Efficient experimental designs offer the potential to reduce confidence intervals for parameters of interest in choice models, or to reduce required sample sizes. C-efficiency recognizes the salience of willingness to pay estimates rather than utility function parameters. This study reports on a...

There is a growing body of evidence in the non-market valuation literature suggesting that responses to a sequence of discrete choice questions tend to violate the assumptions typically made by analysts regarding independence of responses and stability of preferences. Decision processes (or...

This study examined how various components of the Certified South Carolina campaign are valued by participating restaurants. A choice experiment was conducted to estimate the average willingness to pay (WTP) for each campaign component using a mixed logit model. Three existing campaign...

We introduce a fast and inexpensive method to rule out potential barriers to adopting a technology. We use this method to asses the role of exogeneous contract enforcement as a barrier to market for Kenya's French Bean export market. We survey 240 farmers in Kirinyaga County, Kenya who were...

This study aimed at estimating the implicit prices farmers are willing to pay (WTP) for maize traits with deliberate focus on drought tolerance. Using choice experiment, we generated 12600 observations from a random sample of 1400 households in communal areas within 14 districts of Zimbabwe....

Stated preference scenarios often provide information on intermediate biophysical processes but omit information on the resulting final services that provide utility. This may cause respondents to speculate about the effects of intermediate outcomes on their welfare, leading to biased welfare...

Data on individuals’ private shopping choices are often used to draw conclusions about their desires for food policies. The purpose of this paper is to test this often-implicit assumption using data from a nationwide survey about animal cloning. We find that although individuals’...
