What Osborne won't admit: growth has increased because of slower cuts

The Chancellor's claim that "the pace of fiscal consolidation has not changed" is not supported by any of the available data.

Many others – perhaps Fraser Nelson does it best – have poked fun at the most Panglossian elements of the Chancellor’s speech on Monday. But I’d like here to address the substantive arguments he makes about what the path of the UK economy over recent years says about the impact of fiscal policy on growth.

The Chancellor doesn’t deny that growth has been much weaker than forecast, although it’s worth repeating the scale of this underperformance. In June 2010, the Office of Budget Responsibility predicted that by now the economy would be about 7 per cent larger, driven by a sharp rise in business investment and exports, while the deficit would have fallen by two-thirds. What has actually happened? In fact, GDP has grown at less than a third of that rate, business investment has fallen, and the path of deficit reduction bears no resemblance at all to the original projections (which is, as I'll elaborate below, a good thing).    

But, the Chancellor argues, this underperformance has nothing to do with fiscal policy:

the composition and timing of the slowdown in GDP growth relative to forecast is better explained by external inflation shocks, the eurozone crisis and the ongoing impact of the financial crisis on financial conditions. 

The Chancellor claimed his analysis was supported by many "independent economists" - although, oddly, he failed to mention the IMF, which has been the most prominent independent organisation to argue the contrary. Of course, the IMF and those of us who thought the fiscal consolidation plan was too aggressive never denied that these other factors played a par (and that their reversal will indeed help boost recovery).  As I put it here:

it now seems clear that the negative impact of ‘Plan A’ on growth has been significantly greater than expected, although matters have also been exacerbated by even more damaging policy mistakes in the eurozone, as well as high commodity prices.

Coincidentally, on the same day the Chancellor made his speech, other "independent economists" (Oscar Jorda and Alan Taylor) published a widely reported paper suggesting precisely the opposite (an earlier, non-technical summary is here). They find, as shown in their chart:

Without austerity, UK real output would now be steadily climbing above its 2007 peak, rather than being stuck 2% below. 

And they conclude:

Fiscal contraction prolongs the pain when the state of the economy is weak, much less so when the economy is strong....Keynes is still right, after all: “The boom, not the slump, is the right time for austerity at the Treasury.

However, despite the weight of academic research, the Chancellor goes on to claim that current developments support his interpretation of recent past history:

Proponents of the ‘fiscalist’ story cannot explain why the UK recovery has strengthened rapidly over the last six months. The pace of fiscal consolidation has not changed, government spending cuts have continued as planned, and yet growth has accelerated and many of the leading economic indicators show activity rising faster than at any time since the 1990s.

But this is an obvious sleight of hand.  The claim that "the pace of fiscal consolidation has not changed" is not supported by any of the available data. Here is the OBR’s own chart. As Robert Chote, the OBR’s Chair puts it, "deficit reduction appears to have stalled".

Indeed, the OECD, the government’s favourite of the international forecasting bodies (since, as noted above, the IMF shares my interpretation of the impact of fiscal consolidation on growth) goes even further. According to its calculations, the UK is actually expanding its structural deficit in 2013. In other words, the government is engaging in fiscal stimulus.  Personally I find this implausible - the OBR's estimate is that the structural deficit was broadly flat in 2012-13 - but the data hardly seem consistent with the Chancellor's view.

How did this happen? As I explained earlier this year:

So what's going on? As I noted earlier, most of the deficit reduction has come from cutting public sector net investment (spending on schools, roads, hospitals, etc) roughly in half. Pretty much all the rest came from tax increases (note that the investment cuts and tax increases were both, to a significant extent, policies inherited from the previous government). And we can see when it happened - between 2009-10 and 2011-12.

But these sources of deficit reduction stopped in 2011-12, because the government belatedly realised that cutting investment was a major mistake and that the economic imperative was actually to do precisely the opposite (not that there was much investment left to cut); and it stopped putting up taxes overall. So we can see also what's happened since - with the impact of the weak economy on tax receipts reducing revenues, the deficit has been flat and is projected to stay flat.

So the Chancellor’s argument is simply a non sequitur, supported neither by the research evidence nor the data. 

As I wrote here at the turn of the year, we should give the government credit for not digging us further into a hole by trying to stick to its original plans. Fiscal consolidation has slowed, at least for the time being, and as a consequence it is playing a considerably smaller role in driving economic developments than it did two years ago. Meanwhile, the eurozone and global environment is, at least at present, considerably more favourable. Poor policy and bad luck has delayed recovery, relative to NIESR's original forecasts and everyone else's, but has not removed the ability of the UK economy to generate growth. 

So it is perfectly reasonable to ask economic forecasters (including both the OBR and us at NIESR) why we appear so far to have underpredicted the strength of the current upturn. But claiming that this improvement vindicates the earlier damaging mistake the government made by going for front-loaded fiscal consolidation in 2010 just doesn’t make any economic sense.

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.
