Researchers use practice rounds to familiarize participants with experimental auction mechanisms. We find a positive correlation between practice bids and bids submitted in later rounds. We consider three explanations for this correlation: a behavioral anchoring effect, a tendency for some...

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...

We propose a nonparametric estimator of bidders' value function based on a kernel estimator of the density quantile function of bids in first price auctions. This estimator provides certain advantage over the conventional approach that relies on the distribution/density ratio of the bids. We use...
