Homeowner Subsidy Repeal and Housing Recentralization
利用德国2005年房主补贴改革，通过准实验方法检验取消补贴对城市空间结构的影响，发现补贴取消促进了城市再中心化，并可能有助于减少碳排放。
<h3>Abstract</h3> Subsidizing homeownership decentralizes cities, so Muth (1967) suggested over half a century ago. This paper’s interest is in the related question of whether repealing a homeownership subsidy recentralizes cities. This question is relevant today, given homeownership subsidies’ ubiquity. We provide a first quasi-experimental test of a subsidy repeal’s spatial effects by turning to Germany’s 2005 homeownership subsidy reform. We find that repealing the subsidy contributed to recentralizing Germany’s cities. Inasmuch as recentralization helps abate carbon dioxide emissions, repealing a homeownership subsidy also helps mitigate global warming.
