MEASURING ECONOMIC INSECURITY
用公理化的方法衡量经济不安全感,认为个人不安全感取决于当前财富水平(作为应对不利事件的缓冲储备)和过去经历的财富波动(影响对未来损失的信心),并基于直观的公理刻画了两类线性测度及其重要子类。
We provide an axiomatic treatment of the measurement of economic insecurity, assuming that individual insecurity depends on the current wealth level and its variations experienced in the past. The first component plays the role of a buffer stock to rely on in case of an adverse future event. The second component determines the confidence an individual has on her ability to overcome a loss in the future. Two classes of linear measures are characterized with sets of plausible and intuitive axioms and, for each of these classes, an important subclass is identified.
