Abstract

This paper introduces a novel two-level Latent Class (LC) structure to investigate the temporal stability of preferences, allowing individuals to switch classes over time. The model is used to investigate the temporal stability of COVID-19 vaccine preferences in Australia (AUS) and New Zealand (NZ) during 2020-2021. Through online experiments on vaccine choices, stated choice data is collected across three waves from the general population in both countries. The LC estimation identifies three distinct preference classes: an "Impatient" group, with greater sensitivity to waiting time (AUS: 46%, NZ: 31%), a "Price Sensitive" group (AUS: 41%, NZ: 56%), and a "Vaccine Hesitant" group (AUS: 13%, NZ: 13%). Across waves, preferences for COVID-19 vaccines remain stable, with the probability of respondents remaining in the same class over three waves being 0.62 for Australia and 0.61 for NZ. Changes in preferences are significantly linked to variations in individuals' socioeconomic status and COVID-19 policy responses during the survey period.

偏好的时间稳定性：澳大利亚和新西兰的COVID-19疫苗案例

本文介绍了一种新的两级潜在类别（LC）结构来研究偏好的时间稳定性，允许个体随时间切换类别。该模型用于研究2020-2021年期间澳大利亚（AUS）和新西兰（NZ） COVID-19疫苗偏好的时间稳定性。通过关于疫苗选择的在线实验，从这两个国家的普通人群中收集了三波声明的选择数据。LC估计确定了三个不同的偏好类别：“不耐烦”组，对等待时间更敏感（澳大利亚：46%，新西兰：31%），“价格敏感”组（澳大利亚：41%，新西兰：56%）和“疫苗犹豫”组（澳大利亚：13%，新西兰：13%）。在各波中，对COVID-19疫苗的偏好保持稳定，在三波中，澳大利亚和新西兰的受访者保持在同一类别的概率分别为0.62和0.61。在调查期间，偏好的变化与个人社会经济地位的变化和COVID-19政策应对有很大关系。

期刊介绍： Social Science & Medicine provides an international and interdisciplinary forum for the dissemination of social science research on health. We publish original research articles (both empirical and theoretical), reviews, position papers and commentaries on health issues, to inform current research, policy and practice in all areas of common interest to social scientists, health practitioners, and policy makers. The journal publishes material relevant to any aspect of health from a wide range of social science disciplines (anthropology, economics, epidemiology, geography, policy, psychology, and sociology), and material relevant to the social sciences from any of the professions concerned with physical and mental health, health care, clinical practice, and health policy and organization. We encourage material which is of general interest to an international readership.
