Is Housing Unaffordable? Why Isn't It More Affordable?
回顾美国过去四十年住房可负担性趋势，发现自有住房并未变得更难负担，但低收入租房者的租金负担显著增加，并分析了收入分布、住房质量、土地使用法规等因素的影响。
This paper reviews trends in housing affordability in the U.S. over the past four decades. There is little evidence that owner-occupied housing has become less affordable. In contrast, there have been modest increases in the fraction of income that the median renter household devotes to housing. We find pronounced increases in the rent burdens for poor households. We explore the low-income rental market in more detail, analyzing the relative importance of changes in the income distribution, in housing quality, land use regulation, and zoning in affecting rent burdens. We also sketch out some policies that might improve housing affordability.
