A spacing trial was established near Thunder Bay, Ontario in 1950. This trial consisted of black spruce (Picea mariana (Mill.) B.S.P.), white spruce (Picea glauca (Moench) Voss.), and red pine (Pinus resinosa Ait.) each established at three different spacings: 1.8 m, 2.7 m, and 3.6 m. This study examines the differences in growth and crown development as attributed to initial spacing, after 37 years. In addition, a benefit/cost analysis was performed to evaluate the economic efficiency of the various species/spacing combinations. Diameter at breast height, live crown length, and crown width, all exhibited significant (P < 0.001) increases as initial spacing increased, irrespective of species, but, height demonstrated a decreasing trend (P < 0.020). Gross total and merchantable stem volume per tree increased for all species as initial spacing increased; however, volume production per unit area decreased significantly for all species as spacing increased. The shift to higher-valued products from the wider-spaced plantations appeared to provide the best economic return. As a result of both greater merchantable volumes and greater percentages of these volumes available as a higher-valued product, benefit/cost ratios for red pine (0.995 to 1.337) were greater than those for the spruces (0.595 to 0.866). Although red pine currently represents less than 4% of Ontario's total regeneration effort, the results from this study suggest it deserves further consideration on some boreal sites.

In October 1990, the Kings County (Brooklyn, NY) District Attorney's Office implemented the Drug Treatment Alternative to Prison (DTAP) program to divert nonviolent felony drug offenders from prison to community-based residential drug treatment. This article presents an estimate of the costs and benefits of the DTAP program based on a cohort of DTAP participants and prison comparisons who entered treatment or prison in 1995–1996 and were tracked for 6 years. The analysis focuses on the criminal justice system (CJS) costs associated with criminal recidivism. Findings show that the DTAP program is cost-beneficial compared to the usual criminal justice process (benefit-cost ratio equals 2.17 after 6 years).

Rice is an annual plant belongs to family Poaceae. It is the major staple food crop of Nepal and can be grown from plain to mountainous regions of Nepal. The crop varieties differ from each other in terms of production cost, gross return and gross margin. The objective of this study was to analyze benefit cost ratio for production of different rice varieties. The study was carried out in Kapilvastu district of Nepal in 2018. A sample size of 120 respondents were selected randomly. Four different rice varieties: Gorakhnath, Radha-4, Ramdhan, and Sawa were used for the study. The primary data were collected through household survey using interview schedule. The data were analyzed using Statistical Package for Social Sciences and Microsoft Excel. The average cost of production was amounted to NRs. 77,100/ha for all four rice varieties. Sawa variety had the highest gross return (NRs. 1,01,212.5/ha). The benefit cost ratio was observed highest for Sawa (1.312) and lowest for Radha-4 variety (1.005). Sawa is the most economic rice variety in terms of gross and net production in the study area. The findings will help farmers to choose and cultivate rice variety with greater profitability. It is recommended that concerned authorities should give emphasis on subsidies, farmers training and ensuring floor price of rice.  Int. J. Appl. Sci. Biotechnol. Vol 7(2): 222-226

This study provides an economic evaluation for a Land Ferry, which is a rail system capable of carrying trucks and all other types of vehicles, passengers, and cargo. The Land Ferry system involves a sliding loading system to roll heavy loads onto a flatbed; as a result, loading and unloading of all vehicles and cargo could be accomplished simultaneously. The evaluation for this system included (1) the design of a new track alignment over which the Land Ferry system would run, (2) evaluation of various sources of power, (3) estimation of how many local jobs the Land Ferry would generate, and (4) a benefit-cost analysis. It was estimated that the Land Ferry would create over 45,788 temporary jobs in Nevada during the three-year construction period and 318 permanent jobs during operation. The majority of the benefits were attributed to savings in travel time ($356.4 M), vehicle operating costs ($1000.4 M), reduction of accidents ($544.6 M), and pavement maintenance ($503.2 M). These benefits would be a consequence of the shift of trucks from the highway, thus resulting in higher speeds, decrease fuel consumption, and decrease vehicle maintenance costs. The overall benefit-cost ratio of 1.7 implies a cost-effective project.

