The five dimensions cannot be developed or viewed in isolation, they must be developed together in an iterative process because they are intimately interconnected. Proposals with long term costs and benefits must consider whether longer term structural changes may occur in the economy or society. Such external structural shifts may arise from demographic, technological, environmental, cultural, or other similar external changes.
This requirement for consideration also extends to long-list stage and throughout the appraisal process. National policy objectives that may have significant favourable or adverse effects on parts of the UK, should also be appraised from the relevant place based perspective, as well as from that of the UK as a whole. This consideration supports advice to decision makers based on a wider view of the effects of alternative options than just reporting on a nationwide bottom line. The results of this appraisal must be made visible to decision makers – see Chapter 7. Longlist appraisal and selection of the shortlist is a crucial function of the economic dimension explained more fully in Chapter 4, and in the family of Business Case Guidance documents available from the Green Book web pages. The selection of a preferred option from the shortlist requires interaction between the strategic and economic dimension and the commercial, financial and management dimensions of the case.

Despite the fair value requirement for all equity investments, IFRS 9 contains guidance on when cost may be the best estimate of fair value and also when it might not be representative of fair value. The big peak which is visible in the last quarter of 2008 was caused by the credit crisis (the default of Lehman Brothers and Bear Stearns, and the sale of Merrill Lynch, etc). Due to the lack of liquidity in the market during the crisis, the (liquidity) spreads in the US became a lot higher than those in Europe. To make up for this window of arbitrage, the basis spread decreased at a similar pace.
- For example if Projects A and B have identical costs and benefits but Project B delivers a year earlier, time preference gives Project B, a higher present value because it is discounted by a year less than project A.
- The risk a change in law or regulations will affect the costs or benefits of a project.
- The value of a SLY is derived from the social value of a small change in the probability (the risk) of losing or gaining a year of life expectancy.
- Building taxation into a discounted cash flow answer involves dealing with ‘the good the bad and the ugly’!
Flooding and coastal erosion can lead to social costs (e.g. harm to people and damage to property, infrastructure and the environment). Typical damage per property, per flood event varies from around £8,000 to £11,000 for a flood of less than 0.1 metres in depth, to between £40,000 and £45,000 for a flood in excess of 1.2 metres in depth (20/21 prices). Monitoring and evaluation should be part of the development and planning of an intervention from the start. They are important to ensure successful implementation and the responsible, transparent management of public resources.

Expected values result from multiplying the expected cost if it occurs by the expected likelihood of it materialising. This requires objectively based estimates of the percentage likelihood of a risk occurring. Low probability high impact risks should be noted in the risk register to make the decision maker aware. Effective risk costing will be supported if organisations put in place well designed risk assessment processes supported by effective routine data recording. A longer appraisal period may be suitable where intervention is likely to have significant social costs or benefits beyond 60 years. Possible examples include immunisation programmes, the safe treatment and storage of nuclear waste or interventions that reduce climate change risks.
The do minimum does not take advantage of any opportunities for additional changes that may occur. It may or may not, be the option eventually chosen, but it is essential because it provides a second important benchmark that can reveal the real value of additional changes. Comparison with the “Do Minimum” option reveals whether options that take advantage of additional opportunities to make changes are worthwhile or not. If comparison with the “Do Minimum” reveals that they add more cost and risk than they add value, they are regarded as likely to be pointless “gold plating”. However, this may not be the case where there is a widely recognised benefit that is not readily or credibly quantifiable or monetisable.

Discounting in appraisal of social value is based on the concept of time preference – that generally people prefer to receive goods and services now rather than later. Social CBA and Social CEA techniques are “marginal analysis” principally employed to consider changes between alternative options, https://grindsuccess.com/bookkeeping-for-startups/ and compare alternative options based on a static model of the world. Significant non-marginal issues involving fundamental changes in the relationships on which models, estimates, and forecasts are based must be analysed during the research phase in advance of the longlist stage.
It may be unrealistic to produce a single number
that adequately captures the full impact of an option. Public sector financial costs should be calculated using the international National Accounts statistical framework produced for the UK by the Office of National Statistics. Public sector financial costs are recorded on an accruals basis consistent with departmental budgets, as per the Consolidated Budgeting Guidance. These distinctions apply to any intervention with financial impacts on the public sector. The initial pass through the options framework rejects option choices that do not meet the SMART objectives, or which are judged unacceptable by a failure to satisfy the CSFs to a satisfactory degree.

Understanding natural capital provides a framework for improved appraisal of a range of environmental effects alongside potentially harmful externalities such as air pollution, noise, waste and GHGs. In cases where alternative levels of fatality risk are involved in option design, VPF allows this to be taken into account. The value concerned is known as the value of the risk of “a statistically prevented fatality.” It has been widely used for many years, particularly in transport.
Higher estimates of the marginal utility of income will mean the value of an additional pound declines more quickly relative to increases in income. Carbon value assumptions for the traded and non-traded sectors are available for 3 different scenarios (low, central, and high) to enable sensitivity analysis. They are also provided in the table below (£241 per tonne of CO2 in 20/21 prices). Biodiversity can be thought of as a core component of natural capital that supports the provision of environmental goods and services to people.
