摘要: We use a frictionless neoclassical general-equilibrium model to explain cross-metro variation in population density based on three broad amenity types: quality of life, productivity tradables, and non-tradables. Analytically, we demonstrate the dependence quantities amenities through substitution possibilities consumption production. Our calibrated predicts large elasticities, consistent with U.S. data, estimates local labor supply demand. From only differences wages housing costs, half density, especially life amenities. also show that information can provide or refine measures land value productivity. approach be used study wide variety urban quantities.
