Abstract:
The provision of public transportation can improve the accessibility of work opportunities. However, predicting the labor market effects of new transit infrastructure is difficult because of endogenous worker decisions. I examine a large public-transit rail project on the island of Oahu, Hawaii. Using block-level commuter-flow and travel-time estimates, I propose and estimate a quantitative spatial model of location and mode choice for workers. I estimate that the new rail system increases public-transit-mode share and the employment rate but does not reduce the average commute duration, because of endogenous worker sorting. Low-income workers on Oahu capture a significant share of transit's direct benefits because of their relative preference for both transit and the neighborhoods served by rail.
