Policy issues 83<br />
Relative to the US, the policy mix in the Eurozone was much less effective<br />
in cushioning the impact of the financial crisis while at the same time putting<br />
economies on a sustainable path of deleveraging. Indeed, the double whammy of<br />
procyclical fiscal austerity and a credit crunch has made the deleveraging process<br />
much more costly. In turn, this has exacerbated the slowdown in nominal GDP,<br />
by both undermining the potential rate of growth and favouring excessive<br />
disinflationary pressures. Although a number of institutional constraints in<br />
the design and functioning of the monetary union have contributed to this<br />
unfortunate policy mix, it is important for the Eurozone that policymakers now<br />
deal with both the subdued economy and excessive leverage with force and in a<br />
timely manner, avoiding the mistakes of the past.<br />
A credible result of the asset quality review is important, and so is renewed<br />
policy action by the ECB. The June 2014 announcement of new measures to<br />
repair the broken transmission mechanism and stimulate lending to small and<br />
medium enterprises is a welcome signal of its commitment to avoid a persistent<br />
undershooting of its inflation target. We advocate that the ECB engage in sizeable<br />
quantitative easing as soon as possible. A forceful intervention with outright<br />
purchases of sovereign bonds – as well as private securities – is the correct tool<br />
for dealing with excessive downward pressure on inflation and fulfils the ECB<br />
mandate of price stability while helping the stabilisation of the debt and easing<br />
credit conditions. Further procrastination in implementing these by now urgent<br />
policy measures would risk, in the medium term, the resurgence of pressures<br />
on the sustainability of the Eurozone itself. However, monetary policy is not<br />
the appropriate tool to solve debt sustainability and debt overhang problems for<br />
which, in extreme cases, some form of debt restructuring should be considered<br />
together with adequate structural policies. 28<br />
Issue 2. Fiscal policy<br />
In this report we have claimed that, in the US, the aggressive fiscal response in<br />
the aftermath of the crisis helped households to deleverage without an excessive<br />
fall in consumption. Indeed, the literature has pointed to a large fiscal multiplier<br />
at the zero lower bound (for recent evidence, see Christiano et al., 2014). The<br />
cost of this policy, however, has been rapidly expanding public debt. At the<br />
beginning of 2011, government consumption started declining again and the<br />
deficit-to-GDP ratio has more than halved since 2009. An important policy<br />
question is whether fiscal policy is now too restrictive in the US and is possibly a<br />
contributory factor to the weakness of the recovery. The answer to this question<br />
depends on the estimate of the size of the multiplier. Although such estimates<br />
are highly uncertain, it is likely that with the interest rate departing from the<br />
zero lower bound and the end of the deleveraging process, the multiplier is lower<br />
28 In relation to the private sector, efficient bankruptcy and insolvency arrangements can facilitate the<br />
restructuring of household, corporate and bank debt. In relation to sovereign debt, CIEPR (2013)<br />
provides an overview of proposals to improve sovereign debt restructuring mechanisms, while Paris<br />
and Wyplosz (2014) outline a potential role for the ECB in reducing the burden of Eurozone sovereign<br />
debt.
