Place Based Policies, Heterogeneity, and Agglomeration
研究了政府为何补贴企业迁往低生产率地区并激励工人迁入不喜欢的社区，以及这些补贴在一般均衡中谁最终受益，结论取决于人口偏好异质性和集聚经济结构。
Place based policies, though hardly new, have just begun to attract serious attention from econ omists.' As evidence on the effects of these pro grams begins to trickle in, it is useful to revisit the theoretical rationale for spatially targeted subsidies. Why after all should governments pay firms to move to less productive areas and incentivize workers to live in neighborhoods they don't like? And who ultimately benefits from these subsidies in a general equilibrium environment? I study here some stylized models of spatial equilibrium designed to answer these questions. My conclusions are shown to depend critically upon the degree of preference hetero geneity in the population and the structure of any agglomeration economies.
