Experimental Auction Methods in Consumer Valuation Studies

Experimental auction methods have emerged as a rigorous means to elicit consumers’ willingness to pay (WTP) for goods and product attributes under controlled, incentive-compatible conditions. Core designs include the Vickrey second-price auction, where the highest bidder wins but pays the second-highest bid; the Becker–DeGroot–Marschak (BDM) mechanism, which compares a participant’s bid to a randomly drawn price; and multiple price list formats, in which respondents choose between a series of price-quantity options. These mechanisms are valued for minimising strategic misrepresentation and hypothetical bias, thereby producing more accurate estimates of actual market behaviour. Applications span food quality, environmental attributes, agricultural inputs and cultural products, often in diverse settings from developed economies to low-income countries. Key challenges include learning effects over repeated rounds, state-dependent biases such as projection bias, liquidity constraints that alter bidding behaviour, and the cognitive complexity experienced by participants. By integrating real monetary stakes, these methods have informed policy design in areas as varied as seed quality interventions, sustainable labelling schemes and energy efficiency programmes. Cross-method comparisons have illuminated trade-offs between ease of implementation and measurement precision, guiding researchers towards mechanisms that balance respondent comprehension with robust WTP estimation. The collective evidence underscores the global significance of experimental auctions as both a theoretical tool for understanding consumer choice under uncertainty and a practical instrument for market and policy assessment.

The graph below shows the total number of articles in experimental auction methods in consumer valuation studies across all publications each year (not limited to Nature Index journals).

Technical terms

Vickrey second-price auction: An auction in which the highest bidder wins but pays the second-highest bid, ensuring truthful bidding.

Becker–DeGroot–Marschak mechanism (BDM): A valuation method where a participant’s bid is compared to a randomly drawn price, and if the bid exceeds that price they purchase at the random price.

Multiple price list (MPL): A format presenting respondents with a sequence of binary choices between different prices and quantities to reveal WTP.

Willingness to pay (WTP): The maximum amount an individual is prepared to spend for a good or attribute under incentive-compatible conditions.

Incentive compatibility: A property of a mechanism that aligns truthful reporting with the participant’s best interest.

Hypothetical bias: The tendency for stated WTP in hypothetical scenarios to exceed actual payment behaviour.

Projection bias: A cognitive error where individuals overestimate future preferences based on their current state.
