INTRODUCTION
Following the economic crisis started in 2008 in the US, the problem of whether fiscal contractions
have a negative effect on output has turned to be much more relevant than in the past.
The immediate response to economic downturn was the approval of fiscal stimulus packages and
the injection of money via reduction in interest rates. Shome (2012, p. 49) points out that “Focus
turned to fiscal stimuli through tax reductions and mainly current expenditure enhancements. But
the size of the fiscal multiplier was not known either. Hence the dilemma as to whether the same
fiscal stimuli would work to the same extent across countries.”
In most advanced countries, debt-to-GDP ratios have rapidly grown because of bank rescuing and
of an increasing demand for welfare support (especially unemployment income) combined with
falling revenues due to declining employment rates. The intervention by governments and Central
Banks to secure private savings through the recapitalization of private banks that were involved -
directly or indirectly - in the mortgage crisis has caused a dramatic increase in public debt. This was
more rapid in economies hardest hit by the financial crisis (US, UK, Iceland, Ireland and Spain).
Other countries, such as Japan and Italy, already had high debt-to-GDP ratios. Table 1 shows that,
also in Germany, government gross debt as a percentage of GDP increased.

However, the fact the crisis started from private sector encourages some scholars – see Blyth (2013)
– to claim that it was not really a sovereign debt crisis.
However, after 2010, the problem of increasing debt-to-GDP ratio has become more relevant
because of the negative reaction of stock market and rating agencies. Shome (2012) argues that
policies were refocused on fiscal consolidation, but there was not unanimous consensus about this
4
switch. One view was that fiscal loosening should continue; another view was that fiscal policy
should be tightened; a third view was to adopt an intermediate path.
Some economic areas, such as the European Union, have chosen an austerity path in order to secure
public budgets of member States. This has implied the imposition of sharp spending cuts or tax
increases to those countries who had an excessive Debt/GDP ratio (especially the Southern
European countries) and blocking fiscal stimulus programs in those economies that did not suffer
from this problem (Germany, the Netherlands). Recovery in the EU has been very slow – with some
exceptions - making effectiveness of austerity policies a key issue in the electoral campaign for the
European elections in 2014. Political debate has recently have been focused on the flexibility of
budgetary parameters signed in the Maastricht Treaty and strengthened by means of the inscription
of balanced budget rule in Member States’ constitutions. In his speech for the beginning of the
Italian Presidency of European Union, Italian Prime Minister Matteo Renzi has stressed the
importance of investment for growth in combination with the compliance of balanced budgets.
Reuters (2014) publishes the answer by Manfred Weber, German head of European People’s Party,
who claimed “more flexibility would be the wrong way forward” and invoked the compliance
with budgetary rules. In an interview published on the Italian newspaper Il Fatto Quotidiano in
August 2014, Tabellini contends that European budgetary rules are counterproductive since the 3%
ceiling in the deficit-to-GDP ratio is too demanding for Southern Europe economies. He suggests a
more aggressive deficit financed tax-based fiscal stimulus programme supported by extraordinary
monetary tools as, for example, quantitative easing.
In any case, we expect the issue of flexibility to be crucial in the political debate of European
institutions, with an increasing confrontation between supporters of fiscal discipline – led by
Germany and the Netherlands – and countries that require a switch towards investment and less
rigid budgetary rules.
Conversely, the United States have chosen a different path, mainly composed by more or less
consistent fiscal stimulus packages and supported by an expansionary monetary policy, which
included direct acquisition of public debt assets. These actions have raised many critiques about the
use of debt to exit from a crisis provoked by debt. According to some scholars and conservative
politicians, public intervention is likely to cause an important growth of the cost of financing, with
an increase of the interest rate on public bonds. In April 2010, in his speech at the National
Commission on Fiscal Responsibility and Reform, FED governor Bernanke pointed out that “The
ultimate goal of the Commission's efforts should be to put us on a path to fiscal sustainability. One
widely accepted criterion for sustainability is that the ratio of federal debt held by the public to
national income remain at least stable (or perhaps even decline) in the longer term.” In July 2010,

Mort Zuckerman warned on the Financial Times “The president (Obama) has lost the confidence of
employers, whose worries over taxes and the increased costs of new regulation are holding back
investment and growth.”
Nevertheless, like Figure 1 shows, the cost of long-term financing for US Federal Government has
not increased, actually it decreased by 1%, suggesting that the threat of rising interest rates on
public debt bonds was not grounded at that time.

