As the generation of food scrap, kitchen, and biodegradable wastes increases, the proper handling of these wastes is becoming an increasingly significant concern for most cities in Japan. A substantial fraction of food and biodegradable waste (FBW) ends up in the incinerator. Therefore, an analytic hierarchy process (AHP) benefit–cost analysis technique was employed in this study to compare different FBW treatment technologies and select the most appropriate FBW disposal technology for Oita City. The four FBW treatment options considered were those recommended by the Japanese Food Waste Recycling Law: anaerobic digestion, compost, landfill, and incineration, which is currently in use. The fundamental AHP was separated into two hierarchy structures for benefit analysis and cost analysis. The criteria used in these two analyses were value added, safety, efficiency, and social benefits for benefit analysis, and cost of energy, cost of operation and maintenance, environmental constraints, and disamenity for cost analysis. The results showed that anaerobic digestion had the highest overall benefit while composting had the least cost overall. The benefit–cost ratio result showed that anaerobic digestion is the most suitable treatment alternative, followed by composting and incineration, with landfill being the least favored. The study recommends that composting could be combined with anaerobic digestion as an optimal FBW management option in Oita City.

The cutting blade selection has been important issue for manufacturing systems due to the fact that it might affect productivity, precision and manufacturing cost. It is a multiple-criteria decision making problem for evaluating blade alternatives. In this paper, the hybrid approach is discussed,which combined the fuzzy AHP and benefit cost analysis. An improved AHP method based on triangular fuzzy number is used to analyze the cutting performance of blade alternatives. It can make up for the deficiency in the conventional AHP. Furthermore, the benefit cost analysis is carried out to evaluate the economic performance of alternatives. The benefit cost ratio is calculated by using the fuzzy AHP score and tool consumption cost. Tool consumption cost is obtained in consideration of tool service life and procurement cost. The optimal blade alternative with highest benefit/cost ratio can be found out. In addition, the proposed approach is also illustrated on a sample case study.

Benefit/cost analysis is a technique for evaluating programs, procedures, and actions; it is not a moral theory. There is significant controversy over the moral justification of benefit/cost analysis. When a procedure for evaluating social policy is challenged on moral grounds, defenders frequently seek a justification by construing the procedure as the practical embodiment of a correct moral theory. This has the apparent advantage of avoiding difficult empirical questions concerning such matters as the consequences of using the procedure. So, for example, defenders of benefit/cost analysis (BCA) are frequently tempted to argue that this procedure just is the calculation of moral Tightness – perhaps that what it means for an action to be morally right is just for it to have the best benefit-to-cost ratio given the accounts of “benefit” and “cost” that BCA employs. They suggest, in defense of BCA, that they have found the moral calculus – Bentham's “unabashed arithmetic of morals.” To defend BCA in this manner is to commit oneself to one member of a family of moral theories (let us call them benefit/cost moral theories or B/C moral theories) and, also, to the view that if a procedure is (so to speak) the direct implementation of a correct moral theory, then it is a justified procedure. Neither of these commitments is desirable, and so the temptation to justify BCA by direct appeal to a B/C moral theory should be resisted; it constitutes an unwarranted short cut to moral foundations – in this case, an unsound foundation. Critics of BCA are quick to point out the flaws of B/C moral theories, and to conclude that these undermine the justification of BCA. But the failure to justify BCA by a direct appeal to B/C moral theory does not show that the technique is unjustified. There is hope for BCA, even if it does not lie with B/C moral theory.

Early Childhood Interventions

We conduct a benefit-cost analysis of a package of early childhood interventions that can improve nutrition outcomes in Haiti. Using the Lives Saved Tool, we expect that this package can prevent approximately 55,000 cases of child stunting, 7,600 low-weight births and 28,000 cases of maternal anemia annually, if coverage reaches 90% of the target population. In addition, we expect these nutrition improvements will avoid 1,830 under-five deaths, 80 maternal deaths and 900,000 episodes of child illness every year. Those who avoid stunting will experience lifetime productivity benefits equivalent to five times gross national income per capita in present value terms, at a 5% discount rate. While previous benefit-cost analyses of this specific package have only estimated the lifetime productivity benefits of avoided stunting, this paper also accounts for reductions in fatal and non-fatal health risks. In the base case scenario, the annualized net benefits of the intervention equal Haitian gourdes 13.4 billion (USD 211 million) and the benefit-cost ratio (BCR) is 5.2. Despite these substantial benefits, the package may not be the most efficient use of a marginal dollar, with alternative interventions to improve human capital yielding BCRs approximately three to four times higher than the base estimate.

