Flooding risks and housing markets: a spatial hedonic analysis for La Plata City

Abstract

Abstract: On 2 April 2013 a major flood struck the City of La Plata, Argentina, killing 89 people and displacing thousands of others. That event, the worst flood the city has suffered in the past 100 years, prompted plans for a new hydraulic infrastructure. Although such an investment is necessary, little is known about its benefits. This paper intends to shed some light on this issue by estimating the willingness to pay to avoid the risk of experiencing a flooding event. For this purpose, we have taken thousands of real estate prices in the La Plata Metropolitan Area and combined them with a high-resolution flood risks map to estimate spatial hedonic price models. The results show significant price discounting for properties in flood-prone areas.
