In situations of poverty, do people take more or less risk? One hypothesis states that poverty makes people avoid risk, because they cannot buffer against losses, while another states that poverty makes people take risks, because they have little to lose. Each hypothesis has some previous empirical support. Here, we test the 'desperation threshold' model, which integrates both hypotheses. We assume that people attempt to stay above a critical level of resources, representing their 'basic needs'. Just above this threshold, people have much to lose and should avoid risk. Below, they have little to lose and should take risks. We conducted preregistered tests of the model using survey data from 472 adults in France and the UK. The predictor variables were subjective and objective measures of current resources. The outcome measure, risk taking, was measured using a series of hypothetical gambles. Risk taking followed a V-shape against subjective resources, first decreasing and then increasing again as resources reduced. This pattern was not observed for the objective resource measure. We also found that risk taking was more variable among people with fewer resources. Our findings synthesize the split literature on poverty and risk taking, with implications for policy and interventions.
在贫困情况下,人们会承担更多还是更少的风险呢?一种假设认为,贫困会使人们规避风险,因为他们无法缓冲损失;而另一种假设则认为,贫困会使人们冒险,因为他们没什么可失去的。每种假设都有一些先前的实证支持。在此,我们检验“绝望阈值”模型,该模型整合了这两种假设。我们假定人们试图维持在一个关键的资源水平之上,这个水平代表他们的“基本需求”。刚好高于这个阈值时,人们有很多可失去的东西,应该规避风险。低于这个阈值时,他们没什么可失去的,应该冒险。我们使用来自法国和英国472名成年人的调查数据对该模型进行了预注册测试。预测变量是当前资源的主观和客观衡量指标。冒险行为通过一系列假设性赌博来衡量。冒险行为与主观资源呈V形关系,随着资源减少,先是下降,然后再次上升。对于客观资源衡量指标,未观察到这种模式。我们还发现,资源较少的人群中冒险行为的变异性更大。我们的研究结果综合了关于贫困与冒险行为的零散文献,对政策和干预措施具有启示意义。
