Taxonomic issues related to biological control prospects for the ragweed borer, Epiblema strenuana (Lepidoptera: Tortricidae).

The ragweed borer, Epiblema strenuana (Walker, 1863), has a long history of use as a biological control agent against important weed pests in the family Asteraceae. Recently, E. strenuana has been reported feeding on the invasive perennials Ambrosia confertiflora and A.

Soft Budget Constraints in Public Hospitals.

A soft budget constraint arises when a government is unable to commit to not 'bailout' a public hospital if the public hospital exhausts its budget before the end of the budget period. It is shown that if the political costs of a 'bailout' are relatively small, then the public hospital exhausts the welfare-maximising budget before the end of the budget period and a 'bailout' occurs. In anticipation, the government offers a budget to the public hospital that may be greater than or less than the welfare-maximising budget.

Health services use and lifestyle choices of Indigenous and non-Indigenous Australians.

In many countries, the health outcomes of Indigenous populations are far worse than those of non-Indigenous populations. Two possible reasons for these differences are poor lifestyle choices and a lack of access to health services when ill. This paper uses Australian data on 17,449 adults, which was collected in the National Health Survey 2004-05 and the National Aboriginal and Torres Strait Islander Health Survey 2004-05, to examine whether Indigenous Australians make different lifestyle choices and health services use than non-Indigenous Australians.

The type species of Eucosma Hübner (Lepidoptera: Tortricidae: Eucosmini).

Eucosma Hübner is the largest genus in the Tortricidae with more than 290 named species. Historically, there has been confusion about the assignment of species to Eucosma and related genera, a problem which is perpetuated by the lack of a type specimen for the type species, E. circulana Hübner.

Revised world catalogue of Eucopina, Eucosma, Pelochrista, and Phaneta (Lepidoptera: Tortricidae: Eucosmini).

A revised world catalogue of Eucopina, Eucosma, Pelochrista, and Phaneta is provided. Assignment to genus is based on generic redescriptions by Gilligan et al. (2013).

Specialist payment schemes and patient selection in private and public hospitals.

It has been observed that specialist physicians who work in private hospitals are usually paid by fee-for-service while specialist physicians who work in public hospitals are usually paid by salary. This paper provides an explanation for this observation. Essentially, fee-for-service aligns the interests of income preferring specialists with profit maximizing private hospitals and results in private hospitals treating a high proportion of short stay patients.

The drug bargaining game: pharmaceutical regulation in Australia.

Many countries, including Australia, regulate the price consumers pay for pharmaceuticals. In this paper, the Australian Pharmaceutical Benefits Scheme (PBS) is modelled as a multi-stage game played between the regulator and pharmaceutical firms. Conditions are derived under which vertically differentiated firms are regulated and a number of issues are discussed.

Moral hazard and adverse selection in Australian private hospitals: 1989-1990.

The Australian hospital system is characterized by the co-existence of private hospitals, where individuals pay for services and public hospitals, where services are free to all but delivered after a waiting time. The decision to purchase insurance for private hospital treatment depends on the trade-off between the price of treatment, waiting time, and the insurance premium. Clearly, the potential for adverse selection and moral hazard exists.
