Illegal migrants, tourism and welfare : a trade theoretic approach

Many countries receive illegal migrants but are reluctant to accept them due to possible negative externalities. We provide a rationale for not policing illegal migration by linking it to the tourism industry. By paying illegal migrants less than local workers, the relative price of the non-traded goods is shown to be lower than it would be in the absence of such workers. An expansion in tourist trade, under certain intensity conditions, necessarily raises resident welfare and employment. This tourist boom necessarily lowers the welfare of the illegal migrants. It is established that an increase in tourism increases the supply of illegal migrants.

Competition and unitization in oil extraction : a tale of two tragedies

This paper compares two organizational modes for extracting oil from a common pool: unitization and competitive extraction. The analysis suggests that the general presumption that unitization is surplus enhancing relative to competitive extraction may not always be valid due to contractual incompleteness associated with unitization contracts. While competitive extraction suffers from the tragedy of the commons, unitization can be subject to the dual tragedy of the anticommons. This provides an explanation for the puzzle confronting the oil industry that firms are often reluctant to voluntarily enter unitization agreements.

Competition and efficiency : overseas students and technical efficiency in Australian and New Zealand universities

Economic theory suggests that competitive pressures will impact on organisational efficiency. In recent years, universities in Australia and New Zealand have faced increased competition for students. The aim of this paper is to explore the efficiency of Australian and New Zealand public universities and to investigate the impact of competition for students from overseas on efficiency. Output distance functions are estimated using panel data for the period 1995-2002 for Australia and 1997-2003 for New Zealand. The results show that competition for overseas students has led to increased efficiency in Australian universities. However, competition for overseas students appears to have had no effect on efficiency in New Zealand.

The influence of child support and welfare on single parent families

Many single parent families in Australia are on low-incomes and many depend on Centrelink Parenting Payments as their main source of income which is comparatively low to meet their basic living costs. The impact of low income on child health and social inclusion is discussed.

Sperm competition and offspring viability at hybridization in Australian tree frogs, Litoria peronii and L. tyleri

Hybridization between closely related species often leads to reduced viability or fertility of offspring. Complete failure of hybrid offspring (post-zygotic hybrid incompatibilities) may have an important role in maintaining the integrity of reproductive barriers between closely related species. We show elsewhere that in Peron's tree frog, Litoria peronii, males more closely related to a female sire more offspring in sperm competition with a less related rival male. Observations of rare 'phenotypic intermediate' males between L. peronii and the closely related L. tyleri made us suggest that these relatedness effects on siring success may be because of selection arising from risks of costly hybridization between the two species. Here, we test this hypothesis in an extensive sperm competition experiment, which shows that there is no effect of species identity on probability of fertilization in sperm competition trials controlling for sperm concentration and sperm viability. Instead, there was a close agreement between a male's siring success in isolation with a female and his siring success with the same female in competition with a rival male regardless of species identity. Offspring viability and survival, however, were strongly influenced by species identity. Over a 14-day period, hybrid offspring suffered increasing mortality and developed more malformations and an obvious inability to swim and right themselves, leading to compromised probability of survival. Thus, hybridization in these sympatric tree frogs does not compromise fertilization but has a strong impact on offspring viability and opportunity for reinforcement selection on mate choice for conspecific partners.

Foreign aid, wage inequality and welfare for a small open economy with tourism

While the welfare effect of foreign aid has been extensively analyzed, the impact on the distribution of income has received less attention. At the same time, there has been recent work on tourism where it is complementary to aid in improving welfare.By combining these two strands, this paper concentrates on wage inequality in developing countries.We find that an increase in aid in the form of tied aid can lower the relative price of nontraded goods. The rent extracted from tourists declines, reducing welfare of domestic residents. In addition, the fall in the nontradable price can widen the wage inequality between skilled and unskilled workers.Thus, increased foreign aid may have detrimental effects on national welfare and the distribution of income. Rising wage inequality is confirmed by numerical simulations.

Social work and welfare education without discrimination : are we there yet?

The Australian Human Rights Commission (AHRC) has identified education as one of five crucial issues relating to the settlement of African Australians into the Australian community from a human rights perspective (AHRC 2009:5). In this paper I advocate that social work and welfare work in Australia are placed in important and multi dimensioned positions in relation to our complicities, responsibilities and potentialities with this educational human rights issue. As a Technical and Further Education (TAFE) welfare and University social work educator, I offer an outline of the ‘mutual respect inquiry approach’ that developed between myself and Southern Sudanese Australian students as a basis for discussion, reflection and change. I seek to stimulate thinking and action, particularly among those welfare work and social work educators, practitioners and students who identify as critical and anti-oppressive, to consider how these approaches can be realised and reshaped in practice to enhance not only Southern Sudanese Australians' right to education that is 'without discrimination', but indeed all students in our diversity.

Balancing act : competition and cooperation in US Asia-Pacific regionalism

While the United States is an important Asia-Pacific actor, its engagement with the region is complex and often difficult. Not only must US regionalism balance the diverse requirements of an ambitious policy agenda, but also US policy norms and priorities often clash with those of other regional actors. This has important implications for the capacity of the United States to provide regional leadership. Recent years have seen growing policy convergence between the United States and other Asia-Pacific actors, particularly in economic terms, but US regionalism continues to feature competition alongside collaboration.

Software developer policies : economics and s 46 of the Competition and Consumer Act 2010

This article considers the impact of developer policies that hinder or restrict cross platform application development. We suggest that policies that hinder or restrict cross platform development have the potential to erode competition within the market for smartphones. The article also considers the relevance of dominance measures in software markets, arguing that conventional economic approaches may not be applicable. Furthermore, while most monitoring activities tend to focus primarily on protection of consumers, the article points out that modern electronic/information technology markets are multi-sided and there is a need for monitoring of practices designed to attract and retain the favour of developers. While the article is written in the context and application of the applicable Australian legislation, this being s 46 of the Competition and Consumer Act 2010 (Cth), our findings are equally relevant to other jurisdictions.

Australia's health 2006 : the tenth biennial report of the Australian Institute of Health and Welfare

The report shows that Australians generally have good health and are privileged to have a range of health care services available to them. There are stark exceptions to this that can be confronting—even if well-known already—notably the generally much poorer health status of Indigenous Australians.

Health care service provider and funding arrangements are both increasingly complex and increasingly costly to both individuals and taxpayers. A continuing challenge is how to balance both the complementary and competitive perspectives of government and non-government agencies, professional groups, and small businesses. Overall, national expenditure on health was 9.7% of GDP in 2003–04; and average health expenditure per person has grown by an average 3.8% each year between 1997–98 to 2002–03. Expenditure on aids and appliances, health research and pharmaceuticals contributed more to this growth than other areas.

While the ageing of the population is having a significant impact on the number and type of health care services delivered, high quality services for children continue to be a priority. Australia’s health 2006 has a special chapter focusing on children and their health. The chapter highlights the fact that while our children are generally very healthy, there are concerns that their ongoing health could be affected by more and more of them becoming overweight or obese. Levels of diabetes are now rising among our children and it is a continuing concern that asthma and mental health problems affect so many of them.

Australia's health 2004 : the ninth biennial report of the Australian Institute of Health and Welfare

Australia's Health 2004 is the ninth biennial health report of the Australian Institute of Health and Welfare. It is the nation's authoritative source of information on patterns of health and illness, determinants of health, the supply and use of health services, and health services expenditure. The report also includes a special chapter on the health of older Australians. Australia's Health 2004 is an essential reference and information resource for all Australians with an interest in health.
