Questions related to Cost Benefit Analysis
We are doing a study of the counterfactual scenario in CBA. We are using empirical data from a large number of completed CBAs and, most likely, interviews with analysts and decision-makers. Some countries have guidelines that set out what the do-minimum scenario should include. I would also like to review relevant scientific literature on this issue, but I am struggling to find any studies. Tips on both guidelines and studies would be much appreciated.
I work on CBA/J (F) x DBA/2J (M) mice as abortion models. Since I received them, I have added walnuts, multivitamins, carrots, and apples to their diet in a limited way and maintained them in an animal facility, but so far I have not been able to see vaginal plugs in them. Does anyone have a suggestion for getting pregnant in this model?
Coal based power plants are one of the cheapest and more effective instruments to produce electricity. Many developed countries have already applied this plants and had the benefit from it. Although some of the countries have now stopped using coal based plants because of the negative impact being created towards the nature.
At present, many developing countries specifically in Asian and African region, are choosing Coal to produce more electricity as the demand is at the highest peak; even though a huge environmental degradation is happening due to these circumstances.
Social cost of carbon (SCC) is usually calculated by means of integrated assessment models (IAM), where the assumed social discounting rate has significant influence on the magnitude of SCC. Now, let's assume that I use a given SCC estimate in a cost-benefit analysis (CBA), say, to evaluate a project that would change the carbon storage capacity of soils in a given region. Conducting the CBA, I have to discount the costs and benefits - but this means that I discount the SCC that is already the result of a CBA (as any IAM implies a CBA); moreover, it may well be that the social rate of discount chosen in my hypothetical project evaluation differs from the one underlying the SCC estimate I use (for whatever reasons). Especially the former seems to amount to a double-discounting of the climate-externality related to the carbon storage capacity of the soil. Is such 'double discounting' a valid approach from a theoretical point of view?
I have a problem in growing Helicobacter pylori in solid media i.e. tryptic soy agar (TSA) and Columbia blood agar plate (CBA). HP growing good and are healthy in liquid media i.e. in tryptic soy broth(TSB). unfortunately, when I tried growing the bacterium in solid medium using Gas pouch in glass jar with 0.1% sodium boro-hydrate and DDW (in universal tube).
So I am interested in the simple and reliable method, how to obtain HP growth in solid agar media. Is it a good idea to use gas jar?
Thanks for all suggestions,
I want to ask a (not so) quick question about ecosystem services economics, urban planning, sustainable water drainage and cost-benefit analysis.
Whenever comparing different scenarii of urban greening or urban planning, in a cost-benefit anaysis (CBA), opportunity costs have to be integrated to represent the whole array of costs associated with a plan. The definition by Buchanan (1992) is good enough here : "Opportunity cost is the evaluation placed on the most highly valued of the rejected alternatives or opportunities", which is to say, it is the value that is sacrificed in any choice in a decision making situation. This cost is usually valued as the highest benefits that could have been produced by a choice, but that was forgone by the actual choice.
Now, when the subjects of a CBA, that is, the scenarii, are firm or private indivdual investments, the notion of opportunity cost is pretty thorough : it is the net revenue from the best forgone investment. And that's it.
However when dealing with urban planning, as with many other real world economics, it becomes trickier. The opportunity cost of using urban space is almost exclusively represented in the literature with land or real estate prices. The underlying hypothesis there is that construction would always be the next best profitable option for urban land, and that land prices are its best reflection. Fair enough, although it may debatable, as not all the alternatives of land use for a given land have a clear net benefit flow, far from it. Who knows, perhaps, at times, the next most profitable option for public welfare would be represented by the net flow of ecosystem services generated by a natural conservation option ?..
Anyhow, what if we are valuating water drainage systems scenarios ? Small urban green bioswales alongside the roads, designed for managing sustainably rainwater and stormwater ? It does not really eats up property lands, but rather public space, streets and sidewalks. What about linear street parking spaces, if those are to be converted for creating urban parks and whatnot. Real estate prices would not be a fitting approximation for the lost foregone best benefit in these situations, it seems to me.
