Sectoral border effects and the geographic concentration of production

Abstract

The object of this paper is to study the relationship between the border effect and the geographic concentration of production. We explain this relationship through the home market effect and test the robustness of this explanation by using an analysis that considers the European single market. A sectoral gravity equation is estimated with different econometric estimators; in particular, we discuss a recently suggested estimator for log-linear CES models. Overall, our findings suggest a steady relationship between the border effect and the concentration of production. Furthermore, the analysis of concentration through a synthetic index provides us with valuable insights into the structure of the European industry.

“…However, as discussed by Santos‐Silva and Tenreyro (), the OLS estimation of the log‐linear form may lead to biased results in case of heteroscedasticity. Thus, Santos‐Silva and Tenreyro () suggest a Poisson‐based estimator; for a comparison of different estimators, see Cafiso (). More recently, Burger et al () have argued that the solution proposed by Santos‐Silva and Tenreyro () is vulnerable to over‐dispersion and/or to excess of zero observations in the dependent variable.…”

Sectoral Trade Freeness and Agglomeration in the EU: An Empirical Test Strategy

“…The distribution of production is uneven throughout the geographic space. Agglomeration emerges because of di¤erent causes and, usually, it can be explained through direct and evident arguments such as infrastructure availability, manufacture tradition, resource endowments, etc; for a discussion about this in the case of the EU, see Ca…so (2011). By abstracting from speci…c cases, New Economic Geography models (Baldwin et al 2005) provide a formalization of these processes and stress the role of trade costs.…”
