September 2018The Making of the Modern Metropolis: Evidence from London
with Stephan Heblich, Stephen J. Redding: w25047
Using newly-constructed spatially-disaggregated data for London from 1801-1921, we show that the invention of the steam railway led to the first large-scale separation of workplace and residence. We show that a class of quantitative urban models is remarkably successful in explaining this reorganization of economic activity. We structurally estimate one of the models within this class and find substantial agglomeration forces in both production and residence. In counterfactuals, we find that removing the entire railway network reduces the population and the value of land and buildings in London by up to 51.5 and 53.3 percent respectively, and decreases net commuting into the historical center of London by more than 300,000 workers.

July 2014The Economics of Density: Evidence from the Berlin Wall
with Gabriel M. Ahlfeldt, Stephen J. Redding, Nikolaus Wolf: w20354
This paper develops a quantitative model of internal city structure that features agglomeration and dispersion forces and an arbitrary number of heterogeneous city blocks. The model remains tractable and amenable to empirical analysis because of stochastic shocks to commuting decisions, which yield a gravity equation for commuting flows. To structurally estimate agglomeration and dispersion forces, we use data on thousands of city blocks in Berlin for 1936, 1986 and 2006 and exogenous variation from the city’s division and reunification. We estimate substantial and highly localized production and residential externalities. We show that the model with the estimated agglomeration parameters can account both qualitatively and quantitatively for the observed changes in city structure. We show ...

July 2005Political Competition and Economic Performance: Theory and Evidence from the United States
with Timothy Besley, Torsten Persson: w11484
One of the most cherished propositions in economics is that market competition by and large raises consumer welfare. But whether political competition has similarly virtuous consequences is far less discussed. This paper formulates a model to explain why political competition may enhance economic performance and uses the United States as a testing ground for the model's implications. It finds statistically robust evidence that political competition has quantitatively important effects on state income growth, state policies, and the quality of Governors.
