According to the Treaty of Frankfurt (1871) France lost Alsace and Lorraine. In the paper I estimate how a new border affected a growth of towns. Applying difference-in-differences methodology to census data for 1831-1911, I obtain paradoxical result. New border stimulates growth of nearby towns. Observed effect is turned to be persistent and robust to specification changes. Obtained results are contradicted to both theory and other empirical studies (Sturm, Redding (2008), Brülhart et al.(2012) and others).
The purpose of the paper is the systematization of new economic geography research, on the analysis of the agglomeration process in region. Priority of the paper is given to the influence of theoretical research. Scientific novelty of the work is to specify the theoretical and methodological foundations of the agglomeration process due to analyzing the new economic geography attitude. As agglomeration forces facilitating the concentration of economic activity is defined: internal economies of scale, the level of transportation cost, the migration of the mobile labor in response to the wage gap, the elasticity of labor supply, forward and backward linkages of different content and other factors. As important condition is considered the trade costs level between regions. This study suggests that the formation of theoretical models system explaining the agglomeration process is under intense development.
We study Krugman's core–periphery (CP) model for most general cases of nonidentical regions and fully characterize instant and long-run equilibria. Assuming immobility of labor, we describe the behavior of equilibrium wages/real wages. Moreover, the relative wages/real wages of industrial workers can both increase and decrease with the population with which they are associated. Under the assumption of industrial labor mobility, possible patterns of economic evolution, as responses to trade freeness, are fully described. We show that in the case of noticeable agricultural asymmetry, all mobile labor inevitably accumulates in countries with larger agricultural populations.
We study multiregional extension of Krugman's Core-Periphery model. Comprehensive characterization of agglomeration stability
is obtained in terms of the basic parameters of model. In particular, condition of uniqueness of the stable total agglomerated equilibrium were obtained. The main feature of this paper is that the considered model is asymmetric, i.e., uneven allocation of the immobile (agricultural) population across regions is allowed. Unlike the previously known results for asymmetric CP model, which were based on numerical simulations, this research is quite analytical.
