Benefit costb analysis

It became popular in the s as a simple way of weighing up project costs and benefits, to determine whether to go ahead with a project. As its name suggests, Cost-Benefit Analysis involves adding up the benefits of a course of action, and then comparing these with the costs associated with it. The results of the analysis are often expressed as a payback period — this is the time it takes for benefits to repay costs.

Evaluation[ edit ] CBA attempts to measure the positive or negative consequences of a project, which may include: Effects on non-users or non-participants.

Option value or other social benefits. A similar breakdown is employed in the environmental analysis of total economic value.

Both costs and benefits can be diverse. Financial costs tend to be most thoroughly represented in cost-benefit analyses due to relatively abundant market Benefit costb analysis. The net benefits of a project may incorporate cost savings or public willingness to pay compensation implying the public has no legal right to the benefits of the policy or willingness to accept compensation implying the public has Benefit costb analysis right to the benefits of the policy for the welfare change resulting from the policy.

The guiding principle of evaluating benefits is to list all categories of parties affected by an intervention and add the positive or negative value, usually monetary, that they ascribe to its effect on their welfare.

The actual compensation an individual would require to have their welfare unchanged by a policy is inexact at best. Surveys stated preference techniques or market behavior revealed preference techniques are often used to estimate the compensation associated with a policy.

Stated preference technique is a direct way of assessing willingness to pay. Because it involves asking people directly to indicate their willingness to pay for some environmental feature, or some outcome that is closely connected to the state of the environment.

Revealed preference technique is an indirect approach to individual willingness to pay. People make market choices among certain items that have different characteristics related to the environment, revealing the value they place on these environmental factors.

However, this can sometimes be avoided by using the related technique of cost-utility analysis, in which benefits are expressed in non-monetary units such as quality-adjusted life years. For example, road safety can be measured in terms of cost per life saved, without formally placing a financial value on the life.

However, such non-monetary metrics have limited usefulness for evaluating policies with substantially different outcomes. Additionally, many other benefits may accrue from the policy, and metrics such as 'cost per life saved' may lead to a substantially different ranking of alternatives than traditional cost—benefit analysis.

BREAKING DOWN 'Cost-Benefit Analysis'

Statistical murder Another controversy is valuing the environment, which in the 21st century is typically assessed by valuing ecosystem services to humans, such as air and water quality and pollution.

Time and discounting[ edit ] CBA generally attempts to put all relevant costs and benefits on a common temporal footing using time value of money calculations. This is often done by converting the future expected streams of costs and benefits into a present value amount using a discount rate. The selection of a discount rate for this calculation is subjective.

A smaller rate values future generations equally with the current generation. Empirical studies suggest that people discount future benefits in a way similar to that described in these calculations.

One example of this issue is the equity premium puzzlewhich suggests that long-term returns on equities may be higher than they should be, after controlling for risk and uncertainty. If so, market rates of return should not be used to determine the discount rate, as this would have the effect of undervaluing the distant future e.

This can be factored into the discount rate to have uncertainty increasing over timebut is usually considered separately. Particular consideration is often given to agents' risk aversion — preferring a situation with less uncertainty to one with higher uncertainty, even if the latter has a higher expected return.

In such a context, expected return calculations provide biased estimates of cost-benefits for a project, as they fail to account for differences in the degree of uncertainty.

Alternatively a more formal risk analysis can be undertaken using Monte Carlo simulations. History[ edit ] The French engineer and economist Jules Dupuitcredited with the creation of cost—benefit analysis.

Over the s, CBA was applied in the US for water quality, [17] recreation travel, [18] and land conservation. Government guidebooks for the application of CBA to public policies include the Canadian guide for regulatory analysis, [25] Australian guide for regulation and finance, [26] US guide for health care programs, [27] and US guide for emergency management programs.

This presented cost—benefit results and detailed environmental impact assessments in a balanced way.

Cost–benefit analysis (CBA), sometimes called benefit costs analysis (BCA), is a systematic approach to estimate the strengths and weaknesses of alternatives (for example in transactions, activities, functional business requirements or projects investments); it is used to determine options that provide the best approach to achieve benefits while preserving savings.

It is a top journal. It is generally assumed that cost estimation involves a mere toting up of the expenditures that affected parties must make, as in our example of the firm controlling air pollution. As suggested above, however, matters are more complicated than this. "Benefit-cost analysis is crucially important in determining the contribution of economics to policy decisions.

The Journal of Benefit-Cost Analysis, as the outstanding forum for refinement of benefit-cost analysis, is key in promoting its further development.

It is a top journal. A cost-benefit analysis finds, quantifies, and adds all the positive factors involved in a proposed course of action. These are the benefits. Then all the negatives, or costs, are identified, quantified, and subtracted.
