This paper compares different conditional density stimators to analyze the cross-sectional distribution dynamics of regional per-capita incomes in Europe during the period 1980-2002. First, a kernel estimator with fixed bandwidth (the method traditionally applied in the literature on intra-distribution dynamics) gives evidence of convergence. With a modified estimator with variable bandwidth and mean-bias correction, the dominant income dynamics is that of persistence and lack of cohesion: only a fraction of very poor regions improves its position over time converging towards a low relative income (“poverty trap”). An alternative graphical technique (more informative than the traditional contour plot) is also proposed to visualize conditional densities. Finally, a first-order spatial autoregressive model is applied to estimate the effect of spatial dependence on the evolution of income distribution.

Abstract

This paper compares different conditional density stimators to analyze the cross-sectional distribution dynamics of regional per-capita incomes in Europe during the period 1980-2002. First, a kernel estimator with fixed bandwidth (the method traditionally applied in the literature on intra-distribution dynamics) gives evidence of convergence. With a modified estimator with variable bandwidth and mean-bias correction, the dominant income dynamics is that of persistence and lack of cohesion: only a fraction of very poor regions improves its position over time converging towards a low relative income (“poverty trap”). An alternative graphical technique (more informative than the traditional contour plot) is also proposed to visualize conditional densities. Finally, a first-order spatial autoregressive model is applied to estimate the effect of spatial dependence on the evolution of income distribution.
