The Gini coefficient, Question 1 options: measures income inequality by dividing incomes into bands and calculating the share of income going into each band measures income inequality on a scale of 0 (perfect inequality) to 1 (perfect equality) measures income inequality by dividing incomes into 100 bands and calculating the share of income going into one band with the share going to another measures income inequality on a scale of 0 (perfect equality) to 1 (perfect inequality)

The Gini coefficient is measured by: A. using the formula: the area between the line of perfect equality and the Lorenz curve divided by the area under the line of perfect equality. B. using the formula: the area between perfect inequality and the Lorenz curve divided by the area between the line of perfect equality and the Lorenz curve. C. summing up the total income earned by the population and dividing by the size of the population. D. summing up the cumulative income percentages on the Lorenz curve.

Gini coefficient is a statistic used to measure income inequality within nations. It ranges from 0 to 100, with higher scores indicating more inequality. At the extremes, a Gini score of 0 would mean that everyone in the country earns the exact same income, and a Gini score of 100 would mean that only one person in the country earns all the income. Some people argue that the larger a nation is, the more difficult it is to maintain a fair distribution of incomes. In other words, does income inequality increase as population size increases? You can test this question by conducting a bivariate regression on the data in the table below. Country (1) X: Population (in millions) (2) Y: Gini Score (3) (4) (5) (6) (7) Sweden 8 27 Ethiopia 77 29 Switzerland 11 43 Laos 6 45 UK 59 35 Russia 144 44 US 291 40 Mexico 111 46 Brazil 190 55 What is the covariation of X and Y? Hint: That is what one of the numbers of the total columns is called. Throughout calculating, and for the final answer, round to two decimals.

Exhibit: Gini Coefficients Share of Income A = 2000 A = 1600 Percentage of households A = 600 A = 800 (Exhibit: Gini Coefficients) A simple Lorenz curve for an economy is shown in blue. Various areas of the graph are shaded, and the area of each has been measured and is shown. For this economy, the Gini coefficient would be: a. 0.5 b. 0.2 c. 0.3 d. 0.4
