Abstract
A key question in economics is whether poor countries will automatically close the income gap with rich countries. However, different empirical methods yield different answers – growth regressions suggest convergence, whereas tests of distribution dynamics suggest divergence. This column discusses recent research that reconciles these two strands of the literature. It extends the benchmark growth regression model to include a parameter that determines the share of new technologies a country can adopt each year. The result is that, although each country converges to a growth path, the growth paths themselves may divergeI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
