INFRASTRUCTURE INVESTMENT AND GROWTH: SOME EMPIRICAL EVIDENCE

This paper explores empirically the relationship between infrastructure and economic growth by including the data of expenditure in infrastructure as a share of GDP in traditional growth cross-country regressions. Since results are inconclusive, the paper elaborates some new indicators of investment in infrastructure employing physical units of infrastructure. They are positively and significantly correlated with growth in two different samples of countries. Copyright 1998 Western Economic Association International.
