This paper applies a variation on differences-in-differences to the effects of economic freedom in matched bordering metropolitan statistical areas using the Metropolitan Economic Freedom Index. While a great deal of research has explored the relationship between economic freedom and economic performance, less has been done at the local level. We find that economic freedom has a positive effect on several measures of economic performance, but no effect on population.

大都市统计区边界的经济自由

本文使用大都市经济自由指数，将差异中的差异应用于匹配的大都市统计区域中经济自由的影响。虽然大量研究探索了经济自由度与经济绩效之间的关系，但在地方层面所做的研究较少。我们发现经济自由度对经济绩效的多项指标有积极影响，但对人口没有影响。
