The embedding effect is an issue in environmental economics and other branches of economics where researchers wish to identify the value of a specific public good using a contingent valuation or willingness-to-pay (WTP) approach. The problem arises because public goods belong to society as a whole, and are generally not traded in the market. Because market prices cannot be used to value them, researchers ask a sample of people how much they are willing to pay for the public good, wildlife preservation for example. The results can be misleading because of the difficulty, for individual society members, of identifying the particular value that they attach to one particular thing which is embedded in a collection of similar things (e.g. The Tower of London within the set of all globally important historic monuments or Caernarvon Castle within the set of all Welsh Scheduled Monuments). A similar problem occurs with a wider selection of public goods (for example whether spending on preserving a specific wetland is more important than preserving a specific persons life for the next two years using taxpayers' money). The embedding effect suggests the contingent valuation method is not an unbiased approach to measuring policy impacts for cost-benefit analysis of environmental, and other government policies.
Few government policies are independent of any other governmental policy. Most policies involve either substitute or complementary relationships with others at either the same or different intergovernmental level. For example, in the USA, the protection of coastal water quality is a goal of both state and multiple federal agencies. The Clean Water Act, wetlands protection programs, and fisheries management plans all address coastal water quality. These policies may be substitutes or complements for each other. These relationships complicate the application of the contingent valuation method. The resulting problems that may be encountered have been called the part-whole bias and sequencing and nesting (see below).
One method of overcoming some aspects of this problem is to ask two questions (1) How much would you be willing to contribute to a specific tax fund for the whole set of items to be preserved? (e.g. all Coral Sea areas west of Australia) followed by (2) How much of this would you like to give to the preservation of the specific named item? (e.g. the Great Barrier Reef). These questions may also be supplemented by questions which ask about the respective importance of alternatives e.g. whether the preservation of the Great Barrier Reef is more/the same/less important than other public goods such as poor relief, health care, education etc.
If the contingent valuation method is used to elicit willingness to pay for two government policies independently (the parts) the sum of the independently estimated willingness to pay amounts may be different from the willingness to pay elicited for both projects (the whole). This result is troubling if the projects are geographically related, for example, different wilderness areas (McFadden, 1994). This result does not violate the nonsatiation axiom of consumer theory if projects are perfect substitutes (Carson and Mitchell, 1995). Several applications of the contingent valuation method have found an absence of part-whole bias (e.g., Whitehead, Haab, and Huang, 1998).
A related issue occurs with the sequential valuation of projects. Consider a two-part policy valued in two different sequences. The willingness to pay for a project when valued first will be larger than when the question is placed second. Independent valuation, in effect valuing each project at the beginning of a sequence, will always lead to the largest of the possible willingness to pay estimates. This result is expected for the value of public goods estimated with the contingent valuation method due to substitution and income effects (Hoehn and Randall, 1989; Carson, Flores, and Hanemann, 1998).
Environmental economics is a sub-field of economics concerned with environmental issues. It has become a widely studied subject due to growing environmental concerns in the twenty-first century. Environmental economics "undertakes theoretical or empirical studies of the economic effects of national or local environmental policies around the world. ... Particular issues include the costs and benefits of alternative environmental policies to deal with air pollution, water quality, toxic substances, solid waste, and global warming."
Transport economics is a branch of economics founded in 1959 by American economist John R. Meyer that deals with the allocation of resources within the transport sector. It has strong links to civil engineering. Transport economics differs from some other branches of economics in that the assumption of a spaceless, instantaneous economy does not hold. People and goods flow over networks at certain speeds. Demands peak. Advance ticket purchase is often induced by lower fares. The networks themselves may or may not be competitive. A single trip may require the bundling of services provided by several firms, agencies and modes.
The value of life is an economic value used to quantify the benefit of avoiding a fatality. It is also referred to as the cost of life, value of preventing a fatality (VPF), implied cost of averting a fatality (ICAF), and value of a statistical life (VSL). In social and political sciences, it is the marginal cost of death prevention in a certain class of circumstances. In many studies the value also includes the quality of life, the expected life time remaining, as well as the earning potential of a given person especially for an after-the-fact payment in a wrongful death claim lawsuit.
