ERSA Summer school Groningen 2006

Convergence among regions of the enlarged Europe: impact of spatial effects

Nicolas DebarsyCem Ertur


General ideas

General ideas

  • My research topic consists in implementing theoretically spillovers effects in growth models, and thus using spatial econometrics as methodology

  • Many studies over EU 15 NUTS-2 regions but barely one over enlarged EU

  • This study shows importance of spatial effects in EU-25 NUTS-2 regions


General framework

General framework

  • β-convergence framework

    • Absolute (unconditional) convergence

    • Spatial regimes


General framework1

General framework

  • Clubs convergence (allow to take some spatial heterogeneity into account)

  • Use of Getis statistics (local autocorrelation statistics) to define spatial regimes


Description of clubs

Description of clubs


Estimated equation

D1,i=1 if region i belongs to club West

D2,i=1 if region i belongs to club East

Estimated equation


Empirics

Empirics

  • Period: 1993-2002

  • 237 NUTS-2 regions

  • Creation of a weight matrix based on time distance


Estimation of absolute convergence by sar

Estimation of absolute convergence by SAR


Future research and questions

Future research and questions

  • Develop a growth model including spatial effects

  • work on panel data methods applied to spatial econometrics (Matlab routines)

  • How to take outliers effet into account in a frequentist approach?

  • Bayesian econometrics ?
