Abstract

This paper provides a survey of the non parametric approaches applied to income distribution analysis, focusing on kernel method and, in particular, on the choice of the bandwidth. To account for sample design and data sparseness, weighted kernel density with an adaptive bandwidth is suggested. Moreover, the assessment of Significant of ZERo crossings of derivatives helps determine which features in the family of empirical distributions are statistically significant for given bandwidths. The SiZer approach has been modified for adaptive kernel estimation procedures. Empirical evidence for household income distribution in Italy over the period 1989-2002 is emphasized.
