Behavioral economics has the potential to inform the design of incentives to improve disease screening programs by accounting for various behavioral biases. We investigate the association between multiple behavioral economics concepts and the perceived effectiveness of incentive strategies for behavioral change among older patients with a chronic disease. This association is examined by focusing on diabetic retinopathy screening, which is recommended but very variably followed by persons living with diabetes. Five time and risk preference concepts (i.e., utility curvature, probability weighting, loss aversion, discount rate, and present-bias) are estimated simultaneously in a structural econometric framework, based on a series of deliberately-designed economic experiments offering real money. We find that higher discount rates and loss aversion and lower probability weighting are significantly associated with lower perceived effectiveness of intervention strategies whereas present-bias and utility curvature have an insignificant association with it. Finally, we also observe strong urban vs. rural heterogeneity in the association between our behavioral economic concepts and the perceived effectiveness of intervention strategies.
行为经济学有潜力通过考虑各种行为偏差来为改善疾病筛查项目的激励措施设计提供信息。我们研究了多个行为经济学概念与慢性病老年患者行为改变激励策略的感知有效性之间的关联。通过关注糖尿病视网膜病变筛查来检验这种关联，糖尿病视网膜病变筛查虽有推荐，但糖尿病患者的遵循情况差异很大。基于一系列提供真钱的精心设计的经济实验，在一个结构计量框架中同时估计五个时间和风险偏好概念（即效用曲率、概率加权、损失厌恶、贴现率和现状偏差）。我们发现，较高的贴现率和损失厌恶以及较低的概率加权与干预策略的较低感知有效性显著相关，而现状偏差和效用曲率与之关联不显著。最后，我们还观察到我们的行为经济学概念与干预策略的感知有效性之间的关联存在强烈的城乡异质性。
