Labour markets, like all market institutions, exhibit structural and dynamic characteristics. Both the structural and dynamic characteristics of labour markets inevitably change and evolve over time in response to a host of exogenous and endogenous factors. In the case of the Australian labour market, structural changes are reflected in significant shifts in the industry and occupational composition of employment, the decline of full-time work and the concomitant rise in part-time and atypical forms of employment, demographic changes in the labour force, as well as changes in social and individual preferences. Dynamic shifts can be found in cyclical pattern of employment and wages growth, the growth in labour mobility, and transitions between various labour market states.
The starting point for this paper is that these structural and dynamic changes have given rise to an increase in the likelihood that individuals will experience a transition between various labour market states, and a greater diversity in the range of transitions they may experience over their working life. This acceleration in the rate of transition generates ‘transition costs’ for both employers and employees, as well the likelihood of mismatch between employer and employee working time preferences. As a consequence, existing labour market policy regimes, based on the traditional model of labour market participation over the life course may not provide adequate protection for most workers today.
Gunther Schmid (1998) and others have proposed institutional reforms which promote ‘transitional labour markets’. Transitional labour market institutions are those that allow individuals (and firms) to successfully adjust to critical events. While transitional labour market institutions may consist of traditional ‘active labour market policy’ mechanisms, Schmid and others have proposed a range of innovative policy responses which allow individuals (and firms) to adjust the intensity of their abour market participation over the life cycle. In this paper we use the general approach of advocated by the transitional labour market concept to do three things. First, we investigate the processes by which the nature of labour market transitions has changed over time. Second, we review the range of policy options available to government to smooth labour market dysfunctions associated with labour market transitions, with the objective of ensuring labour markets operate more efficiently and more equitably. Third, we focus on one possible way in which an existing labour market institution, Long Service Leave (LSL), could be reformed to make way for a more comprehensive transitional labour market institution in the form of a ‘working time bank’.

Supply chains are complex adaptive systems for which final performance depends upon numerous interdependent decisions made by numerous firms which synthesise inputs from various resources systems.  The dynamic interdependent behaviour of social, economic, material and informational resource systems within eco-industrial settings that support the built environment life cycle supply chains can be studied at the supply chain level.  The impact of megaprojects is significant and holds promise to explore the impact of decisions on various systems as it combines project and system boundaries.  Megaoprojects considered as major events within systems can produce critical revolutionary impacts on the systems within which they are embedded.  The decisions that are made on megaprojects are central to risk management.  typically major infrastructure projects are procured through a form of public private partnership (PPP).  The core principle of PPP is value for money which refers to the best available outcome attempting to take account of all benefits, costs and risks over the whole life of the procurement.  In this paper the focus is on Australia where there has been considerable acitivity in the use of PPPs.  With recent national infrastucture packages proposed to stimulate the economy due to the global financial crisis, decision modelling on risks is a revelant and critical matter not only in practice but also in the research community.  PPPs encourage the whole-of-lifecycle approach in the procurement and management of public sector assets by transparently recognising the costs and risks associated with the whole life of the required service or facility, thus integrated whole of life supply chains can be considered.  By creating a single point of responsibility for an entire project from inception through operation, a strong incentive is created for thinking about the effects that a design or construction decision will have on the effectiveness and efficiency of managing and maintaining a facility during its operational life.  The decision to procure holistic supply chains becomes a much more viable commercial reality in the PPP environment than previously considered in the usual commercial construction spot transactional approach.  These types of decisions tend to be imprecise, approximate and complex requireing justification and reasoning logic rather than the classical 'truth' logic.  The purpose of this paper is to develop a theoretical decision framework which combines interdependency and multi-values logic for supply chain procurement modelling.
