| Shrnutí≠ | The contingent valuation method (CVM) is a survey-based stated-preference technique for estimating the economic value people place on goods that are not traded in markets — clean air, an endangered species, a wilderness area, the existence of a natural resource. Respondents are presented with a carefully constructed hypothetical scenario and asked how much they would be willing to pay for a described change in provision; their answers are used to estimate mean or median willingness to pay, including non-use (existence) values that no market reveals. | A choice experiment (discrete choice experiment, DCE) is an attribute-based stated-preference method that values non-market goods by describing them as bundles of characteristics and asking respondents to choose repeatedly among competing alternatives — one of which always carries a cost. Grounded in random utility theory, the choices are modeled with a discrete-choice model whose coefficients reveal the relative value of each attribute, and dividing any attribute's coefficient by the cost coefficient yields its marginal willingness to pay. |
