# Literature Request: how does the house quality distribution change endogenously over time?

Is there existing literature on how the distribution of housing quality changes with time? For example, literature saying "using 2000 as a baseline distribution $X$, the housing quality distribution is $1.2X$ in years when GDP is rising and $0.8X$ in years when GDP is decreasing." This is of course very naive, but hopefully it gets my point across. Perhaps housing price distribution could be used as a proxy for house quality, as there may not be data on the latter.
