An ever increasing number of experiments attempts to elicit risk preferences of a population of interest with the aim of calibrating parameters used in economic models. We are concerned with two types of selection effects, which may affect the external validity of standard experiments: Sampling...

We combine data from a risk preference elicitation experiment conducted on a representative sample via the Internet with laboratory data on student subjects for the same experiment in order to investigate effects of implementation mode and of subject pool selection. We find that the frequency of...
