A number of studies have tested whether, globally, per capita incomes are converging over time. To date, the majority of studies find no evidence of absolute convergence, but many find evidence of conditional convergence, i.e. convergence having controlled for differences in technological and...

A number of recent studies have illustrated the link between health and economic growth. This paper argues that a key mechanism through which health affects growth is via total factor productivity (TFP). We first estimate TFP based on a production function and then estimate the determinants of...

This study adds to the emerging literature examining empirically the link between population size, other demographic factors and pollution. We contribute by using more robust estimation techniques and examine two air pollutants. By considering sulfur dioxide, we become the first study to...
