Assessing the Impact of Wildfires on the Swedish Housing Market: a Case Study of the 2014 Västmanland Wildfire
摘要
The literature on wildfires and residential property prices is limited and primarily focuses on events in North America. There is a lack of studies examining this relationship in Europe. With the largest forest area in the entire EU, understanding this impact is particularly relevant in a Swedish context. In this paper, we investigate how the largest wildfire in Sweden’s recent history, the 2014 wildfire in Västmanland County, affected nearby housing prices and time-on-market. Using a difference-in-differences method, we find a significant negative effect on housing prices. Our most conservative estimate indicates an approximate 2.7% reduction in final selling prices for post-fire sales located within 20 km of the wildfire area. However, the negative effect is even larger when defining the treated area as a 5 km (-10.1%) or 10 km (-8.9%) distance to the fire, and these results are confirmed by a repeated sales model that includes only single- and multi-family houses. In a heterogeneity assessment with respect to the housing types, we find that our effects are mostly driven by the impact on single-family houses rather than apartments. For the former group, we find large negative and significant effects, while we fail to detect any significant one on apartments prices. The largest impact on prices occurs in the first months after the event and for those properties that are located along the trajectory of the wildfire’s smoke.
