ItemOvercoming measurement error problems in the use of survey data on expectations(BLACKWELL PUBLISHING, 2007-09)Survey data frequently requires conversion from qualitative responses to quantitative series and it is often asserted that the conversion procedures introduce measurement errors that render the series unusable in structural modelling. We investigate the nature and treatment of the measurement error that arises when conversion procedures are used to obtain direct measures of expectations. We use simulation experiments to demonstrate the need for the adequate treatment of conversion errors and show that a procedure proposed to ‘purge’ the series of conversion error is extremely successful in circumventing the problems. We illustrate the procedures in empirical applications using business survey data.

ItemDeregulation as (welfare reducing) trade reform: The case of the Australian wheat board(Wiley, 2007-08-01)State trading enterprises are distinguishable from private, commercial firms by the nature of their exclusive rights and objectives. Deregulation of the Australian Wheat Board is used to illustrate the effects of these rights and objectives on trade and welfare. Theoretical models are specified and the effects measured through calibrated, partial equilibrium models. It was found that the successive deregulations of the Australian Wheat Board caused it to switch from being equivalent to an export subsidy to, today, being equivalent to an export tax. At the same time, deregulation has not necessarily been welfare enhancing.

ItemThe child health/family income gradient: Evidence from England(ELSEVIER, 2007-03-01)Recent studies using Canadian and US data have documented a positive relationship between family income and child health, with the slope of the gradient being larger for older than younger children [Case, A., Lubotsky, D., Paxson, C., 2002. Economic status and health in childhood: the origins of the gradient. American Economic Review 92, 1308-1334; Currie, J., Stabile, M., 2003. Socioeconomic status and child health: why is the relationship stronger for older children? American Economic Review 93, 1813-1823]. In this paper we explore whether or not these findings hold for England, analysing a sample of over 13,000 children (and their parents) drawn from the Health Survey for England. While we find consistent and robust evidence of a significant family income gradient in child health, using the subjective general health status measure, the slope of the gradient is very small. Moreover, we find no evidence that the slope of the gradient increases with child age. Furthermore, we find no evidence of such a gradient with more objective measures, based on nurse examinations and blood test results. Together these results suggest that family income is not a major determinant of child health in England. Finally, we provide some evidence that nutrition and family lifestyle choices have an important role in determining child health and that child health is highly correlated within the family.

ItemCannabis prices and dynamics of cannabis use(ELSEVIER SCIENCE BV, 2007-05-01)This paper uses duration models and self-reported cannabis histories from young Australians to study the dynamics of cannabis use. We find that low cannabis prices are associated with early initiation into cannabis use. While the decision to quit does not appear to be directly influenced by price, we find that the younger an individual is when they start using cannabis the less likely they are to quit. Therefore, low cannabis prices lead to early use and because of that they lead to a low quit rate and hence a longer duration of use.
