In a recent paper, García-Mainar and Montuenga-Gómez (2005) apply the generalized IV model of Hausman and Taylor to estimate education returns of wage earners and the self-employed in Portugal and in Spain. Our examination reveals several problems which relate to the validity and documentation...

We propose a simple investment model which shows that, in the presence of fluctuations in and uncertainty about the opportunity cost of time, marginal individuals may choose to delay their education if the opportunity cost of time is temporarily high. Importantly, it is when the completion of...

Twins-based estimates of the return to schooling feature prominently in the labor economics literature. The validity of such estimates hinges critically on the assumption that within-pair variation in schooling is explained by factors which are unrelated to wage earning ability. This paper...

Swedish elementary school children stopped receiving written end of year report cards following a grading reform in 1982. Gradual implementation of the reform creates an opportunity to investigate the effects of being graded on adult educational attainments and earnings for children in the...

Using cultural transmission, we develop a model that gives some microfoundation to the impact of residential neighborhood on children's educational attainment and then test it using the UK National Child Development Study. We find that, for high-educated parents, the better the quality of the...

Can educational institutions explain occupational choice between wage employment and entrepreneurship? This paper follows Lazear's (2005) Jack-of-all-trades hypothesis according to which an individual with a more balanced set of abilities is more likely to enter into entrepreneurship. In the...

It is extraordinarily difficult to determine the extent to which the gender wage gap reflects discriminatory behaviors by employers or differences in productive capacities between men and women. We note that where piece-rate work is performed, wages should in principle reflect productivity...

Our study combines a near-exhaustive sample of CEOs of Swedish companies with data on their cognitive and non-cognitive ability and height at age 18. Although CEOs, and large-company CEOs in particular, have better traits than the population on average, they are neither exceptional in any of the...

A quality-adjusted specification of labor is suggested which allows firm training to affect labor efficiency. To assess the cost and productivity effects, this specification is integrated into a flexible neoclassical cost function. The empirical analysis uses panel data for eight plants in the...
