- PublicationGreat Recession, Slow Recovery and Muted Fiscal Policies in the US(University College Dublin. School of Economics, 2016-03)
; ; This paper reconsiders the role of macroeconomic shocks and policies in determining the Great Recession and the subsequent recovery in the US. The Great Recession was mainly caused by a large demand shock and by the ZLB on the interest rate policy. In contrast with previous findings, the subsequent jobless recovery is explained by the ZLB effect. We estimate a fraction of non-Ricardian households which is close to 50%, and obtain comparatively large fiscal multipliers. However we cannot detect a significant contribution of fiscal policies in stabilizing the US economy. For instance, the 2007-2009 large increase in expenditure-to-GDP ratios was apparently determined by the adverse non-policy shocks that caused the recession.468 - PublicationBayesian forecasting with small and medium scale factor-augmented vector autoregressive DSGE modelsAdvanced Bayesian methods are employed in estimating dynamic stochastic general equilibrium (DSGE) models. Although policymakers and practitioners are particularly interested in DSGE models, these are typically too stylized to be taken directly to the data and often yield weak prediction results. Hybrid models can deal with some of the DSGE model misspecifications. Major advances in Bayesian estimation methodology could allow these models to outperform well-known time series models and effectively deal with more complex real-world problems as richer sources of data become available. A comparative evaluation of the out-of-sample predictive performance of many different specifications of estimated DSGE models and various classes of VAR models is performed, using datasets from the US economy. Simple and hybrid DSGE models are implemented, such as DSGE–VAR and Factor Augmented DSGEs and tested against standard, Bayesian and Factor Augmented VARs. Moreover, small scale models including the real gross domestic product, the harmonized consumer price index and the nominal short-term federal funds interest rate, are comparatively assessed against medium scale models featuring additionally sticky nominal prices, wage contracts, habit formation, variable capital utilization and investment adjustment costs. The investigated period spans 1960:Q4–2010:Q4 and forecasts are produced for the out-of-sample testing period 1997:Q1–2010:Q4. This comparative validation can be useful to monetary policy analysis and macro-forecasting with the use of advanced Bayesian methods.

; ; This paper examines whether the presence of parameter instabilities in dynamic stochastic general equilibrium (DSGE) models affects their forecasting performance. We apply this analysis to medium-scale DSGE models with and without financial frictions for the US economy. Over the forecast period 2001-2013, the models augmented with financial frictions lead to an improvement in forecasts for inflation and the short term interest rate, while for GDP growth rate the performance depends on the horizon/period. We interpret this finding taking into account parameters instabilities. Fluctuation test shows that models with financial frictions outperform in forecasting inflation but not the GDP growth rate.641 - PublicationIn search of the Euro area fiscal stance(University College Dublin. School of Economics, 2016-08)
; ; This paper investigates the role of fiscal policies over the aggregate EMU business cycle. Previous studies, based on the assumption of non-separability between public and private consumptions, obtain a large public consumption multiplier, a small fraction of non-Ricardian households and, consequently, a relatively small multiplier for public transfers. We provide motivations for assuming separability and, on these grounds, we estimate a relatively large share of non-Ricardian households. As a result, we obtain that both multipliers are large. We also find that, in spite of their potentially strong effects, fiscal policies were substantially muted during the EMU years. This result is confirmed even for the post 2007 period. In fact fiscal policies did not complement the monetary policy stimulus in response to the financial crisis. Further, we cannot detect any substantial aggregate effect of austerity measures. Finally, the post-2007 surge in expenditure-to-GDP ratios was apparently determined by non-policy shocks that reduced output growth.424
