We develop a simple human capital model for optimum schooling length when earnings are stochastic, and highlight the pivotal role of risk attitudes and the schooling gradient of earnings risk. We use Spanish data to document the gradient and to estimate individual response to earnings risk in...

Using Norwegian cancer registry data we study twin and non-twin siblings to decompose variation in cancer at most common sites and cancer mortality into a genetic, shared environment and individual (unshared environmental) component. Regardless the source of sibling variation, our findings...

There exists a strong educational gradient in cancer risk, which has been documented in a wide range of populations. Yet relatively little is known about the extent to which education is causally linked to cancer incidence and mortality. This paper exploits a large social experiment where an...

We apply a recently proposed method to disentangle unobserved heterogeneity from risk in returns to education. We replicate the original study on US men and extend to US women, UK men and German men. Most original results are not robust. A college education cannot universally be considered an...

We combine a survey and an experiment with real pay-out among Peking University students to measure and validate individual risk attitudes. The experiment involves choosing between a cash payment and playing a lottery. The survey questions ask for the reservation price of a hypothetical lottery...

This paper analyses the effect of risk attitudes of firm owners on profits among micro and small enterprises (MSEs) in Lagos, Nigeria. Higher risk perceptions are shown to have a significant positive effect on profits, whereas risk propensity has a negative or no effect. Education, age, being...

The risk of investment in schooling has largely been ignored. We assess the variance in the rate of return by surveying the international empirical literature from this fresh perspective and by simulating risky earnings profiles in alternative options. choosing parameters on basis of the very...

We ask individuals for their reservation price of a specified lottery and deduce their Arrow-Pratt measure of risk aversion. This allows direct testing of common hypotheses on risk attitudes in three datasets. We find that risk aversion indeed falls with income and wealth. Entrepreneurs are less...

This paper surveys migration to and from the Netherlands since the sixteenth century with an emphasis on the post-war period. Existing studies on the labour market performance of immigrants and ethnic minorities are considered and some new results from our recent research are presented. <BR><BR>
