Research and Cost Benefit Analysis  Paper

Infrastructure, education, environmental protection, and health care are examples of goods and services that in many circumstances are not produced by competitive private companies. Instead, decision making regarding investments and regulations is often made by politicians or public sector officials. For these decisions to be consistent, rational, and increase welfare, a systematic approach to evaluating policy proposals is necessary. Cost-benefit analysis is such a tool to guide decision making in evaluation of public projects and regulations. Cost-benefit analysis is a procedure where all the relevant consequences associated with a policy are converted into a monetary metric. In that sense, it can be thought of as a scale of balance, where the policy is said to increase welfare if the benefits outweigh the costs. Cost-benefit analysis of a proposed policy may be structured along the following lines:Research and Cost Benefit Analysis Paper

  1. Identify the relevant population of the project. For a cost-benefit analysis of a single individual or for a firm, this is not a problem. But in a societal cost-benefit analysis, we need to consider how to define society. A common approach is to consider the whole country as the relevant population. This is reasonable given that most public policies are financed at the national level. Another approach is to conduct a cost-benefit analysis specifying costs and benefits using different definitions of the relevant population—for example, including benefits and costs of a neighboring country in the analysis.
  2. Specify all the relevant benefits and costs associated with the policy. The aim with a cost-benefit analysis is to include all relevant costs and benefits with a policy. Based on the definition of the population (Step 1), every aspect that individuals in this population count as a benefit or a cost should be included in the analysis. For some benefits and costs of a policy, this may be an easy task—for example, 2,000 hours of labor input are required next year to build a road. But there are also more difficult phases in this step of a cost-benefit analysis; some examples include (a) a new infrastructure investment may have ecological consequences that are difficult to estimate and (b) regulating speed limits in a major city may have beneficial health effects due to decreases in small hazardous particles. For the economist or analyst, this step often consists of asking the right questions and gathering the necessary information from the literature, professionals, or both.
  3. Translate all the benefits and costs into a monetary metric. A cost-benefit analysis requires that the different consequences are expressed in an identical metric. For simplicity, we use a monetary metric ($ or €, etc.). Consider the example of an investment in a new road. The costs for the labor input can be valued by the wages (plus social fees, etc.), and the use of equipment may be estimated by the machine-hour cost. For benefits of, for example, increased road safety, decreased travel time, and decreased pollution level, there are no market prices to use; instead, weights and estimates are necessary to translate these benefits into a monetary metric. If this would not be possible with all relevant consequences, they should at least be included as qualitative terms in the evaluation. In the Valuation of Non market Goods section, giving non market goods a monetary estimate is discussed.
  4. If benefits and costs arise at different times, convert them into present value using an appropriate social discount rate. Most people prefer a benefit today to a benefit in one year. There are several reasons for this, one being that no one knows for sure whether he or she will be alive in a year. Another reason may be that, over a longer time horizon, people expect their incomes to increase in the future.Research and Cost Benefit Analysis Paper If an extra dollar has a larger utility benefit to a less rich individual, that individual would prefer to consume when he or she has less money (today) rather than when he or she has more (e.g., in 5 years). Also, from an opportunity-cost approach, $100 that is not consumed today can be invested in a bond, and in a year from now, it may be worth $105, implying higher consumption in one year. In a cost-benefit analysis, economists therefore (generally) do not treat benefits and costs that occur at different times as equal; rather, they translate all benefits and costs into a present value. Choosing an appropriate social discount rate is, however, a complicated task and will often have major effects on the results of the evaluation. In the Discounting section, this is discussed in more detail.
  5. Compare the net present value of benefits and costs. When the present value of benefits (PVB) and costs (PVC) has been calculated, what remains is to calculate the net present value (NPV). The policy is said to increase social welfare if the net present value is positive—that is, PVB- PVC> 0. It is also common to express the comparison as the benefit-cost ratio—that is, PVB / PVC, which gives the relative return of the investment. If the ratio is greater than 1, the policy increases social welfare.
  6. Perform a sensitivity analysis to see how uncertain the benefit-cost calculation may be and give a policy recommendation. A cost-benefit analysis will have several uncertainties regarding the outcome. It is most often not reasonable to show only one point estimate of the evaluation. There are often uncertainties regarding both parameter values (such as the monetary estimates of, e.g., increased safety or environmental pollution) and more technical issues, such as the economic lifetime of a new road, which is the period during which it retains its function. These uncertainties need to be explicitly modeled. The final step in a cost-benefit analysis is to give a policy recommendation based on the result of the evaluation as well as the uncertainties associated with the result.Research and Cost Benefit Analysis Paper
What Do We Mean by Social Welfare?

