3 Popularity of Holt and Laury (2002)  Google Scholar:  Holt and Laury (2002): 6,350 citations  Eckel and Grossman (2002): 411 citations  DoSpeRT Scale by Weber et al. (2002): 54 citations  JSTOR:  Holt and Laury (2002): 65 citations  Eckel and Grossman (2002): 29 citations  DoSpeRT Scale by Weber et al. (2002): 6 citations GvPGvP

4 Virtues and Vices  Virtues:  please the referees  cheap and easy to implement  “relative” flavor  Vices:  not much heterogeneity in the data (majority of participants “slightly risk averse”/ “risk averse”)  inconsistent participants cannot be classified  may produce results that are not robust  assumes CRRA utility function GvPGvP

12 Possible Explanations and Questions  Incentives  “Risk” overconfidence  People do not have CRRA utility function Which measure has an impact on behavior: HL or SR? GvPGvP Which measure provides a “correct” representation of individual risk attitude?
