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.


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.

A wannabe robojournalist. It can't be bargained with. It can't be reasoned with. It doesn't feel pity, or remorse, or fear. And it absolutely will not stop, ever, until it has filed copy. Photograph: Getty Images

France to bulldoze Calais Jungle days after child refugees arrive in the UK

The camp houses thousands. 

Refugees and migrants in Calais began queuing up for buses this morning as the French authorities plan to demolish the "Jungle" camp.

But activists fear that, unless France significantly speeds up its asylum process, the displaced people will simply move to other camps along the northern French coast.

Meanwhile, the first children of Calais brought to the UK under the Dubs Amendment arrived at the weekend.

The camp known as the Jungle, in a wasteland by the port of Calais, is actually the latest manifestation in a series of camps established since 1999, when a French reception centre became too crowded.

However, it has swelled as a result of the refugee crisis, and attempts by residents to sneak onto lorries entering the Channel Tunnel have become daily occurences. The French authorities bulldozed part of it earlier this year.

Ahead of the latest demolishment, which is expected to happen on Tuesday, Clare Moseley, founder of Care4Calais, said: “In February this year over 50 per cent of the camp was demolished and yet six months later the camp is bigger than it has ever been before. 

"This is clear evidence that demolitions do not act as a deterrent.  The refugees come because they have no choice."

Future refugees will go to other camps with even less facilities, she warned.

The camp houses thousands of residents, but because of the authorities' unwillingness to legitimise it, there is no official presence. Instead, the residents must rely on volunteer aid services and have little means to stop intruders entering. 

Although conditions in the camp can be dire, residents have created a high street with basic tent shops and restaurants catering to the needs of its displaced population. Many of those in the camp say they are there because they hope to be reunited with family in Britain, or they have given up on ever being processed by the French authorities. 

After the UK government was pressurised into passing the Dubs Amendment, which provides sanctuary to unaccompanied child refugees, some children from the camp have arrived in the UK. The first group is reportedly mostly girls from Eritrea, who will be processed at a UK immigration centre.

One of the MPs crucial to ensuring the Dubs Amendment delivered, Stella Creasy, said many more still needed help. 

Children reunited with their families under the Dublin Convention arrived in the UK last week, although their arrival was overshadowed by a debate over age checks.
