The paper extends the methodological toolbox of measures of industrial concentration and regional specialization. First, a taxonomy is proposed which gives rise to a modular construction system for disproportionality measures based on three characteristic features: the projection function, the...

This paper establishes eight stylized facts on the evolution of the localization of economic activity across industries and regions in the EU-15 since 1980. Localization, which nests concentration and specialization, is measured by a Theil index. The stylized facts reveal a broad aggregate trend...

We analyze the concentration of FDI in India at the district level, based on project-specific location choices since the reform program in the early 1990s. The decomposition property of the Theil index allows us to trace changes over time in the overall concentration of FDI to changes in...

Night lights could be a valuable proxy of economic activity at the subnational level when GDP data are lacking or of poor quality. Supplementing Henderson et al.’s (2012) analysis at the national level, we assess the stability of the elasticity of GDP with regard to night lights across regions...

This paper solves one of the puzzles in the analysis of regional and industrial distributions of economic activity, the discrepancy between absolute and relative measures. It shows that the difference between an absolute and a relative Theil index of localization can be expressed in terms of...

By tracking the changes in different margins of Theil indices during the period 1995-2015, we re-consider the question of whether bilateral and multilateral donors have targeted aid increasingly to particularly needy recipient countries with relatively good governance in order to improve the...
