Abstract: This study compares the impact of sugar-sweetened beverages (SSBs) tax between moderate and high consumers in Australia. The key methodological contribution is that price response heterogeneity is identified while controlling for censoring of consumption at zero and endogeneity of expenditure by using a finite mixture instrumental variable Tobit model. The SSB price elasticity estimates show a decreasing trend across increasing consumption quantiles, from -2.3 at the median to -0.2 at the 95th quantile. Although high consumers of SSBs have a less elastic demand for SSBs, their very high consumption levels imply that a tax would achieve higher reduction in consumption and higher health gains. Our results also suggest that an SSB tax would represent a small fiscal burden for consumers whatever their pre-policy level of consumption, and that an excise tax should be preferred to an ad valorem tax.

Abstract: Understanding who in the population is psychologically resilient in the face of major life events, and who is not, is important for policies that target reductions in disadvantage. In this paper we construct a measure of adult resilience, document its distribution, and test its predictability by childhood socioeconomic circumstances. We use a dynamic finite mixture model applied to 17 years of panel data, and focus on the psychological reaction to ten major adverse life events. These include serious illness, major financial events, redundancy and crime victimisation. Our model accounts for non-random selection into events, anticipation of events, and differences between in iduals in the immediate response and the speed of adaptation. We find considerable heterogeneity in the response to adverse events, and that resilience is strongly correlated with clinical measures of mental health. Resilience in adulthood is predictable by childhood socioeconomic circumstances the strongest predictor is good childhood health.
