报告摘要:

Surveys that measure subjective states like happiness or preferences often generate ordinal data. Ordered response models, which are commonly used to analyze such data, suffer from a fundamental identification problem. Their conclusions depend entirely on unjustified assumptions about the distribution of a latent variable. In this paper, we propose using survey response times to solve that problem. Response times contain information about the distribution of the latent variable, even among subjects who give the same ordinal survey response. We provide conditions under which group differences in, for example, happiness are identified. We apply our method to an online survey and obtain evidence that happiness follows distributions for which traditional assumptions are valid. The evidence is more mixed for our preference questions, and traditional assumptions are not confirmed for our question about political attitudes.