The aim with a cost-benefit analysis is to evaluate the welfare effect of a policy. This requires a definition of what is meant by social welfare in an economic framework. The meaning of a welfare improvement is, in its most restricted view, formulated in the Pareto criterion. The Pareto criterion states that a policy that makes at least one individual better off without making any other individual worse off is a Pareto-efficient improvement and increases welfare. However, the Pareto criterion is generally useless as a definition for welfare improvements in a real-world application, because more or less all policies make at least someone worse off. It may also be criticized on ethical grounds; consider a vaccine that would save 1 million lives in sub-Saharan Africa but required a €1 tax on someone (a non altruistic individual) in Europe or the United States. According to the Pareto criterion, this policy could not be said to increase welfare, but this conclusion would violate the moral values of most individuals.

As a development to the Pareto criterion, the Kaldor-Hicks criterion was formulated, and it may be seen as the foundation of practical cost-benefit analysis. The Kaldor-Hicks criterion is less restrictive than the Pareto criterion and may be interpreted such that a policy is considered to increase welfare if the winners from a policy are made so much better off that they can fully (hypothetically) compensate the losers and still gain from the policy (potential Pareto improvement). This implies that every Pareto improvement is a Kaldor-Hicks improvement, but the reverse is not necessarily true. The compensation from the winners to the losers is a hypothetical test, and the compensation does not need to be enforced in reality (which distinguishes it from the Pareto criterion). In the example above, the vaccine to save 1 million lives would pass the Kaldor-Hicks criterion, if those who were saved would be hypothetically willing to compensate the European taxpayer with a payment of at least €1. Cost-benefit analysis is a test of the Kaldor-Hicks criterion, translating all the benefits and the costs into a monetary metric. The Kaldor-Hicks criterion also implies that we need to collect information only on aggregate benefits and costs of a policy; we do not need to bother ourselves determining which individuals are actually winning or losing from a policy.Research and Cost Benefit Analysis Paper

Valuing Benefits and Costs

Performing a cost-benefit analysis of a policy requires that all benefits and costs of the policy be summed up in monetary terms. There are two principal ways of measuring the sum of benefits in a cost-benefit analysis: willingness to pay (WTP) and willingness to accept (WTA). Both WTP and WTA are meant to value how much a certain policy is worth to an individual in monetary terms. The WTP of a policy may be characterized as an individual’s maximum willingness to pay, such that he or she is indifferent to whether the policy is implemented— that is, if it is implemented, utility is the same after the policy as before the policy. The WTA of a policy may instead be characterized as the lowest monetary sum that an individual accepts instead of having the investment implemented—that is, utility is the same when receiving the money as it would have been if the investment had been implemented. WTP and WTA for a policy are expected to differ (WTP < WTA) because of the income effect. Robert D. Willig (1976) shows, using plausible assumptions, that WTP and WTA should not differ from each other by more than a few percentage points. But a lot of research has documented that WTP and WTA usually differ a lot for the same policy, with WTA being significantly higher than WTP. Several hypotheses have been put forward trying to explain this discrepancy, one frequent hypothesis being the existence of an endowment effect (Kahneman, Knetsch, & Thaler, 1990). An endowment effect states that individuals value a good significantly more once they own it, which would create a gap between WTP and WTA for an identical good. In several circumstances, it is often more problematic to estimate WTA for a good, especially in valuation of nonmarket goods, implying that it is more common to use the concept of WTP in cost-benefit analyses.

