Abstract This paper presents a methodology for examining the net benefit of site rehabilitation after an ecological disaster. While restoration of the site seems reasonable on the face of it, the cost of proactive restoration can be very high. In this article, we present a tool for decision makers to decide on the optimal route to rehabilitation – proactive or natural rehabilitation (or some combination thereof). We present a case study of an ecological catastrophe that occurred in June 2017 at an ephemeral desert stream in the south of Israel. We estimated the restoration costs and the benefits of restoration over the relevant time frame using a contingent valuation method. Comparing the present costs and benefits revealed a net present value of ILS 355.5 million in favor of proactive restoration of the stream. We also demonstrate that not all sections of the stream pass the benefit cost test, so a higher net benefit could be achieved through partial restoration. Our study demonstrates the importance of cost–benefit analysis when policy makers are contemplating proactive versus natural restoration.

This paper presents the operational procedures involved in incorporating the environmental costs in the cost–benefit analysis of a hydro-electric project. The proposed project, if implemented, would result in the loss of 2,800 hectares of tropical forests and dislocation of two settlements of about 200 families who are currently dependent on the forests for their livelihood. The forests are mainly used for extracting reed – a material used both by traditional artisans and the paper-pulp industry. The potential environmental costs and benefits of the project are identified and approximate estimates of some of these costs are made for items such as carbon sequestration, bio-diversity, and so on, based on similar estimates made elsewhere. These estimated environmental costs are incorporated into the analysis, and the hypothetical estimate of the non-use value, which would make the project's net benefit zero, is estimated under different discount rates. The analysis brings into sharp focus some crucial factors that have a direct bearing on the social trade-off involved in the project choice.

Abstract This paper sets out to explore to what extent integrating employment effects, equity, and risk aversion within cost–benefit analysis (CBA) affect the economic appraisal of a climate change adaptation project designed to protect against flood risk in a region of Bilbao (Basque Country, Spain). Four CBAs are conducted: (i) a standard CBA; (ii) a standard CBA considering equity; (iii) a standard CBA considering equity and employment; and (iv) a standard CBA considering equity, employment and risk aversion. All CBAs are conducted using a time frame of 2014–2080 and considering a 100-year return period under a middle of the road emission scenario (RCP4.5). A sensitivity analysis is also undertaken. Results suggest that the economic efficiency of the adaptation investment is contingent on what types of considerations are included within CBA. Integrating elements of employment, equity and risk aversion can strengthen or weaken the case for action (leading to higher or lower net-present values) and (depending on the discount rate chosen) may even be the deciding factor for determining whether a particular action should be carried out or not (whether the net-present value is positive or negative).

Efficiency And Effectiveness

An in-depth investigation of the costs and benefits of geographic information system (GIS) implementation in the Illinois Department of Transportation (IDOT) is presented. The investigation addresses a critical need to determine the organizational impact and cost-effectiveness of this enter-prisewide information technology to achieve the greatest benefit. IDOT conducted an enterprise wide effort to portray GIS capabilities and to identify candidate GIS projects. Fourteen major GIS projects were selected on the basis of management priority, ease of implementation, and user commitment. A comprehensive cost-benefit analysis was developed over fiscal years 1995 through 2004. Costs were reasonably estimated from historical costs of the GIS investigation effort and future costs of GIS technical support and user area resources. The greatest portions of costs, over the 10-year time frame, were for personnel (67 percent) and consultant services (19 percent). For the more difficult benefits determination, the research employed two categories of benefits: efficiency and effectiveness. Efficiency benefits would result from the automation of previous manual efforts, such as special-purpose cartographic production, with GIS outputs. Effectiveness benefits arise from traditionally intangible areas, such as increased integration and accessibility of information for improved decision making. Effectiveness benefits were estimated conservatively for two high-priority areas: accident analysis and program development. The result of the cost-benefit analysis of GIS implementation yielded a net present value of $2.9 million and an internal rate of return of 99.8 percent over the analysis period. This provided IDOT management with knowledge for strategic resource allocation decisions.