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.

The economic assessment of transportation projects is evolving from a reliance on user benefits (travel time, cost, or safety) to encompass a wider spectrum of potential benefits, fostered by advances in economics and recognition that different project modes deliver different portfolios of benefits. Sponsors develop projects to address specific problems in their communities. This progression in how investments are evaluated opens the door for projects whose outcomes span a variety of benefit categories rather than concentrating on traditional user benefits and permits an improved intermodal comparison of candidate investments. Transit and intercity rail projects are particular beneficiaries of the broader project assessment approach. This paper presents a case study of how a comprehensive approach to project assessment was applied to the Northern Lights Express project that would reintroduce passenger rail service between the cities of Minneapolis and Duluth, Minnesota, the state's largest economies. Owned and operated by BNSF Railway, Amtrak's service in the corridor ended in 1985. Six stations are planned: Target Field in Minneapolis; stations in Coon Rapids, Cambridge, and Hinckley, Minnesota; a station in Superior, Wisconsin; and Union Depot in Duluth. The goal for the analysis was threefold: ( a) to confirm that the investment would yield a positive return; ( b) to communicate with partners, stakeholders, and the public about the project's expected outcomes; and ( c) to contribute to the selection of an alternative. The benefit–cost ratio was estimated for eight alternatives that varied by physical alignment and service plan.

The paper examines the profitability of two improved poultry systems (semi-intensive and intensive egg production system)i in the South-West and South-South zones of Nigeria using descriptive statistics, farm budget analysis approach and the benefit-cost analysis. The data for the study were ob­tained through a multi-stage sapling approach from 70 poultry farmers selected from four states (Edo and Delta in South-South; Lagos and Oyo in the South -West) in the study area. Empirical evidence from the analysis shows that the poultry farmers are predominantly male and mostly single. A greater proportion (80%) of them fell between the ages of 31-50 years and had a least secondary school education. Majority of the farmers (86%) used black nera breed because of its high productiv­ity, resistance to diseases and environmental stress and good quality carcass when disposed as spent layer The study further reveals that differences exist in profitability between the two groups of poultry farmers as the net income of farmers using the battery cage system was about 1.8 times the net income of farmers using deep litter system. However; the benefit-cost ratio indicates that both group of farmers are making profit since the benefit-cast ratio of their poultry business exceed one.

AbstractAn areawide program for biological control of the alfalfa weevil showed expected economic benefits of $2.2 billion, expressed in present value terms. Alfalfa producers and consumers of livestock products are the main beneficiaries. The control program was highly successful, with a benefit/cost ratio of about 91. Not all areawide biological pest control programs will be as successful; a benefit-cost analysis like the one described here should be performed before areawide control is initiated to identify programs expected to provide economic benefits.

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.

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.

Transportation research projects are a vital element for transportation agencies to accumulate new technology and knowledge to improve the efficiency and safety of transportation infrastructure. The purpose of this paper is to develop benefit cost analysis (BCA) tools to assist transportation agencies in evaluating transportation research projects. The BCA tools provide analysis methods for estimating the benefits for changes in the level of service (LOS) of a roadway, reductions in the vehicle travel time, changes in vehicle operating costs and reductions in the number of crashes. Three case studies were investigated to illustrate the usage of the BCA tools. The first case study evaluated the effectiveness of variable speed limit systems implemented along I-80 in southern Wyoming. The BCA tools estimated a benefit cost ratio of 6.64 indicating that the implementation of the project was economically justifiable. The second case study was a recent study investigating and developing mitigation strategies for the effects of truck traffic along the I-80 in southern Wyoming resulting in a benefit cost ratio of a 9.23 indicating that the project had the potential to be economically viable upon implementation. The final case study evaluated the effect of wildlife overpass and underpass crossings on the migrations of pronghorn and mule deer. The benefit cost ratio for the research project was 0.42 indicating that the project was not economically beneficial after the first year of implementation. The case studies indicated that the BCA tools are a beneficial tool for quantifying the economic benefits of a transportation research project.
