The following data were published by UN University for Finland. Total Annual Household Income by Income Class in 2017 U.S. Dollars (thousands). Income Class 0 - 10 10 - 15 15 - 20 20 - 30 30-45 45 - 60 60 - 75 75+ % of 3.5 11.0 19.1 36.7 21.4 5.3 1.6 1.3 Households These were fitted with a Singh-Maddala Model which yielded the following results: Finland 2017 Singh-Maddala Model Mean = $26.809 (thousands) Population = 100% A1 = 5.724916E-06 A2 = 3.80159 A3 = 1.002997 19.1 chi-sqrd = 0.003 K - S = 0.002 36.7 11 21.4 5.3 3.5 1.6 10 20 30 40 50 60 70 80 Income US Dollars (thousands)a. The decile income shares are given as: Decile 1 2 3 4 5 6 7 8 9 10 Share 3.91 5.63 6.68 7.58 8.46 9.41 10.5 11.93 14.16 21.4 Find the incomes which separate the above deciles and insert them below. 13.415 16.604 19.132 21.488 23.905 26.592 29.865 34.406 42.569 b. Compute the average income for deciles 1,2,8,9 and 10 and insert them in the table below. Hint: Total Income = Mean income X 100. Decile population = 10. Decile 1 2 8 9 10 Average 10.482 15.093 31.983 37.962 57.371 income c. Suppose it is politically decided to raise the average income of all deciles above 15.0. Which decile(s) would have to get an increase in total decile income? Ans. = decile 1 d. If it is decided to tax the 10" decile the amount needed for re-distribution to the deciles needing more total income, how much should the 10th decile be taxed?. Ans. = 45.177 e. Find the average household income of the 10th decile after redistribution. Ans. = 52.854
