The problem of evil: An economic approach
用经济学模型研究哲学中的恶的问题，将上帝创世视为最优激励问题，发现恶能内生地使人类行为符合神的仁慈目标。
Abstract This paper develops an economic model to study the philosophical problem of evil. God's creation of the world is modeled as a problem of optimal incentives. A principal (God) must choose a world so that the populating agents behave according to his benevolent objective. In a world, the physical environment resembles a contract that determines the rewards and punishments for different choices. The agents' behavioral rule determines how they respond to these incentives. I characterize a contract and a behavioral rule that solve the principal's problem, and evil is evidenced. Specifically, evil endogenously aligns the agents' actions with the principal's objective. Other insights on the origin, cause, and role of evil are also derived from the model. The result of this analysis is a theodicy arisen from an economic model. As a byproduct, this paper shows how an economic model can be used to study philosophical or theological questions.
