Cost-benefit Analysis of the Virginia Expanded Food and Nutrition Education Program (EFNEP)

Rajgopal, Radhika Jr. 15 September 1998 (has links)
Each year approximately 7,500 low-income Virginia families are enrolled in the Expanded Food and Nutrition Education Program (EFNEP), administered through the Virginia Cooperative Extension (VCE). Chronic disease and health conditions cost society an estimated $250 billion each year in medical charges and lost productivity. It has been assumed that the numerous diet and food-related changes made by EFNEP participants will lead to a reduction in the risk of chronic disease among homemakers, and perhaps, other family members. Thus, the improved diets and behaviors resulting from EFNEP participation may result in substantial future savings in healthcare costs among participants. This study explores the possibility of potential economic benefits for the Virginia EFNEP participants. In 1996, the Virginia Cooperative Extension was awarded a grant from the Cooperative State, Research, Education, and Extension Service, United States Department of Agriculture (CSREES, USDA) to conduct a cost-benefit study of EFNEP in Virginia. Though computation of the cost-benefit ratio for the Virginia adult EFNEP includes both direct and indirect benefits, this study addressed only the assessment of the direct tangible benefits based on the savings from economic costs of avoided diseases. Existing EFNEP data for the 1996 fiscal year was used to identify optimal nutritional behaviors that can delay or prevent the onset of certain chronic diseases and health conditions. The economic costs of diseases were identified from scientific literature and translated as potential benefits. The administration costs of EFNEP were also compiled. The total direct tangible benefit for the diseases and conditions identified was estimated to be $17,770,722. Along with the indirect tangible benefits ($321,462), the total tangible benefits for the Virginia EFNEP was calculated to be $18,092,184. The direct tangible costs associated with the Virginia EFNEP in 1996 was $1,922,204. The benefit-cost ratio for the Virginia EFNEP for the 1996 fiscal year for the subset of the population practicing the optimal nutritional behaviors is calculated at $9.41/$1.00 (a $9.41 return for every $1 invested in EFNEP in Virginia). Also, a benefit of $2.45 to $1.00 was calculated when only 25% of those participants practicing optimal nutritional behaviors were assumed retain these behaviors through life. For a program of the magnitude of EFNEP, these results are very gratifying. / Ph. D.

EXAMINING A SOCIAL COST-BENEFIT ANALYSIS OF THE PANAMA CANAL EXPANSION PROJECT

du Plessix, Justin Christopher 07 April 2011 (has links)
Upon completing the construction of the Panama Canal in 1914, vessels sailing between the Atlantic and Pacific Oceans were provided an alternative to navigating the southern tip of South America. In order to accommodate future demand of Canal services, the Panama Canal Authority (ACP) in 2006 began planning a Canal expansion. The ACP enlisted URS Holdings, Inc to do a social cost-benefit analysis of the project. This thesis thoroughly examines the contents of this analysis and critiques the content and methodology of the study. The URS analysis suffers from numerous problems, including a lack of monetary values for potentially significant social and environmental impacts of the Canal expansion, a failure to distinguish pecuniary versus non-pecuniary externalities, causing the social benefits of the expansion to be grossly overstated and a questionable choice of discount rate which make a more positive picture of the private returns from expanding the Canal.

The Dollars and Cents of Driving and Cycling: Calculating the Full Costs of Transportation in Calgary, Canada

Dekker, Kaely January 2016 (has links)
Many cities across the globe are working to facilitate cycling as a sustainable transportation mode through changes to public policy and investments in infrastructure. Examining the costs and benefits of both driving and cycling using the cost benefit analysis (CBA) framework developed in Copenhagen provides an opportunity to identify private and social costs associated with these modes of transport with respect to environmental, social, and economic impacts. This paper outlines the methods used to calculate the per-kilometre costs of driving and cycling in Calgary, Canada, utilizing real-world data and methods from Canadian and global best-practice with the Copenhagen CBA framework as a guide. Transportation costs were calculated for travel time, vehicle ownership, health, collisions, air pollution, climate change, noise, roadway degradation, congestion, and winter maintenance for both driving and cycling. When the costs borne by both individuals and society are calculated for Calgary (in 2015 Canadian dollars) driving costs $0.83 per kilometre and cycling costs $0.08 per kilometre. When the social costs of transport are isolated, the cost of driving one kilometre is $0.10, while cycling one kilometre generates a net social benefit of $0.35. The results of this research show that the Copenhagen CBA framework can be applied in jurisdictions outside Denmark to calculate environmental, social, and economic costs of driving and cycling.