I have not found any alternatives in the literature for taking into account the opportunity costs of open or public space. Do you have any insights on this matter ? Any literature on geographic economics or urban economics modelling that deals differently with this ?
Many thanks for any contribution
I need materials on the text instituting the CBA as well as its importance in the teaching/learning process. I want to come up with an academic paper comprising information on the text instituting the CBA as well as the importance of CBA in the teaching/learning process. The level of study here does not matter, but the information above. Thank you in advance for your help.
I would like to examine the level of TNF-alpha, IL-6, Il-1beta, Il-8 in the supernatant of human adipose tissue after various periods of storage in various preservative fluids. Is it necessary to prepare a sample before the detection? So far, I have been trying to harvest a supernatant and store it in -80 degrees after spinning it (from tissue contamination), or not. In both cases, the detection was placed at the lower threshold; everything shows that it should be much higher. I have used a Human Inflammatory Cytokine Cytometric Bead Array (CBA) - I Kit (RUO) Bioscience. What can I do to get some more distinct results?
Intelligent transportation systems provide many advantages as part of our daily lives. One of the most common applications of these current and increasingly widespread systems in our cities is intelligent junction control. The scope of the intelligent junction control concept which includes different approaches and algorithms, is quite wide. It is known that it needs realistic and objective technical knowledge to guide decision makers correctly. In this sense, what do you think the definition of intelligent intersection should include? Is a high-cost intersection control system with a lot of equipment always necessary? Or are the lower cost solutions that enable multi-plan control by only increasing the number of control programs? What should be the threshold or the transition point for the preference? Is it sufficient to make only cost-benefit analysis? To what extent should social benefits be taken into account for feasibility analysis? Sharing your views on this issue can be beneficial to many researchers and interested parties and can contribute to the spread of sustainable transportation (traffic management) systems.
Dear RG members
I am starting to teach CBA course for PhD students at my university. Could anyone recommend me what case study may be the best to show/teach to PhD students for CBA?
The case should be illustrative and implications should be easy to grasp to students, and it should be Scientific Paper or Report done by international organizations like WorldBank, ADB, or FAO etc.
Thank you for your support
I am interested about application of LCA (Lifecycle Assessment) and cost benefits analyses to revise the environmental policies and associated taxes.
(https://www.advocata.org/commentary-archives/2018/9/23/the-cost-of-being-a-sri-lankan-woman). The content in this article may not 100% accurate, however, by experience I know the basics points mentioned here is true.
"The taxes on baby diapers and sanitary napkins are high as 71.2% in Sri Lanka (It is only 12% GST in India). According to SAARC (South Asian ...) Chamber Women Entrepreneurs Council, out of 5.2 million menstruating women, only 30% can afford sanitary napkins in Sri Lanka.
These taxes are not only affecting a women's cost of living but also has negative effects on girl's education and menstrual hygiene."
Hence, I wonder the following points;
A. LCA and cost benefit analyses and Environmental policy making (If you have some case studies please share).
B. How to dispose baby diapers and sanitary napkins? (Is controlled incineration the only solution?)
C. How developing countries manage the issue (if there is any case study).
D. Readers may add any other interesting information or questions.
We have a problem with the fcs files of CBA generated by the "Attune Nxt" cytometer, these files can not be detected by "FCAP" software because these files are in version 3.0.
We need a software that converts cytometry files fcs version 3.0 to 2.0. Anyone who can help me with the conversion of the files?
We could consider this a collaboration.
I need to know the tangible values of thesis in higher education. How can I calculate the effectiveness or benefits of passing "thesis" in comparison to its costs?
It is always come to my mind that how can I assess the pros and cons of thesis (dissertation) preparation in terms of monetary scale?
Would you please let me know about related literature in this regards?
