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.

“We can’t do this again”: Labour conference reactions to Jeremy Corbyn’s second victory

Overjoyed members, determined allies and concerned MPs are divided on how to unite.

“I tell you what, I want to know who those 193,229 people are.” This was the reaction of one Labour member a few rows from the front of the stage, following the announcement of Jeremy Corbyn’s victory at the Labour party conference. She was referring to support received by his defeated contender, Owen Smith, who won 38.2 per cent of the vote (to Corbyn’s 61.8 per cent).

But it’s this focus on the leader’s critics – so vehement among many (and there are a lot of them) of his fans – that many politicians, of either side, who were watching his victory speech in the conference hall want to put an end to.

“It’s about unity and bringing us all together – I think that’s what has to come out of this,” says shadow cabinet member and MP for Edmonton Kate Osamor. “It shouldn’t be about the figures, and how many votes, and his percentage, because that will just cause more animosity.”

Osamor, who is supportive of Corbyn’s leadership, is not alone in urging her colleagues who resigned from the shadow cabinet to “remember the door is never shut”.

Shadow minister and member of Labour’s National Executive Committee (NEC) Jon Ashworth – not a Corbyn loyalist, but focusing on making the shadow cabinet work together – shares the sentiment.

Standing pensively in front of the now-empty stage, he tells me he backs shadow cabinet elections (though not for every post) – a change to party rules that has not yet been decided by the NEC. “[It] would be a good way of bringing people back,” he says. “I’ve been involved in discussions behind the scenes this week and I hope we can get some resolution on the issue.”

He adds: “Jeremy’s won, he has to recognise a number of people didn’t vote for him, so we’ve got to unite.”

The former Foreign Secretary Margaret Beckett, another MP on the NEC, is sitting in the audience, looking over some documents. She warns that “it’s impossible to tell” whether those who resigned from Corbyn’s shadow cabinet would be willing to return, and is concerned about talent being wasted.

“We have a lot of excellent people in the party; there are new people now in the shadow cabinet who have had a chance to show their mettle but you need experience as well as ability,” she says.

Beckett, who has urged Corbyn to stand down in the past, hopes “everybody’s listening” to his call for unity, but questions how that will be achieved.

“How much bad blood there is among people who were told that there was plotting [against Corbyn], it’s impossible to tell, but obviously that doesn’t make for a very good atmosphere,” she says. “But Jeremy says we’ll wipe the slate clean, so let’s hope everybody will wipe the slate clean.”

It doesn’t look that way yet. Socialist veteran Dennis Skinner is prowling around the party conference space outside the hall, barking with glee about Corbyn’s defeated foes. “He’s trebled the membership,” he cries. “A figure that Blair, Brown and Prescott could only dream about. On average there’s more than a thousand of them [new members] in every constituency. Right-wing members of the parliamentary Labour party need to get on board!”

A call that may go unheeded, with fervent Corbyn allies and critics alike already straying from the unity message. The shadow justice secretary Richard Burgon is reminding the PLP that, “Jeremy’s won by a bigger margin this time”, and telling journalists after the speech that he is “relaxed” about how the shadow cabinet is recruited (not a rallying cry for shadow cabinet elections).

“If Jeremy wants to hold out an olive branch to the PLP, work with MPs more closely, he has to look very seriously at that [shadow cabinet elections]; it’s gone to the NEC but no decision has been made,” says Louise Ellman, the Liverpool MP and transport committee chair who has been critical of Corbyn’s leadership. “That might not be the only way. I think he has to find a way of working with MPs, because we’re all elected by millions of people – the general public – and he seems to dismiss that.”

“If he sees it [his victory] as an endorsement of how he’s been operating up until now, the problems which led to the election being called will remain,” Ellman warns. “If we’re going to be a credible party of government, we’ve got to reach out to the general electorate. He didn’t say anything about that in his speech, but I hope that perhaps now he might feel more confident to be able to change direction.”

Corbyn may have called for cooperation, but his increased mandate (up from his last stonking victory with 59.5 per cent of the vote) is the starkest illustration yet of the gulf between his popularity in Parliament and among members.

The fact that one attempt at a ceasefire in the party’s civil war – by allowing MPs to vote for some shadow cabinet posts – is in contention suggests this gulf is in danger of increasing.

And then where could the party be this time next year? As Osamor warns: “We should not be looking at our differences, because when we do that, we end up thinking it’s a good thing to spend our summer having another contest. And we can’t. We can’t do this again.”