Economic Zones

Special economic zones (SEZs) in India have been in news due to their usefulness vis-à-vis adverse effects on economy. A good number of opponents opine that costs incurred by SEZs outweigh the benefits. However, it cannot be denied that SEZs have played a positive role in the welfare of the economy. Thus, to examine this issue, we carried out a social benefit–cost analysis (SBCA) on Noida Special Economic Zone (NSEZ) within the context of enclave model for the period of 2009–2016. The result shows the positive net present value and benefit–cost ratio greater than one under methodological assumptions. This infers that NSEZ is contributing towards the welfare of Indian economy. One interesting findings of the study is that NSEZ is generating positive gains to economy with the absence of various market distortions which could otherwise reduce the realised benefits. Hence, need arises to eliminate such distortions from outside area of economy also to make it competitive at global level. Therefore, it can be concluded that competitiveness of the Indian economy can be enhanced with the removal of market distortions and liberalisation of rules, regulation and policies for economic development activities. Hence, the Government of India should emphasise and make regulations and policies that encourage competitiveness of the industries. JEL Classification: D04, D61, F13, H2, J01

This paper demonstrates a new connection between benefit-cost analysis (BCA) and the national income and product accounts. The article computes an augmented measure of output, which is defined as gross domestic product (GDP) less environmental pollution damage. Environmental policy BCA is incorporated directly into the adjusted measure of output in two ways. In a particular time period, damages from pollution emissions are deducted from market GDP in a standard with-and-without policy comparison. Second, secular changes in damages, output (GDP), and correspondingly, in the adjusted measure of output are employed to estimate augmented rates of growth. Comparison to a no-policy counterfactual then yields the effect of the policy on the augmented measure of environmentally adjusted value added (EVA) growth. The empirical results suggest that, in the 30 states that adopted flue-gas desulfurization (FGD) technology between 2005 and 2011, augmented output grew 0.12% more quickly than in a no-scrub counterfactual. Augmented output growth in four states was at least 0.20% more rapid because of the installation of scrubbers. The paper reports that benefits-per-capita from FGD were mildly progressive and that counties with relatively large African American populations incur large benefits from FGD installation.

Institutions and administrators regularly have to make difficult choices about how best to invest resources to serve students. Yet economic evaluation, or the systematic analysis of the relationship between costs and outcomes of a program or policy, is relatively uncommon in higher education. This type of evaluation can be an important tool for decision makers considering questions of resource allocation. Our purpose with this essay is to describe methods for conducting one type of economic evaluation, a benefit–cost analysis (BCA), using an example of an existing undergraduate education program, the Freshman Research Initiative (FRI) at the University of Texas Austin. Our aim is twofold: to demonstrate how to apply BCA methodologies to evaluate an education program and to conduct an economic evaluation of FRI in particular. We explain the steps of BCA, including assessment of costs and benefits, estimation of the benefit–cost ratio, and analysis of uncertainty. We conclude that the university’s investment in FRI generates a positive return for students in the form of increased future earning potential.

AbstractJapan is one of the few rabies-free countries/territories which implement the policy of mandatory vaccination of domestic dogs. In order to assess the economic efficiency of such policy in reducing the economic burden of a future canine rabies outbreak in Japan, a benefit-cost analysis (BCA) was performed using probabilistic decision tree modelling. Input data derived from simulation results of published mathematical model, field investigation conducted by the authors at prefectural governments, literature review, international or Japanese database and empirical data of rabies outbreaks in other countries/territories. The current study revealed that the annual costs of implementing the current vaccination policy would be US$160,472,075 (90% prediction interval [PI]: $149,268,935 – 171,669,974). The economic burden of a potential canine rabies outbreak in Japan were estimated to be US$1,682,707 (90% PI: $1,180,289 – 2,249,283) under the current vaccination policy, while it would be US$5,019,093 (90% PI: $3,986,882 – 6,133,687) under hypothetical abolition of vaccination policy, which is 3-fold higher. Under a damage-avoided approach, the annual benefits of implementing the current vaccination policy in expected value were estimated to be US$85.75 (90% PI: $55.73 – 116.89). The benefit-cost ratio (BCR) was estimated to be 5.35 × 10−7 (90% PI: 3.46 × 10−7 – 7.37 × 10−7), indicating that the implementation of the current policy is very economically inefficient for the purpose of reducing the economic burden of a potential canine rabies outbreak. In worse-case scenario analysis, the BCR would become above 1 (indicating economic efficiency) if the risk of rabies introduction increased to 0.04 corresponding to a level of risk where rabies would enter Japan in 26 years while the economic burden of a rabies outbreak under the abolition of vaccination policy increased to $7.53 billion. Best-case analysis further revealed that the economic efficiency of the current policy could be improved by decreasing the vaccination price charged to dog owners, relaxing the frequency of vaccination to every two to three years and implementing the policy on a smaller scale, e.g. only in targeted prefectures instead of the whole Japan.

Orange Fleshed Sweet Potato

An investigation was conducted at the National Root Crops Research Institute, Umudike and at the Research Farm of Michael Okpara University of Agriculture Umudike, Umuahia, Abia State (Nigeria), to determine the benefit cost analysis of orange fleshed sweet potato (Ipomoea batatas L.) varieties under varying planting density (25,000; 33,333 and 50,000 plants/ha). The output of the production was computed by the use of benefit cost ratio (BCR) of the orange-fleshed sweet potato production. The benefit cost ratio analysis indicated that enterprise was successful and growing of the ‘Melinda’ variety at 50,000 plants/ha was a more profitable enterprise. The benefit cost-cost ratio of ‘Melinda’ variety at 50,000 plants/ha in 2015 and 2016 was 1.45 and 1.56 respectively while that of ‘Tio-joe’ at 50,000 plants/ha in both cropping seasons gave a benefit cost ratio of 1.14 and 1.42 respectively. The returns from selling of the vine cuttings brought about an incredible hike in the net return of the enterprise. ‘Melinda’ at 50,000 plants/ha is recommended to farmers as the most profitable venture in this experiment.
