Using a choice experiment survey, the marginal willingness to pay (WTP) among Swedish households for reductions in power outages is estimated.

We investigate the importance of the social context for people’s voluntary contributions to a national park in Costa Rica, using a natural field experiment.

Although conventional economic theory proposes that only the absolute levels of income and consumption matter for people’s utility, there is much evidence that relative concerns are often important.

This study employed a choice experiment (CE) to ascertain consumer preferences and willingness to pay (WTP) for non-market food product quality attributes. Data were obtained from a large mail survey and estimated with a random parameter logit model.

The European Union has been relatively cautious about using biotechnology in food production. A label regime combined with the right of individual member states to ban introduction of new genetically modified (GM) strains means thatGMfood products in effect are banned in many countries.

We show how it is possible to empirically test whether a ban can be motivated by reference to potential negative externalities. This is followed up by results from a choice experiment.We cannot reject the hypothesis of equal WTP for a ban and a labeling scheme.

Using an experimental approach, we investigate the risk preferences of artisanal fishermen in Tanzania waters of Lake Victoria. The experiment concerns pairwise comparisons of hypothetical fishing trips that vary in expected mean and spread of the net revenue.

This paper compares consumer preferences for immunocastration versus surgical castration and no castration using willingness- to-pay estimates from a choice experiment.

Results suggest that consumers place a higher value on pork from immunocastrated pigs than pork from surgically castrated pigs. In contrast, consumers reveal negative valuations of pork from intact boars as compared to pork from surgical castrates. We also show how a binary heteroskedastic logit model can be used to accommodate a larger variance for later choice sets within a choice experiment.

The proportion of money sent, which is typically assumed to reflect trust, decreased significantly as the stake
size was increased in a trust game conducted in rural Bangladesh.

Nevertheless, even with very large stakes, most senders and receivers sent substantial fractions.

This paper reports the results of a stated preference survey in the highlands of Ethiopia where the farmers are given a choice between an agricultural extension package and a local public - representing two major developing strategies. The study finds that a majority of people prefers the public good.

Individuals’ preferences for risk and inequality are measured through choices between imagined societies and lotteries.
