Urban Growth Shadows
Does a location's growth benefit or suffer from being geographically close to large economic centers? Spatial proximity may lead to competition and hurt growth, but it may also generate positive spillovers and enhance growth. Using data on U.S. counties and metro areas for the period 1840?2017, we document this tradeoff between urban shadows and urban spillovers. Proximity to large urban centers was negatively associated with growth from 1840 to 1920, and positively associated with growth after 1920. Using a two-city spatial equilibrium model with intra-city and inter-city commuting, we show ...
A quantitative system of monocentric metros
The monocentric city framework is generalized to comprise a system of metros. A "representative" closed metro calibrates parameters and establishes a reservation utility and perimeter land price that must be matched by open metros. The open metros are assumed to have exogenous productivity below and above that in the representative metro. For a given level of productivity, transportation technology proves to be the most important quantitative determinant of population, land area, population density, and house prices across and within metros. Changes in highway capacity primarily affect ...
