- We provide evidence that choices over small stakes bets are consistent with assumptions of some payoff calibration paradoxes. We then exploit the existence of detailed information on individual wealth of our experimental subjects in Denmark, and directly estimate risk attitudes and the degree of asset integration. We discover that behavior is consistent with partial, rather than full, asset integration. The implied risk attitudes from estimating these specifications indicate risk premia and certainty equivalents that are a priori plausible. This theory and evidence suggest one constructive solution to payoff calibration paradoxes.

Measuring Risk Aversion to Guide Policy : Naturalistic Tasks and Respondents
- 2013
-
Konferensbidrag (refereegranskat)abstract
- When measuring risk attitudes for use in policy analysis it is important to recognize that the context may matter. We propose a method that goes beyond simple context framing using text and pictures and instead relies on Virtual Reality simulations. Such simulations have been shown to improve the accuracy of perceptions in experimental context. We ask whether elicited risk preferences differ when using simulations or stylized lottery tasks, and compare students (a low cost convenient subject pool) to field subjects. While we see initial differences across our 2x2 treatment design, we find that they converge with repetition.

- Road pricing may provide a solution to increasing traffic congestion in metropolitan areas. Route, departure time and travel mode choices depend on risk attitudes as commuters perceive the options as having uncertain effects on travel times. We propose that Experimental Economics methods can deliver data that uses real consequences and where the context can be varied by the researcher. The approach relies on the controlled manipulation of contexts, similar to what is done in the Stated Choice approach, but builds in actual consequences, similar to the Revealed Preference approach. This paper investigates some of the trade-offs between the cost of conducting Experimental Economics studies and the behavioral responses elicited. In particular, we compare responses to traditional lottery choice tasks to the route choice tasks in simulated driving environments. We also compare students (a low cost convenient participant pool) to field participants recruited from the driving population. While we see initial differences across our treatment groups, we find that their risk taking behavior converge with minimal repetition.

Methodologic support in habilitation and rehabilitation: communicative action between practice and science
- 2000

Tidskriftsartikel (refereegranskat)abstract
- This study evaluated the early phase of development of a model for quality improvement of habilitation and rehabilitation project processes. The focus of the methodologic support in habilitation and rehabilitation model was on cooperation between practice contexts and science. Habermas' theory about communicative action was a theoretical frame of reference. Three project coordinators and ten project leaders were interviewed. The results revealed different attitudes towards methodologic support activities, demonstrating the importance of acknowledging cognitive and social functions, the process of legitimization, different approaches of practice versus science, and problems regarding information and communication. The model was shown to be important in bridging the gap between practice and science. To support reflective and emancipatory cognitive learning, more efforts to foster communicative action are called for, and more attention must be paid to the importance different missions and organizational structures have for the development of the dialog between practitioners and researchers.
