“…In conclusion, from a theoretical perspective, the SDR value should reflect both society's preference for present consumption rather than future one (social value approach) and the yield that could be obtained from the economic resources spent in a project in the best alternative investment (social cost approach). However, both values for the SDR could be quite different (Angelsen, 1991;Arrow & Kurz, 1970;Arrow et al, 2004;Feldstein, 1964;Fern andez-Baca, 2011;Gollier, 2011;Laibson, 1997;Moore et al, 2004;Roumboutsos, 2010;Souto, 2003).…”

A basic question for the assessment of the fairness of a project financing formula on successive generations is to determine what is the most appropriate method to group the affected individuals over the years. The generational approach in the "Intergenerational Redistributive Effects Model" (IREM) deals with it through the ad-hoc concept of overlapping annual generations. This concept requires establishing the number of years (or timespan) included in the generation and how to incorporate in it those individuals living in years that are not the central one. To do so in a way that reflects the sensitivity of society to the effects of a major transport infrastructure project, specific surveys with a novel approach were designed. The outputs from the survey carried out in Catalonia show evidence suggesting that discount functions should tend to decline at a higher rate in the short term than in the long term. Thus, future impacts of transport investments, both future socioeconomic net benefits and financial burdens, should be considered less important than immediate (present) outcomes in the decision-making process. Further, there are reasons to consider that discounting is not neutral to reflect the social interest of large-scale transport projects for the successive generations involved.

Abstract:There is a variety of PDSs (project delivery systems) in today's construction industry. This leads to confusion when it comes to selecting the most suitable PDS for a specific project. The wrong selection decision might lead eventually to reduced profit margins or perhaps financial losses to PSFs (professional service firms). This research proposes a conceptual framework that helps PSFs in the selection of one or more suitable PDSs for their construction operations. The framework uses SWOT (strengths, weaknesses, opportunities and threats) analysis as a tool for assessing each PDS considered in this research. The PDSs included in the framework are design-bid-build, design-build, construction management agency, public-private partnerships and integrated project delivery. The main aim of this research framework is to enhance decision-making efficiency in PDS selection for PSF operations.

“…The analysis is based on an 80 year time horizon; subsequently, discount rates of 1%, 3% and 5% are used to allow a comparison of net present values over time. These discount rates reflect a longer term, intergenerational consideration of the time value of money [38]. The use of lower rates also reflect the likely contribution of a more diverse forest to public good and other non-timber values not quantified within the analysis.…”

Abstract:Increasing the resilience of ecological and sociological systems has been proposed as an option to adapt to changing future climatic conditions. However, few studies test the applicability of those strategies to forest management. This paper uses a real forest health incident to assess the ability of forest management strategies to affect ecological and economic resilience of the forest. Two landscape scale strategies are compared to business as usual management for their ability to increase resilience to a climate-change induced mountain pine beetle outbreak in the Kamloops Timber Supply Area, British Columbia, Canada for the period 1980 to 2060. Proactive management to reduce high risk species while maintaining or increasing diversity through reforestation was found to be more resilient in terms of the metrics: post-disturbance growing stock, improved volume and stability of timber flow, and net revenue. However, landscape-scale indicators of diversity were little affected by management. Our results were robust to uncertainty in tree growth rates and timber value and show that adapting to climate change through improving the resilience of forested landscapes is an economically viable option.
