The Costs of Agglomeration: Land Prices in French Cities

Combes, Pierre-Philippe; Duranton, Gilles; Gobillon, Laurent - C.E.P.R. Discussion Papers - 2012

We develop a new methodology to estimate the elasticity of urban costs with respect to city population using French land price data. Our preferred estimate, which handles a number of estimation concerns, stands at 0.041. Our approach also yields a number of intermediate outputs of independent...

The productivity advantages of large cities: Distinguishing agglomeration from firm selection

Combes, Pierre-Philippe; Duranton, Gilles; Gobillon, Laurent - C.E.P.R. Discussion Papers - 2009

Firms are more productive on average in larger cities. Two explanations have been offered: agglomeration economies … selection model and a standard model of agglomeration. Stronger selection in larger cities left-truncates the productivity … distribution whereas stronger agglomeration right-shifts and dilates the distribution. We assess the relative importance of …

Rational expectations in urban economics

Berliant, Marcus; Yu, Chia-Ming - In: Regional Science and Urban Economics 43 (2013) 2, pp. 197-208

Canonical analysis of the classical general equilibrium model demonstrates the existence of an open and dense subset of standard economies that possess fully-revealing rational expectations equilibria. This paper shows that the analogous result is not true in urban economies under appropriate...

Labour Specialization and City Formation

Berliant, Marcus; Zenou, Yves - C.E.P.R. Discussion Papers - 1995

This paper explores the formation of cities through labour specialization, gains to trade, a fixed cost for the transportation network, imperfect competition between firms, and the commuting costs of consumers. The model uses a very general setting, allowing a multidimensional location space and...

The mechanisms of spatial mismatch

Gobillon, Laurent; Selod, Harris; Zenou, Yves - C.E.P.R. Discussion Papers - 2005

The Spatial Mismatch Hypothesis (SMH) argues that low-skilled minorities residing in U.S. inner cities experience poor labour-market outcomes because they are disconnected from suburban job opportunities. This assumption gave rise to an abundant empirical literature, which confirmed this...

Labor Differentiation and Agglomeration in General Equilibrium

Berliant, Marcus; Zenou, Yves - C.E.P.R. Discussion Papers - 2012

The aim of this paper is to explore the structure of cities as a function of labor differentiation, gains to trade, a fixed cost for constructing the transportation network, a variable cost of commodity transport, and the commuting costs of consumers. Firms use different types of labor to...

The Effect of Segregation and Spatial Mismatch on Unemployment: Evidence from France

Gobillon, Laurent; Selod, Harris - C.E.P.R. Discussion Papers - 2007

In this paper, we investigate how residential segregation and bad physical access to jobs contribute to urban unemployment in the Paris region. We first survey the general mechanisms according to which residential segregation and spatial mismatch can have adverse labour-market outcomes. We then...

Spatial Mismatch: From the Hypothesis to the Theories

Gobillon, Laurent; Selod, Harris; Zenou, Yves - C.E.P.R. Discussion Papers - 2003

Since the 1950s, there has been a steady decentralization of entry-level jobs towards the suburbs of American cities, while racial minorities — and particularly blacks — have remained in city centres. In this context, the spatial mismatch hypothesis argues that because the residential...

Sorting and local wage and skill distributions in France

Combes, Pierre-Philippe; Duranton, Gilles; Gobillon, Laurent - In: Regional Science and Urban Economics 42 (2012) 6, pp. 913-930

This paper provides descriptive evidence about the distribution of wages and skills in denser and less dense employment areas in France. We confirm that on average, workers in denser areas are more skilled. There is also strong over-representation of workers with particularly high and low skills...

The Identification of Agglomeration Economies

Combes, Pierre-Philippe; Duranton, Gilles; Gobillon, Laurent - C.E.P.R. Discussion Papers - 2010

causal? We discuss the main sources of bias in the proper identification of agglomeration effects. We also assess a variety …