The cost of a certain policy is based on the opportunity cost concept—that is, the value of the best alternative option that the resources could be devoted to instead. The opportunity cost is derived based on companies’ marginal cost curve—that is, the cost that is associated with increasing output with one unit. This should not be equalized to accounting costs, which do not necessarily tell us the economic cost of an activity. As an example, going to a 2-year MBA program has some direct costs (accounting costs), such as tuition fees, books, and travel costs to attend lectures, but also indirect costs, such as the money that one could earn in a job if not attending the MBA program. The economic cost of an activity is the sum of direct and indirect costs.

Valuation of Market Goods

To estimate benefits and costs of a policy, the natural starting point is to examine whether market prices exist that may be used. If the market is characterized by perfect competition, or a reasonable approximation of perfect competition, and no external effects exist, the market price can give us information about the willingness to pay for a marginal change of a good. For example, if we need to use production factor X for a certain investment and our demand for X will not affect the market price, we can use the market price as a cost measure. The total cost of the production factor in the cost-benefit analysis is, then, the market price multiplied by the number of units used. However, if the policy will also affect the market equilibrium, we cannot simply use the market price in our analysis. Figure 27.1 shows the difference.Research and Cost Benefit Analysis Paper

Initial market equilibrium is at price P0 and quantity Q0. Imagine that a new policy will lead to a decrease in the market price to P1, which increases quantity consumed to Q1. The total benefits of this policy include the increased consumer surplus for the original consumers (rectangular area P0P,AC) as well as the benefit of the new consumers (triangle area ABC). Hence, the total benefit may be represented by the area P0P,AB, which shows that when a policy has a non marginal effect on the market price, we cannot simply use the policy market price in a cost-benefit analysis.

Cost benefit analysis: What is it?

A cost benefit analysis (also known as a benefit cost analysis) is a process by which organizations can analyze decisions, systems or projects, or determine a value for intangibles. The model is built by identifying the benefits of an action as well as the associated costs, and subtracting the costs from benefits. When completed, a cost benefit analysis will yield concrete results that can be used to develop reasonable conclusions around the feasibility and/or advisability of a decision or situation.Research and Cost Benefit Analysis Paper

Why Use Cost Benefit Analysis?
Organizations rely on cost benefit analysis to support decision making because it provides an agnostic, evidence-based view of the issue being evaluated—without the influences of opinion, politics, or bias. By providing an unclouded view of the consequences of a decision, cost benefit analysis is an invaluable tool in developing business strategy, evaluating a new hire, or making resource allocation or purchase decisions.

Origins of Cost Benefit Analysis
The earliest evidence of the use of cost benefit analysis in business is associated with a French engineer, Jules Dupuit, who was also a self-taught economist. In the mid-19th century, Dupuit used basic concepts of what later became known as cost benefit analysis in determining tolls for a bridge project on which he was working. Dupuit outlined the principles of his evaluation process in an article written in 1848, and the process was further refined and popularized in the late 1800s by British economist Alfred Marshall, author of the landmark text, Principles of Economics (1890).Research and Cost Benefit Analysis Paper

Cost-benefit analysis (CBA) is a technique used to compare the total costs of a program me/project with its benefits, using a common metric (most commonly monetary units). This enables the calculation of the net cost or benefit associated with the program-me.

As a technique, it is used most often at the start of a program-me or project when different options or courses of action are being appraised and compared, as an option for choosing the best approach. It can also be used, however, to evaluate the overall impact of a program-me in quantifiable and monetized terms.