As Miyawaki method is presently getting popularity in various afforestation programmes we also
wish to try it on some parts of barren hills of Udaipur (Rajasthan). But I have gone through some literature and I found some contradiction on significance of the method. Some scientist are saying it is good while others are telling it is not a option for preparing natural forest or it is not cost effective.
So it will be very good for mother Earth if intellectuals, scientist and forester come for discussing this topic and showing the importance of the method. It may be a very good method for combating climate change and restoring degraded areas in general.
Hello everyone, so I'm trying to create a least cost-benefit map and factors for least cost-benefit are very varied like slope, elevations, region vegetations and etc. I must say I'm very confused between these varied factors and I just want to make sure that I choose the correct and suitable factor in my map. although I want to create several maps of least cost-benefit but i want to ask you: what is the best factor for least cost-benefit for reaching a site to another in a region like southeast Iran?
if you are unfamiliar with the region and topography of southeast Iran, I must say that it's just like the most regions in Baluchistan of Pakistan with low hills in east of the region and high mountains in west. the vegetations of regions is also similar.
so if anyone could help me, i will be so grateful. thank you.
While there are increasing support for floating solar panels over water bodies, research on floating photovoltaic power plant assessments in the field of sustainable energy technologies and assessments are studying the negative and positive side effects, including environmental and techno-economic impacts of floating solar panel projects?
The First Global Floating Solar Conference recently stated that: floatovoltaics or floating PV (FPV) preserves agricultural farmland as it reduces the land footprint for ground-mounted solar projects, while the floating solar economic surface transformation (EST) can be defined as the $ income generated from previously unused water surface now tranformed by floating solar to generate income from power and other sources such as agronomic income from saved agricultural land (Prinsloo, 2021).
What are positive impacts of putting floating solar panels over a water body like the ocean or irrigation dams, rivers, canals (including scientific references) ?
Looking for any tips to measure phospho STAT3 in the proteins extracted from Trizol.
I have very limited sample size ( human synovial tissue biopsy) and priority is to mesure gene expression. However I would lkie to also to measure pSTAT3. MAy protocols available online to extract proteins from Trizol and also litereture shows that phospho proteins can be mesured by WB. Unfortunatelly for my sampoe size the WB is not senitive nough and I am looking into using ELISA or CBA assay.
I will be using Aceton precipitation of protein from Trizol ( after RNA and DNA extractions) following the protocol of
Direct-zol DNA/RNA Miniprep kit and I was wondering what I could use to resuspend the pellet?
Will the pellet resuspend in the diluition buffer supplied in the ELISA kit? Many people on Reseachgate etc.. complained that pellets don't resuspend well and I am aware that not all buffers will be suitable for ELISA ( some may block abs binding).
Can anyone comment/recommend a potential way of preparing the proteins for phospho ELISA?
Thank you Agata
Recently I've been looking T CD4 subset and the CBA kit of BD Th1/Th2/Th17 hasn't been enough for my needs, I want to investigante another subsets such as Th9/Thf. Biolegends has this similar beads assay to evaluate cytokine with more cytokine such as IL-9 and IL-21, but I don't have experience with this kit and my research colleges never used this kit. Does anyone has a experience with this kit? Does it perform well with ex vivo splenocyte supernatant?
Disaster Risk Recovery/ Mitigation efforts are one of the most spent sectors worldwide as large number of lives and infrastructures are ravaged worldwide by recurring hazards. Since recovery efforts are blended with multitude of factors including enthusiasm, awareness, dedications and helping hands(expertise, funds and endorsement of policies) it is not easy to interpret in terms of economy. Hence, what are the practices/methodologies worldwide to interpret D.R.R efforts in terms of cost benefit analysis?

Friends and seniors:
We are planning to conduct a community based Controlled Before & After (CBA) study and our interventions will include adolescents [both left behind (e.g., adolescents whose parents have migrated overeseas] and non-left behind] of our study areas. However, we really like to focus our outcomes on left behind adolescents so the sample size calculation should consider this.
