Option value (cost–benefit analysis)

Option value (cost–benefit analysis) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Option value (cost–benefit analysis) rather than just read about it. In short: In cost–benefit analysis and social welfare economics, the term option value refers to the value that is placed on private willingness to pay for maintaining or preserving a public asset or service even if there is little or no likelihood of the individual actually ever using it.

Reference excerpt

In cost–benefit analysis and social welfare economics, the term option value refers to the value that is placed on private willingness to pay for maintaining or preserving a public asset or service even if there is little or no likelihood of the individual actually ever using it. The concept is most commonly used in public policy assessment to justify continuing investment in parks, wildlife refuges and land conservation, as well as rail transportation facilities and services. It is also recognized as an element of the total economic value of environmental resources. This concept of "option value" in cost–benefit analysis is different from the concept used in finance, where the term refers to the valuation of a financial instrument that provides for a future purchase of an asset. (See Option time value.) However, the two can be related insofar as both can be interpreted as a valuation of risk factors.

Application In the environmental research literature, option value is commonly interpreted as the value of preserving threatened natural resources so that they might be available for use in the future. It has been applied for establishing the value of preserving wildlife habitats, wilderness areas, and water recreation resources. In the transportation research literature, option value is most commonly interpreted as estimated the value that non-users are willing to pay to ensure continued availability of a rail transport facility and its service (as an option that will be available in the future). It is recognized as a type of benefit to be considered in cost benefit evaluation of transportation investment alternatives by the UK Department for Transport and the Scottish Government, and has also been used for assessment of regional rail projects in the Netherlands. In the US, option value is recognized in several transportation benefit-cost analysis guides, including those of the Transportation Research Board's Committee on Transportation Economics, the Transit Cooperative Research Program, and the Victoria Transport Policy Institute.

Evolution The term "option value" and its theoretical underpinnings as a non-user benefit were initially developed in 1964 by Burton Weisbrod. It was posited as an element of benefit distinct from the traditional concept of consumer surplus, and it depended on three factors: (1) uncertainty about future need for the asset, (2) irreversibility or high cost of replacement if the asset is lost, and (3) non-storability of the asset. That was followed by an active academic debate about the concept, and refinement of its measurement. Some economists further developed its distinction from consumer surplus and role as an uncertainty risk aversion premium, leading to the suggestion that a concept of "option price" may be more appropriate. Others stressed the irreversibility aspect of the resource and further specified the framework for valuing avoidance of that risk, with suggestions to adopt a concept of "quasi option value" or "irreversibility effect." All of these terms and concepts appear in academic literature. However, the original term "option value" is still commonly used in applied studies (as apparent in works cited in the preceding application section; see also).

Worked examples

Example 1 — a first encounter with Option value (cost–benefit analysis)

Start with the simplest possible case. Write down what Option value (cost–benefit analysis) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Option value (cost–benefit analysis) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Option value (cost–benefit analysis) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Option value (cost–benefit analysis)

In research: Option value (cost–benefit analysis) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Option value (cost–benefit analysis) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Option value (cost–benefit analysis) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Welfare economics, so understanding it makes those chapters shorter.
In everyday life: Look for Option value (cost–benefit analysis) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
