Rise of the machines to blame for the lacklustre US recovery

Roombas may look cute, but not when they're taking your job.

The Washington Post's Dylan Matthews highlights a new NBER working paper (£) by Duke University’s Nir Jaimovich and the University of British Columbia’s Henry E. Siu which examines why "jobless recoveries" have become the norm in the US after recent recessions. The short version is that it's all about the robots.

The history of the US labour market since the 1980s has been one of "job polarisation", the authors argue:

[E]mployment is becoming increasingly concentrated at the tails of the occupational skill distribution. This hollowing out of the middle has been linked to the disappearance of jobs focused on “routine” tasks – those activities that can be performed by following a well-defined set of procedures. Autor et al. (2003) and the subsequent literature demonstrates that job polarization is due to progress in technologies that substitute for labor in routine tasks.

At one end of the market are non-routine cognitive jobs, "such as physicians, public relations managers, financial analysts, computer programmers, and economists" (and, one would hope, journalists), while at the other end are non-routine manual occupations "including janitors, gardeners, manicurists, bartenders, and home health aides". Polarisation of the labour market comes from technological improvement replacing people in routine jobs, both manual and cognitive – "secretaries, bank tellers, retail salespeople … dressmakers, cement masons, and meat processing workers."

The classic victim of mechanisation is the factory worker, but it actually hits a far more varied cross-section of careers. Think about automated phone trees replacing secretaries, self-checkouts replacing retail workers, or Oyster cards obviating the need for ticket sales on the London Underground. In fact, according to the Council on Foreign Relations' Edward Alden, manufacturing itself has largely reached maximum automation already:

Manufacturing output in the United States is no longer growing as rapidly as it once was (and as you would expect if technology had simply been replacing workers in factories). Real manufacturing output grew just 15 percent in the 2000s, compared with more than 35 percent in each of the 1970s and 1980s and more than 50 percent in the 1990s.

In itself, this technological change is obviously not something to bemoan – it represents society getting more productivity out of fewer people. If we wanted to follow Keynes, we could literally give all of those people replaced by robots permanent paid holidays and the economy would be no worse off. In actual fact, of course, we realise that improvement not as an increase in leisure time, but as an increase in output: the freshly unemployed are sent out to find more employment, and technological growth results.

This would be relatively pain-free if it happened at a slow, background pace, but that's not the case. Instead, "the decline in routine occupations is concentrated in economic downturns":

Following the peak in 1990, per capita employment in these occupations fell 3.5% to the trough of the 1991 recession, and a further 1.8% during the subsequent jobless recovery. After a minor rebound, employment was essentially flat until the 2001 recession. In the two year window around the 2001 trough, this group shed 6.3% of its employment, before levelling off again. Routine employment has plummeted again in the Great Recession – 12.0% in the two year window around the trough – with no subsequent recovery.

The above chart shows routine employment in the US, with recessions overlaid in shaded pink – and the precipitous decline, and lack of recovery is clear to see.

Gradually, the people who did these routine jobs will filter up or down the skills ladder. The lucky, privileged or smart ones will up-skill and end up in non-routine cognitive work, while the rest will fight for the pool of non-routine manual jobs.

Employment will, eventually, rebound from this slump. As growth returns – helped by the new efficiencies of technological change – there will be more jobs at both the top and bottom of the skills ladder. But as technological progress continues, the safe niches of high- and low-skilled jobs may themselves come under attack.

In May, Martha Gill reported that robots are now writing business stories (which is totally fine), and in June, Rafael Behr wrote about the fear in Downing Street prompted by the rise of the robolawyers:

What happens when the same dynamic creeps up the skills ladder? What are the social and political consequences when white-collar, middle class jobs are increasingly outsourced or done by computers? Plenty of professionals who thought they were immune to the labour market pressures exerted by globalisation will suddenly start to feel very insecure. This is a change that could make itself felt easily within a decade.

