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.

Europe’s last Blairite: Can Manuel Valls win the French presidency?

He first made a name for himself protesting against halal supermarkets. Now, he could be the man to take down François Hollande.

The election of François Hollande as the president of France in 2012 coincided with the high-water mark of Ed Miliband’s leadership of the Labour Party. That year, Labour posted its best local election results in 17 years, gaining 823 councillors and winning control of 32 councils in a performance that has not yet been surpassed or equalled.

Gazing across the Channel, the Milibandites were given hope. Hollande showed that a wonkish career politician could triumph over a charismatic centre-right incumbent.

The UK’s shattered Blairites looked to a different star rising in French politics: Manuel Valls. At the time of Hollande’s victory, Valls was the mayor of Évry, a small suburb of Paris, where he made a name for himself by campaigning against halal supermarkets.

His father, Xavier, was a Spanish painter and his mother, Luisangela, was Swiss-Italian. They met and married in Paris, and Valls was born in Barcelona while the couple were on holiday.

In 2009 Valls urged the Parti Socialiste (PS) to drop the adjective “socialist” from its name, and he ran for the presidential nomination two years later on what he described as a Blairiste platform. This included scrapping the 35-hour working week, which hardly applies outside of big business and the public sector but carries symbolic weight for the French left. Valls’s programme found few supporters and he came fifth in a field of six, with just 6 per cent of the vote.

Yet this was enough to earn him the post of interior minister under Hollande. While Valls’s boss quickly fell from favour – within six months Hollande’s approval ratings had dropped to 36 per cent, thanks to a budget that combined tax rises with deep spending cuts – his own popularity soared.

He may have run as an heir to Blair but his popularity in France benefited from a series of remarks that were closer in tone to Ukip’s Nigel Farage. When he said that most Romany gypsies should be sent “back to the borders”, he was condemned by both his activists and Amnesty International. Yet it also boosted his approval ratings.

One of the facets of French politics that reliably confuse outsiders is how anti-Islamic sentiment is common across the left-right divide. Direct comparisons with the ideological terrain of Westminster politics are often unhelpful. For instance, Valls supported the attempt to ban the burkini, saying in August, “Marianne [the French symbol] has a naked breast because she is feeding the people! She is not veiled, because she is free! That is the republic!”

By the spring of 2014, he was still frequently topping the charts – at least in terms of personal appeal. A survey for French Elle found that 20 per cent of women would like to have “a torrid affair” with the lantern-jawed minister, something that pleased his second wife, Anne Gravoin, who pronounced herself “delighted” with the poll. (She married Valls in 2010. He also has four children by his first wife, Nathalie Soulié.)

Yet it was a chilly time for the French left, which was sharply repudiated in municipal elections, losing 155 towns. Hollande sacked his incumbent prime minister, Jean-Marc Ayrault, and appointed Valls in his place. He hoped, perhaps, that some of Valls’s popularity would rub off on to him.

And perhaps Valls, a student of “Third Way” politics, hoped that he could emulate the success of Bill Clinton, who turned sharply to the right following Democratic losses in the US 1994 midterm elections and won a great victory in 1996. Under Valls’s premiership, Hollande’s administration swung right, implementing tough policies on law and order and pursuing supply-side reforms in an attempt to revive the French economy. Neither the economic recovery, nor the great victory, emerged.

With the date of the next presidential election set for 2017, Hollande was in trouble. His approval ratings were terrible and he faced a challenge from his former minister Arnaud Montebourg, who resigned from the government over its rightward turn in 2014.

Then, on 27 November, Prime Minister Valls suggested in an interview that he would challenge the incumbent president in the PS primary. After this, Hollande knew that his chances of victory were almost non-existent.

On 1 December, Hollande became the first incumbent French president ever to announce that he would not run for a second term, leaving Valls free to announce his bid. He duly stood down as prime minister on 5 December.

Under the French system, unless a single candidate can secure more than half of the vote in the first round of the presidential election, the top two candidates face a run-off. The current polls rate Marine Le Pen of the Front National as the favourite to win the first round, but she is expected to lose the second.

Few expect a PS candidate to make the run-off. So Hollande’s decision to drop out of his party’s primary turns that contest into an internal struggle for dominance rather than a choice of potential leader for France. The deeper question is: who will rebuild the party from the wreckage?

So although Valls has the highest international profile of the left’s candidates, no one should rule out a repeat of his crushing defeat in 2011.

He once hoped to strike a Blairite bargain with the left: victory in exchange for heresy. Because of the wasting effect of his years in Hollande’s government, however, he now offers only heresy. It would not be a surprise if the Socialists preferred the purity of Arnaud Montebourg.
