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 problems with ending encryption to fight terrorism

Forcing tech firms to create a "backdoor" to access messages would be a gift to cyber-hackers.

The UK has endured its worst terrorist atrocity since 7 July 2005 and the threat level has been raised to "critical" for the first time in a decade. Though election campaigning has been suspended, the debate over potential new powers has already begun.

Today's Sun reports that the Conservatives will seek to force technology companies to hand over encrypted messages to the police and security services. The new Technical Capability Notices were proposed by Amber Rudd following the Westminster terrorist attack and a month-long consultation closed last week. A Tory minister told the Sun: "We will do this as soon as we can after the election, as long as we get back in. The level of threat clearly proves there is no more time to waste now. The social media companies have been laughing in our faces for too long."

Put that way, the plan sounds reasonable (orders would be approved by the home secretary and a senior judge). But there are irrefutable problems. Encryption means tech firms such as WhatsApp and Apple can't simply "hand over" suspect messages - they can't access them at all. The technology is designed precisely so that conversations are genuinely private (unless a suspect's device is obtained or hacked into). Were companies to create an encryption "backdoor", as the government proposes, they would also create new opportunities for criminals and cyberhackers (as in the case of the recent NHS attack).

Ian Levy, the technical director of the National Cyber Security, told the New Statesman's Will Dunn earlier this year: "Nobody in this organisation or our parent organisation will ever ask for a 'back door' in a large-scale encryption system, because it's dumb."

But there is a more profound problem: once created, a technology cannot be uninvented. Should large tech firms end encryption, terrorists will merely turn to other, lesser-known platforms. The only means of barring UK citizens from using the service would be a Chinese-style "great firewall", cutting Britain off from the rest of the internet. In 2015, before entering the cabinet, Brexit Secretary David Davis warned of ending encryption: "Such a move would have had devastating consequences for all financial transactions and online commerce, not to mention the security of all personal data. Its consequences for the City do not bear thinking about."

Labour's manifesto pledged to "provide our security agencies with the resources and the powers they need to protect our country and keep us all safe." But added: "We will also ensure that such powers do not weaken our individual rights or civil liberties". The Liberal Democrats have vowed to "oppose Conservative attempts to undermine encryption."

But with a large Conservative majority inevitable, according to polls, ministers will be confident of winning parliamentary support for the plan. Only a rebellion led by Davis-esque liberals is likely to stop them.
