Word of the day: Hysteresis

Too long in a slump, and the slump starts to get permanent.

The Financial Times reports this morning that the Olympics don't seem to be leading to quite the tourist boom expected:

The games have attracted as many as 100,000 foreign visitors [per day] to London – more than in previous Olympics. But, on its own, that number significantly lags behind the estimated 300,000 foreign tourists [per day] who could be expected in a typical year.

As Richard Murphy points out, this means that one of the great hopes for bringing the country out of recession appears to be fading away. Which means the word of the day is hysteresis.

In general terms, hysteresis is similar to intertia; it is the concept that some things which are hard to get going may then require little input to maintain, and even more effort to reverse.

In specific economic terms, it is the theory that persistent levels of high unemployment raise the "natural" rate of unemployment, also known as NAIRU, the non-accelerating inflation rate of unemploymet. This is the level of unemployment at which, under neo-classical economics, inflation stays low and steady. (As a side-note, yes, neo-classical economics holds that a certain amount of unemployment is good. "Full employment" is thus a bad thing, because it leads to spiralling inflation)

Although it's not specifically related to GDP, it is always a fear when dealing with persistent unemployment and long periods of stagnation and recession. The cause of the phenomenon comes when layoffs in a particular sector increase the bargaining power of the remaining workers. as there are fewer of them left, they can demand higher wages, which become "sticky" in nominal terms, if the period of unemployment lasts long enough. If, at the end of the recession, the business then wants to hire new employees, they have to pay them the new, high wage. In practice, this means that either unemployment stays high permanently, or inflation goes up until the value of the high wage is back, in real tems, to where it was.

It doesn't look like we are seeing the "increased wages" part of the problem yet (since wages are very much stagnating), but that hasn't stopped Citigroup's Ajai Chopra warning everyone:

Our analysis of such hysteresis effects shows that the large and sustained output gap, the difference between what an economy could produce and what it is producing, raises the danger that a downturn reduces the economy’s productive capacity and permanently depresses potential GDP.

No, IDS, welfare isn't a path to wealth. Quite the opposite, in fact

Far from being a lifestyle choice, welfare is all too often a struggle for survival.

Iain Duncan Smith really is the gift that keeps on giving. You get one bile-filled giftbag of small-minded, hypocritical nastiness and, just when you think it has no more pain to inflict, off comes another ghastly layer of wrapping paper and out oozes some more. He is a game of Pass the Parcel for people who hate humanity.
For reasons beyond current understanding, the Conservative party not only let him have his own department but set him loose on a stage at their conference, despite the fact that there was both a microphone and an audience and that people might hear and report on what he was going to say. It’s almost like they don’t care that the man in charge of the benefits system displays a fundamental - and, dare I say, deliberate - misunderstanding of what that system is for.
IDS took to the stage to tell the disabled people of Britain - or as he likes to think of us, the not “normal” people of Britain -  “We won’t lift you out of poverty by simply transferring taxpayers’ money to you. With our help, you’ll work your way out of poverty.” It really is fascinating that he was allowed to make such an important speech on Opposite Day.
Iain Duncan Smith is a man possessed by the concept of work. That’s why he put in so many hours and Universal Credit was such a roaring success. Work, when available and suitable and accessible, is a wonderful thing, but for those unable to access it, the welfare system is a crucial safety net that keeps them from becoming totally impoverished.
Benefits absolutely should be the route out of poverty. They are the essential buffer between people and penury. Iain Duncan Smith speaks as though there is a weekly rollover on them, building and building until claimants can skip into the kind of mansion he lives in. They are not that. They are a small stipend to keep body and soul together.
Benefits shouldn’t be a route to wealth and DWP cuts have ensured that, but the notion that we should leave people in poverty astounds me. The people who rely on benefits don’t see it as a quick buck, an easy income. We cannot be the kind of society who is content to leave people destitute because they are unable to work, through long-term illness or short-term job-seeking. Without benefits, people are literally starving. People don’t go to food banks because Waitrose are out of asparagus. They go because the government has snipped away at their benefits until they have become too poor to feed themselves.
The utter hypocrisy of telling disabled people to work themselves out of poverty while cutting Access to Work is so audacious as to be almost impressive. IDS suggests that suitable jobs for disabled workers are constantly popping out of the ground like daisies, despite the fact that his own government closed 36 Remploy factories. If he wants people to work their way out of poverty, he has make it very easy to find that work.
His speech was riddled with odious little snippets digging at those who rely on his department. No one is “simply transferring taxpayers’ money” to claimants, as though every Friday he sits down with his card reader to do some online banking, sneaking into people’s accounts and spiriting their cash away to the scrounging masses. Anyone who has come within ten feet of claiming benefits knows it is far from a simple process.
He is incredulous that if a doctor says you are too sick to work, you get signed off work, as though doctors are untrained apes that somehow gained access to a pen. This is only the latest absurd episode in DWP’s ongoing deep mistrust of the medical profession, whose knowledge of their own patients is often ignored in favour of a brief assessment by an outside agency. IDS implies it is yes-no question that GPs ask; you’re either well enough to work or signed off indefinitely to leech from the state. This is simply not true. GPs can recommend their patients for differing approaches for remaining in work, be it a phased return or adapted circumstances and they do tend to have the advantage over the DWP’s agency of having actually met their patient before.
I have read enough stories of the callous ineptitude of sanctions and cuts starving the people we are meant to be protecting. A robust welfare system is the sign of a society that cares for those in need. We need to provide accessible, suitable jobs for those who can work and accessible, suitable benefits for those who can’t. That truly would be a gift that keeps giving.
