Psychological Effects of Poverty on Time Preferences
通过实验启动贫困相关想法，发现乌干达农民在娱乐与工作选择中更倾向于即时消费娱乐、推迟工作，表明贫困环境通过纯心理渠道影响时间偏好。
Abstract We test whether an environment of poverty affects time preferences through purely psychological channels. We measured discount rates among farmers in Uganda who made decisions about when to enjoy entertainment instead of working. To circumvent the role of economic constraints, we experimentally induced thoughts about poverty-related problems, using priming techniques. We find that thinking about poverty increases the preference to consume entertainment early and to delay work. Using monitoring tools similar to eye tracking, a novel feature for this subject pool, we show that this effect is unlikely to be driven by less careful decision-making processes.
