英文文献摘要:
This paper develops and empirically evaluates alternative econometric strategies for accounting for non-participation - repeated choice of the same alternative or same type of alternative - in data sets that are typically analyzed within the repeated discrete choice framework. Random coefficient single and double hurdle variants of the repeated discrete choice model are developed and applied to stated preference data. The empirical results suggest that significant statistical improvements in fit can arise with the single and double models relative to more traditional models. However, similar to Haab and McConnell's (1996) findings in the context of count data models, these gains are diminished when the analyst accounts for unobserved heterogeneity through random coefficients.
本文在重复离散选择框架下分析的数据集中,发展并实证评估了计量经济学的替代策略,以解释不参与-重复选择相同的选择或相同类型的选择。建立了重复离散选择模型的随机系数单栏变量和双栏变量,并将其应用于指定的偏好数据。实证结果表明,与传统模型相比,单模型和双模型在拟合方面有显著的统计改进。然而,类似于Haab和McConnell(1996)在计数数据模型背景下的发现,当分析人员通过随机系数考虑到未观察到的异质性时,这些收益会减少。
