Time invariance of factor loadings is a standard assumption in the analysis of large factor models. Yet, this assumption may be restrictive unless parameter shifts are mild (i.e., local to zero). In this paper we develop a new testing procedure to detect big breaks in these loadings at either...

We employ a novel identification scheme to quantify the macroeconomic effects of monetary policy shocks in the United States. The identification of the shocks is achieved by exploiting the instabilities in the contemporaneous coefficients of the structural VAR (SVAR) and in the covariance matrix...

This paper assesses the economic value of modeling conditional correlations for mean–variance portfolio optimization. Using sector returns in three major markets we show that the predictability of models describing empirical regularities in correlations such as time-variation, asymmetry and...

Between 2013 and 2014, following the recession triggered by the sovereign debt crisis, euro-area inflation decreased sharply. Although a fall in the inflation rate was to be expected, given the severity of the recession, professional forecasters failed to anticipate it. A possible explanation...

We exploit the new historical national accounts data for Italy over the period 1861-2010, built by Banca d'Italia and Istat, with the collaboration of the University of Rome "Tor Vergata". In the first part of the paper, a thorough study of the new data's statistical properties is presented...

This paper examines the causality linkages between economic growth, renewable energy consumption, CO2 emissions and domestic investment in Tunisia between 1971 and 2010. Using the ARDL bounds testing approach to cointegration, long-run relationships between the variables are identified. On the...

This paper investigated whether the effect of the shale gas revolution on the U.S. gas market is still a domestic phenomenon or this revolution is influencing the global natural gas market. We used the Bai-Perron test to identify the break date related to the shale gas revolution and tested the...

This paper examines the causality linkages between economic growth, renewable energy consumption, CO2 emissions and domestic investment in Tunisia between 1971 and 2010. Using the ARDL bounds testing approach to cointegration, long-run relationships between the variables are identified. The...

With the introduction of a destination-based VAT in all but eight states starting April 2005, there is need for a good baseline indicator of tax buoyancies in states in the period immediately preceding. This to provide such a base, with buoyancies estimated over a 23-year span starting in...

While the global economic recovery continues, it remains uneven and subject to downside risks. Yet,to the extent that these linger, they could undermine growth further and foster larger macroeconomic imbalances.In fact,one unwanted characteristics that most Sub-saharan African economies share,...