CBA adds up the total costs of a program me or activity and compares it against its total benefits. The technique assumes that a monetary value can be placed on all the costs and benefits of a program-me, including tangible and intangible returns to other people and organizations in addition to those immediately impacted. As such, a major advantage of cost-benefit analysis lies in forcing people to explicitly and systematically consider the various factors which should influence strategic choice.Research and Cost Benefit Analysis Paper

Decisions are made through CBA by comparing the net present value (NPV) of the program-me or project’s costs with the net present value of its benefits. Decisions are based on whether there is a net benefit or cost to the approach, i.e. total benefits less total costs. Costs and benefits that occur in the future have less weight attached to them in a cost-benefit analysis. To account for this, it is necessary to ‘discount or reduce the value of future costs or benefits to place them on a par with costs and benefits incurred today. The ‘discount rate will vary depending on the sector or industry, but public sector activity generally uses a discount rate of 5-6%. The sum of the discounted benefits of an option minus the sum of the discounted costs, all discounted to the same base date, is the ‘net present value of the option.

Programmatic economic analyses can provide important information on the relative costs and benefits of an intervention, program, or policy. Such information is often demanded by decision makers to help assess the relative value between a set of alternative options. Types of economic analyses include programmatic cost estimation, cost-of-illness studies, cost-effectiveness analyses, benefit-cost analyses, and return on investment analyses, and several others.Research and Cost Benefit Analysis Paper

NORC is a leader in the development of practical guidelines for government policy makers in the use of economic analyses within the Department of Health and Human Services. On behalf of the Assistant Secretary for Planning and Evaluation of Health and Human Services, NORC developed concrete guidance on how to understand and use decision-analytic modeling information to inform governmental decision-making. This report (which can be accessed  provides an in depth discussion of the approaches to economic evaluation, the valuation of health benefits, modelling methodology and differences between study designs, and best practices for sound economic modelling, and information regarding sensitivity analyses.(1) In a subsequent and forthcoming document, NORC partnered with researchers from Harvard University and the research firm Industrial Economics, Inc. to develop guidance on the evaluation of potential cost of illness estimates for use in federal regulatory benefit-cost analysis. Finally, NORC has conducted advisory work for the Patient Centered Outcomes Research institute (PCORI) on the use of value of information approaches (an advanced extension of cost-effectiveness analyses) to set research priorities.(2)

NORC also offers hands on experience in the application of cost-effectiveness and benefit-cost analyses to inform public health policy. In the area of cost-effectiveness, NORC developed the cost-effectiveness evidence in support of CDC’s ‘Baby Boomer’ hepatitis C testing recommendation. This work was featured as an early release in Annals of Internal Medicine, and led directly to a change in CDC testing guidelines for hepatitis C.(3) NORC researchers have utilized state of the art cost-effectiveness methods such as probabilistic sensitivity analyses, cost-effectiveness acceptability curves, incremental net benefit outcomes, cost-effectiveness estimates by payer, and expected value of perfect information calculations.(4)Research and Cost Benefit Analysis Paper

This research note republishes the foreword from a special symposium issue of the UC Irvine Law Review on cost-benefit analysis. The issue was published in conjunction with a conference that asked scholars and practitioners to rethink cost-benefit analysis in the context of the Financial Crisis, which raised old questions anew about regulation and quantification. As discussed in the foreword, the symposium issue contains three articles that analyze and evaluate cost-benefit analysis from distinctive perspectives.

Research note on The Costs and Benefits of Cost-Benefit Analysis by Adam Sechooler

Cost-benefit analysis (CBA) is a controversial yet fundamental aspect of the American regulatory state.[1] Despite its importance, many commentators have argued that the costs and benefits of CBA have not been adequately weighed.[2] Concerns about CBA are all the more salient following the Financial Crisis of 2007–‍2008 and the Great Recession. In the aftermath of what is generally considered the most severe financial crisis and economic contraction since the Great Depression,[3] scholars and other experts continue to rethink the role of regulation and the tools available to regulators. Although the debate continues about whether we have too much or too little regulation, the Financial Crisis precipitated a historically significant expansion of regulation. The Dodd-Frank Wall Street Reform and Consumer Protection Act, signed into law in 2010, is often considered the most far-reaching financial regulatory reform since the New Deal.[4] The Act affects virtually every part of the U.S. financial services industry and created several new regulatory bodies, including the Consumer Financial Protection Bureau, a new independent agency.[5]Research and Cost Benefit Analysis Paper

