We administer the Allais paradox questions to both a representative sample of the Dutch population and to student subjects. Three treatments are implemented: one with the original high hypothetical payoffs, one with low hypothetical payoffs and a third with low real payoffs. Our key findings are: (i) violations in the non-lab sample are systematic and a large bulk of violations is likely to stem from non-familiarity with large payoffs, (ii) we can identify groups of the general population that have much higher than average violation rates; this concerns mainly the lowly educated and unemployed, and (iii) the relative treatment differences in the population at large are accurately predicted by the lab sample, but violation rates in all lab treatments are about 15 percentage points lower than in the corresponding non-lab treatments.

We find that consistency increases with task familiarity and is linked to several personal characteristics such as education, income and asset holdings. Moreover, we investigate the external validity of a laboratory experiment with a student population that implemented the same choice problems as our household panel study. We find that, in line with studies on other biases, deviations from rationality observed in the lab provide a lower bound for deviations in the population at large.Recently, several studies have made significant progress in understanding risk preferences in populations, making use of innovative survey methods and field experiments (Harrison and List 2004) including game shows with large stakes (Post et al. 2008;Andersen et al. 2008). From the perspective of these studies, the present paper takes one step back by focussing on consistency of risk preferences with expected utility theory in a representative subject poolwell over 1,400 members of the CentER Panel, a representative sample of the Dutch population. We do this by falling back on the oldest consistency test of all-the Allais paradox (Allais 1953). Our results help to understand the reliability and robustness of investigations into the actual distribution of risk preferences in populations.Our research strategy is threefold. First, we implement three different treatments in the main experiment with the panel. We analyze the original Allais question with payoffs of millions of Euros that, just as when Allais asked Savage, were purely hypothetical. In our second treatment we scaled the payments down but kept them hypothetical. Our third treatment used the same downscaled payoffs but paid them out for real. This enables us to examine to what extent violations are driven by lack of monetary incentives, on the one hand...
