This paper presents a theoretical approach to solve the main problems faced to explain the relationship between aggregate economic growth and the urban structure. The most significant conclusion reached is that there is a theoretical relationship between aggregate economic growth and urban...

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

This paper analyses the time series properties of the unemployment rates of the 50 US States, as well as the global rate of the USA. Our results, based on the use of ADF-type tests, show that the inclusion of some breaks is vital in order to reduce the persistence on these rates. Thus, we can...

This paper shows that the acceptance of the Zipf's Law may sometimes be the result of a spurious artifact. By way of some Monte Carlo exercises we provide evidence in favour of the fact that the Zipf's law can be spuriously accepted when the variable being studied is generated by a random...

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 addresses tests for structural change in a weakly dependent time series regression. The cases of full structural change and partial structural change are considered. Heteroskedasticity-autocorrelation (HAC) robust Wald tests based on nonparametric covariance matrix estimators are...

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 existence...
