be talking about the arrival of negative interest rates in many European economies, but I’m not. What I have in mind is the crossover that seems to be taking place in the perceived fortunes of the US and the Euro Area economies. At the end of 2014 it was all “Europe bad, USA good” to the point that most observers were expecting an imminent rate rise from the Federal Reserve, even while the Euro was in such a bad state that ECB was being steadily pushed – kicking and screaming – towards a full blown programme of sovereign bond buying QE.