1. Power : 80%; Sig Level (2 tailed): 0.05; effect size (estimated): 0.3 (30%) and SD of the outcome (mental health related tool): not known yet as there are not any interventions among left behind adolescents. In this case, shall we assume ± 3 SD (thumb rule)?
2. What would be the sample size for intervention and control area?
looking forward your reply.
Barind area of Bangladesh is a water crisis area. The problems acute day by day. Integrated Water Resource Management (IWRM) project has been undertaken. We are working as follow the guideline of GWP and trying to get solution implementing appropriate context specific model.
"Boro rice" is most water consuming rice. We are motivating farmer to shift that crops with less water consuming crops e.g: maize, wheat, tomato etc. Farmers also adopted it.
Beside the many intervention we also installed water efficient technology like AWD, drip irrigation etc.
We calculated that, replacing boro cultivation in 1 hectare of land with wheat, tomato, and fruits saves annually 1.6 million cubic metre of equivalent to 100’000 people’s annual domestic water need.
Interventions in agriculture have a much higher effect compared to the interventions above at HH level or the MAR system where there we talk about thousands of m3, while the agriculture related interventions we talk about millions of m3.
A question is that, Is MAR needed for establishing true IWRM? How are the impact? Though a little contribution, why we invest a big budget to MAR compared to cost benefit analysis of agricultural intervention?
In two programs A and B run by state government : Program A health care cost INR 2500000,patient and family cost INR 150000, cost in other sectors INR 500000; Program B health care cost INR 1500000,patient and family cost INR 75000, cost in other sectors INR 300000. Following net gains were achieved: Health 400 years of life gained, utility 290 QALYs gained, Willingness to pay INR 100000000, Health care saving 2500000, Saving to patients and families 100000, saving to other sectors 200000? calculate incremental cost effectiveness ratio using health benefit as measure of outcome? calculate incremental cost effectiveness ratio for cost utility analysis? calculate values of net benefit for cost benefit analysis?

I'm doing Energy Audit study for a distribution utility, and there are two studies one for energy efficiency improvement and the second focuses on the economic analysis, I have searched and found that mainly the energy audit is done for building or any energy dependent place, but for an electric distribution substation, the economic study is not clear for me, if anyone can help understand it briefly or if there are articles supporting the study, please do share them.
Hi all, I searched for Cost and Benefit Analysis of Exploiting minerals in some place in the whole world, but I got nothing. Also, I did not see any publication about applying CBA method for extractive industry. It seems like there is no publication about this topic?
I am looking into literature that explains which incentives a country has to introduce policy assessment tools for legislation enacted by Congress or the Parliament. For example, there is a vast literature on government accountability that explains why governments would adopt these tools on secondary regulation (oversight, address delegation problems, etc.). However, for the case of primary legislation it is not as clear to me what justifies it from a Law and Economics or Political Economy perspective, or even just legal.

Namibia is one of the countries in sub-Sahara Africa with high HIV/AIDS prevalance, HIV/AIDS consumes most of the health expenditure which is currently mainly funded by donors, and the donors are withdrawing for the government to take full financing. I am thinking of an intervention on the youths in schools, if effective to be extended to communities. The intervention is continuous screening and testing of HIV in youths, by knowing their status can empower them to take full responsibility on protection against HIV and also those diagnosed can be supported and properly managed early. A main limitation to this can be fear of stigmatization but yet creating awareness with this intervention can also help fight stigma in HIV.
i would like your ideas in how i can do a cost analysis for this intervention and its feasibility as a cost-effective study/intervention.
I plan on conducting, as above, a cost-benefit analysis of a proposed no-fee irrigation water policy. I imagine doing this as a case study on one irrigation system, but is it doable? What kind of data is required?

An increasing number of listed firms are using XBRL in the reporting process.Would this complicate the audit approaches and audit implications?
