Migration Under Uncertainty: “Try Your Luck” or “Wait and See”
研究了迁移决策中的两类不确定性:当前目的地条件不可观测和未来条件不确定,前者鼓励“碰运气”式迁移,后者则抑制迁移,模型表明未来不确定性对迁移决策影响更大。
Two types of uncertainty enter into the migration decision. First, current conditions in the destination region may not be observable. Second, the future evolution of conditions in both the origin and destination regions may be unknown. The first type of uncertainty can encourage speculative or “try your luck” migration, whereas uncertainty about the future acts in the opposite direction, deterring relocation. This paper presents a dynamic optimizing model of migration that incorporates both types of uncertainty. The model shows that in equilibrium uncertainty about the future is likely to be more important than uncertainty about present conditions in the decision to relocate.
