We use a public referendum on a new aviation concept in Berlin, Germany, as a natural experiment to analyze how the interaction of tenure and capitalization effects influences the outcome of direct democracy processes. We distinguish between homevoters, i.e., voters who are homeowners, and leasevoters, i.e., voters who lease their homes. We expect that homevoters would be more likely to support initiatives that positively affect the amenity value of a neighborhood because some of the related benefits of leasevoters are neutralized by adjustments in market rents. Likewise, homevoters would be more likely to oppose initiatives that negatively affect the amenity value of a neighborhood. Our empirical results are consistent with these expectations, implying that public votes on local public goods do not necessarily reflect the spatial distribution of welfare effects in mixed-tenure environments.
