CAMBRIDGE
– Like most people who create an “ism,” John Maynard Keynes quickly
found his followers running ahead of him. “You are more Keynesian than I
am,” he once told a young American economist. Now it is the turn of his
biographer, Robert Skidelsky, to become distinctly more Keynesian than
Keynes.
Keynes
was not averse to changing his mind. But, as far I am aware, he did not
change his predictions after the fact. This does not seem to be the
case for Skidelsky.
In November 2010, Skidelsky described
British Chancellor of the Exchequer George Osborne as a “menace to the
future of the economy,” whose policies “doomed” the United Kingdom to
“years of interminable recession.” In July 2011, he declared that Osborne was making a “wasteland.”
None
of this happened; the honest thing to do would be to admit that. But,
in pseudo-science, you never acknowledge that a prediction was wrong and
thus that the model might be defective. So now Skidelsky
retrospectively “predicts”
something quite different: “that the start of austerity aborted the
recovery in 2010; that recovery would have come sooner if the
pre-austerity level of public spending had been maintained; [and] that
it was the reduction of austerity in 2012 that enabled the economy to
expand again.” With a flourish, he concludes: “The facts are consistent
with Keynesian theory. Keynesians said austerity would cut output
growth. Output growth fell.”
Yet even Skidelsky admits that he and his fellow Keynesians “cannot prove”
this. Indeed, nothing in Keynes’ theory would allow such simplistic
causal inferences. After all, other forces were at work after 2010 – not
least the eurozone crisis (which some non-Keynesians, including me,
actually predicted before it happened).
Nor
would Keynes have been as confident as Skidelsky that the
counterfactual of continued high deficits would have been without risk
or cost. Historical experience – including in the United Kingdom in the
1970s – tells us that financial markets are not always convinced by
heavily indebted governments that promise to solve their problems by
borrowing even more.
Responding to some early critics of his General Theory,
Keynes showed that he recognized the importance of uncertainty in
economic life, and consequently the difficulty of making predictions.
“The whole object of the accumulation of wealth,” he wrote, “is to
produce results, or potential results, at a comparatively distant, and
sometimes at an indefinitely distant, date.”
But,
Keynes continued, “our knowledge of the future is fluctuating, vague,
and uncertain.” There are simply too many things – from the “prospect of
a European war” to the “price of copper and the interest rate 20 years
hence” – about which “there is no scientific basis on which to form any
calculable probability whatever.”
There
was much that we did not know in 2010. We did not know if the UK’s
banking crisis was over; if its very large fiscal deficit (amounting to
nearly 12% of GDP) was sustainable; or what the interest rate would be
in two years, much less 20. The situation was so grave that no
responsible politician favored the type of policies that Skidelsky
argues should have been adopted.
In
fact, at that point, the only real difference between the approach of
the Labour government’s chancellor of the exchequer, Alistair Darling,
and that of Osborne consisted – as is clear from Darling’s last budget statement
– in the timing of austerity. In March 2010, Darling vowed to reduce
the deficit to 5.2% of GDP by 2013-2014. Under his Conservative
successor, the actual deficit in that year was 5.9%.
Skidelsky argues
that “austerity hit the economy, and by hitting the economy, it
worsened the fiscal balance.” But that presupposes what he cannot prove:
that a larger deficit could have been run without any costs.
All
Skidelsky can offer as evidence to support this supposition is the view
of the bond markets: “Long-term nominal and real interest rates were
already very low before Osborne became chancellor, and they stayed low
afterwards.” But, if it were true that “austerity worsened the fiscal
balance,” the markets should have punished Osborne. They did not.
Likewise, if it was true that higher deficits carried no risks, but brought increased benefits, then the Financial Times would have been full of articles by investment-bank economists saying just that. It was not.
To be sure, I must acknowledge that I erred in one respect, which I am grateful to Skidelsky for pointing out. In May, I wrote that
“at no point after May 2010 did [business confidence] sink back to
where it had been throughout the past two years of Gordon Brown’s
catastrophic premiership.” As Skidelsky rightly pointed out, confidence
recovered from its low point in the first quarter of 2009, and reached a
plateau in the first half of 2010. So I should have written: “At no
point after May 2010 did it sink back to its nadir during Gordon Brown’s
catastrophic premiership.”
But
that does not alter my point that the more Paul Krugman talked about
the “confidence fairy” – a term he coined after Osborne became
Chancellor to ridicule anyone who argued for fiscal restraint – the more
business confidence recovered in the UK. Although confidence fell
somewhat in the first two years under Prime Minister David Cameron, it
never approached the low point of the Brown period, and it later
recovered.
Nowadays,
some economists seem to believe that pointing out a single factual
error (out of more than 20 statements of fact) invalidates an entire
argument. But, while it may cause a flutter on Twitter, that is not the
way serious intellectual debate works.
Similarly,
Skidelsky cannot prove that austerity was responsible for the dip in
confidence. The eurozone crisis is a more likely culprit. After all,
Darling had promised his own version of austerity in March 2010.
Skidelsky
attempts to salvage his and Krugman’s claim that the UK’s economic
performance since 2010 was somehow worse than its performance during the
Great Depression, writing that “real per capita GDP has taken
longer to recover this time around.” But a serious student of the
Depression – which Skidelsky used to be – knows that, compared to the
1920s, the UK had a relatively smooth ride in the 1930s, not least
because abandoning the gold standard in 1931 allowed for monetary-policy
easing. In any case, unemployment was far higher in the 1930s than in
the 2010s. And that is the measure that should matter to Keynesians.
To
muddy the waters, Skidelsky cites work by David Bell and David
Blanchflower on “underemployment.” He also raises the issue of
productivity, referring to research by the Trades Union Congress. But at
no point in this discussion have I made any claims about the quality of
the jobs created in the UK since 2010, or about the productivity of
workers.
As
a general rule, union leaders would rather see their members in “good”
jobs, even if that means unemployment for others. My view is that
employment, even in low-paid or part-time jobs, is better than
unemployment. Were he alive today, I think Keynes would agree.
Nevertheless,
I am glad to see that Skidelsky (unlike Krugman) acknowledges the need
for supply-side reforms “to improve skills, infrastructure, and access
to finance,” and concedes that he and his fellow Keynesians “have been
slow to understand that a government cannot increase the national debt
without limit for a cause in which most people do not believe.” He may
be beginning to see the light.
Given
the way Keynesianism came to be associated with inflationary fiscal and
monetary policies in the 1970s, it is easy to forget what a hawk Keynes
was in his final years. The whole point of his 1940 pamphlet How to Pay for the War
was that higher taxes were needed to avoid the kind of inflation
Britain had experienced during World War I. Toward the end of World War
II, he fretted about the high level of military spending, and was
depressed by the loss of power that came with Britain’s large external
debts.
How
do I know all this? Because I read it in the third volume of
Skidelsky’s masterful biography of Keynes. Perhaps, before firing any
more salvos at a fellow historian, its author should re-read his own
book. It might make him a bit less Keynesian.
