Theoretical developments and discussions on growth and regional convergence have been accompanied by another debate, associated with the type of data used and quantitative approaches adopted in empirical research. Estimation of convergence equations continues to play a key role in the study of...

Traditionally, the analysis of regional economic convergence is based on the notions of β-convergence and σ-convergence. However, both of these approaches have several drawbacks and limitations. To overcome these difficulties, we apply a more recent non-parametric approach in the convergence...