In addition to questions about the extent of regulation, the Financial Crisis also raised crucial concerns about how we regulate. Some of these concerns are rooted in a renewed skepticism about the assumptions that underlie complex quantitative models. Amar Bhidé, for example, critiques “top-down measures”—including those of Dodd-Frank—because risk “can be quantified only to a degree.”[6] Just as the quantitative models behind complex financial products depended on assumptions that turned out to be faulty, Bhidé cautions against theories of regulation that assume “not just rationality in the ordinary sense of the word, but also universal omniscience.”[7] Instead, Bhidé argues for a decentralized approach to regulation and an approach to finance that would take “into account unquantifiable uncertainties and the uniqueness of individual circumstances.”[8]

The underlying epistemological concerns about the limits of quantification that some commentators raised in response to the Financial Crisis are also relevant to CBA. As Amy Sinden’s article in this issue makes clear, CBA “is not a monolith.”[9] Some forms of CBA are more formal than others.[10] Nonetheless, CBA is typically thought of as a fundamentally quantitative methodology. As Arden Rowell writes,

Modern regulatory cost-benefit analysis is a systemized method of comparing the expected advantages and disadvantages of proposed policies. The method relies on a process of monetization that converts nonmonetary costs and benefits into a common metric—money—by using market- and preference-based studies of people’s willingness to pay money to acquire benefits or avoid costs.[11]Research and Cost Benefit Analysis Paper

Thus, while the exact definition of CBA may be debated, it is typically thought of as a process that aggregates the costs and benefits of a regulation and, where necessary, converts those costs and benefits into a common quantitative metric. CBA may therefore be susceptible to the critiques of quantification discussed above. For example, Frank Ackerman and Lisa Heinzerling critique CBA because it requires quantifying “priceless” values, like human health and safety or the ethical principles underlying environmental protection.[12] Instead, Ackerman and Heinzerling argue for a “holistic approach, where costs as a whole (usually monetary) and benefits as a whole (often largely nonmonetary) are considered together—but are not forced to be expressed in the same units.”[13]

Of course, CBA has many defenders and advocates.[14] Some scholars have emphasized the importance of CBA in enhancing efficiency[15] or even rationality.[16] Others have argued that CBA can strengthen democratic accountability because it makes agency decision making more transparent to both the public and elected officials and insulates “agencies from powerful political pressures.”[17]

Recent scholarship has also attempted to reframe the debate by moving it from an absolutist “for or against” to a more contextual “when and how.” Scholars have argued, for example, that CBA’s practitioners should abandon a narrow focus on economic efficiency and instead focus more broadly on maximizing well-being. In short, cost-benefit analysis should be redubbed well-being analysis (WBA) and use the metric of happiness, broadly defined, rather than money.[18] Because it seeks to directly measure the effects of regulations on people’s well-being, WBA may avoid the “distortions created by using money as a proxy for people’s quality of life.”[19] In another effort to reframe the debate, Richard Revesz and Michael Livermore argue that what is often thought of as CBA’s antiregulatory bias is “historical rather than conceptual.”[20] According to Revesz and Livermore, reform can remove CBA’s “systematic antiregulatory biases.”[21] With the addition of “distributional analyses of the cumulative effects of regulation,” a reformed CBA could lead to a fairer and more efficient administrative state.[22] In a still more recent effort to recast CBA, Robert Ahdieh writes that CBA in financial regulation should take on a broader, less quantitative but equally rigorous form.[23] Ahdieh also emphasizes the importance of “embracing a discourse of cost-benefit analysis focused on the diversity of functions it may serve and the varied forms it may take.”[24] Ahdieh points to four factors—the source of law, the nature of the responsible agency, the nature of the problem, and the variables to be analyzed—that should be weighed in determining whether or how CBA should be used in a given situation.[25]Research and Cost Benefit Analysis Paper

