Numerous empirical studies show a positive correlation between educati
on and economic development. However, little is known about the underl
ying processes, and while a contribution of primary and secondary educ
ation to economic development is generally acknowledged, many critics
argue that the poorer countries may gain nothing from investing in ter
tiary education. To shed more light on this question, this study draws
on regressions of the growth rate of per capital income on different
variables for educational attainment, as well of course as referring t
he other most important growth factors (accumulation of physical capit
al, technical progress, the possibility of 'catching up', and a countr
y's openness to trade). Based on a data-set covering 75 countries from
1960-1990, it is shown that tertiary education in less developed coun
tries has a significant impact on economic development, provided that
there are no 'educational imbalances'.
