Removal of stigma: impact on property values

This paper determines the impact, stigma has on property values and how long the stigma remains after the Not in My Back Yard (NIMBY) structure has been removed. A quantitative analysis was undertaken, using a high voltage overhead transmission line (HVOTL) case study, to determine the effect on property values prior and post removal of the NIMBY structure. A repeat sales index in conjunction with the regression analysis determined the length of time; the stigma remained after removal of the NIMBY structure. The results show that while the NIMBY is in place the impact on value is confined to those properties in close proximity. This is in contradiction to the findings, where on removal of the NIMBY the property values of the whole neighbourhood improves with the stigma remaining for 3 to 4 years.