The paper analyzes shortcomings of economic impact studies based mainly on input- output models that are often employed in Russia as well as abroad. Using studies about sport events in the USA and Olympic Games that took place during the last 30 years we reveal advantages of the cost-benefit analysis approach in obtaining unbiased assessments of public investments efficiency; the step-by-step method of cost-benefit analysis is presented in the paper as well. We employ the project of Sochi-2014 Winter Olympic and Paralympic Games in Russia to evaluate its efficiency using cost-benefit analysis for five accounts (areas of impact), namely government, households, environment, economic development, and social development, and calculate the net present value of the project taking into account its possible alternatives. In conclusion we suggest several policy directions that would enhance public investment efficiency within the Sochi-2014 Olympics.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

OBJECTIVE: To perform a cost-benefits analysis of a clinical pharmacy (CP) service implemented in a Neurology ward of a tertiary teaching hospital. METHODS: This is a cost-benefit analysis of a single arm, prospective cohort study performed at the adult Neurology Unit over 36 months, which has evaluated the results of a CP service from a hospital and Public Health System (PHS) perspective. The interventions were classified into 14 categories and the costs identified as direct medical costs. The results were analyzed by the total and marginal cost, the benefit-cost ratio (BCR) and the net benefit (NB). RESULTS: The total 334 patients were followed-up and the highest occurrence in 506 interventions was drug introduction (29.0%). The marginal cost for the hospital and avoided cost for PHS was US$182±32 and US$25,536±4,923 per year; and US$0.55 and US$76.4 per patient/year. The BCR and NB were 0.0, -US$26,105 (95%CI -31,850 – -10,610), -US$27,112 (95%CI -33,160–11,720) for the hospital and; 3.0 (95%CI 1.97–4.94), US$51,048 (95%CI 27,645–75,716) and, 4.6 (95%CI 2.24–10.05), US$91,496 (95%CI 34,700–168,050; p < 0.001) for the PHS, both considering adhered and total interventions, respectively. CONCLUSIONS: The CP service was not directly cost-benefit at the hospital perspective, but it presented savings for forecast cost related to the occurrence of preventable morbidities, measuring a good cost-benefit for the PHS.

<p>New Time of Use (ToU) tariff scheme known as Enhanced ToU (EToU) has been introduced on 1st January 2016 for industrial customers in Malaysia. EToU scheme is the advanced version of current ToU where the daily time frame is divided into six period blocks, as compared to only two in the existing ToU. Mid-peak tariff is introduced on top of peak-hour and off-peak tariff. The new scheme is designed to reduce Malaysia’s peak hour electricity demand. On customer side, they could be benefited from the low off-peak tariff by simply shifting their consumption. However, it depends on their consumption profile and their flexibility in shifting their consumption. Since EToU scheme is voluntary, each customer needs to perform cost-benefit analysis before deciding to switch into the scheme. This paper analyzes this problem by considering EToU tariff scheme for industry and customer’s electricity consumption profile. Case studies using different practical data from different industries are presented and discussed in this paper.</p>

The aim of this study was to calculate the cost benefit analysis and economic viability of seedling production on the floating bed at Nazirpur Upazila in Pirojpur district of Bangladesh. The study area was selected purposively and 50 households (HHs) were surveyed through purposive sampling technique from a population of 80 households. From the results of those primary data, it was found that 68% farmers were engaged in seedling production as business purpose, and 30% as both own and business, 21 vegetables and spices seedlings were cultivated in the studied area. Average per square meter cost for floating seedling cultivation found BDT (Bangladeshi taka) 281 and benefit was BDT 401. The net benefit of floating agriculture found BDT 120 and with a BCR of 1.43. Income from floating seedlings mainly utilized in winter vegetable cultivation (Kandi), mainstream agriculture, business, house development and land purchase etc. Fifty percent (50%) of the floating farmers mentioned various constraints regarding floating seedling production such as lack of government aid, higher interest from NGOs and lack of capital. Among the surveyed respondents, 64% agreed that floating cultivation is effective to combat climate change and 76% replied as beneficial to the environment. Although floating agriculture is an indigenous age-old practice in the South-western region of Bangladesh, it can be replicated with the help of subsidy and agro-technology.