Regardless of the current state of the academic debate surrounding CBA or the renewed skepticism about quantification following the Financial Crisis, it is unlikely that the importance of CBA will diminish anytime soon. CBA is required by numerous statutes and has been embraced by each successive presidential administration, both Democratic and Republican, since President Reagan mandated CBA by executive order in 1981.[26] Recent events suggest, if anything, that CBA is becoming more influential and perhaps more quantitative. The proposed Independent Regulatory Analysis Act,[27] which is strongly opposed by many environmental and public interest groups[28] and strongly favored by many business groups,[29] would allow the President to require independent agencies, including the newly formed Consumer Financial Protection Bureau,[30] to conduct CBA even when it is not otherwise mandated by statute.[31] Moreover, Arden Rowell writes in this issue that a new executive order under President Obama exhibits “a heightened emphasis on the importance of quantification over prior cost-benefit orders,” according to a number of commentators.[32] Recent court decisions also affirm the continued importance of CBA. Perhaps most notably, in Business Roundtable,[33] the District of Columbia Circuit vacated a Securities and Exchange Commission (SEC) rule because, according to the court, the SEC failed to adequately weigh the costs and benefits of the rule as a formerly obscure section of the National Securities Market Improvement Act required.[34]

An understanding of the costs and benefits of CBA is all the more important given the expansion of rulemaking under Dodd-Frank. It is still unclear just how pervasive CBA will be or what form of CBA will be adopted in the context of financial regulation. Some commentators have argued that financial regulation is particularly well suited to CBA, while others have argued precisely the opposite. For example, John Coates offers a series of case studies and concludes that while some forms of CBA may be useful, quantitative CBA is “not currently feasible with any degree of precision and reliability for representative types of financial regulation.”[35] Instead, Coates emphasizes the centrality and inescapability of expert judgment.[36] In the context of financial regulation, according to Coates, CBA is therefore more likely to “camouflage” underlying motivations than to inform the public or discipline regulators.[37] In contrast, Eric Posner and Glen Weyl argue that, if anything, CBA is better suited to financial regulation than to other forms of regulation, because the costs and benefits of financial regulation are “almost all monetary,” and are thus easier to estimate and compare.[38]Research and Cost Benefit Analysis Paper

Determining the right role, if any, for CBA in financial regulation—or any regulatory field—depends on understanding the costs and benefits of CBA in the contexts in which it is practiced. A better understanding of the many facets of CBA involves addressing at least three questions: (1) What is CBA? (2) What are the challenges of quantifying costs and benefits and how can those challenges be addressed? (3) What are the “on-the-ground” regulatory problems that CBA must be able to account for if it is to be an effective regulatory tool in a specific context? The three articles in this issue make important contributions toward addressing these questions.

Amy Sinden’s article highlights the “wide and divergent array of decision-making practices” encompassed by CBA.[39] Through a case study of Entergy v. Riverkeeper, a 2009 U.S. Supreme Court case involving the Environmental Protection Agency’s (EPA) interpretation of Clean Water Act regulations related to power-plant cooling water intakes, Sinden reveals the importance of “distinguishing among different forms of CBA.”[40] In particular, Sinden distinguishes between formal and informal forms of CBA. She cautions against what she calls “false formality,” which occurs when agencies “fail to clearly define where on the formality-informality spectrum a particular CBA falls” and “inappropriately combine[] elements of formal and informal CBA.”[41] False formality leads to irrational outcomes because it results in the misinterpretation of doctrine, muddies debate, and produces intellectual incoherence.[42]

Arden Rowell’s article takes on the task of explaining how CBA can value future costs and benefits. She argues that two aspects of time pose distinct challenges for cost-benefit analysis.[43] First, temporal asymmetry means that time only flows in one direction. This means that “[r]esources, information, harm, and risk can only be presented from the present to the future.”[44] Temporal asymmetry therefore “undermines the possibility of meaningfully reciprocal relationships between the present and the future.”[45] Rowell argues that regulators should respond to this temporal challenge by being especially attentive to the distributional issues related to temporal asymmetry.[46] Second, the “flow” of time creates challenges for managing the “temporal scope” of cost-benefit analyses.[47] For example, what is the proper endpoint when calculating the costs of nuclear waste?[48] To respond to this challenge, Rowell argues that regulators should clearly delineate the temporal scope of their analyses.[49] Rowell also suggests that regulators “consider calculating temporal ‘break-even’ points to identify the time point when the benefits of a rule will have justified the costs.”[50]Research and Cost Benefit Analysis Paper

