中文摘要
本文研究城市内部的本地食品杂货市场如何受到住房市场变化的影响。我们的实证策略利用了蒙得维的亚市一项大规模、基于地域的税收减免政策所引致的建筑活动空间分布变化。该政策带来的新增住房存量使食品杂货价格下降2.3%，并增加了本地可获得的产品种类。结合不完全竞争多产品模型的见解以及对不同类型商店的估计结果，我们表明这些变化是既有商户对本地需求增加做出反应的结果。（JEL L81, O18, R22, R23, R31, R38）
Abstract
We study how local grocery markets within a city are affected by changes in housing markets. Our empirical strategy exploits a shift in the spatial distribution of construction activity induced by a large-scale, place-based tax exemption in the city of Montevideo. The introduction of new housing stock induced by the policy causes a reduction in grocery prices of 2.3 percent and an increase in locally available product varieties. Using insights from a multiproduct model of imperfect competition and estimates for different types of stores, we show these changes are the result of incumbents’ response to an increase in local demand.
