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.

By refusing to stand down, Jeremy Corbyn has betrayed the British working classes

The most successful Labour politicians of the last decades brought to politics not only a burning desire to improve the lot of the working classes but also an understanding of how free market economies work.

Jeremy Corbyn has defended his refusal to resign the leadership of the Labour Party on the grounds that to do so would be betraying all his supporters in the country at large. But by staying on as leader of the party and hence dooming it to heavy defeat in the next general election he would be betraying the interests of the working classes this country. More years of Tory rule means more years of austerity, further cuts in public services, and perpetuation of the gross inequality of incomes. The former Chief Secretary to the Treasury, Seema Malhotra, made the same point when she told Newsnight that “We have an unelectable leader, and if we lose elections then the price of our failure is paid by the working people of this country and their families who do not have a government to stand up for them.”

Of course, in different ways, many leading figures in the Labour movement, particularly in the trade unions, have betrayed the interests of the working classes for several decades. For example, in contrast with their union counterparts in the Scandinavian countries who pressurised governments to help move workers out of declining industries into expanding sectors of the economy, many British trade union leaders adopted the opposite policy. More generally, the trade unions have played a big part in the election of Labour party leaders, like Corbyn, who were unlikely to win a parliamentary election, thereby perpetuating the rule of Tory governments dedicated to promoting the interests of the richer sections of society.

And worse still, even in opposition Corbyn failed to protect the interests of the working classes. He did this by his abysmal failure to understand the significance of Tory economic policies. For example, when the Chancellor of the Exchequer had finished presenting the last budget, in which taxes were reduced for the rich at the expense of public services that benefit everybody, especially the poor, the best John McConnell could do – presumably in agreement with Corbyn – was to stand up and mock the Chancellor for having failed to fulfill his party’s old promise to balance the budget by this year! Obviously neither he nor Corbyn understood that had the government done so the effects on working class standards of living would have been even worse. Neither of them seems to have learnt that the object of fiscal policy is to balance the economy, not the budget.

Instead, they have gone along with Tory myth about the importance of not leaving future generations with the burden of debt. They have never asked “To whom would future generations owe this debt?” To their dead ancestors? To Martians? When Cameron and his accomplices banged on about how important it was to cut public expenditures because the average household in Britain owed about £3,000, they never pointed out that this meant that the average household in Britain was a creditor to the tune of about the same amount (after allowing for net overseas lending). Instead they went along with all this balanced budget nonsense. They did not understand that balancing the budget was just the excuse needed to justify the prime objective of the Tory Party, namely to reduce public expenditures in order to be able to reduce taxes on the rich. For Corbyn and his allies to go along with an overriding objective of balancing the budget is breathtaking economic illiteracy. And the working classes have paid the price.

One left-wing member of the panel on Question Time last week complained that the interests of the working classes were ignored by “the elite”. But it is members of the elite who have been most successful in promoting the interests of the working classes. The most successful pro-working class governments since the war have all been led mainly by politicians who would be castigated for being part of the elite, such as Clement Atlee, Harold Wilson, Tony Crosland, Barbara Castle, Richard Crossman, Roy Jenkins, Denis Healey, Tony Blair, and many others too numerous to list. They brought to politics not only a burning desire to improve the lot of the working classes (from which some of them, like me, had emerged) and reduce inequality in society but also an understanding of how free market economies work and how to deal with its deficiencies. This happens to be more effective than ignorant rhetoric that can only stroke the egos and satisfy the vanity of demagogues

People of stature like those I have singled out above seem to be much more rare in politics these days. But there is surely no need to go to other extreme and persist with leaders like Jeremy Corbyn, a certain election loser, however pure his motives and principled his ambitions.
