ESSAYS ON PARENTS' SOCIOECONOMIC STATUS, CHILD HEALTH OUTCOMES AND SMOKING BEHAVIOURS

摘要: This thesis comprises a collection of three distinct essays on the relationship between parents’ socioeconomic, child health outcomes and smoking behaviours. Chapter 2 investigates extent to which misclassification errors in self-reported affects estimates impact parental income adolescents aged 11-15 years old. Smoking participation is modelled using cotinine-validated as binary dependent variables two separate probit models. A comparison marginal effects estimated from both models suggest that misreported leading biased adolescent smoking. Estimates model are robust different specifications account for exposure second-hand smoke. Income-related inequality (the concentration index) also underestimated due variations across quantiles. Chapter 3 uses decomposition methods decompose differences distribution saliva cotinine children/adolescents high low socioeconomic backgrounds. The applied mean-based (Oaxaca-Blinder) method allow quantiles quantile regression recentered influence function methods). Group characteristics (composition effect) accounts larger proportion total difference log compared group these (structural effect). composition effect attributable within home explains more at lower quantiles, indicative passive higher active On other hand, household smoking.
