Impacto das condições de saúde na renda do trabalho: evidências para o chefe e o cônjuge do domicílio

Abstract

The purpose of the present study is to estimate the impact that a poor health condition of the head of the household exerts on the income of his / her spouse in order to know which effect is most significant - the income effect, where the spouse starts to work more to cover the lost income, or - the substitution effect, where the spouse starts to work less to care for the individual with poor health. The impact of the head of household's poor health condition on his own income and the impact of the spouse's poor health condition on his income were also estimated and Lewbel (2012) method that generates domestic instruments from residuals heterocedasticity. To reach this result was used the estimation by average treatment effect to verify the effect in different points of the distribution, correcting for the sample selection bias. The results show that a poor health condition (or being diagnosed with some chronic illness) of both the head of the household and the spouse causes negatively affect their own individual income, whereas an adverse condition of the head positively impacts the salary of the spouse, which possibly goes to work more in order to supplement lost income from that negative impact on your partner's health.
