"Basic economic theory predicts that a consumer's willingness to pay for a good is affected by the availability of complements and substitutes. In an auction setting, this theory implies that the presence of complements would increase bid prices for a good, while the presence of substitutes...

In most experimental auctions, researchers ask participants to bid on the same item in multiple potentially binding rounds, posting the price submitted by the top bidder or bidders after each of those rounds. If bids submitted in later rounds are affiliated with posted prices from earlier...

We report the results of an experiment designed to test whether initial endowments affect value estimates elicited from experimental auctions. Comparing bids for one unit of a good, two units of a good, and a second unit of a good when endowed with the first unit, we find that willingness to pay...

We use two experimental valuation methods to estimate consumer demand for genetically modified golden rice. The first is an open-ended choice experiment (OECE) where participants name the quantities of golden rice and conventional rice demanded at each of several price combinations, one of which...
