The detection and location of additive outliers in integrated variables has attracted much attention recently because such outliers tend to affect unit root inference among other things. Most of these procedures have been developed for non-seasonal processes. However, the presence of seasonality...

This study investigates changes in the relationship between oil prices and the US economy from a long-term perspective. Although neither of the two series (oil price and GDP growth rates) presents structural breaks in mean, we identify different volatility periods in both of them, separately....

This paper analyses to what extent the Spanish provinces have shown a convergence process since 1980 to nowadays. The application of the Phillips-Sul methodology to the HDI recently developped by IVIE lead us to show that we cannot admit the exitence of a unique convergence process between them....

This paper analyses the impact of oil both price shocks on the GDP and prices in the Spanish economy and its seventeen NUTS-2 regions. The Qu and Perron (2007) and the Bai and Perron (1998, 2003a and 2003b) methods identify different periods across the sample. Evidence in favour of a diminishing...

This paper sets out a comprehensive framework to identify regional business cycles within Spain and analyses their stylised features and the degree of synchronization present among them and the Spanish economy. We show that the regional cycles are quite heterogeneous although they display some...
