AbstractForecasting the economic policy uncertainty in Europe is of paramount importance given the ongoing sovereign debt crisis. This paper evaluates monthly economic policy uncertainty index forecasts and examines whether ultra‐high frequency information from asset market volatilities and global economic uncertainty can improve the forecasts relatively to the no‐change forecast. The results show that the global economic policy uncertainty provides the highest predictive gains, followed by the European and US stock market realized volatilities. In addition, the European stock market implied volatility index is shown to be an important predictor of the economic policy uncertainty.

In this study we examine the dynamic interrelationship in the output-energy- environment nexus by applying panel vector autoregression (PVAR) and impulse response function analyses to data on energy consumption (and its subcomponents), carbon dioxide emissions and real GDP in 106 countries classified by different income groups over the period 1971{2011. Our results reveal that the effects of the various types of energy consumption on economic growth and emissions are heterogeneous on the various groups of countries. Moreover, causality between total economic growth and energy consumption is bidirectional, thus making a case for the feed- back hypothesis. However, we cannot report any statistically significant evidence that renewable energy consumption, in particular, is conducive to economic growth, a fact that weakens the argument that renewable energy consumption is able to promote growth in a more efficient and environmentally sustainable way. Finally, in analysing the case for an inverted U-shaped EKC, we find that the continued process of growth aggravates the greenhouse gas emissions phenomenon. In this regard, we cannot provide any evidence that developed countries may actually grow-out of environmental pollution. In the light of these findings, the efficacy of recent government policies in various countries to promote renewable energy consumption as a means for sustainable growth is questioned. Put differently, there seems to be an ethical dilemma, between high economic growth rates and unsustainable environment and low or zero economic growth and environmental sustainability.

We examine business cycle spillovers in the European Union over the period 1977–2014. The results of our analysis reveal that: (i) The total spillover indices are of high magnitude and very responsive to extreme economic events. (ii) The direction and magnitude of spillovers among group members (i.e. Eurozone core, Eurozone periphery, new Euro Area countries and non-European Monetary Union countries) is changing overtime. (iii) The widening of the European debt crisis can be explained by business cycle shocks in the whole Eurozone periphery. Thus, appropriate macroprudential stabilization policies aiming to steer peripheral economies towards growth should be formulated.

AbstractThis article investigates the time‐varying correlation between the EU12‐wide business cycle and the initial EU12 member‐countries based on Scalar‐BEKK and multivariate Riskmetrics model frameworks for the period 1980–2012. The paper provides evidence that changes in the business cycle synchronization correspond to major economic events that have taken place at a European level. In the main, business cycle synchronization until 2007 had moved in a direction positive for the operation of a single currency, suggesting that the common monetary policy was less costly in terms of lost flexibility at the national level. However, as a result of the Great Recession of 2007 and the subsequent Eurozone Crisis, a number of periphery countries, most notably Greece, have experienced desynchronization of their business cycles with the EU12‐wide cycle. Nevertheless, for most countries, any questions regarding the optimality and sustainability of the common currency area in Europe should not be attributed to a lack of cyclical synchronization.
