Costly Commuting and the Job Ladder
Even though workers in the UK spent just 1,000 pounds on commuting in 2017, the economic loss may be far higher because of the congestion externality arising from the way in which one worker's commute affects the commuting time of others. I provide empirical evidence that commuting time affects job acceptance, pointing to large indirect costs of congestion. To interpret the empirical facts and quantify the costs of congestion, I build a model featuring a frictional labor market within a metropolitan area. By endogenizing commuting congestion in a labor search model, the model connects labor ...

The Environmental Cost of Land Use Restrictions
Cities with cleaner power plants and lower energy demand have stricter land use restrictions; these restrictions increase housing prices and disincentivize living in these lower polluting cities. We use a spatial equilibrium model to quantify the effect of land use restrictions on household carbon emissions. Our model features heterogeneous households, cities that vary by power plant technology and the benefits of energy usage, as well as endogenous wages and rents. Relaxing restrictions in California to the national median leads to a 2.3% drop in national carbon emissions. The burden of a ...

The Case of the Reappearing Phillips Curve: A Discussion of Recent Findings
The Phillips curve seems to have flattened over time. In this article, we use a simple New Keynesian model to analyze potential pitfalls in the estimation of the slope of the structural Phillips curve.

Commuting, Labor, and Housing Market Effects of Mass Transportation: Welfare and Identification
REVISED MARCH 2019 This paper studies the effects of Los Angeles Metro Rail on the spatial distribution of people and prices. Using a panel of bilateral commuting flows, I estimate a quantitative spatial general equilibrium model to quantify the welfare benefits of urban rail transit and distinguish the benefits of reduced commuting frictions from other channels. The subway causes a 7%-13% increase in commuting between pairs of connected tracts; I select plausible control pairs using proposed subway and historical streetcar lines to identify this effect. The structural parameters of the model ...

Location as an Asset
The location of individuals determines their job opportunities, living amenities, and housing costs. We argue that it is useful to conceptualize the location choice of individuals as a decision to invest in a ?location asset?. This asset has a cost equal to the location?s rent, and a payoff through better job opportunities and, potentially, more human capital for the individual and her children. As with any asset, savers in the location asset transfer resources into the future by going to expensive locations with good future opportunities. In contrast, borrowers transfer resources to the ...

Migration, Congestion Externalities, and the Evaluation of Spatial Investments
The direct benefits of infrastructure in developing countries can be large, but if new infrastructure induces in-migration, congestion of other local publicly provided goods may offset the direct benefits. Using the example of rural household electrification in South Africa, we demonstrate the importance of accounting for migration when evaluating welfare gains of spatial programs. We also provide a practical approach to computing welfare gains that does not rely on land prices. We develop a location choice model that incorporates missing land markets and allows for congestion in local land. ...

Domestic vs. International Welfare Gains from Trade
Using varieties of a rich model that considers sectoral heterogeneity and input-output linkages, this paper shows that the overall welfare gains of a region within a country can be decomposed into domestic versus international welfare gains from trade. Empirical results based on state-level data from the U.S. suggest that about 91 percent of the overall welfare gains of a state are due to domestic trade with other states, on average across alternative model specifications, with a range between 72 percent and 99 percent across states. When national-level data are used for the U.S., ...

Social Transfers and Spatial Distortions
US social transfer programs vary substantially across states, incentivizing households to locate in states with more generous transfer programs. Further, transfer formulas often decrease in income, therefore rewarding low-income households for living in low-paying cities. We quantify these distortions by combining a spatial equilibrium model with a detailed model of transfer programs in the US. The current system leads to locational inefficiency of 4.38% of total transfer spending. A reform that both harmonizes transfer policies across states and indexes household income to local average ...

Spoils of War: Trade Shocks and Segmented Labor Markets in Spain during WWI
How does intranational factor mobility shape the welfare effects of a trade shock? I provide evidence that during WWI, a demand shock emanated from belligerent countries and affected neutral Spain. Within Spain, labor predominantly reallocated locally, while the most affected provinces experienced drastic increases in wages and consumer prices. Embedding imperfect labor mobility in an economic geography model, I show that external demand shocks can improve allocative efficiency, but asymmetric shocks cause localized increases in wages and consumer prices instead of reallocation. Adjusting an ...

Discrete Choice, Complete Markets, and Equilibrium
This paper characterizes the allocations that emerge in general equilibrium economies populated by households with preferences of the additive random utility type that make discrete consumption, employment or spatial decisions. We start with a complete markets economy where households can trade claims contingent upon the realizations of their preference shocks. We (i) establish a first and second welfare theorem, (ii) illustrate that in the absence of ex-ante trade, discrete choice economies are generically inefficient, (iii) show that complete markets are not necessary and a much smaller set ...