What's strange about the whole thing is that, viewed from a macroeconomic point of view, this ought to be good news. If ever fewer people can create ever more "stuff" (be that widgets, legal documents, or business reports), then the potential is for everyone to be better off. The sad reality, of course, is that in the UK and US, the attitude is largely a laissez-faire rejection of the state's responsibility to smooth over the turbulence of structural shifts. But as ministers start to see people like them suffering the same changes that their constituents have for three decades now, there is the chance that real change may finally be possible. There have been attempts to tackle what such a change would mean, from nef's call for a 21 hour week, to the Green Party's suggestion of a Citizen's Income. Or maybe its just more, better targeted, and higher quality opportunities for, and support during, retraining which are needed.

Either way, we've got until the next recession to get some plans in order, or we will have to go through the same routine all over again. And when the robojournalists come for me, I want an exit strategy.

Update

A commenter is concerned about the fact that the above chart uses an unfamiliar y-axis.

The graph is presented as the log value of the employment rate for routine industries, defined in the paper as:

“Sales and related occupations”, “office and administrative support occupations”, “production occupations”, “transportation and material moving occupations”, “construction and extraction occupations”, and “installation, maintenance, and repair occupations”.

Employment rate rather than employment level is used so that the effect the authors are discussing is not masked by population increases. I've charted the sum of the routine employment level as well as the sum of the routine employment level divided by the working age population (roughly equivalent to employment rate), which ought to demonstrate why the latter is used.

As for taking the log value, rather than the absolute percentage, we do that because when comparing different percentages, the log rate evens out differences between changes at high percentages and changes at low percentages. The difference between 2% and 1% is one percentage point, and the difference between 20% and 10% is ten percentage points, but the difference between both log(20%) and log(10%), and log(2%) and log(1%), is 0.3.

I believe only Yvette Cooper has the breadth of support to beat Jeremy Corbyn

All the recent polling suggests Andy Burnham is losing more votes than anyone else to Jeremy Corbyn, says Diana Johnson MP.

Tom Blenkinsop MP on the New Statesman website today says he is giving his second preference to Andy Burnham as he thinks that Andy has the best chance of beating Jeremy.

This is on the basis that if Yvette goes out first all her second preferences will swing behind Andy, whereas if Andy goes out first then his second preferences, due to the broad alliance he has created behind his campaign, will all or largely switch to the other male candidate, Jeremy.

Let's take a deep breath and try and think through what will be the effect of preferential voting in the Labour leadership.

First of all, it is very difficult to know how second preferences will switch. From my telephone canvassing there is some rather interesting voting going on, but I don't accept that Tom’s analysis is correct. I have certainly picked up growing support for Yvette in recent weeks.

In fact you can argue the reverse of Tom’s analysis is true – Andy has moved further away from the centre and, as a result, his pitch to those like Tom who are supporting Liz first is now narrower. As a result, Yvette is more likely to pick up those second preferences.

Stats from the Yvette For Labour team show Yvette picking up the majority of second preferences from all candidates – from the Progress wing supporting Liz to the softer left fans of Jeremy – and Andy's supporters too. Their figures show many undecideds opting for Yvette as their first preference, as well as others choosing to switch their first preference to Yvette from one of the other candidates. It's for this reason I still believe only Yvette has the breadth of support to beat Jeremy and then to go on to win in 2020.

It's interesting that Andy has not been willing to make it clear that second preferences should go to Yvette or Liz. Yvette has been very clear that she would encourage second preferences to be for Andy or Liz.

Having watched Andy on Sky's Murnaghan show this morning, he categorically states that Labour will not get beyond first base with the electorate at a general election if we are not economically credible and that fundamentally Jeremy's economic plans do not add up. So, I am unsure why Andy is so unwilling to be clear on second preferences.

All the recent polling suggests Andy is losing more votes than anyone else to Jeremy. He trails fourth in London – where a huge proportion of our electorate is based.

So I would urge Tom to reflect more widely on who is best placed to provide the strongest opposition to the Tories, appeal to the widest group of voters and reach out to the communities we need to win back. I believe that this has to be Yvette.

The Newsnight focus group a few days ago showed that Yvette is best placed to win back those former Labour voters we will need in 2020.

Labour will pay a massive price if we ignore this.

Diana Johnson is the Labour MP for Hull North.