Real options valuation, also often termed real options analysis, applies option valuation techniques to capital budgeting decisions. A real option itself, is the right—but not the obligation—to undertake certain business initiatives, such as deferring, abandoning, expanding, staging, or contracting a capital investment project. For example, real options valuation could examine the opportunity to invest in the expansion of a firm's factory and the alternative option to sell the factory.
In finance, valuation is the process of determining the value of a (potential) investment, asset, or security. Generally, there are three approaches taken, namely discounted cashflow valuation, relative valuation, and contingent claim valuation.
Cost–benefit analysis (CBA), sometimes also called benefit–cost analysis, is a systematic approach to estimating the strengths and weaknesses of alternatives. It is used to determine options which provide the best approach to achieving benefits while preserving savings in, for example, transactions, activities, and functional business requirements. A CBA may be used to compare completed or potential courses of action, and to estimate or evaluate the value against the cost of a decision, project, or policy. It is commonly used to evaluate business or policy decisions, commercial transactions, and project investments. For example, the U.S. Securities and Exchange Commission must conduct cost-benefit analyses before instituting regulations or deregulations.
In psychology and behavioral economics, the endowment effect, also known as divestiture aversion, is the finding that people are more likely to retain an object they own than acquire that same object when they do not own it. The endowment theory can be defined as "an application of prospect theory positing that loss aversion associated with ownership explains observed exchange asymmetries."
Contingent valuation is a survey-based economic technique for the valuation of non-market resources, such as environmental preservation or the impact of externalities like pollution. While these resources do give people utility, certain aspects of them do not have a market price as they are not directly sold – for example, people receive benefit from a beautiful view of a mountain, but it would be tough to value using price-based models. Contingent valuation surveys are one technique which is used to measure these aspects. Contingent valuation is often referred to as a stated preference model, in contrast to a price-based revealed preference model. Both models are utility-based. Typically the survey asks how much money people would be willing to pay to maintain the existence of an environmental feature, such as biodiversity.
Ecosystem valuation is an economic process which assigns a value to an ecosystem and/or its ecosystem services. By quantifying, for example, the human welfare benefits of a forest to reduce flooding and erosion while sequestering carbon, providing habitat for endangered species, and absorbing harmful chemicals, such monetization ideally provides a tool for policy-makers and conservationists to evaluate management impacts and compare a cost-benefit analysis of potential policies. However, such valuations are estimates, and involve the inherent quantitative uncertainty and philosophical debate of evaluating a range non-market costs and benefits.
A shadow price is the monetary value assigned to an abstract or intangible commodity which is not traded in the marketplace. This often takes the form of an externality. Shadow prices are also known as the recalculation of known market prices in order to account for the presence of distortionary market instruments. Shadow prices are the real economic prices given to goods and services after they have been appropriately adjusted by removing distortionary market instruments and incorporating the societal impact of the respective good or service. A shadow price is often calculated based on a group of assumptions and estimates because it lacks reliable data, so it is subjective and somewhat inaccurate.
Environmental goods are typically non-market goods, including clean air, clean water, landscape, green transport infrastructure, public parks, urban parks, rivers, mountains, forests, and beaches. Environmental goods are a sub-category of public goods. Concerns with environmental goods focus on the effects that the exploitation of ecological systems have on the economy, the well-being of humans and other species, and on the environment. Users not having to pay an upfront cost and external factors like pollution that can damage environmental goods indefinitely are some of the challenges in protecting environmental goods.
The following outline is provided as an overview of and topical guide to finance:
Non-use value is the value that people assign to economic goods even if they never have and never will use it. It is distinguished from use value, which people derive from direct use of the good. The concept is most commonly applied to the value of natural and built resources.
In economics, willingness to accept (WTA) is the minimum monetary amount that а person is willing to accept to sell a good or service, or to bear a negative externality, such as pollution. This is in contrast to willingness to pay (WTP), which is the maximum amount of money a consumer is willing to sacrifice to purchase a good/service or avoid something undesirable. The price of any transaction will thus be any point between a buyer's willingness to pay and a seller's willingness to accept; the net difference is the economic surplus.
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.
