Recent evidence suggests that participants' misunderstanding of experimental auction mechanism can systematically bias auction results. We present a simple technique for testing whether field auction mechanism and, by extension, whether auction bids provide an unbiased estimate of participants'...

In a static setting, willingness to pay for an environmental improvement is equal to compensating variation. However, in a dynamic setting characterized by uncertainty, irreversibility, and the potential for learning, willingness to pay may also contain an option value. In this paper, we...

I propose an alternative approach to auction valuation in which participants indicate the quantity they wish to buy at a series of prices, with the understanding that one will be randomly chosen as the binding price. This technique allows researchers to estimate entire demand curves as well as...

Consumers' willingness to pay for food products decreases when the food label indicates that a food product is produced with the aid of modern biotechnology. This bulletin presents empirical evidence on consumers' willingness to pay for biotech foods based on the presence or absence of labels...

Information about cigarettes can help smokers come to an informed decision about what cigarettes to purchase. Countermarketing information can help smokers make informed decisions, but little is known about the value of this information to smokers. In this article, we use data from experimental...
