Dynamic Logit With Choice Aversion
推广了折扣Logistic选择模型，引入参数刻画决策者对更大选择集的不同态度，从偏好灵活性到不同程度的选择厌恶，并发现选择厌恶越强，决策者越倾向于推迟决策。
We characterize a generalization of discounted logistic choice that incorporates a parameter to capture different views the agent might have about the costs and benefits of larger choice sets. The discounted logit model used in the empirical literature is the special case that displays a “preference for flexibility” in the sense that the agent always prefers to add additional items to a menu. Other cases display varying levels of “choice aversion,” where the agent prefers to remove items from a menu if their ex ante value is below a threshold. We show that higher choice aversion, as measured by dislike of bigger menus, also corresponds to an increased preference for putting off decisions as late as possible.
