What is the paper about? Expansionary fiscal consolidation (EFC) hypothesis
Controversy between AAP and IMF studies AAP: fiscal consolidation (CAPB measure) may be expansionary if
implemented by cutting government spending IMF study: effects are biased; new estimates (action based using
historical records as in Romer and Romer, 2010) suggest that fiscal consolidation has contractionary effects
Perotti (2011): IMF criticism is correct in principle, but has its own limitations
Case studies of fiscal consolidation episodes Denmark, Ireland, Finland and Sweden provides some evidence on
the existence of EFC Though unlikely in the current environment

What is the paper about? General problems in identifying the impact of fiscal
shocks on output Countercyclical response problem: policy maker
might implement systematic, countercyclical changes to policy parameters (e.g. tax rates) to react to the current states of the economy
Imperfect cyclical adjustment: surplus reacts automatically to asset prices, because their effects on tax revenues (standard CAPB do not correct for that)
IMF: AAP study using CAPB is subject to both, which can explain the differences between the two studies
Perotti (2011): IMF study might also be subject to the countercyclical response problem, so coefficients might be biased towards zero.

IMF vs. AAP vs. Perotti (2011) Perotti (2011) : IMF and AAP agree that on average
fiscal consolidations are associated with a recession in the short-run. Main issue of contention: spending based consolidation
IMF (contractionary) vs. AAP (expansionary) Arguments used by the IMF study to explain
differences are incorrect Both effects create a positive bias between revenue
based increases in surplus and GDP growth. But the AAP estimates are actually negative, so removing
this effect would reinforce the main finding of AAP. Censoring bias of the IMF approach, as only positive
values of fiscal shocks are recorded Omitting the countercyclical response

Comments: CAPB vs. Action Based approach Do IMF and AAP agree that, on average, fiscal consolidations are associated with the recessions in the short-run?

Comments: censoring bias To test whether these effects matter, set all
negative changes also in the CAPB-to-GDP ratio to zero
![Page 7: Discussion of “The Austerity Myth”- Gain without Pain by Roberto Perotti* Roland Straub](https://reader035.vdocuments.mx/reader035/viewer/2022062814/568167b5550346895ddd053d/html5/thumbnails/7.jpg)
Comments: omitting the countercyclical response
Quote: “While omitting the countercyclical response of fiscal policy has an obvious motivation for the purpose of estimating the multiplier of fiscal policy actions, it can provide the wrong picture of the actual fiscal policy stance when trying to gather the size of fiscal consolidations”
True motivation is indeed difficult to identify, even in an action based approach.
Tough call…

Case studies: main findings Discretionary fiscal consolidations are often
smaller than estimated in the past All stabilization were associated with
expansions in GDP. Except in Denmark, all stabilization were driven by
exports Denmark: internal devaluation using
nominal exchange rate as a nominal anchor. Wage restraints and income policies as a
substitute of a devaluation The expansion was followed by a slump that
lasted for several years

Case studies: main findings
Quote from Perotti ( 2011), page 5:“Some of the conditions made these
consolidationsexpansionary - (i) a decline in interest rates
from very high levels, (ii) wage moderation relative to
other countries, perhaps supported by income
policies- seem not to be applicable in the present
circumstances. “

The Question of the Day
Quote: “To be sure fiscal multipliers depend on the state of the economy and can change overtime. But can they change sign in a little over a year? Does any model exist to show that 18 months ago it made sense for the United Kingdom to expand fiscal policy, while now it makes sense to implement the recently announced 25 percent nearly across-the-board budget cuts.”

Expansionary Fiscal Contraction
(i) Are we in a low interest rate environment?
(ii) Is wage moderation relative to other countries, perhaps supported by income
policies, applicable in the present circumstances?

Impact of fiscal consolidation is state dependent
Expansionary fiscal contraction if Fiscal strain is
pervasive and And monetary
policy is constrained at the ZLB

Risk Premium in an Open Economy
Similar results hold in an open-economy version of the model with monetary union

Conclusion
Very interesting paper. I agree with most of the conclusions. But, I would argue that there is potentially
a case for having expansionary effects of fiscal contractions even (or especially) in the current environment.

Fiscal Limits and Monetary Policy
Leeper and Walker (2011) Unresolved fiscal stress raises the possibility
that the economies hit fiscal limits Monetary Policy might loose its ability to control
inflation and influence the economy in a usual ways.