Krugman (2012) gauges the emphasis on the negative role played by government intervention in the
economy an ideological claim, since academic debate has not provided any incontrovertible
evidence supporting one thesis or the other.
In his view, Keynesian theory is considered dangerous by conservative circles that consider it the
first step of an escalation bringing the United States – and the world – under a socialist power.
Because of that, they would have instrumentally used economic arguments in favour of a less
expansionary fiscal policy in order to support their ideological believes and to safe economic
interests of their traditional political supporters. Kalecki in 1943 wrote that capitalists have a sort of
veto power against each public intervention since, in a laissez-faire capitalist system, confidence
level is a key feature. If it decreases, so private investments do, with a bad effect on production and
employment. However, “once the government learns the trick of increasing employment by its own
purchases, this powerful controlling device loses its effectiveness”.
Blyth (2013) argues that introducing in the presentation of macroeconomic measures some kind of
morality play between “good austerity” and “bad spending” may lead into a period of self-defeating

budget cuts. Krugman (2012) also criticizes this aspect, saying that it is not necessary to atone
suffering from draconian cuts.
A growing literature analyses the relationship between fiscal consolidation and output, developing
two main paths.
1. A “Keynesian” path, claiming that contractionary fiscal policy during crisis has a negative
effect on aggregate consumption that cannot be offset by private investment growth.
2. A non-Keynesian path, claiming that fiscal consolidation in some cases has no negative
effect and can even foster growth in the short run as well.
A key feature is the role of expectations, which can influence the behaviour of the actors: the main
question is whether they can offset the effect of a lower government spending or not.
While both theoretical models are valid and have some explanatory power, the empirical evidence,
since financial crisis, suggests that there is a positive correlation between the size of a reduction in
government deficits and a change in GDP. The greater the reduction in fiscal deficit, the worse the
contraction in the economy. (Hall, 2012)
Moreover, if until 2013 economists and politicians thought, consistently with an important paper by
Reinhart and Rogoff, that a debt-to-GDP ratio above 90% can significantly undermine growth,
recent studies have shown that this threshold is not so rigid. This debate is much more relevant
since it has a direct impact on real policies applied by the biggest economies in the world, mainly
the EU, the US and emerging countries.
This dissertation aims to identify economic effects of fiscal consolidations of which Amo-Yartey et
al. (2012, p. 16) provide a general definition: “the standard approach is to relate fiscal
consolidation to a specific improvement in the cyclically adjusted primary balance (CAPB) as a
percentage of potential GDP over a specific period.” Yet, in the literature, the identification of
fiscal consolidation varies and partially reflects different study objectives.
The thesis is divided in two part: the first one provides a review of relevant literature focusing on
the factors that originate Keynesian effects and non-Keynesian effects and classifying the channels
that work during a fiscal consolidation, defined as an exogenous policy shock. Requiring the fiscal
shock to be orthogonal to business cycle shocks and monetary policy shocks is crucial in order to
rule out the possibility that a spending cut or tax hike depend on the economic cycle (i.e. on GDP
fluctuations and/or changes in monetary supply).

The second part is devoted to a deeper analysis of Alesina, Giavazzi, Favero (2012), and of the
more recent paper in which the authors fixed some mistakes. The focus will be on economic
growth, testing whether fiscal episodes listed in the paper started in expansionary periods or during
recessions. Then, we will provide an estimation of the impact of fiscal shocks in good and bad times
and of the role of previous economic performance.
