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.

The politics of the kiss

From the classical period via the Kremlin to the Clintons: a brief history of political smooching.

Iowa and New Hampshire are behind us. Super Tuesday beckons. For fans of the competitive sport of baby-kissing, this is as good as it gets.

Meanwhile, closer to Britain, kissing’s in our very constitution. Jeremy Corbyn’s future, depending on his success, could involve taking a trip to the Palace to kiss hands as Prime Minister – and as a republican. Being sworn into the Privy Council in November, he even managed a peck on the royal paw, but reportedly stood fast and did not kneel.

Why is there so much snogging in politics? 

Ancient Romans and Persians established – dare we – a pecking order on meeting. This ritual would make it instantly clear if they were equals (full-on, mouthy kiss, the basium), separated by a slight gap (cheeky peck, an osculum), or vast unequals (foot-kissing accompanied by much grovelling). Even heads of state greeted people in this way.

And there was nothing more dramatic – and bizarre – than the socialist fraternal kiss. Kremlinologists would even measure its intensity, to see how close Communist leaders were. The rule was to do three alternate kisses on the cheek, aping the Ancien Régime’s Orthodox Easter greeting. When two leaders were especially chummy – like then Soviet leader Leonid Brezhnev and GDR head Erich Honecker at the 30th anniversary of the GDR in East Berlin in 1979 – the world would witness a big, sloppy lip-plant. Paris Match splashed Régis Bossu’s iconic black-and-white image of the socialist snog across a double-page spread. Le Baiser, they called it.

Nikita Khrushchev, Joseph Stalin’s successor, locked lips with USSR chairman Klim Voroshilov when returning from a US visit in 1959. In July 1937, Stalin planted a decidedly non-frigid one on Ivan Spirin, a polar explorer and state hero.

But Brezhnev was the true practitioner. The joke in Russia went that he described a Warsaw Pact comrade “as a politician, rubbish...but a good kisser!”

Aside from the steamy Kremlin, social kissing on the mouth declined with the Black Death.

The courtly handkuss (kiss on the hand) generally went the same way with the fall of the German and Russian monarchies in 1917-18, though hung on longer in Austria. 

But French president Jacques Chirac made it his trademark, playing to the gallery with French élégance. An Associated Press story from 1967 chronicles the sad plight of European diplomats who had chanced it in Washington. One congressional wife jumped back, claiming she had been bitten; another said a stone was missing from her ring. “Chivalry has its drawbacks,” the story observed.

But back to the babies. We see kissing-as-canvassing in William Hogarth’s 1755 series The Humours of an Election

And in a close-fought 1784 Westminster by-election, we read of 24 women out canvassing with kisses – including the Duchesses of Rutland, Argyll, Ancaster, and (somewhat infamously) Devonshire. 

Kissing voters’ wives – now probably frowned upon by CCHQ – was customary fare for the 18th-century candidate. It’s only in the following century that we see the desexualisation of the electioneering kiss, moving to babies as innocuous. 

In 1836, Charles Dickens has his character Pickwick go to witness a post-Reform Act by-election in Eatanswill. “He has patted the babies on the head,” says the candidate’s election agent, trembling with anxiety. Roar of applause. “He has kissed one of ‘em!” Second roar. “He's kissing ‘em all!” The crowd’s shouts are deafening. And the candidate Slumkey coasts home to Parliament.

US presidents Richard Nixon, Grover Cleveland and Benjamin Harrison forswore baby kissing, grasping for a higher-minded political plane. Bernie Sanders, too. 

But how are the rest of today's politicians doing, kiss-wise?

Barack Obama: After two terms, a kisser to be reckoned with. With adults. Apparently he doesn’t relish kissing babies, and has been called fatally ill-at-ease holding one. Full points for his lucky save with a reticent Aung San Suu Kyi in 2014, ending with a perfectly creditable side-hug and ear-kiss.

Pity Michelle, photographed rolling her eyes as Barack went in for the selfie with, say, Danish Prime Minister Helle Thorning-Schmidt in 2013. (For her part, Michelle fobbed off Silvio Berlusconi with a fully outstretched arm, taking no chances.)

David Cameron: Utterly denied by SamCam after his Tory conference speech in October 2015. Lord Grantham says in Downton he spent most of Eton avoiding the kisses of other boys; clearly, the Prime Minister didn’t get much practice while at school.

Angela Merkel: In her first meeting with Nicolas Sarkozy, out she came with a businesslike German handshake just as he ducked for the Gallic kiss. In a moment of British romantic awkwardness last May, during Cameron’s EU reform tour, we saw the Prime Minister lean in, short of closing the deal, as she pulled back and possibly searched for some new regulations to beat him away with.

Hillary Clinton: Is said to enjoy kissing babies. Is said not to enjoy kissing Bill, as in the 2008 Correspondents’ Dinner when she expertly ducked one from him.  And scored one from Obama instead. But maybe she ought to lay off the baby-kissing: a journal article in Political Psychology suggests voters are 15 per cent less likely to vote for women candidates when their adverts evoke female gender stereotypes.

Donald Trump: In August, his baby-kiss in Alabama went viral – the baby’s mother just a bit too keen, the baby’s confusion mingled with slight fear reflecting the views of many of us. “That baby is us,” wrote blogger Stassa Edwards.

It’s a long road from here to the US election in November. And Cameron can look forward to kissing up to Merkel and a hot summer of Italian, Dutch, and even French kisses too.

So this Valentine’s Day, spare a thought for the babies. And the bureaucrats.