Also, in the auditees' perspectives, what is the costs-benefits of using XBRL? Please share your views, experiences and thoughts, thanks
Since 2004, the Securities and Exchange Commission (SEC) expects firms to use eXtensible Business Reporting Language (XBRL) to file their reports. This helps tag a firm’s financial information using a computer readable and searchable engine. Investors are demanding assurance on the tagging process but the Public Company Accounting Oversight Board (PCAOB) has yet to issue a guidance on attesting the engagements regarding XBRL financial information furnished under the SEC’s current voluntary filer program, which relies on the auditor agreeing a paper version of the XBRL-related documents to the information in the official EDGAR filing. This approach is deemed adequate for the current paper-oriented reporting paradigm but once the filing in XBRL becomes mandatory, this will affect the way financial and non-financial data are reported, used and attested. The current audit focus on reconciling only the XBRL output with the paper submissions may not completely address this paradigm shift and may add costs to the rising audit costs and delays of issuing audit opinions.
One of the crucial aspects related to infrastructure regulation is, which and how projects are socially relevant? or how those projects must be ranked under society interest?. Indeed, for decades, the most interesting tool used is the cost benefits analysis, or the economic socio-economics studies on those, incorporating externalities and shadow prices for some social benefits or costs. However, it is generally assumed that the baseline of those analysis is a pure competitive and well known equilibrium price as a point of departure. Ethics on assumptions and not well defined alternatives for example are not always defined as explicit contents on CB analysis reports and evaluation practices.
All decisions taken by rulers have political consequences which has a cost For instance going to war or joining an alliance for war ( Pakistan's decision to join the global war on terror in 2001) was a political decision. How can we measure its, Political cost and benefits? In short what can be operational definition of Political -Benefit Analysis.
For the purpose of analysis of this decision to join the war on terror by Pakistan ,Technically this decision can be called Political Cost-Benefit Analysis?

as carbon targets indicate for developed countries there needs to be applied a common retrofit solution on a national scale in order to cut down emissions of greenhouse gases. so how construction firms can prescribe ecoefficiency as a rule to massive retrofits in domestic market? is a cost benefit analysis fully capable to incept transition or is there something else more appropriate?
Related to a research project, I would like to use a regional econometric input-output (EC+IO) model in order to value economic impacts coming from the implementation of offshore wind project in Brittany (Brittany is a French region). A standard input-output model values only the gross effects (in production and employment for instance), but not the net effect explained by the reduction in household consumption coming from the increase in taxation required to finance the offshore wind project. A regional EC+IO model enables to overcome this limit inherent to the standard input-output model.
I know that there are different types of EC+IO models (see for instance the article of Rey 1998 published in International Regional Science Review). But, there may be a book explaining and summarizing the different techniques required to implement a EC+IO model (for instance econometric techniques specific for regional models, …).
I have read several recent papers concerning ecological restoration and remediation of polluted areas but surprisingly it is often used a BCA in the average project. I understand that meaningful costs and benefits are mandatory to carry out ecological restoration or polluted areas remediation but there are problems linked to the purely economic conception of BCA methodology -such as the difficulty to evaluate social benefits or costs. In fact, I consider that it would be more convenient to use different methodologies –like SWOT analysis plus BCA - to make decisions and plan projects.
So, the points of this post are:
1) Do you believe that only BCA should be applied? What are the advantages of using only this methodology?
2) Do you think SWOT analysis along with BCA should be the methodology considered? What advantages are associated?
3) Is there another available methodological approach? Should there be a mix of methodologies to cope with the planning and maintenance issues of ecological restoration?
Thanks in advance.
Multi-objective optimization can be used in sewer system rehabilitation. Many particular aspects may be modeled and optimized, like rehabilitation costs, reduction of costs of transport and treatment (reduction of Infiltration/Inflow rates), useful life of the components, rehabilitation techniques options, and structural condition of existing/rehabilitated sewer pipes, between others. What are the current possible approaches, the possible objective functions, and the predictable development in this area a short term?
