The Geography of Public Housing and the Dynamics of City Structure (with David Jinkins and Ismir Mulalic)
Abstract: This paper examines how public housing interacts with the dynamics of city structure. Exploiting individual-level panel data from Denmark along with a large-scale quasi-experimental privatization of public housing in Copenhagen, we document the effects of public housing on city structure. We develop and estimate a dynamic quantitative urban model with both publicly allocated and private housing as well as endogenous amenities and find that reductions in public housing substantially amplify gentrification patterns, altering household sorting, housing prices, and local amenities.
How Inefficient Are Local Government Boundaries? A Quantitative Analysis of Denmark
Abstract: This paper studies the general-equilibrium welfare effects of local government boundaries in real-world geographies. It leverages quasi-experimental variation from Denmark’s 2007 structural reform, which simultaneously and comprehensively altered municipal boundaries and with them local tax bases, expenditure needs, and political composition. Using this variation to identify the key parameters, it estimates a quantitative spatial model with endogenous local fiscal policies, housing markets, and residential sorting. Combining a partial search over feasible maps with a spatially unconstrained club-theoretic benchmark, the analysis bounds the welfare losses from observed boundaries from below and above.
