In this paper, we investigate the use of interactive effect or linear factor models in regional policy evaluation. We contrast treatment effect estimates obtained by Bai (2009)'s least squares method with the popular difference in difference estimates as well as with estimates obtained using...

There are large spatial disparities in unemployment durations across the 1,300 municipalities in the Ile-de-France region (Paris Greater Area). In order to characterize these imbalances, we estimate a proportional hazard model stratified by municipality on an exhaustive dataset of all...

We develop a model with two asymmetric countries. Firms choose the number and the location of plants that they operate. The production of each firm increases when trade costs fall. The fall also induces multinationals to repatriate their production into a single country, which is likely to be...

Tax competition for a mobile factor is different in 'new economic geography settings' compared to standard tax competition models. The agglomeration rent which accrues to the mobile factor in the core region can be taxed. Moreover, a tax differential between the core and the periphery can be...

This paper aims to test several hypotheses on the determinants of the quality of trade in cross-country regressions, taking a sample of trade competitors in EU markets. The hypotheses are those underlying two models of VIIT: the so-called neo-H-O model based on factor endowment and an "economic...

This paper studies the social desirability of agglomeration and the efficiency arguments for policy intervention in a simple, analytically solvable ‘new economic geography’ model with two trade integrating regions. The location pattern emerging as market equilibrium is “bubbleshaped”,...

Using a French exhaustive dataset, this paper studies the determinants of regional disparities in mortality for patients admitted to hospitals for a heart attack. These disparities are large, with an 80% difference in the propensity to die within 15 days between extreme regions. They may reflect...

This paper presents a simple, analytically solvable Chamberlinian agglomeration model. As in the canonical core-periphery (CP) model, two agglomerative forces are at work. However, the present model exhibits a 'pitchfork bifurcation' rather than the 'tomahawk bifurcation' of the CP model.

An analytically solvable model of new economic geography is developed. Acquisition of skills is costly for workers but it allows them to earn wages that are larger than those of the unskilled. Moreover, skills acquisition can be subsidized by a regional government. For large transport costs,...
