Experimental evidence on the effect of incentives and domain in risk aversion and discounting tasks
通过实验室实验,检验激励(真实报酬与假设性)和领域(货币与环境物品)对风险厌恶和折现任务的影响,发现激励平均影响很小,但领域效应显著。
Abstract Environmental policy evaluation is often criticised for employing discount rates that have little grounding in research. Yet, experimental research aimed at eliciting realistic rates will inevitably require strong assumptions of external validity, while also placing large cognitive demands on subjects by processing tasks of increased unfamiliarity. We use a controlled lab experiment to test the impact of incentives on risk aversion and discounting tasks for monetary and environmental goods. We find that, on average, incentives have little effect on risk aversion or discounting tasks in either domain. Exploring heterogeneity by treatment and socio-demographics some significant patterns emerge. Further, contrary to past work, we find evidence of domain (monetary vs . environmental good) effects in both risk and discounting.
