We estimate the harm from smoking during pregnancy upon child birth outcomes, using a rich dataset on a cohort of … mothers and their births. We exploit a fixed effects approach to disentangle the correlation between smoking and birth weight … from smoking is explained by unobservable traits of the mother. Smoking tends to reduce birth weight by 1.7%, but has no …

Gaps in welfare attainment between boys and girls in China have attracted international attention. In this paper demand analysis is used to try and uncover the factors which may be driving the emergence of the gender gaps. Drawing on household expenditure data from a poor (Sichuan) and rich...

We estimate semiparametric Engel curves for rural Pakistan using a large household survey. This allows us to obtain consistent estimates of the effects of household size and composition on consumption patterns even when these demographic variables are correlated with an unknown function of...

This paper shows that smoking intensity, i.e. the amount of nicotine extracted per cigarette smoked, responds to …, we provide new evidence on the importance of cotinine measures in explaining long-run smoking behaviour and we … investigate the sensitivity of smoking cessation to changes in excise taxes and their interaction with smoking intensity. …

We introduce a kernel-based estimator of the density function and regression function for data that have been grouped into family totals. We allow for a common intra-family component but require that observations from different families be in dependent. We establish consistency and asymptotic...

We establish valid theoretical and empirical Edgeworth expansions for density-weighted averaged derivative estimates of semiparametric index models.

We propose a new estimator for nonparametric regression based on local likelihood estimation using an estimated error score function obtained from the residuals of a preliminary nonparametric regression. We show that our estimator is asymptotically equivalent to the infeasible local maximum...

The nonparametric censored regression model, with a fixed, known censoring point (normalized to zero), is y = max[0,m(x) + e], where both the regression function m(x) and the distribution of the error e are unknown. This paper provides estimators of m(x) and its derivatives. The convergence rate...
