共享出行与经济活动的再分配
Ridesharing and the redistribution of economic activity
摘要
This paper studies how improvements in local accessibility influence cities’ distributions of nontradable amenities, housing costs and welfare. I build a model of local demand for these amenities, which depends on travel times and costs. Ridesharing’s entry shocks these times and costs. Three years after entry, amenities grow faster in areas which are driving-accessible and transit-inaccessible. In these locations, house prices and rents rise by 7% and 2% after three years, respectively. Taken together, the improvements in amenities and access outpace the rising housing costs. All residents benefit from ridesharing; yet, owners gain 24% more than renters on average, as they capture equity gains from rising house prices while renters face higher housing costs.

本文研究了本地可达性的改善如何影响城市的非贸易性便利设施分布、住房成本与福利。我构建了一个对这些便利设施的本地需求模型，该需求取决于出行时间与成本。拼车服务的进入冲击了这些时间与成本。进入三年后，在驾车可达且公共交通不可达的区域，便利设施增长更快。在这些地点，三年后房价与租金分别上涨了7%和2%。综合来看，便利设施与可达性的改善超过了住房成本的上升。所有居民均从拼车服务中受益；然而，业主平均比租户多获益24%，因为他们从房价上涨中获得了资产增值收益，而租户则面临更高的住房成本。
