We analyze how the introduction of congestion charges in Gothenburg, Sweden, in 2013 affected the prices of condominiums. Using both a hedonic difference-in-difference (DiD) price regressions and the regression discontinuity design (RDD) approach we find robust evidence that the congestion charges made condominiums inside the toll zone less attractive. For instance, the findings from the DiD suggest a negative price impact on condominiums within the zone by about 6 percent compared to the control group (condominiums in Gothenburg outside the toll zone). The conclusion is that there is strong evidence that the congestion charges had a negative effect on property prices within the toll zone in Gothenburg. This can be explained by relatively small positive effects on traffic volumes and the environment within the zone.
