Stated preference valuation is a term for survey-based methods which are often applied to estimate the willingness to pay (WTP) for non-market goods (e.g., environmental public goods) or policies that deliver them. In contrast to revealed preferences methods (using observations on actual behaviour), they are based on hypothetical choices made in carefully designed situations (e.g., votes).

The most popular stated preference valuation methods are the contingent valuation (in which usually a single WTP-question is asked) and discrete choice experiments (DCE) (in which respondents are asked to repeatedly choose the most preferred alternatives that are described using selected attributes and attribute levels).
