ABSTRACT

The handling of unemployment is a central issue in cost–benefit analysis. Typically, the shadow price of employing an unemployed is derived by considering a marginal change in the employment constraint faced by an unemployed or rather an underemployed. In contrast, in this paper, we consider the discrete shift from unemployment to (full) employment. The result provides guidance how to estimate the social cost of recruiting otherwise unemployed to a project. It is shown that the social cost is overestimated by using the private reservation wage. The common practice of adding different cost items is shown to be flawed.

关于失业的社会机会成本

摘要

失业处理是成本效益分析的核心问题。通常，雇用失业者的影子价格是通过考虑失业者或就业不足者所面临的就业约束的边际变化得出的。相比之下，在本文中，我们考虑了从失业到（充分）就业的离散转变。该结果为如何估计招募原本失业的项目的社会成本提供了指导。结果表明，使用私人保留工资高估了社会成本。添加不同成本项目​​的常见做法被证明是有缺陷的。
