Childhood obesity has increased dramatically in the developed world. One cause of this trend, suggested by studies in the United States, is the increase in maternal employment. This paper explores if the causal relationship exists in Australia. Using recent data from the Longitudinal Survey of...

It is generally believed that intergenerational coresidence by elderly parents and adult children provides security for parents in their old age. In many countries, such intergenerational coresidence is the most common living arrangement. Using a nationally-representative dataset and a program...

I propose a nonparametric iid bootstrap procedure for the empirical likelihood, the exponential tilting, and the exponentially tilted empirical likelihood estimators that achieves sharp asymptotic refinements for t tests and confidence intervals based on such estimators. Furthermore, the...

The number of lone parent families in Australia has grown dramatically over the last twenty years, as has the level of public income support for this group. This paper develops a cross-section modelling framework which pays close attention to the complexities of the budget constraint and...

I propose a nonparametric iid bootstrap that achieves asymptotic refinements for t tests and confidence intervals based on the generalized method of moments (GMM) estimators even when the model is misspecified. In addition, my bootstrap does not require recentering the bootstrap moment function,...

The empirical evidence of the effect of intergenerational coresidence by elderly parents and their adult children on parental health remains fairly inconclusive. The aim of this paper is twofold: (1) to estimate a reliable coresidence effect and (2) to investigate why the coresidence effect can...

Under treatment effect heterogeneity, an instrument identifies the instrument-specific local average treatment effect (LATE). If a regression model is estimated by the two-stage least squares (2SLS) using multiple instruments, then 2SLS is consistent for a weighted average of different LATEs. In...
