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.

How Jim Murphy's mistake cost Labour - and helped make Ruth Davidson

Scottish Labour's former leader's great mistake was to run away from Labour's Scottish referendum, not on it.

The strange revival of Conservative Scotland? Another poll from north of the border, this time from the Times and YouGov, shows the Tories experiencing a revival in Scotland, up to 28 per cent of the vote, enough to net seven extra seats from the SNP.

Adding to the Nationalists’ misery, according to the same poll, they would lose East Dunbartonshire to the Liberal Democrats, reducing their strength in the Commons to a still-formidable 47 seats.

It could be worse than the polls suggest, however. In the elections to the Scottish Parliament last year, parties which backed a No vote in the referendum did better in the first-past-the-post seats than the polls would have suggested – thanks to tactical voting by No voters, who backed whichever party had the best chance of beating the SNP.

The strategic insight of Ruth Davidson, the Conservative leader in Scotland, was to to recast her party as the loudest defender of the Union between Scotland and the rest of the United Kingdom. She has absorbed large chunks of that vote from the Liberal Democrats and Labour, but, paradoxically, at the Holyrood elections at least, the “Unionist coalition” she assembled helped those parties even though it cost the vote share.

The big thing to watch is not just where the parties of the Union make gains, but where they successfully form strong second-places against whoever the strongest pro-Union party is.

Davidson’s popularity and eye for a good photo opportunity – which came first is an interesting question – mean that the natural benefactor in most places will likely be the Tories.

But it could have been very different. The first politician to hit successfully upon the “last defender of the Union” routine was Ian Murray, the last Labour MP in Scotland, who squeezed both the  Liberal Democrat and Conservative vote in his seat of Edinburgh South.

His then-leader in Scotland, Jim Murphy, had a different idea. He fought the election in 2015 to the SNP’s left, with the slogan of “Whether you’re Yes, or No, the Tories have got to go”.  There were a couple of problems with that approach, as one  former staffer put it: “Firstly, the SNP weren’t going to put the Tories in, and everyone knew it. Secondly, no-one but us wanted to move on [from the referendum]”.

Then again under different leadership, this time under Kezia Dugdale, Scottish Labour once again fought a campaign explicitly to the left of the SNP, promising to increase taxation to blunt cuts devolved from Westminster, and an agnostic position on the referendum. Dugdale said she’d be open to voting to leave the United Kingdom if Britain left the European Union. Senior Scottish Labour figures flirted with the idea that the party might be neutral in a forthcoming election. Once again, the party tried to move on – but no-one else wanted to move on.

How different things might be if instead of running away from their referendum campaign, Jim Murphy had run towards it in 2015.
