In this paper we use principal components augmented regressions (PCARs), partly in conjunction with model averaging, to determine the variables relevant for economic growth. The use of PCARs allows to effectively tackle two major problems that the empirical growth literature faces: (i) the...

In recent years there has been a growing interest in the impact of inequality on economic growth. Both theoretical and empirical approaches have produced ambiguous results on sign and size of this relationship. Although there is a considerable part of the literature that considers inequality...

While the effect of higher public debt levels on economic growth has received much attention, the literature partly points to contradictory results. This paper applies meta-regression methods to 826 estimates from 48 primary studies. The unweighted mean of the reported results suggests: a 10...
