Spatial disparities in mortality can result from spatial differences in patient characteristics, treatments, hospital characteristics, and local healthcare market structure. To distinguish between these explanatory factors, we estimate a fexible duration model on stays in hospital for a heart...

Spatial wage disparities can result from spatial differences in the skill composition of the workforce, in non-human endowments, and in local interactions. To distinguish between these explanations, we estimate a model of wage determination across local labour markets using a very large panel of...

We study the impact of local taxation on the location and growth of firms. Our empirical methodology pairs establishments across jurisdictional boundaries to estimate the impact of taxation. Our approach improves on existing work as it corrects for unobserved establishment heterogeneity, for...

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...

This paper is a statistical evaluation of the 1997 enterprise zone program in France. We investigate whether the program increased the pace at which unemployed workers residing in targeted municipalities and surrounding areas find employment. The work relies on a two-stage analysis of...

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...

Does productivity increase with density? We revisit the issue using French 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...

Mortality differences between university, non-teaching public and for-profit hospitals are investigated using a French exhaustive administrative dataset on patients admitted for heart attack. Our results show that innovative procedures play a key role in explaining the effect of ownership status...

We propose an integrated framework to discuss the empirical literature on the local determinants of agglomeration effects. We start by presenting the theoretical mechanisms that ground individual and aggregate empirical specifications. We gradually introduce static effects, dynamic effects, and...

This paper investigates spatial variations in product prices using an exhaustive micro dataset on fish transactions. The data record all transactions between vessels and wholesalers that occur on local fish markets in France during the year 2007. Spatial disparities in fish prices are sizable,...
