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...

A prominent feature of economic geography in America is the positive correlation amongst local incomes, housing costs and city population. This paper embeds a “black box” agglomeration economy within a more neoclassical general equilibrium model of local wages, rents and population to assess...

We estimate how trade openness affects the relationship between wages, labour productivity and foreign wages using sector-level time series for several EU member states. In some countries wages became less responsive to foreign wages as trade costs declined. We show this counter-intuitive result...

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...

Urbanization economies – the effects on productivity and utility created endogenously by larger cities – are a fundamental component of both the economic geography of modern societies and the perpetuation of innovation and economic growth at a national level. Cities account for vast...

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...
