Understanding Italian Inequality Trends*
构建了一个统一框架，分析1977至2004年间意大利家庭等值收入不平等趋势的驱动因素，发现工作和养老金收入分布变化是主因，妻子劳动参与增加对低收入家庭有拉大不平等的作用。
This article develops a unifying framework for analysing the effects of: (i) the changing distribution of individual incomes by main factor sources, (ii) the increasing participation of wives in the labour force, and (iii) the changing distribution of family types on the distinctive trends towards inequality in equivalent household income in Italy between 1977 and 2004. Changes in the distribution of work and pension incomes explain most of the trend. The higher average likelihood of wage-earning wives had an unequalizing effect on households on the left tail of the income distribution. Little is explained by the changing distribution of family types.
