A choice experiment eliciting environmental values with both real and hypothetical trade-offs is set up in order to test for hypothetical bias. A larger hypothetical bias was found in a between-subject than in a within-subject design, using otherwise identical scenarios, which can explain...

Using a random sample of individuals in rural Bangladesh, this paper investigates people’s preferences regarding relative values of lives when it comes to different ages of the individuals being saved. By assuming that an individual has preferences concerning different states of the world, and...

Hypothetical bias in stated-preference methods appears sometimes to be very large, and other times non-existent. This is here largely explained by a model where people derive utility from a positive self-image associated with morally commendable behavior. The results of a choice experiment are...

This paper proposes that people derive utility from a positive self-image, influenced by ethical views, internal honesty, and consistency between sequential choices. A model is tested by conducting the same choice-experiment for two WWF-campaigns in three different contexts. It predicts that...

A choice experiment eliciting environmental values is set up in order to test for hypothetical bias based on both within and between sample designs. A larger hypothetical bias was found in the latter case, which explains parts of the previous diverging results in the literature. People seem to...

Although in-situ conservation is increasingly considered an efficient way of conserving plant genetic resources, little is known about the incentives and constraints that govern conservation decisions among small farm holders in developing countries. Using a choice experiment approach, we...

This paper reports the results of a choice experiment designed to estimate the private welfare costs of stay-at-home policies during the COVID-19 pandemic. The study is conducted on a large and representative sample of the Swedish population. The results suggest that the welfare cost of a...

In a split sample design, we examine how the number of choice sets, design of the first choice set (starting point), and the choice of attribute levels in the cost attribute affect the precision in the elicited preferences in otherwise completely identical choice experiment surveys. These issues...

From 1997 to 2005, an astonishing 5,200 million USD was invested to reduce cocaine production in Colombia, the world's main cocaine producer. However, little is known about the effectiveness of policies targeting coca cultivation. This paper uses a surveybased experiment to evaluate the effects...
