Why don't wages fall?

"Nominal wage rigidity" is one of the bigger gaps in theoretical economics.

One of the longstanding disconnects between empirical and theoretical economics is the fact of "nominal wage rigidity". This is the fact that, no matter what level inflation is, nominal pay cuts are incredibly rare. Most of the time, economics is concerned with "real" price levels – that is, prices taking inflation into account. That idea leads to the idea of "real" pay cuts – when your wage rises slower than inflation.

But while real pay cuts are relatively easy to force on employees, nominal ones – when the actual numerical value of their salary is reduced – are significantly harder.

In graphical form, that phenomenon looks like this, from the San Francisco Fed:

 

The dashed line represents the distribution on wage changes you would expect to see if the nominal value didn't matter – a lot of businesses cutting wages, and a lot increasing them, with a slight edge to those increasing them – hence the peak of the distribution is slightly to the right of the zero line.

The bars represent the actual wage changes – and that spike at zero is all the people piling up against downward nominal wage rigidity. (If inflation were higher, the peak of the distribution would be further to the right, and that spike would be smaller.)

But why does this happen? The Jacobin's Seth Ackerman, reporting on the downfall of US snack food manufacturer Hostess, quotes Truman Bewley's seminal 1999 book Why Wages Don’t Fall During a Recession. Bewley actually asked employers why they didn't cut wages:

All of the following are quotes from different interviewees: “I have never cut wages.” “I never froze or cut pay, and never will.” “[A pay cut] is out of the realm of consideration.” “Such a thing is just not done.” “I have never cut anyone’s pay.” “I know something real. Never cut wages.” Over and over, the employers talked about disastrous turnover, bad morale, little acts of sabotage that would sap profits and make their lives miserable.

“If I cut pay, people would leave out of rage, even though they have no place to go,” said the owner of a car dealership with 30 employees.

It took a lot of work for Bewley just to find any companies that had cut their workers’ pay. “At the end of most interviews, I asked whether the respondent knew of any firm that had recently cut pay, and few had heard of any,” he wrote. “All but a few accepted wage rigidity as a fact of life.” But after much searching, he did manage to track down 36 businesses that had cut pay in the past half-decade or so, and he was able to gather more detailed information for 16 of them. In 13 of the 16 cases, the pay cuts were 10% or less. Many of the cuts were explicitly temporary. Of the remaining three cases, at least one involved cuts in work hours to make up for the pay cut.

As Ackerman argues in his piece, nominal wage rigidity is a fact of economics, and one that nearly every employer learns to live with, even when times are hard. The argument – much expressed in the case of Hostess, which was forced to close after workers refused to accept a 30 per cent pay cut – that these pay cuts must occasionally be imposed to bring wages to a "competitive" level is thus absurd. The actual way to phrase it would be that the company was uncompetitive. A competitive company doesn't find itself in the position where it needs to push a hail-Mary attempt to desperately reclaim some extra value from its workers even as it knows they are unlikely to relinquish it.

Our union backed Brexit, but that doesn't mean scrapping freedom of movement

We can only improve the lives of our members, like those planning stike action at McDonalds, through solidarity.

The campaign to defend and extend free movement – highlighted by the launch of the Labour Campaign for Free Movement this month – is being seen in some circles as a back door strategy to re-run the EU referendum. If that was truly the case, then I don't think Unions like mine (the BFAWU) would be involved, especially as we campaigned to leave the EU ourselves.

In stark contrast to the rhetoric used by many sections of the Leave campaign, our argument wasn’t driven by fear and paranoia about migrant workers. A good number of the BFAWU’s membership is made up of workers not just from the EU, but from all corners of the world. They make a positive contribution to the industry that we represent. These people make a far larger and important contribution to our society and our communities than the wealthy Brexiteers, who sought to do nothing other than de-humanise them, cheered along by a rabid, right-wing press. 

Those who are calling for end to freedom of movement fail to realise that it’s people, rather than land and borders that makes the world we live in. Division works only in the interest of those that want to hold power, control, influence and wealth. Unfortunately, despite a rich history in terms of where division leads us, a good chunk of the UK population still falls for it. We believe that those who live and work here or in other countries should have their skills recognised and enjoy the same rights as those born in that country, including the democratic right to vote. 

Workers born outside of the UK contribute more than £328 million to the UK economy every day. Our NHS depends on their labour in order to keep it running; the leisure and hospitality industries depend on them in order to function; the food industry (including farming to a degree) is often propped up by their work.

The real architects of our misery and hardship reside in Westminster. It is they who introduced legislation designed to allow bosses to act with impunity and pay poverty wages. The only way we can really improve our lives is not as some would have you believe, by blaming other poor workers from other countries, it is through standing together in solidarity. By organising and combining that we become stronger as our fabulous members are showing through their decision to ballot for strike action in McDonalds.

Our members in McDonalds are both born in the UK and outside the UK, and where the bosses have separated groups of workers by pitting certain nationalities against each other, the workers organised have stood together and fought to win change for all, even organising themed social events to welcome each other in the face of the bosses ‘attempts to create divisions in the workplace.

Our union has held the long term view that we should have a planned economy with an ability to own and control the means of production. Our members saw the EU as a gravy train, working in the interests of wealthy elites and industrial scale tax avoidance. They felt that leaving the EU would give the UK the best opportunity to renationalise our key industries and begin a programme of manufacturing on a scale that would allow us to be self-sufficient and independent while enjoying solid trading relationships with other countries. Obviously, a key component in terms of facilitating this is continued freedom of movement.

Many of our members come from communities that voted to leave the EU. They are a reflection of real life that the movers and shakers in both the Leave and Remain campaigns took for granted. We weren’t surprised by the outcome of the EU referendum; after decades of politicians heaping blame on the EU for everything from the shape of fruit to personal hardship, what else could we possibly expect? However, we cannot allow migrant labour to remain as a political football to give succour to the prejudices of the uninformed. Given the same rights and freedoms as UK citizens, foreign workers have the ability to ensure that the UK actually makes a success of Brexit, one that benefits the many, rather than the few.
