Are there bubbles in the art market? The detection of bubbles when fair value is unobservable
No full textThe purpose of this paper is to look for bubbles in the Art Market using a structure based on steady state results for TAR models and appropriate definitions of bubbles recently put forward by Knight, Satchell and Srivastava (2011). The usual method for investigating bubbles is to measure prices as deviations from fair value. We assess whether it is meaningful to define a fair value of art and conclude that it is very challenging empirically to implement any definition. We then treat fair value as zero in one instance and unobservable in the other case and in both cases provide evidence of bubbles in the art market

Suburban nostalgia : the community building potential of urban screens
No full textUrbanely nomadic residents are increasingly forgoing the potential of locale based serendipitous encounters in favour of digitally mediated interactions within their walled garden of existing social networks. This limits a sense of community in urban neighbourhoods to members of one’s social network, but what of interactions with those outside of these networks, such as inhabitants of residential spaces? We report on our pilot study of open ended interviews which investigates the different user archetypes whose needs we consider when designing social technology for urban spaces. We propose a design to extend the sense of community in urban neighbourhoods beyond pure network sociality. Through a lens of ‘suburban nostalgia’ we envision how neighbourhood interactions might be retrofitted in new ways through civic engagement in the enhancement of environments

Dramatic character development personas to tailor apartment designs for different residential lifestyles
No full textThis chapter reports on research work that aims to overcome some limitations of conventional community engagement for urban planning. Adaptive and human-centred design approaches that are well established in human-computer interaction (such as personas and design scenarios) as well as creative writing and dramatic character development methods (such as the Stanislavsky System and the Meisner Technique) are yet largely unexplored in the rather conservative and long-term design context of urban planning. Based on these approaches, we have been trialling a set of performance based workshop activities to gain insights into participants’ desires and requirements that may inform the future design of apartments and apartment buildings in inner city Brisbane. The focus of these workshops is to analyse the behaviour and lifestyle of apartment dwellers and generate residential personas that become boundary objects in the cross-disciplinary discussions of urban design and planning teams. Dramatisation and embodied interaction of use cases form part of the strategies we employed to engage participants and elicit community feedback
Steady-state distributions for models of bubbles: their existence and econometric implications
No full textThe purpose of this paper is to examine the properties of bubbles in the light of steady state results for threshold auto-regressive (TAR) models recently derived by Knight and Satchell (2011). We assert that this will have implications for econometrics. We study the conditions under which we can obtain a steady state distribution of asset prices using our simple model of bubbles based on our particular definition of a bubble. We derive general results and further extend the analysis by considering the steady state distribution in three cases of a (I) a normally distributed error process, (II) a non normally (exponentially) distributed steady-state process and (III) a switching random walk with a fairly general i.i.d error process We then examine the issues related to unit root testing for the presence of bubbles using standard econometric procedures. We illustrate as an example, the market for art, which shows distinctly bubble-like characteristics. Our results shed light on the ubiquitous finding of no bubbles in the econometric literature
A Loss Aversion Performance Measure
No full textThe purpose of this paper is to propose an innovative method of evaluating the performance of active fund managers, by introducing to the field of performance measurement the more appealing loss aversion utility theory. We combine the latter to an already established performance measure developed by Grinblatt and Titman (1989), to construct a new and improved method of performance evaluation and then apply it for two distinct risk preference scenarios. The new methodology is used to evaluate the performance of a sample of UK pension funds over a 10-year period using the Knight, Satchell and Tran (1995) family of distributions for the excess returns. The results vary depending on the assumption of risk preferences: the results obtained in the first scenario are controversial, whereas for the second scenario, the new measure does seem to pick up on the timing skills exhibited by active fund managers and then reward them accordingly.Performance measures, Loss Aversion, Pension funds, KST Family, Active management
Urban informatics for rural knowledge economies
No full textThis position paper provides an overview of a proposed study that seeks to design and develop tools, methods and applications of urban informatics to promote an innovation culture and knowledge economy in regional Queensland. The National Broadband Network has the potential to leapfrog regional Queensland to join the knowledge economy, but effective applications and content strategies are required. The Edge is the Queensland Government’s Digital Culture Centre to engage young people in the technology/culture nexus. This position paper provides an overview of a proposed study that will set up Living Labs at The Edge and in a new precinct in rural Queensland (Goondiwindi) as sites to trial strategies and applications that engage people in entrepreneurial thinking, sustainability initiatives, and new creative practices across the urban and rural boundaries
