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.

RMT poised to rejoin the Labour Party

The transport union is set to vote on reaffiliation to the party, with RMT leaders backing the move.

Plans are being drawn up for the RMT (the National Union of Rail, Maritime and Transport Workers) to reaffiliate to the Labour Party in the wake of Jeremy Corbyn’s significant gains in the general election, the New Statesman has learnt.

The union, which represents tube drivers and other workers across the transport sector, was expelled from the Labour Party under Tony Blair after some Scottish branches voted to support the Scottish Socialist Party instead.

But the RMT endorsed both of Corbyn’s bids for the Labour leadership and its ruling national executive committee backed a Labour vote on 8 June.

Corbyn addressed the RMT’s annual general meeting in Exeter yesterday, where he was “given a hero’s welcome”, in the words of one delegate. Mick Cash, the RMT’s general secretary, praised Corbyn as the union’s “long-term friend and comrade”.

After the meeting, Steve Hedley, assistant general secretary at the RMT, posted a picture to Facebook with John McDonnell. The caption read: “With the shadow chancellor John McDonnell arguing that we should affiliate to the Labour Party after consulting fully and democratically with our members”.

The return of the RMT to Labour would be welcomed by the party leadership with open arms. And although its comparably small size would mean that the RMT would have little effect on the internal workings of Labour Party conference or its ruling NEC, its wide spread across the country could make the union a power player in the life of local Labour parties.
