In this paper we present a general result concerning the convergence to stochastic integrals with non-linear integrands. The key finding represents a generalization of Chan and Wei's (1988) Theorem 2.4 and that of Ibragimov and Phillips' (2004) Theorem 8.2. This result is necessary for analysing...

This paper highlights a problem in using the first-difference GMM panel data estimator cross-country growth regressions. When the time series are persistent, the first-differenced GMM estimator can be poorly behaved, since lagged levels of the series provide only weak instruments for subsequent...

This paper examines the adequacy of the augmented Solow model for explaining international variation in the standard of living and growth rates. Robust estimation and measurement error diagnostics are used to assess the model in a variety of dimensions. The main findings are that the speed of...

The article aims to present and discuss estimates of levels of human and social capital in Italy’s regions over the long term, i.e. roughly from the second half of the nineteenth century up to the present day. The results are linked to newly available evidence for regional value added in order...
