The relationship between neighborhood design and social capital as measured by carpooling
利用加州地理编码调查数据，以拼车作为社会资本的代理变量，研究死胡同式邻里设计是否影响社会资本，发现设计效应在考虑居住自选择后不再显著。
Abstract This paper examines whether social capital in a neighborhood is influenced by its design, taking the cul‐de‐sac as a special case. It offers two contributions: using carpooling to school as a proxy for social capital and a precise definition of the neighborhood using geo‐coded survey data from California. Living in a cul‐de‐sac neighborhood is found to increase the probability of carpooling, but the effect loses statistical significance when residential self‐selection is accounted for. The analysis reveals competing insights about the self‐selection behavior that must be resolved before neighborhood design can be considered an effective policy tool for enhancing social capital.
