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 study reconsiders the common unit root/co-integration approach to test for the Fisher effect for the economies of the G7 countries. We first show that nominal interest and inflation rates are better represented as I(0) variables. Later, we use the Bai–Perron procedure to show the...

In this paper, we obtain a statistic that is useful for the analysis of the integration order of a variable which exhibits two changes in its mean. Our work begins by showing that the most commonly used unit root tests behave asymptotically in a correct manner for double changing mean variables....