Development of cost benefit analysis model of accident prevention on construction projects

Ikpe, Elias Okede January 2009 (has links)
The Health and Safety Executive estimated the annual cost to British employers and other duty holders failing to comply with health and safety requirements to be up to £18 billion. It is estimated that the construction industry contributed £2billion of these appalling statistics. To date, health and safety management is still perceived as being costly and counterproductive in the construction industry. This research investigated the net benefit of accident prevention and explored the relationship between preventative costs and these benefits, with a view to drawing attention to the economic consequences of effective/ineffective management of health and safety by contractors in the UK construction industry. The need to investigate the cost of accident prevention in relation to overall benefits of accident prevention is therefore deemed necessary. A quantitative research methodology was employed in investigating these costs and benefits within the UK construction industry. From the ratio analysis small contractors spend relatively higher proportions of their turnover in total on accident prevention than medium and large contractors, and medium contractors spend a higher proportion of their turnover in total on accident prevention than large contractors. The results also show that medium and small contractors gain relatively higher proportions of their turnover in total as benefits of accident prevention than large contractors. The benefits of accident prevention far outweigh the costs of accident prevention by a ratio approximately 3:1. The relationships between these costs and benefits were examined. The costs of accident prevention were found to be positively and significantly (P < 0.005) associated with benefits of accident prevention. These associations were modelled using simple linear regression, and from these models it can be inferred from the results that the more contractors spend on accident prevention the more they derive benefits of accident prevention, which would improve health and safety performance on construction sites. ii The developed model was subsequently validated using experts and practitioners opinion from the UK construction industry. This developed model should provide good guidance to assist contractors in developing effective and efficient health and safety management for UK construction industry.

Institute messen effiziente Werbung

Löbler, Helge, Langbein, Norman 10 February 2017 (has links) (PDF)
"Die Hälfte unserer Werbeausgaben ist umsonst, aber wir wissen nicht welche." Diese in der Werbebranche häufig strapazierte Aussage ist heute glücklicherweise nicht mehr gültig. Werbungtreibende Unternehmen möchten zunehmend wissen, was die Werbung bewirkt, die sie bei Agenturen in Auftrag geben. Für die Agenturen ihrerseits wird der Nachweis effizienter Werbung zunehmend zum Erfolgsfaktor. Natürlich wird es immer diejenigen Kritiker der Effizienzprüfung von Werbung geben, die da sagen, daß bei zunehmender Orientierung der Werbegestaltung an der Effizienz die Kreativität auf der Strecke bliebe. Dazu ist mindestens zweierlei zu sagen : Erstens ist zu bezweifeln, daß die Kreativität durch zunehmende Effizienz der Werbung in den Hintergrund rückt. Märkte, auf denen Informationen und Emotionen gehandelt werden, zeigen eher, daß durch schärferen Wettbewerb und damit zunehmende Effizienzanforderungen mehr Kreativität gefordert wird. Wohlgemerkt: gefordert und vielleicht nicht gefördert. Aber es scheint hier wie in vielen anderen Bereichen unserer Wirtschaft: Zum einen wünschen wir uns den harten Wettbewerb lieber für die anderen und zum zweiten wünschen sich eher die Starken eine Leistungsorientierung als die Schwachen. Zweitens muß man sagen: Selbst wenn die Kreativität nicht mehr der Hauptmaßstab für gelungene Werbung ist - so what? Sollen denn die Konsumenten und Werbung treibende Unternehmen Kreativität bezahlen, die ihnen nicht nützt? Der Trend ist klar: Die Effizienzmessung der Werbung wird zunehmend zum Erfolgsfaktor für die Agenturen. Man kann das ja nicht wollen, aber man kann nicht verhindern, daß es andere tun. Deshalb lohnt es, sich damit zu befassen.

The cost-benefit analysis of extending the grazing season in beef cattle production in Atlantic Canada

Téno, Gabriel January 2016 (has links)
The aim of the study was to integrate economics, forage agronomy and livestock production data to determine the economic costs and benefits of management techniques that can extend the grazing season for beef production in Atlantic Canada. The results of the study show that extending the grazing season is financially and economically beneficial for both an Atlantic beef farmer and the whole Atlantic community. Extending the grazing season could be thus an alternative solution to enhance beef farm viability in Atlantic Canada. It can also contribute to the sustainable development of beef cattle production through its benefits for environmental protection. The results of this study reflect the necessity of supporting and promoting the adoption of extended grazing season practices in Atlantic beef production. This support and this promotion could involve increasing awareness, training on grazing management skills, diffusion at workshops and participatory research.

Risk and farmers' decisions to farm organically : the case of Devon (UK)

