Net social benefit

Proponents of the laboratories counter that, despite these shortcomings, the laboratories seiwe a vital mission of undertaking the high risk and expensive investments that the private sector would never agree to invest in. Although natural gas research and development was minimal, DOE support accelerated technological advances on natural gas-fired turbines. Much of the research and development at the laboratories has provided a net social benefit to the nation and economy, work such as safe nuclear reactors and the development of sophisticated defense weapons. 

Cost-benefit analysis uses monetary valuations of the morbidity and mortality consequences of diseases or interventions. This allows estimation of the absolute and relative net social benefit of intervention, calculated as the monetary value of the consequences of an intervention minus the direct costs. Any health or social care intervention with a net social benefit greater than zero (i.e. the benefits are greater than the costs) is worth undertaking. Two approaches have typically been used to value outcomes in monetary values. The first is the human capital approach, where the monetary value of benefit represents the value of changes in the amount or type of work done or use of leisure time as...

On conceptual grounds, then, government involvement in support of innovation is most appropriate when the outcomes of R D are uncertain in technical or market terms, appropriability problems are substantial, but priori large net social benefits might be expected to emerge. While precise measures have not been developed for these concepts beyond a few special bases, there is some research support for their validity. As noted above, studies sponsored by the National Science Foundation tend to confirm the... 

Prospective assessments that use success measures such as extent of diffusion or commercialization avoid the problem of determining net social benefits for alternative courses of action, but this, of course, omits the explicit valuation of the outcomes of those alternatives. Such studies are much less useful as policy assessments because they do not present findings that enable one to determine whether the government is justified (from a full social benefits perspective) in undertaking a particular action. Further, they are more difficult to replicate and, therefore, may be less credible to some audiences. For other audiences, this may be an asset the use of historical data and analysis by analogy can lend credence because of the close tie to actual experience. 

Alternatively one may also use a cost-benefit ratio formula. In this case a quotient of the net present benefits and the net present costs is calculated. If the ratio is >1 the social benefits outweigh the cost. The bigger the ratio, the better the project. 

McGuire (2003) showed that setting the vaccine price equal to mean benefit will elicit the socially efficient level of R D on vaccines. Although this is an efficient solution, it may be subject to criticism on equity grounds. The entire net benefit accrues to manufacturers as profit, and no consumer surplus accrues to the public. McGuire assumed a fully effective vaccine. Benefit should be scaled to reflect the extent to which a vaccine is partially effective. 

No matter what industry in which you are employed, it s possible to pinpoint average salaries paid by employers for specific jobs. One of the best resources for gathering current and accurate salary information (available online or in printed form) is the Salary Wizard from www.Salary.com, which allows you to search—free—average salary informahon by job title (and level), either by national average or specific to a parhcular U.S. city. The site provides a salary range (for base pay), the median salary, and additional information on a total compensahon package (which would include the dollar value of possible bonuses, benefits—including Social Security, 401 (k)/403(b), disability, healthcare, pension, and time off—and the net paycheck eshmate), as well as other useful information. 

If you plan to earn income after retiring, you need to look carefully at the net effect of your earnings on your overall tax bill and plan your income to minimize any adverse effect. In addition to the graduated schedule of federal and state income taxes, consider the effect of earnings on Social Security benefits and the cost of self-employment tax. 

In the valuation of effects (Fig.. 2, bottom box), an assessment is made of the relative importance of the various effects arising from each control option. The aim is to arrive at some sort of overall measure of the value of the option considered. This value is then compared to the costs of the action to obtain a net benefit. The valuation of effects (cf. Section 2) will depend on the social values and attitudes of individuals or groups in the society. It is therefore an entirely subjective activity. 

Analysis on a national level and per social group Another and more precise approximation to the net aggregate consumption benefits of the project takes into account the adjustments necessary when the social value of funds devoted to investments exceed the social value of the same funds devoted to consumption. This is the case when the government has not been in a position to raise savings - and investment - to the point where the marginal rate of return on investment, q, is equal to the social rate of discount, i. If 100 units consumed now is considered equivalent to 110 units consumed the next year, the social rate of discount i is 10%. A unit of money withdrawn from consumption to an investment now should have a rate of return of at least i in order to increase the consumption in future years to the desired level. 

The fourth stage of the methodology compares the expected present value of the total social cost savings to the present value of the R D expenditures required to realize the innovation. Ratios, such as the net benefit to government R D cost ratio, can be used to compare the worth of various alternative projects.

Individuals who lose financial support through their unemployment insurance, activity benefit support etc. are always eligible to apply for social assistance as the last safety-net. 

In principle, BCA is simplicity itself add up the benefits of a project, add up its costs, and make approval dependent on whether the difference, total net benefits, is written in black ink or red. Of course, close up this simplicity disappears there are great technical hurdles to be overcome in such areas as valuing intangible or difficult-to-measure costs and benefits, deciding on the rate of discoimt to apply to outcomes that will occur in the future, and, if the analyst is conscientious, adjusting for the effect that income inequality has on the dollar value of outcomes to different social classes. This keeps economists busy. Despite these complications, however, they can appeal to the overall common sense of the benefit-cost framework to gain support in the political process. In the early applications to water policy the technical problems were not important -the most wasteful projects were easily identified - but as the use of BCA widened the problems increased, and different studies of the same proposal worild often come up with wildly divergent numbers. 

What rarely seems to enter into assessments by engineers (and other professionals) about such undertakings is whether any considerations apply in a particular situation that should trump calculations that yield positive net benefit. For example, suppose one social group is likely to bear a disproportionate share of the harm, the risk of harm, or, more generally, the costs and risks of the action, practice, or project. If so, perhaps that fact should trump a benefit-harm-risk analysis that finds positive net benefit for the action under consideration and block the use of Rl to justify proceeding with that action.