Finally, Jeff Sovern discusses CBA from the perspective of a leading scholar of consumer law. Sovern notes that while CBA has often troubled consumer advocates, it may help consumers if it is responsive to the challenges regulators face when crafting effective consumer protection regulations.[51] For example, Sovern explains that many consumer protection rules fail because consumers fail to use them.[52] Sovern’s article therefore provides an important insight into the kinds of complex behavioral considerations for which CBA must be able to account. Sovern also notes the difficulty CBA may face when it attempts to measure the costs and benefits of some rules ex ante.[53] He argues that pilot projects and variation in policy across states may be particularly useful for evaluating policies in such cases.[54] Some benefits of consumer protection, such as financial privacy, may also be particularly difficult to quantify.[55] Sovern argues that consumer protection agencies “should attempt to demonstrate that protections will have benefits, but should not necessarily be forced to quantify those benefits, because often the benefits cannot be quantified.”[56]

Given the evolving and potentially expanding role of CBA, scholarship on CBA is more important than ever. As important as CBA is, it also raises issues that go well beyond CBA, including the nature and purpose of regulation, the role of courts in reviewing administrative decisions, and epistemological questions about the limits of quantification. Indeed, rethinking CBA may even provide a key starting point for rethinking regulation more broadly. The articles in this issue make an important contribution to this crucial and undoubtedly ongoing discussion.Research and Cost Benefit Analysis Paper

Simplicity

Cost-benefit analyses are advantageous because they simplify complex business decisions. Different business projects might entail vastly different types of expenses and details at a low level, but a cost-benefit analysis frames all projects in the same simple terms: total benefits, minus total costs, equals net benefit. The simplicity of the cost-benefit analysis lets businesses compare projects of all types no matter how dissimilar they are.

Objectivity

Another benefit of a cost-benefit analysis is that it provides an objective way to compare projects. Business owners who are emotionally attached to or have time invested in certain projects may be predisposed to pursue those projects, even if there are better options available. Comparing projects based on the actual financial costs and benefits eliminates the emotional element and may help business managers overcome biases for the good of the business.

Goal Setting

While a cost-benefit analysis can help a company estimate the net benefit of a project, benefits are typically more difficult to predict than costs. For example, a company might know the exact cost of the materials needed to produce a new product, but it is impossible to know exactly how many units a new product will sell when it goes on the market. Estimating costs and benefits can, however, give a business an idea of the lowest amount of revenue a new project needs to produce to break even and help set revenue goals to make projects profitable.Research and Cost Benefit Analysis Paper

Considerations

A cost-benefit analysis can be a useful tool for decision-making, but the accuracy of a cost-benefit analysis is limited by the thoroughness of recognizing likely costs and benefits. If a business fails to recognize potential costs and benefits, it can cause poor results that lead to sub-optimal decisions. For example, if a factory fails to account for the environmental impact of its operations as a cost, it could lead it toward projects that create more pollution, which might be bad for society and hurt the company's reputation.

Cost benefit analysis is an objective examination of what you spend, relative to what you gain to achieve an outcome. The analysis can be laid out in dollars and cents; or, in terms of investment, in revenue and profit. Alternatively, it can evaluate intangibles such as social advantages and disadvantages. The strengths of a cost benefit analysis approach are closely tied to its weaknesses: it provides clarity, but sometimes does so in situations that aren't as clear cut as they seem.

