    What do we know about the effects of austerity?

    This revision December 2017


        The literature on fiscal multipliers is far from having reached an agreed upon conclusion about their size and how they might be state contingent.  There is so  much debate about this issue, that Eric Leeper (2010) defined this literature as "alchemy". One result, however, seems very robust: in OECD economies fiscal consolidations (austerity) based upon expenditure cuts are much less costly than those performed on the tax side. This result was originally shown by an early literature which studied episodes of austerity before the Great Recession. Alesina and Ardagna (2010) summarized and extended these results, which were then confirmed in IMF (2010) and Guajardo et (2014) using a methodology based upon the narrative method pioneered by Romer and Romer (2010). The purpose of this paper is twofold. First, we review more recent evidence based upon an extension of the narrative method which considers multi-year fiscal plans rather than year-by-year shifts in fiscal variables, like in Romer and Romer (2010) and Guajardo et al(2014). We shall also document cases of "expansionary austerity", namely episodes in which even large reductions of government spending were associated on impact with increases in GDP growth  -- a possibility first recorded by Giavazzi and Pagano (1990). Second, we illustrate alternative theoretical explanations for our findings about spending- versus tax-based consolidations.

    Nudging financial and demographic literacy: experimental evidence from an Italian Trade Union Pension Fund

    This Revision April 2017 

    Abstract: In this article, we present and test experimentally a low-cost, Internet-based, financial and demographic literacy program that we designed for implementation with the largest industrial pension fund in Italy. The program, Finlife (Financial Education and Planning for a Long Life) included 1) an instructional video and materials provided through the Internet; 2) an experimental design that explicitly allows to evaluate the impact of the instructional video and materials on financial and demographic literacy, as well as on short-term behavioral changes; 3) a follow-up to assess the stability of some of the experimental outcomes. Finlife was designed to be a low-cost and scalable approach to increase financial and demographic literacy, consistently with a ‘nudge’ philosophy. We show that Finlife delivered a substantially and statistically significant increase in financial and demographic literacy, as well as a push towards behaviors involving seeking more information on financial markets and choices related to financial planning.

    The effect of Fiscal Consolidations: Theory and Evidence

    This revision April 2017  

    AbstractAbstract We investigate the macroeconomic effects of fiscal consolidations based upon government spending cuts, transfers cuts and tax hikes. We extend a narrative dataset of fiscal consolidations, finding details on over 3500 measures. Government spending and transfer cuts are much less harmful than tax hikes. Standard New Keynesian models match our results when fiscal shocks are persistent. Wealth effects on aggregate demand mitigates the impact of a persistent spending cut. Static distortions caused by persistent tax hikes cause larger shifts in aggregate supply under sticky prices. This channel explains different sizes of multipliers found in fiscal stimuli compared to consolidation plans.

    Implications of Returns Predictability Across Horizon for Asset Pricing Models
    Favero CA, F.Ortu, A.Tamoni and H.Yang

    This Version March 2017 
    We use the evidence on predictability of returns at different horizons to discriminate among competing asset pricing models. Specifically, we employ predictors-based variance bounds, i.e. bounds on the variance of the Stochastic Discount Factors (SDFs) that price a given set of returns conditional on the information contained in a vector of return predictors. We show that return predictability delivers variance bounds that are much tighter than the classical, unconditional Hansen and Jagannathan (1991) bounds. We use the predictors-based bounds to discriminate among three leading classes of asset pricing models: rare disasters, long-run risks and external habit. We find that the rare disasters model of Nakamura, Steinsson, Barro, and Urs´ua (2013) is the best performer since it satisfies rather comfortably the predictors-based bounds at all horizons. As for long-run risks, while the classical version of Bansal and Yaron (2004) is the model most challenged by the introduction of conditioning information since it struggles to meet the bounds at all horizons, the more general version of Schorfheide, Song, and Yaron (2016), which accounts for multiple volatility components, satisfies the 1- and 5-year bounds as long as the set of test assets includes only equities and T-Bills. The Campbell and Cochrane (1999) habit model lies somehow in the middle: it performs quite well at our longest 5-year horizon while it struggles at the 1-year horizon. Finally, when the set of test assets is augmented with Treasury Bonds, the only model that is able to satisfy the predictors-based bounds is the rare disasters model.
