Congestion charging in London was introduced in February 2003 to reduce traffic levels in the centre of London. Postcode sector level property prices for sectors both inside and outside the zone are investigated under the premise that the benefits of transport innovation can be captured by property prices. If housing markets are efficient, residential property prices should capture all the benefits and costs to commuters that a location offers. The aim of this investigation is to firstly compare property prices inside and outside the congestion charging zone, and secondly to measure the sensitivity of house prices to distance from the zone boundary both inside and outside the zone. The main analysis is based on the quasi-experimental differences-in-differences approach. It is found that the gap between property price inside and outside the zone has actually reduced as a result of congestion charging. Also, after the implementation of the congestion charge, the sensitivity of house prices with respect to distance from the boundary has fallen for sectors inside the zone relative to sectors outside the zone.
