Title:In: When Does Incentivization Matter For Preference Measurement? Evidence from Repeated Social Value Orientation Elicitation
Abstract: Are incentivized and non-incentivized implementations of the same preference measure comparable? We study repeated elicitation of Social Value Orientation (SVO) in a two-wave laboratory design with randomized incentive regimes, with the two measurement occasions approximately three months apart. Incentivization shifts the distribution of SVO types toward individualism and makes repeated measurements of the same individual agree more closely. The probability of retaining the same SVO type across waves increases by about 26 percentage points. Internal consistency remains high in both regimes. We cannot statistically detect an overall improvement in predictive validity, although the point estimate for the structurally closest task, the dictator game, suggests a substantially steeper predictive slope under incentivization. Incentive regimes are therefore not measurement-neutral for SVO.