Barhoum, Saer Issa January 2010 (has links)
Over the past few decades, the organic sector in most developed countries has flourished. Growth in the sector has been paralleled by a substantial amount of research on several arenas (see Cobb et al. 1999; Robles et al. 2005; Jackson and Lampkin 2008; Lobley et al. 2009c; among others). Reasons for adopting organic farming have been studied in a variety of instances (Padel 2001a). Although there is a considerable body of evidence that supports the distinctly ‘risky nature’ of organic farming, our identification and understanding of how this nature affects farmers’ decisions whether or not to farm organically are limited (see, for example, Lockeretz 1995; Duram 1999; Midmore et al. 2001; Baecke et al. 2002; Hattam 2006). It seems that there has been widespread acceptance of the hypothesis that organic farmers are more likely to be risk-takers compared to non-organic farmers. Similarly, the hypothesis that organic farmers with Non-Farming Backgrounds (NFBs) may have different attitudes towards risk has not been investigated yet through detailed empirical analysis. Accordingly, this thesis seeks to analyse the importance of farmers’ willingness to take risk in organic farming in their decisions regarding the adoption of organic farming where it is assumed that there is a link between attitudes and behaviours. The thesis employs a variety of methods: a questionnaire; familiarisation; in-depth interviews; and secondary data. The findings of this thesis suggest that not all sources and types of risks associated with organic farming are differently perceived by non-organic and organic farmers. In Devon (i.e. the study area), more non-organic than organic farmers mentioned the existence of ‘farm-related risks’ and ‘risks related to farmers’ belief’. Further, ‘risks related to financial returns’ were perceived to be of concern by non-organic farmers compared to their organic counterparts. On the other hand, other types and sources of risks associated with organic farming were equally perceived to be of concern by both groups. As expected, the recent risky environment of organic farming played a significant role in this respect (see also de Buck et al. 2001; Flaten et al. 2005). The wider environment was moreover the cause of greater concern regarding production, market and institutional risks (as opposed to personal ones) among organic farmers in Devon at the time of the questionnaire survey, when compared to the level of concern at the time of adoption. This shows that perceptions of types and sources of risks associated with organic farming are subject to change across time (CRER 2002). Compared to their non-organic counterparts, organic farmers in Devon were willing to take risk in organic farming. With regard to risk in farming and to risk in general, more organic farmers expressed risk-taking attitudes than did their non-organic counterparts. Consequently, and based on the main reasons for adoption and non-adoption of organic farming, this thesis suggests that willingness to take risk in organic farming acts as an extremely significant trigger for the uptake of organic farming. This in turn confirms what has been emphasised by many researchers (see Baecke et al. 2002; Acs et al. 2005; Serra et al. 2008; among others). It also suggests that investigations into people’s behaviours and decisions in relation to a ‘risky activity’ should take into account their attitudes towards risk in that activity. This thesis, in common with other studies (e.g. Kaltoft 1999; Lobley et al. 2005), also shows evidence of heterogeneity among organic farmers. A small group of organic farmers in Devon from NFBs was in search of the ‘good life’ and wanted to produce public goods from organic farming. Although technical, market and institutional risks associated with organic farming were of concern to organic farmers from NFBs in this study, these farmers did not have distinct risk perceptions. In contrast, they had distinct attitudes towards risk in organic farming. More organic farmers from NFBs than organic farmers from Farming Backgrounds (FBs) were willing to take risk in organic farming. Finally, and in accordance with Morris and Potter’s (1995) work, this thesis has placed 79% of surveyed farmers in Devon on a typology which reflects the fact that farmers are not homogeneous. The ‘conditional non-organic farmers’ and ‘pragmatic organic farmers’ in this typology may, with varying degrees of ease, switch between organic and non-organic methods at any point in the future due to possible changes in their attitudes towards risk in organic farming. In contrast, the ‘resistant non-organic farmers’ and ‘committed organic farmers’ at the two extremes of this typology will very likely be resistant to changes in their current farming systems. Accordingly, a set of policy recommendations which may help to increase future organic adoption in the UK has been set forth.

Cost-benefit analysis of microgenerators : an integrated appraisal perspective

Harajli, Hassan A. January 2009 (has links)
The UK domestic building sector accounts for a substantial amount of the final energy demand and greenhouse gas (GHG) emissions. To this extent, the sector can play an important role in GHG abatement and energy demand reduction, essential objectives of a more ‘sustainable energy system’. Microgeneration, or production of electricity or heat from small-scale sources, have been advocated by some, including the Supergen ‘Highly Distributed Power Systems Consortium’ to which this thesis contributes, as important means towards achieving these objectives. In this thesis, three assessed microgenerators; specifically a 600W microwind system, 2.1 kWp photovoltaic (PV) and building-integrated photovoltaic (BIPV) systems, and a 2.8m2 solar hot water (SHW) system have been analysed through an ‘integrated appraisal toolkit’ in order to assess their respective economic and financial performance in current UK context. A cost-benefit analysis (CBA) is applied, based on outputs and results from energy analysis and life-cycle assessment (LCA), and other tools such as financial appraisal, cost-effective analysis (CEA), and simple multi-attribute ranking technique (SMART) are also performed in order to asses how these systems perform on an individual household level or when compared to other energy technologies. The CBA, which included environmental impacts quantified through the LCA, obtained negative net present values (NPVs) for all the assessed microgenerators with the exception of microwind in a high-wind resourced ‘open’ area with lower end capital costs. The NPVs in the financial appraisal, which excluded environmental impacts, yielded relatively poorer results still. Only with the proposed feed-in tariffs would the systems all achieve positive NPVs. Given that the CBA included a substantial qualitative part, alternative tools, such as CEA and multi-criteria evaluation were applied (in brief) in order to place the assessed systems in the context of other energy generating sources in the UK, and to enable a more confident decision with respect to whether these systems should be advocated or rejected.
