On Thursday, November 17, noon-14 pm, Wenying Yao from Deakin University will be the speaker of the Research Seminar in Economics. She will present her research paper on "High-dimensional predictive regression in the presence of cointegration" at Kaminzimmer (room 202), Boltzmannstraße 20, Berlin-Dahlem.
Pollution and city size: Can cities be too small?
Abstract: We study the optimal and equilibrium size of cities in a monocentric city model with environmental pollution. Pollution is related to city size through the effect of population on production, commuting, and housing consumption. With symmetric cities, if pollution is local or per capita pollution increases with population, we find that equilibrium cities are too large. When pollution is global and per capita pollution declines with city size, however, equilibrium cities may be too small. With asymmetric cities, the largest cities are too large and the smallest too small when pollution is local or per capita pollution increases with population; when pollution is global and per capita pollution decreases with population, the largest cities are too small and the smallest too large. We also calibrate the model to US MSAs and find that the largest cities may be undersized by 3-4%.
