3. The Gini Index Problem How is possible to measure the distribution of income among the inhabitants of a given country One such measure is the Gini index, named after the Italian economist Corrado Gini, who first devised it in 1912. We first rank all households in a country by income and then we compute the percentage of households whose income is at most a given percentage of the country's total income. We define a Lorenz Curve y L(x) on...
Lorenz Curve The United Nations reports data on income distribution for different countries as a ratio of the income of the richest 10% to the income of the poorest 10%. If the ratio for Japan is 4.5 and the ratio for the United States is 15.9, which of the following statements is correct? a) This ratio is the slope of the Lorenz curve for each country. b) This is the same thing as the Gini coefficient. c) The distribution of...
1) Figure 2 below is an image of a Lorenz curve. a. When the Lorenz curve sags lower, does that mean the economy is more equal or more unequal? b. Explain how to use the information in Figure 2 to calculate the Gini coefficient. i. What is the typical range for Gini coefficients? ii. What does a high number indicate? 2) (10) Describe the inequality in income and wealth between countries, and explain whether each has grown or shrank over the past 50 years. Why...

PART A In the United States, the gap between the higher-income groups and the lower-income groups, as a percentage of what they earn relative to the country's total earnings, has widened the past several decades. Therefore, we can conclude that: The relative gap between the richest 20% of our income earners and the poorest 20% of our income earners has narrowed. the richest 20% of our income earners has gotten poorer and the poorest 20% of our income earners has...
3. In the real world, we do not usually have nice formulas for the Lorenz Function. Instead, we have a bunch of data points. The following table describes the wealth distribution in the United States in 2016.1 0 0.20.4 0.6 0.8 0.9 0.95 0.99 1 L(p) || 0 -0.008 -0.005 0.019 | 0.101 0.212 0.333 | 0.604 (a) Using the table above, determine what percentage of the wealth in the United States was owned by the richest 1% of the...
