Technology uncertainty and market collusion

In this paper, we propose technology uncertainty as a new factor relevant to market collusion. We analyze an infinitely repeated quantity game where, for each firm, the marginal productivity of the input employed in the production process is affected by an unobservable shock. Each firm faces technology uncertainty, measured by the variance of the shocks, in every period. We show that, under both grim trigger strategies and optimal punishments, technology uncertainty enhances cartel stability, suggesting that, in industries characterized by technology uncertainty, the actions of the antitrust authorities should be intensified. We also show that collusion is less likely when technology shocks are highly correlated, implying that regulators interested in deterring collusion should promote the formation of industrial clusters.

Regenerating rural social space? Teacher education for rural-regional sustainability

The complex interconnection among issues affecting rural-regional sustainability requires an equally complex program of research to ensure the attraction and retention of high-quality teachers for rural children. The educational effects of the construction of the rural within a deficit discourse are highlighted. A concept of rural social space is modelled, bringing together social, economic and environmental dimensions of (rural-regional) sustainability. This framework combines quantitive definitional processes with more situated definitions of rural space based on demographic and other social data, across both geographic and cultural formations. The implications of the model are examined in terms of its importance for teacher education.

Community resilience, climate change, sustainability & engagement : adventures in creative project-based education on the Eyre Peninsula

Teaching sustainability ethics and creative practical technological applications holistically, in a multi-disciplinary ethos, with real community engagement is fraught with pedagogical and logistical issues. This paper reviews a highly community-acclaimed tertiary course/project, offered at the School of Architecture, Landscape Architecture & Urban Design at the University of Adelaide, undertaken on the Eyre Peninsula in 1st semester 2009. The course successfully enhanced student appreciation of rural community capacity building and economic fragility issues while undertaking a project-based approach to interrogating and working with rural communities to devise and demonstrate potential micro-relevant design and planning initiatives that could strengthen community resilience, climate change adaptiveness, and validate natural resource management aims within townships. The project involved some 120 students in 6 host communities through 6 local municipalities with the full support of the Natural Resource Management (NRM) Board and Local Government Association (LGA).

The paper reviews the project, its historical evolution, aims, objectives, learning strategies, community aspirations and outcomes, and positions such against various professional education accreditation frameworks. The methodological learning process, including its philosophical, pedagogical and instruments outcomes are reviewed and interrogated. The student learning outcomes, University reputation impact, and community impact, professional practice knowledge and skill attributes, and instrumental outcomes are also reviewed drawing upon evidence derived from extensive meetings, questionnaire surveys, synergistic NRM-sponsored research projects, student evaluation of teachings (SELTS), and local media coverage of the project.

The project has received applause from the Australian Institute of Architects (AIA) and Australian Institute of Landscape Architects (AILA), and preliminary endorsement from the Planning Institute of Australia (PIA), as being integral to the School’s curriculum that achieves their professional accreditation expectations of key learning experiences relevant to climate change, master planning and design, and community engagement. The project offers a possible educational model that enriches student experience and learning and addresses recent generic university community engagement policy expectations.

Defining cultural sustainability in multicultural built environments

The Australian built environment is an arena where multicultural identity and difference are tangibly negotiated. What occurs on a daily basis in its cities is a complex series of negotiations between multiple communities, all of whom adapt their own cultures, as well as adopting elements from their surrounding environment. This paper investigates these issues by comparing the physical development within a contemporary Australian city with the social and cultural changes that have taken place in it. It asks the question. Whose culture should be sustained in this context, and on what basis? To what extent should the urban environment be reflecting of the changes, as much as the origins, of a relatively young settler society (notwithstanding the fact that its original inhabitants have a history that predates this settlement by thousands of years). More broadly, what constitutes cultural sustainability in a multicultural society, and how is, might, or should this be reflected in its built environment?

