We use a sharp, exogenous and repeated change in the value of leisure to identify the impact of student effort on educational achievement.  The treatment arises from the partial overlap of the world's major international football tournaments with the exam period in England.  Our data enable a...

We develop a model of endogenous skill-biased technical change in developing countries.  The model reconciles wildly dispersed existing estimates of the elasticity of substitution between more and less educated workers.  It also produces an estimating equation for the elasticity, which allow...

The empirical literature on the economics of happiness has grown rapidly, and much has been learned about the determinants of subjective well-being.  Less attention has been paid to its normative implications.  Taking China as a case study, this paper first summarises empirical results on the...

Poor people often do not make investments, even when returns are high.  One possible explanation is that they have low aspirations and form mental models which ignore some options for investment.  This paper reports on findings of an innovative experiment to test this in rural Ethiopia. ...

Using data from experimental games and household survey from 1,200 married couples in three sites in Ethiopia, this paper uses different versions of a voluntary contribution mechanism to test for household efficiency.  The experimental and econometric analyses provide many interesting results...
