the lower partial mean consumption expenditures and the horizontal axis reports the cumulative population share. A generalized Lorenz growth curve graphs the growth of lower partial mean per capita consumption expenditure for each population percentile. Thus, a generalized Lorenz growth curve indicates how every lower partial mean is changing over time.
General Mean Growth Curve Figure A.5 graphs the general mean growth curve for Georgia’s per capita expenditure. The vertical axis reports the annual growth rate of the general mean consumption expenditures and the horizontal axis reports parameter α, also known as a society’s degree of aversion toward inequality. A general mean growth curve graphs the growth of different general means and thus indicates how the general means are changing over time. The growth rate in mean per capita expenditure is the same as the growth rate of general mean at α = 1.