Advantage: Clarity in Unpredictable Situations

Performing a cost benefit analysis gives you the opportunity to delve into specifics about what you are spending to launch a product or to invest in an advertising campaign. The act of defining and listing these costs is a valuable exercise, forcing you to identify and evaluate each upcoming expenditure. The process can benefit you, even though it's often impossible to fully predict every expense you will incur. Unpredictable situations and expenditures are an inevitable part of every venture, but trying to predict them will help you anticipate some curve balls.Research and Cost Benefit Analysis Paper

Disadvantage: Does Not Account for All Variables

The ostensible clarity provided by a cost benefit analysis can give you the illusion that you have covered your bases, when actually there is so much more to know. Just as you will almost certainly encounter unforeseen costs, you may reap benefits that you did not anticipate or a venture may fail to yield the advantages you anticipated. Performing a cost benefit analysis may lead you to believe that you know what to expect and have made a clear and informed decision, when the actual outcome depends on many variables that will unfold over time.

Advantage: Helps You Make Rational Decisions

A cost benefit analysis is in part a tool geared toward helping you make rational, rather than emotional, decisions. By laying out the costs you will incur, to the best of your knowledge, you circumvent the impulse to launch a venture simply because it appeals to you or because you have an emotional tie to a vendor or to an anticipated outcome. The act of listing and evaluating costs and benefits forces you to look at these variables as objectively as possible.

Disadvantage: Removes Gut Instinct

However, making decisions based on gut instinct isn't necessarily a faulty approach. If you feel strongly that a course of action is the right one for your business, even though your cost benefit analysis shows it may not be worth the expense, proceed with caution. Act with the awareness that you're taking a risk, and then measure and evaluate the results so that you can proactively change course, if the costs really do end up outweighing the benefits.Research and Cost Benefit Analysis Paper

The Disadvantages of a Cost Benefit Analysis

1. Potential Inaccuracies in Identifying and Quantifying Costs and Benefits

A cost benefit analysis requires that all costs and benefits be identified and appropriately quantified. Unfortunately, human error often results in common cost benefit analysis errors such as accidentally omitting certain costs and benefits due to the inability to forecast indirect causal relationships. Additionally, the ambiguity and uncertainty involved in quantifying and assigning a monetary value to intangible items leads to an inaccurate cost benefit analysis. These two tendencies lead to inaccurate analyses, which can lead to increased risk and inefficient decision-making.

2. Increased Subjectivity for Intangible Costs and Benefits

Another disadvantage of the cost benefit analysis is the amount of subjectivity involved when identifying, quantifying, and estimating different costs and benefits. Since some costs and benefits are non-monetary in nature, such as increases in customer and employee satisfaction, they often require one to subjectively assign a monetary value for purposes of weighing the total costs compared to overall financial benefits of a particular endeavor. This estimation and forecasting is often based on past experiences and expectations, which can often be biased. These subjective measures further result in an inaccurate and misleading cost benefit analysis.Research and Cost Benefit Analysis Paper

3. Inaccurate Calculations of Present Value Resulting in Misleading Analyses

Since this evaluation method estimates the costs and benefits for a project over a period of time, it is necessary to calculate the present value. This equalizes all present and future costs and benefits by evaluating all items in terms of present-day values, which eliminates the need to account for inflation or speculative financial gains. Unfortunately, this poses a significant disadvantage because, even if one can accurately calculate the present value, there is no guarantee that the discount rate used in the calculation is realistic. A cost benefit analysis template has been developed to help reduce the likelihood of incorrectly calculating the present value of costs and benefits, and it is available for download in the Project Management Media Gallery.Research and Cost Benefit Analysis Paper

4. A Cost Benefit Analysis Might Turn in to a Project Budget

Another disadvantage seen when utilizing a cost benefit analysis is the possibility that the evaluative mechanism turns in to a proposed budget. When a project manager puts together a cost benefit analysis and presents it to a leadership team, the leadership team might view the expected costs as actual rather than estimation, which may lead to misappropriating costs and setting unrealistic goals when approving and implementing a project budget. This can put a project manager in an unfavorable situation when he or she attempts to control costs in order to maintain the expected profit margin.Research and Cost Benefit Analysis Paper
