Contingent valuation surveys were first proposed in theory by S.V. Ciriacy-Wantrup (1947) as a method for eliciting market valuation of a non-market good.The first practical application of the technique was in 1963 when Robert K. Davis used surveys to estimate the value hunters and tourists placed on a particular wilderness area.
According to the constructed preference view, consumer willingness to pay is a context-sensitive construct; that is, a consumer's WTP for a product depends on the concrete decision context. For example, consumers tend to be willing to pay more for a soft drink in a luxury hotel resort in comparison to a beach bar or a local retail store.
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.
Contingent valuation is a common method in identifying how consumers value various things like healthcare, safety and the environment. The WTA and WTP are very common methods for contingent valuation, where subjects are asked exactly how much money they would be willing to accept in order to receive one less unit of the goods or conversely how ...
Contingent valuation is a stated preferences technique. [13] Contingent valuation estimates the value a person places on a good by asking him or her directly. [14] It is essentially surveys for individuals on how much they would be willing to pay for some intangible benefits or to avoid some intangible harms.
The Becker–DeGroot–Marschak method (BDM), named after Gordon M. Becker, Morris H. DeGroot and Jacob Marschak for the 1964 Behavioral Science paper, "Measuring Utility by a Single-Response Sequential Method" is an incentive-compatible procedure used in experimental economics to measure willingness to pay (WTP).
Non-use value is the value that people assign to economic goods (including public 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. Non-use value as a category may include:
The value of statistical life (VSL) in Singapore was estimated in 2007 via a contingent valuation survey that elicits willingness-to-pay (WTP) for mortality risk reductions, which interviewed 801 Singaporeans and Singapore Permanent Residents aged 40 and above, entailing a value of statistical life of approximately S$850,000 to S$2.05 million ...
