The price effects of greening vacant lots: How neighborhood attributes matter
研究绿化空地如何影响附近房价，发现房价上涨约4%，且效果在空置率高和收入较高的社区更显著，同时强调样本选择偏差调整的重要性。
Abstract We identify the effects of greening vacant lots on nearby housing prices and show how neighborhood attributes matter to these outcomes. Using data from a longstanding program in Philadelphia, we find that prices for houses within 1,000 feet of a greened vacant lot rise by about 4%, consistent with the literature, with the effect size increasing over time. Using the extensive data available in Philadelphia, we show how these effects vary by the attributes of the neighborhood in which they occur, with larger effects in areas with a high share of vacant land and higher‐than‐average median household incomes, with peak responses estimated at 19% and 15%, respectively. We demonstrate the importance of sample selection bias adjustment for identification of the effect of vacant lot greening.
