Recent research indicates that the subjective evaluation of well-being increases when conditions of housing are improved. This suggests that subjective well-being might serve as a useful proxy for characteristics of a home or neighbourhood that are relevant to an occupant, but unobserved by the analyst. In this paper, we assess this idea through analysis of residential property valuation, using a sample of 95,413 respondents matched to house sales for 2000 to 2012 in the North of the Netherlands. Using a spatial econometric approach, we find a significant and positive association between individual and regional subjective well-being and house prices. This suggests that house buyers are willing to pay more for, or that house sellers require greater compensation to sell and move from, properties and areas in which the resident experiences greater happiness. Our study provides the first estimates of the importance of these effects.
