This Paper first develops a tractable economic geography model we use to investigate the decline of transport costs as a cause of regional inequalities. Next, we perform a structural estimation of this model using a new dataset on road transport costs between the 341 French Employment Areas. We...

This Paper develops a methodology to compute transport costs at low infra-country geographical levels. This simultaneously accounts for the real network infrastructure, a distance cost (fuel, repair, tolls), and a time opportunity cost (wages, insurance and general charges, vehicle use). When...

McCallum (1995) shows in an influential contribution that, even when controlling for the impact of bilateral distance and region size, borders sharply reduce trade volumes between countries. We use in this Paper data on bilateral trade flows between 94 French regions, for 10 industries and two...

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 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...

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...

We consider the literatures on urban systems and New Economic Geography to examine questions concerning agglomeration and how areas respond to shocks to the economic environment. We first propose a diagrammatic framework to compare the two approaches. We then use this framework to study a number...

When firms cluster in the same local labour market, they face a trade-off between the benefits of labour pooling (i.e., access to workers whose knowledge helps reduce costs) and the costs of labour poaching (i.e., loss of some key workers to competition and the indirect effect of a higher wage...

This Paper considers the spatial distribution of economic activities in the European Union. It has three main aims: (i) to describe the data that is available in the EU and give some idea of the rich spatial data sets that are fast becoming available at the national level; (ii) to present...

Firms are more productive on average in larger cities. Two explanations have been offered: agglomeration economies (larger cities promote interactions that increase productivity) and firm selection (larger cities toughen competition allowing only the most productive to survive). To distinguish...