Beyond cliché – reclaiming the concept of sustainability

In closing his 2008 Myer Lecture, the scientist and environmentalist Dr Tim Flannery said that this century will be defined by the search for sustainability. How perilous therefore that nowadays there is so much overuse of the word 'sustainability' that it has become a cliche. Today's tertiary students studying architecture and energy-related subjects are so exposed to this linguistic devaluation that most of them appear to have accepted the vagueness of the term and are on their way to becoming the next generation of misusers. This paper presents a case study of an attempt to sharpen up the debate with some university students from these particular disciplines. A model of the four principles of sustainable development that has been found to be particularly useful is described. The students in question were challenged to think about the meaning of some of the words ascribed to new buildings and about the implications of the four principles to energy supply systems.

Corporate commitment to sustainability – is it all hot air? A review of the linkage between executive pay and sustainable performance

Across time, companies are increasingly making public commitments to sustainable development and to reducing their impacts on climate change. Management remuneration plans (MRPs) are a key mechanism to motivate managers to achieve corporate goals. We review the MRPs negotiated with key management personnel in a sample of large Australian carbon-intensive companies. Our results show that, as in past decades, the companies in our sample have MRPs in place that continue to fixate on financial performance. We argue that this provides evidence of a disconnection between the sustainability-related rhetoric of the sample companies, and their ‘real’ organisational priorities.

The politics of 'sustainability': a critical discourse analysis of Victorian Government policy discourse, 1999-2006

Since its emergence during the 1980s the idea of sustainability has come to provide the dominant frame within which environmental policy is debated. Thus, for many ‘sustainability’ represents the best way to address the economic, social and environmental effects of the myriad of environmental issues facing human societies, including biodiversity loss, soil erosion, pollution of waterways, ozone depletion and climate change. There are however, widely divergent views advocated as to what sustainability means, which has important implications for how serious environmental issues are understood to be, why they are important, what has caused them, and what needs to be done to address them. Given the diversity of such views, the consequences for policy making, and the likelihood of effective responses being developed, are self evident. Within this context, this thesis investigates the politics of sustainability, focussing particularly on the way in which it is defined, because of the implications this has for the way in which environmental issues are understood and addressed. Following a review of various approaches to analysing environmental policy (traditional, mainstream, ecopolitical and discursive), Norman Fairclough’s approach to discourse analysis (Critical Discourse Analysis) was identified as having particular merit. Fairclough’s approach avoids the assumption that policy issues exist independently of the way they are framed and offers a perspective on discourse that links the social theoretical concerns of Foucault with the micro level concerns of linguistics. It also provides a means for taking environmental policy analysis in directions that that have attracted relatively limited attraction, namely the detailed analysis of the ideological effects of language on environmental policy. In this thesis Fairclough’s approach is used to explore how three storylines of sustainability (sustainable development, environmentally sustainable growth and transforming society) and their associated discourses shaped environmental policy making in Victoria, Australia, between 1999 and 2006. In undertaking this analysis, I examined the political and institutional context informing policy making (social practice); the contested process of text production (discourse practice), and; the detailed wording of a policy text (textual analysis). A major policy statement on environmental sustainability released by the Victorian Government in 2005 is subjected to detailed analysis. Based on the analysis undertaken, the substantive finding from this research is that rather than moving beyond neoliberalism, the Victorian Government embraced an approach to sustainability that was informed by neoliberalism and (weak) ecological modernisation, which constructs sustainability in ways that limit its importance and constrain the types of responses that could be advocated. In doing so, it drew heavily on notions of natural assets and ecosystems services as ways to make sense of the environment and why it is important. The Victorian Government also highlighted that environmental issues are caused by the cumulative effects of individual choices, and emphasized the importance of individual choice and behavioural change as central features of sustainability, while restricting opportunities for more transformative ideas to be heard. The broader conclusion arising from this research is that approaches to environmental policy that rely on neoliberal and (weak) ecological modern discourses are flawed, because, in commodifying nature, limiting the nature and magnitude of change required, and placing responsibility onto individuals they offer a constrained understanding of the challenge of sustainability and what needs to be done about it. The overall contribution made by this research is an improved understanding of the discursive nature of the politics of sustainability and the influence of neoliberalism and ecological modernisation, the use of a methodology that has attracted relatively limited attention within environmental policy (despite its widespread use in other areas of policy) and the documentation of a period of significant environmental policy reform in Victoria.
