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....

A recent study published by Murphy et al. (2005) reported results of a meta-analysis of hypothetical bias using 28 valuation studies. The authors found a median ratio of hypothetical to actual values of 1.35 but they did not investigate the ratio of scales of the hypothetical and actual value...

Researchers are seeking effective, low cost means of gathering high quality data. Technological advancements offer new avenues for achieving this objective. Web based surveys are relatively common outside the economics discipline however applied non-market valuation practitioners have been slow...

Benefit transfer entails using estimates of non-market values derived at one site as approximations to benefits at other sites. The method finds favour because it can be applied quickly and cheaply, however the validity of benefit transfer is frequently questioned. Published studies generally...

Stated preference approaches are widely used in non-market valuation. However, their potential uses extend far beyond valuation. In particular they can be used to assess efficiency of resource allocations and to design optimal resource allocations. Changes to the government budget were evaluated...

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

Nanotechnology has tremendous potential in food and agriculture. Few economic studies focused on specific products made using nanotechnology, let alone food or food related products. Using a national choice experiment survey, this analysis examines consumers’ valuations for nano-attributes. As...

This study employs a choice experiment approach to investigate consumers’ preferences and willingness-to-pay (WTP) for organic food products. We use mixed logit and latent class models to examine preference heterogeneity. The results revealed significant heterogeneity in preferences for...

Efficient experimental designs offer the potential to reduce required sample sizes, or to reduce confidence intervals for parameters of interest, in choice experiments. Choice experiment designs have typically addressed efficiency of utility function parameter estimates. The recently developed...
