We extend the standard human capital earnings function to include dispersion in the return to schooling by treating the return as a random coefficient. If the rapid expansion in participation in higher education has been brought about by dipping further into the ability distribution, we should...

We apply a new estimator to the measurement of the economic returns to education. We control for endogenous education, unobserved ability and measurement error using only the natural heteroscedasticty of wages and education attainment. Our prefered estimate, 6.07%, is closer to the OLS estimate...

This paper uses cross section data to investigate whether education and ability are substitutes or complements in the determination of earnings. Using a measure of cognitive ability based on tests taken at ages 7 and 11 we find, unlike most of the existing literature, clear evidence that the...

It is clear that education has an important effect on wages paid in the labour market However it not clear whether this is due to the role that education plays in raising the productivity of workers (the human capital explanation) or whether education simply reflects the ability of the worker...

In this paper a rich and innovative dataset, the International Adult Literacy Survey, is used to examine the impact of functional literacy on earnings. The IALS surveys 12 OECD countries and sub-regions via a consistent questionnaire and includes a number of tests of numeracy and literacy, as...

This paper uses cross section data to investigate whether the returns to education vary with the level of ability. Using a measure of cognitive ability based on tests taken at ages 7 and 11 we find, unlike most of the existing literature, clear evidence that the return to schooling is lower for...
