But, as the European economy risks falling into recession, many
observers are asking whether “austerity” could be self-defeating. Could a
reduction in government expenditure (or an increase in taxes) lead to
such a sharp decline in economic activity that revenues fall and the
fiscal position actually deteriorates further?
This is highly unlikely, given the way our economies work. Moreover,
if it were true, it would follow that tax cuts would reduce budget
deficits, because faster economic growth would generate higher revenues,
even at lower tax rates. This proposition has been tested several times
in the US, where tax cuts were invariably followed by higher deficits.
In Europe, the concern today is instead with the debt/GDP ratio. The
worry here is that the GDP drop resulting from “austerity” might be so
large that the debt ratio increases. This matters, because investors
often use the debt ratio as an indicator of financial sustainability.
Thus, a lower deficit might actually heighten tensions in financial
markets.
However, a lower deficit must lead over time to a lower debt
ratio, even if this ratio worsens in the short run. After all, most
models used to assess the economic impact of fiscal policy imply that a
cut in expenditure, for example, lowers demand in the short run, but
that the economy recovers after a while to its previous level. So, in
the long run, fiscal policy has no lasting impact (or only a very small
one) on output. This implies that whatever short-run negative impact
lower demand may have on the debt ratio should be offset later (in the
medium to long run) by the rebound in demand that brings the economy
back to its previous output level.
Moreover, even assuming that the impact of a permanent cut in public
expenditure on demand and output is also permanent, the GDP reduction
remains a one-off phenomenon, whereas the lower deficit continues to
have a positive impact on the debt level year after year.
Notice that this conclusion was reached without any recourse to what
Paul Krugman and others have derided as the “confidence fairy.” In the
US, it might indeed be unreasonable to expect that a lower deficit
translates into a lower risk premium – for the simple reason that the US
government pays already ultra-low interest rates.
But, even without any confidence effects, the bipartisan
Congressional Budget Office has concluded that, while cutting the US
deficit does lower demand, it still leads reliably to a lower debt
ratio. This should be all the more true for eurozone countries, like
Italy or Spain, that are now paying risk premia in excess of 3-4%. For
these countries, the confidence fairy has become a monster.
The decisive question then becomes: What matters more, the impact of
deficit cutting on the debt/GDP ratio in the short run or in the long
run?
Prospective buyers of Italian ten-year bonds should look at the
longer-term impact of deficit cutting on the debt level, which is pretty
certain to be positive. Of course, some market participants might not
be rational, demanding a higher risk premium following a short-term
deterioration of the debt ratio. But those concentrating on the short
term risk losing money, because the risk premium will eventually decline
when the debt ratio turns around.
Abandoning austerity out of fear that financial markets might be
short-sighted would only postpone the day of reckoning, because debt
ratios would increase in the long run. Moreover, it is highly unlikely
that Italy, for example, would pay a lower risk premium if it ran larger
deficits.
It would be dangerous for the eurozone’s highly indebted countries to
abandon austerity now. Any country that enters a period of heightened
risk aversion with a large debt overhang faces only bad choices.
Implementing credible austerity plans constitutes the lesser evil, even
if this aggravates the cyclical downturn in the short run.
