Dividing Lines: The economy

Continuing his series on the major policy divisions in politics, Rafael Behr tackles the economy.

What’s the issue?
This is the big one. When the coalition was formed it claimed its governing purpose was to rescue Britain from an economic emergency. The remedy devised by George Osborne was an immediate course of spending cuts to reduce the Budget deficit and limit the rise in public debt as a proportion of gross domestic product. The theory was that a shock-and-awe display of fiscal discipline would reassure international investors that Britain was a “safe haven” from global turbulence. Cutting the public sector is also meant to release growth potential in the private sector, which was thought to have been “crowded out” by state expansion under Labour.

Is it working?
No. The economy didn’t grow at all last year. It is 3.3 per cent smaller than at its boom-time peak. Osborne is on course to fail his self-imposed tests of credibility – eliminating the “structural” deficit (the part of government overspend that doesn’t vanish automatically when the economy is operating at full capacity) and reducing public debt as a proportion of GDP by the end of this parliament.

What went wrong?
The government says its inheritance from Labour was worse than previously thought and that the eurozone crisis has blown recovery off course. Labour says the rush to austerity has drained demand out of the economy; when companies and households were too indebted or too frightened to spend, the government should have stepped in to stimulate activity – hitting the gas instead of slamming on the brakes.

So, Labour would turn on the money taps again?
Economically, that is the logic of Ed Balls’s position but politically he is in a bind. Lots of people are persuaded that an underlying cause of the crisis was “Gordon Brown spending all the money”. Whenever Balls attempts to make his macroeconomic argument, he ends up trying to rehabilitate the reputation of a period in Labour’s record that even many on his own side think is better off left for dead. Besides, by the time of the next election, the public finances will be in such a woeful state that there will be no spare capacity to increase spending. The campaign will be about who cuts what and with what end in mind.

Couldn’t the government borrow to spend?
Yes. And it is quietly doing just that, because there is no growth. There is a case for saying that the low long-term interest rates available now make it a good time to borrow for investment in such things as housing and transport that would create jobs and strengthen our economic capacity.

Even Osborne has discreetly conceded the point that cuts alone won’t kick-start growth. In his Autumn Statement last year, the Chancellor said he would find £5bn for infrastructure investment, but the money has to be carved out by making cuts to other budgets. He has painted himself into a corner, insisting any dilution of austerity would be a disaster and portraying borrowing as inherently wicked. So, to be true to their own political script, the Tories have to pretend to be less reliant on borrowing than they are. It is higher now than at the last election, and rising. David Cameron recently claimed that the government is “paying down the debt” but by any measure it simply isn’t.

That’s a bit sneaky, isn’t it?
Very. The question is how long they’ll get away with it. There is a strong expectation that the credit-rating agencies will downgrade the UK this year, torpedoing Osborne’s “safe haven” claim. Balls’s problem is that he struggles to call out the Tories for relying on debt: his core macroeconomic analysis demands the same fiscal remedy. Intellectually, his position can be made coherent but it relies on a distinction between “good” Labour borrowing – premeditated to spur growth – and “bad” Tory borrowing – accidental, driven by a failed austerity plan. The difference is not immediately obvious to many voters.

Besides, no one doubts that the Tories at least want to limit public spending, while Labour risks looking like it wants to duck that challenge altogether. In order to reassure swing voters that it is a careful steward of taxpayers’ money, the opposition could end up accepting spending restraints that don’t permit the kind of stimulus that has been central to its macroeconomic prescription.

So Labour thinks we should be borrowing more but doesn’t feel comfortable admitting it, and the Tories are borrowing more but pretend they aren’t?
Pretty much. A vital difference is that many Conservatives think the government isn’t cutting budgets deeply enough. The Tory hawks think the way out of the growth impasse is on the “supply side”– cutting back on regulations and employment rights in the belief that excessive bureaucracy is stifling enterprise. Labour sees that as a sign the Tories are using the financial crisis as a pretext to pursue an old agenda of shrinking the role of government in public life. It doesn’t, Labour says, tackle the underlying problem of inadequate demand.

What do the Lib Dems think?
Their instincts are with Labour. Nick Clegg has conceded that infrastructure spending was cut too hard in the coalition’s early days. Yet within the broad outline of austerity the Lib Dems are lashed to Osborne’s mast; they sign off on his budgets.

That doesn’t sound very comfortable.
In this debate, no one is.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