I am currently studying the LHC and other experimental facilities in physics, including pure science or applied, e.g. for cancer therapy, and testing a social cost-benefit analysis model taylored to infrastructures providing research services. I am interested to know if other have seen similar work around. Our methodological paper is: Massimo FLORIO & Emanuela SIRTORI, 2014.

I am working on a cost effectiveness analysis linking with survival of patients with cancer. The survival part of the analysis is necessary to estimate the "number of life-years gained". To find this quantity I need to calculate the area under the survival curve. In this specific context of long term survival of cancer patient, i need to choose the parametric function of Gompertz which fit the survival in the best way. I'm working on stata software and I would to know if anyone has already done a Gompertz model in STATA, and how to calculate the area under the curve which is the integration of the Gompertz function. Thank you so much for you suggestions.

As we have seen, nowadays BIM technology is wildly used in the AEC industry. There are numbers of papers talking about how to apply BIM in cost-benefit analysis, energy simulation, sustainability evaluation, life cycle assessment and so on.
Most of these processes require manual data input to the model while others might use kind of sensor to generate data.
Therefore, I wonder how accurate of the current data input methods for BIM simulation or analysis, and how to make sure the results are turn out to be reliable?

Does anyone know of any similar studies (in whatever field)?
We are interesting in using the costs-benefits evaluation of agricultural productivity of the experimental trial (using biochar-based treatments and the control) to evaluate how smallholders deciding to use these treatments along with all other agricultural inputs (costs) and outputs (benefits) would impact their livelihoods (net benefits/net revenue/net profit)?
In our cost-benefits evaluation, we monetized every transactions so that we could calculate the net benefits to net cost ratio to determine the optimal productivity and treatment choice that smallholders could mostly likely prefer.
The main assumption here is that smallholders rely on farming for their livelihoods, as a result, the total net benefits (what smallholders generate from their farming activities each growing season) should be </= to total net costs (all inputs).
During this study, we calculated agricultural inputs (costs) against outputs (benefits). We also monetized all factors that were freely contributed to the project by the farmers as benefits, since we did not pay for it.
The total amount spent on treatment were spread out against each treatment (as the treatments were used as the inputs and output variables). We also spread all the potential benefits across each treatment in monetary form.
To determine the optimal treatment choice that smallholders might most likely preferred, we computed the net benefits to total cost ratio. The ratio which is dimensionless, was used as the decision variable. That is, the higher the net benefit to total cost ratio per treatment productivity, the most prefer would that treatment be used by smallholders. The underlying idea is that the total net benefit should exceed total cost.
Total harvest per treatment were also monetized and the net revenue factor in the calculation as benefits.
Inputs (costs) is a sum of = [manure ($/kg) + Land ($) + irrigation ($) + seeds ($/kg), + pyrolysis system ($) + inorg. fert. ($/kg) + transportation ($/trip) + labor ($/person/day) + lunch ($/person/day)]
Some factors in the benefit categories that were given/donated by farmers that we did not pay directly were used as benefits (saving farmers from the expense). These included feedstock and water from the dug well used for irrigation.
Outputs (Benefits) is a sum of = [Rice straw ($/kg) + rice husk ($/kg) + tools ($/day) + savings of pyrolysis system over time ($ X 2yrs) + net renevue ($) + water ($/gal/day)].
Net Benefit = Total Benefits - Total Costs
Net Benefits to Total Cost Ratio = Total Benefits / Total Costs
One other factor was sustainability. How would you monetized that if you were interested in that aspect? What have we left out?
The net revenue portion was calculated separately using crop yield data (kg) and price kg and subtracting the cost of revenue and operating costs. Laos has 0% for domestic vegetable growers or rural smallholders as the country is encouraging agricultural productivity.
