This paper evaluates, in the context of economic geography estimates, the magnitude of the distortions arising from the choice of zoning system, which is also known as the Modifiable Areal Unit Problem (MAUP). We consider three standard economic geography exercises (the analysis of spatial...

Ce travail compare tout d'abord les distributions de salaires et de qualifications de l'Ile-deFrance et du reste du pays. Les salaires sont plus élevés en Ile-de-France de 24%. Ces différences relèvent pour le quart de qualifications plus élevées et pour le reste d'une plus grande...

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...

We evaluate the role that cities play on individual productivity in China. First, we show that location explains a large share of nominal wage disparities. Second, even after controlling for individual and -firms characteristics and instrumenting city characteristics, the estimated elasticity of...

Does productivity increase with density? We revisit the issue usingFrench wage and TFP data. To deal with the ‘endogenous quantity of labour' bias (i.e., urban agglomeration is consequence of high local productivity rather than a cause), we take an instrumental variable approach and introduce...

Using both reduced-form and structural approaches, the spectrum of policy recommendations that can be drawn from empirical economic geography is pretty large. Reduced-form approaches allow the researchers to consider many variables that impact on regional disparities, as long as they are careful...

This paper presents a novel ranking of economics journals. Our methodology is the following. First, we construct an index to rank the 304 journals recorded in the Thomson Reuters (JCR) database, for which citation counts exist. This index combines (sophisticated) citation indexes, field of...

The paper assesses the trade-creating impact of foreign-born residents on the international imports and exports of the French regions where they are settled. The pro-trade effect of immigrants is investigated along two intertwined dimensions: the complexity of traded goods and the quality of...

Measures of urban productivity are typically positively associated with city population. But is this relationship causal? We discuss the main sources of bias in the proper identification of agglomeration effects. We also assess a variety of solutions that have been proposed in the literature to...
