We show that the use of pooled and panel data in estimating convergence across countries (or other territorial areas) may involve some pitfalls since this type of data cannot properly distinguish between actual convergence and the possibility of decreasing growth rates over time within each...

This paper tests for the existence of neoclassical and/or technological catching up between the Italian regions in the last three decades. The tests are performed by means of a modified b-convergence equation and of a model based on the decomposition of output growth. The results imply that...
