Individual time preference determines schooling enrolment. Moreover, smoking behavior in early ages has been shown to be highly related to time preference rates. Accordingly, we use smoking at age 16 as an instrument for schooling in order to cope with ability bias in a returns to education...

Individual absolute risk aversion is measured for a sample of 1373 male household heads, using the 1995 wave of the Survey on the Income and Wealth of Italian households. This measure, conditional on financial and real wealth and household income, is used as an instrument for attained education...

We establish the validity of higher order asymptotic expansions to the distribution of a version of the nonlinear semiparametric instrumental variable considered in Newey (1990) as well as to the distribution of a Wald statistic derived from it. We employ local polynomial smoothing with variable...

In a sample selection or treatment effects model, common unobservables may affect both the outcome and the probability of selection in unknown ways. This paper shows that the distribution function of potential outcomes, conditional on covariates, can be identified given an observed variable V...

This paper explores the relationship between the degree of division or fractionalization of a country’s population (along ethnolinguistic and religious dimensions) and both political instability and government consumption, using a neoclassical growth model. The principal idea is that greater...
