If We Build it,Will They Pay? Predicting Property Price Effects of Transport Innovations

In this study I apply a gravity-type labor-market accessibility model to the Greater London Area to investigate house price capitalization effects. The spatial scope of labor-market effects is found to be about 60 minutes. Doubling accessibility increases the utility of an average household by about 12%. I combine the gravity approach with a transport decision model that takes into account the urban rail network architecture, allows for mode switching, and thus accounts for the effective accessibility offered by a station, to predict the property price effects of the 1999 Jubilee Line and DLR extension. A considerable degree of heterogeneity is predicted both in terms of the magnitude as well as the spatial extent of price effects around new stations. A quasi-experimental property price analysis reveals that the model performs well in predicting the effective capitalization effects, suggesting that the approach might be a viable ingredient in transport planning.
