Figure 7. Income persistence in Florence: 1427 vs. 2005
Histograms represent the intergenerational income elasticity obtained as projections of the
pseudo-ICS measure by Güell et al. (2015b); figures for Florence in the 1427 are based on authors’
elaborations on data drawn from 1427 Census of Florence; figures for Florence in the mid-2000s
are drawn from Güell et al. (2015a).
Figure 8. Earnings by professions: 1427 vs. 2000s
1427
2000s
Figures for 1427 are drawn from 1427 Census of Florence; figures for 2005 are drawn from sectoral studies (Studi di settore) by the
Ministry of Economics and Finance for lawyers, doctors, pharmacists and goldsmiths and from Ciapanna et al. (2015) for bankers.
Corresponding average values in the population are reported with diamonds.
