This chapter surveys the theoretical and empirical literature on the relationship between the
spatial distribution of economic activity and transportation costs. We develop a multiregion …

How would the shape of our cities change if there were a permanent increase in working
from home? We study this question using a quantitative model of the Los Angeles …

We study the impact of widespread adoption of work-from-home (WFH) technology using an
equilibrium model where people choose where to live, how to allocate their time between …

High skilled workers gain from face to face interactions. If the skilled can move at higher
speeds, then knowledge diffusion and idea spillovers are more likely to reach greater …

We study state taxes as a potential source of spatial misallocation in the US. We build a
spatial general equilibrium framework that incorporates salient features of the US state tax …

This paper synthesises the state of knowledge on the economic effects of density. We
consider 347 estimates of density elasticities of a broad range of outcomes ranging from …

Each year in the US, hundreds of billions of dollars are spent on transportation infrastructure
and billions of hours are lost in traffic. We develop a quantitative general equilibrium spatial …

We provide an integrated treatment of the theoretical literature on urban land use inspired by
the monocentric model, including extensions that deal with multiple endogenous business …

We estimate the effect of interstate highways on the level and composition of trade for US
cities. Highways within cities have a large effect on the weight of city exports with an …

We investigate the effect of subway system openings on urban air pollution. On average,
particulate concentrations are unchanged by subway openings. For cities with higher initial …
