Does legalizing retail marijuana generate more benefits than costs? This paper provides a first step toward addressing that question by measuring the benefits and costs that are capitalized into housing values. We exploit the time‐series and cross‐sectional variations in the adoption of Colorado's municipality retail marijuana laws (RMLs) and examine the effect on housing values with a difference‐in‐differences strategy. Our estimates show that the legalization leads to an average 6% increase in housing values, indicating that the capitalized benefits outweigh the costs. In addition, we find suggestive evidence that this relatively large housing value appreciation is likely due to RMLs inducing strong housing demand while having no discernible effect on housing supply. Finally, we show that the effect of RMLs is heterogeneous across locations and property types. (JEL K20, R28)

Home appraisal came under scrutiny for contributing to the home‐price bubble and enabling the origination of risky mortgages that led to the post‐2006 foreclosure crisis. Subsequent regulations tried to minimize or eliminate conflicts of interest and improve valuations. Nonetheless, our study of appraisals completed in 2015 and 2016 find that appraisal bias still occurred. Our analysis delves into the underlying appraisal development to identify causes of appraisal bias. Contributing factors are that comps are generally higher valued than the subject property, and appraisers are more likely to comparatively adjust upward lower priced comps but less likely to adjust downward higher priced comps.
