Effects of Housing Codes on Local Housing Markets
研究北卡罗来纳州城市数据发现，实施住房法规的城市平均居住密度更高，低收入家庭住房拥有率更低，但对房价和支出无显著影响，表明法规迫使消费者以住房数量换取质量。
Housing codes are typically instituted in order to raise the average level of housing quality in a community. However, in doing so, the institution of a housing code likely has effects on other housing characteristics. Using data from municipalities in North Carolina, this study finds that municipalities with housing codes have higher average occupancy densities among all households and lower homeownership rates among low‐income households, but housing codes have no statistically discernible effect on housing values and expenditures. The results suggest that housing codes are not costless; most importantly, codes force consumers to trade housing quantity for quality.
