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...

This paper uses a unique database that provides value-added, employment, and population levels for the entire set of French departments for the years 1860, 1930, and 2000. These data cover three sectors: agriculture, manufacturing, and services. This allows us to study the evolution of spatial...

This paper provides a method to single out customer-based discrimination in the housing market. We build a matching model with ethnic externalities where landlords differ in the number of housing units they own within the same building. Multiple-dwelling landlords discriminate more often than...

The paper investigates the link between the over-exposure of African immigrants to unemployment in France and their under-representation in jobs in contact with customers. We build a two-sector matching model with ethnic sector-specific preferences, economy-wide employer discrimination, and...

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...
