摘要

与COVID-19大流行的各个方面相关的已发表的选择实验在快速审查中进行分析。其目的是(i)记录主题的多样性及其出现的时间和地理模式,(ii)比较应用经济学不同部门的设计质量的各种要素,以及(iii)确定可比实验结果中收敛效度的潜在迹象。在大流行头两年发表的43项选择实验中,大多数与卫生应用有关(N = 30),其次是与运输相关的应用(N = 10)。全球近10万人参与了与大流行相关的离散选择调查。在卫生应用领域,虽然直到2020年6月,主要主题还是放松封锁和追踪措施,但自那以后,重点突然转移到疫苗偏好上。健康调查的地理来源并不多样化。近50%的健康调查仅在三个国家进行,即美国、中国和荷兰。与运输应用相比,卫生应用表现出更强的预测试和更大的样本量。有限的趋同效度迹象是可识别的。在一些应用中,时间不稳定性问题以及归因于社会可取性、抗议反应或政策后果的假设偏见似乎可能影响了研究结果。然而,很少有实验实施了假设偏差缓解措施,这些措施仅限于健康研究。我们的主要结论是,与流行病相关的选择实验的快速管理总体上导致了研究质量在一定程度上的妥协,但这种情况在交通主题方面比健康主题更为明显。

Applications of discrete choice experiments in COVID-19 research: Disparity in survey qualities between health and transport fields

Published choice experiments linked to various aspects of the COVID-19 pandemic are analysed in a rapid review. The aim is to (i) document the diversity of topics as well as their temporal and geographical patterns of emergence, (ii) compare various elements of design quality across different sectors of applied economics, and (iii) identify potential signs of convergent validity across findings of comparable experiments. Of the N = 43 published choice experiments during the first two years of the pandemic, the majority identifies with health applications (n = 30), followed by transport-related applications (n = 10). Nearly 100,000 people across the world responded to pandemic-related discrete choice surveys. Within health applications, while the dominant theme, up until June 2020, was lockdown relaxation and tracing measures, the focus shifted abruptly to vaccine preference since then. Geographical origins of the health surveys were not diverse. Nearly 50% of all health surveys were conducted in only three countries, namely US, China and The Netherlands. Health applications exhibited stronger pre-testing and larger sample sizes compared to transport applications. Limited signs of convergent validity were identifiable. Within some applications, issues of temporal instability as well as hypothetical bias attributable to social desirability, protest response or policy consequentiality seemed likely to have affected the findings. Nevertheless, very few of the experiments implemented measures of hypothetical bias mitigation and those were limited to health studies. Our main conclusion is that swift administration of pandemic-related choice experiments has overall resulted in certain degrees of compromise in study quality, but this has been more so the case in relation to transport topics than health topics.
