Data for discrete ordered random variables are often characterised by "excessive" zero observations. Traditional ordered probit models have limited capacity in explaining the preponderance of zero observations, especially when the zeros may relate to two distinct situations of non-participation...

We investigated marijuana, alcohol and tobacco consumption using micro-unit data from the Australian National Drug Strategy Household Surveys. We estimated a multivariate probit (MVP) model to allow for correlations across participations of different drugs and a sequential model to study...

This article investigates factors affecting the participation in marijuana, cocaine and heroin using micro-unit data from an Australian national survey on recreational drugs. Accounting for cross-drug correlation potentially induced by unobserved personal characteristics such as individual...

The data used, and the methods and assumptions fundamental to the development of an equilibrium displacement model (EDM) of the Australian sheep and wool industries specified in Mounter et al. (2007), are contained in this report. The national sheep flock is disaggregated into Merino and...

Around $100 million has been spent annually on R&D and promotion in the Australian red meat industries in recent years. The R&D investments are made throughout the production, processing and marketing chain in both the grass and grain finished sectors. Promotion investments are made in both...

Despite continuing controversy, economic surplus concepts have continued to be used in empirical cost-benefit analyses as measures of welfare to producers and consumers. In this paper, the issue of measuring changes in producer and consumer surplus resulting from exogenous supply or demand...

This paper examines evidence from Australia on the factors associated with binge drinking and several alcohol-related antisocial and unlawful behaviours. In particular, to quantify the negative externalities of excessive alcohol consumption by product type, our primary focus is the link with...
