We propose a search and matching model of the urban network. When geography is fixed and the job finding rate decreases with distance, the interplay between firm entry and worker migration generates an equilibrium allocation in which productive agents cluster in a few large central cities where matching is more assorted and profitable, while many small peripheral cities retain low-skilled workers. Counterfactual experiments suggest that (i) small transfers to the periphery hurt everyone, while large transfers can achieve a more efficient, decentralized organization; (ii) lower frictions deconcentrate the network and benefit everyone.

We propose an analytical solvable model for household residential location choice in a linear monocentric city corridor with bottleneck congestion. Households are heterogeneous in terms of their income. The bottleneck is located between central downtown and adjacent suburb. The urban equilibrium is formulated as the solution of differential equations. We analytically explore the distributional effects of bottleneck capacity expansion on households and the bottleneck capacity investment issues under no toll and first-best and second-best tolls. The results show that the benefits of different-income households from bottleneck capacity expansion change with toll schemes. Specifically, under the no toll and first-best toll, those who gain most are the mid-income households residing at the bottleneck and in a suburban location (close to the bottleneck) respectively, whereas those who gain least are the poorest or richest households. Under the second-best toll, there are two possible cases: the poorest households gain most while the richest households gain least, or the mid-income households residing at the bottleneck gain most while the richest or poorest households gain least. With constant return to scale for capacity investment, self-financing principle still holds for the first-best and second-best tolling in the urban spatial context. Ignoring the changes in urban spatial structure due to household relocation may cause overinvestment or underinvestment in optimal bottleneck capacity under the no toll, but definitely underinvestment under the first-best and second-best tolls.

We examine the effect of real estate owned property rehabilitations on neighboring property prices. We find that house prices around a rehabilitated property increase 2.3 percentage points following the rehabilitation. Moreover, the average rehabilitation generates aggregate welfare benefits 3.8 times greater than the amount invested. Rehabilitation externalities are stronger for longer rehabilitations and greater rehabilitation investments, and they are prevalent even in areas with high rates of foreclosures. The spillover effect of rehabilitations operates through their salience rather than through a reduction in the supply of distressed properties, through property appraisals, or through homebuyers with higher income moving into the neighborhood.

This article examines the spillover effects of neighboring firms’ imports on the productivity of non-importers. By analyzing geocoded manufacturing firms in China, we find that capital goods imports by neighboring firms within 10 km positively impact non-importer productivity; intermediate goods imports show no clear spillover. These results hold when using imports from distant firms as instruments. Spillovers from capital imports mainly come from neighbors in upstream and downstream industries, which indicate potential supply chain effects. Learning effects from neighboring imported products are not significant. Quantitatively, neighboring capital imports raised non-importers’ average productivity by 0.99% from 2000 to 2006, surpassing gains from their own R&D participation by more than sixfold. Overall, our findings demonstrate substantial societal benefits of capital imports for non-importers connected spatially.

This paper examines the effects of relaxing land-use regulations on housing supply and rents at the local intra-city level. We apply a staggered difference-in-difference model, exploiting exogenous differences in the treatment timing of zoning plan reforms as identifying variation. Increasing the allowable floor-to-area ratio (FAR), i.e., upzoning, significantly increases the living space and housing units by approximately 9% in the subsequent five to ten years. This effect is stronger for larger upzonings, for rasters where zoning is binding, and where rents are high. Furthermore, upzoning leads to no difference in hedonic rents between upzoned and later-upzoned rasters. These results show that upzoning is a viable policy for increasing housing affordability. However, the effects depend on the upzoning policy design and take several years to materialize.

This paper investigates the reversibility of the effects of transport infrastructure investments, based on a programme that removed much of the rail network in Britain during the mid-20th century. We find that a 10% loss in rail access between 1950 and 1980 caused a persistent 3% decline in local population relative to unaffected areas, implying that the 1 in 5 places most exposed to the cuts saw 24 percentage points less population growth than the 1 in 5 places that were least exposed. The cuts reduced local jobs and shares of skilled workers and young people.
