Would increasing allowable housing densities in expensive cities generate more housing construction and make housing more affordable? In a provocative article, Andrés Rodríguez-Pose and Michael Storper survey the evidence and answer no. Restrictions on housing density, they contend, do not substantially influence housing production or price. They further argue that allowing more density in growing metropolitan areas would only improve housing outcomes for the affluent, and most likely harm the poor. We take issue with both of these contentions. While uncertainties remain in the study of housing prices and land use regulation, neither theory nor evidence warrant dispensing with zoning reform, or concluding that it could only be regressive. Viewed in full, the evidence suggests that increasing allowable housing densities is an important part of housing affordability in expensive regions.
在昂贵的城市里增加允许的住房密度会产生更多的住房建设，并提高住房的客负担性吗？ 在一篇引人深思的文章中，安德烈.罗德里格斯.阿西 (Andre s. Rodrguez-Pose) 和迈克 尔+斯托尔拍 (Michael Storper) 卜祀丨对证据进行了研宄，并给出了否定的答案。他们认为，对 住房密度的限制不会对住房产量或价格产生实质性影响。他们进一步认为，在不断增长 的大都市地区允许更高的密度只会改善富人的住房状况，而且很可能会伤害穷人。我们 不同意这两个观点。尽管在房价和土地使用监管的研宄中仍存在不确定性，但无论是理 论还是证据都不支持取消分区改革，也不认为分区改革只能是倒退。从整体上看，证据 表明提高允许的住房密度是提高昂贵地区住房可负担性的一个重要因素。.
