A Simple Model of Sectoral Adjustment
提出了一个两部门经济的简单完美预见模型，通过人口变化实现劳动力跨部门调整，可用于分析相对价格冲击对部门调整的影响。
Despite the significance of limited labour mobility across sectors, few attempts have been made to produce dynamic models of sectoral adjustment which are consistent with perfect foresight and, yet, flexible enough to allow for a variety of dynamic experiments. This paper proposes a simple perfect-foresight model of two-sector economies, in which aggregate sectoral movement of labour takes place through the process of demographic change. The model is tractable enough that one can easily examine the effects of intertemporally complicated relative price shocks (both exogenous and endogenous) under a variety of assumptions on technology.
