In the last years a central issue in economic growth debate has been represented by the convergence problem. Many empirical economists have noticed that per-capita GDPs of poor regions tend to converge to those of the richer ones. This tendency is more evident in the nineties when the...

In the last years a central issue in regional economic growth debate is represented by the convergence problem. Many empirical economists have noticed that per-worker GDP of poor regions tend to converge to those of richer regions. However more recently it has been observed that the economic...

The concept of convergence clubs is analyzed and compared with classical methods for the study of economic [beta]-convergence, which often consider the entire data set as one sample. A technique for the identification of convergence clubs is proposed. The algorithm is based on a modified version...

Il presente lavoro analizza la crescita di lungo periodo nell’area del Medio Oriente e Nord Africa, con l’obiettivo di verificare la presenza e la tipologia della convergenza nella regione durante il periodo 1950-2007. L’evidenza empirica del lavoro mostra che la vasta ed eterogenea area...

A multiple imputation technique is proposed to measure sustainable development using models of structural equations (LISREL) for the treatment of missing data. The reliability of such technique is verified comparing the estimation model with missing data to the estimation model with imputed...

This paper proposes a local stationarity approach in EBLUP estimation with the aim to improve the reliability of relative poverty estimates in small areas. The results of the experimentations, performed in the framework of the European Statistics on Income and Living Conditions survey (EU-SILC),...

In sampling theory the large concentration of the population with respect to most surveyed variables constitutes a problem which is difficult to tackle by means of classical tools. One possible solution is given by cut-off sampling, which explicitly prescribes to discard part of the population;...
