The most commonly used index from the family, ''FGT2'', puts higher weight on the poverty of the poorest individuals, making it a combined measure of poverty and income inequality and a popular choice within development economics. The indices were introduced in a 1984 paper by economists Erik Thorbecke, Joel Greer, and James Foster. The individual indices within the family are derived by substituting different values of the parameter ''α'' into the following equation: $FGT\_\backslash alpha=\backslash frac\; \backslash sum\_^H\; (\backslash frac\; )^\backslash alpha$ where ''z'' is the poverty threshold,'' N'' is the number of people in the economy, ''H'' is the number of poor (those with incomes at or below ''z''), ''yi'' is the income of each individual ''i. ''If $\backslash alpha$ is low then the FGT metric weights all the individuals with incomes below z roughly the same. The higher the value of ''α, ''the greater the weight place on the poorest individuals. The higher the FGT statistic, the more poverty there is in an economy. == FGT0 and FGT1 == With ''α ''= 0, the formula reduces to the headcount ratio: the fraction of the population that lives below the poverty line. $FGT\_0=\backslash frac$ With ''α ''= 1, the formula reduces to the poverty gap index. $FGT\_1=\backslash frac\; \backslash sum\_^H\; (\backslash frac\; )$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Foster–Greer–Thorbecke indices」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
