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 separately the determinants of participation and the levels of consumption. The MVP results indicate significant and positive correlations across all three drugs through unobservable characteristics, with the correlation coefficient between marijuana and tobacco being the highest. The MVP approach allows for better prediction of conditional and joint probabilities, providing valuable information for policy makers in a multidrug framework.

The results of our research contribute to assessing the benefits and costs of hospital stays-and their alternatives-in a quantitative manner. Instead of discharging patients early to alternative care, it would be more desirable to address underlying causes of adverse events. However, this may prove costly, difficult, or impossible, at least in the short run. In such situations, our research supports hospital managers in making informed treatment and discharge decisions.

This paper discusses the major transformation of higher education that has been under way in China since 1999 and evaluates its potential global implications. Reflecting China’s commitment to continued high growth, this transformation focuses on major new resource commitments to tertiary education and significant changes in organisational form. All of these changes have already had large impacts on China’s higher educational system and are beginning to be felt by the global educational structure. This focus on tertiary education differentiates the Chinese case from other countries who earlier at similar stages of development instead stressed primary and secondary education.
