Can it be illustrated graphically? b. Consider a 12-person economy where the individuals are employed equally across the sectors. If the modern urban wage = £8, the informal urban wage = £3, and the tradition rural income = £1, what is the squared poverty gap index (P2) given that the poverty line = £1.25? Suppose that rural income now rises to £2, other things being equal, how would you characterise and show this type of growth?

Why has the distribution of income become more unequal in the last 30 years
Use the data from the table below to construct a Lorenz curve. Income Shares in the United States Lowest 20% Second Lowest 20% Third 20% Fourth 20% Highest 20% 5.2 10.3 15.3 22.4 46.9
Consider an economy with 4000 people and the following income distribution: each person in the bottom quartile of the income distribution earns $10 dollars per hour; each person in the 2nd quartiles earns $20 dollars per hour; each person in the 3rd quartiles earns $25 dollars per hour;and each person in the top quartile of the income distribution earns $45 dollars per hour. (2) Suppose the bottom quartile pays no taxes, the 2nd quartiles pay 10% its income in taxes, the 3rd pays 20% and the top quartile pays 40% of its income in taxes. 80% of all tax money is redistributed equally to all citizens in the form of military defense, government pensions (social security), roads/highways, etc. The remaining tax money is distributed entirely to the poorest quartile. What is the Gini coefficient associated with this redistribution plan?
Q2] Given is the data for Country A and B: Population Fraction Country A's Income Country B's Income bottom 25% 5 million 10 million 2nd 25% 10 million 15 million 3rd 25% 30 million 20 million top 25% 55 million 55 million a) Compute the cumulative income share and neatly plot (using Excel) the Lorenz curve for these two countries with labels. Feel free to use excel template that I have uploaded and copy paste the plot. b) Compute the Gini coefficient assuming the region beneath the two respective Lorenz curve is For country A = 0.2875 For country B = 0.3250
2. Constructing a Lorenz curve from income shares data The following table shows the approximate income distribution for Peru, Bulgaria, and Lithuania in 2016. In particular, it shows the income shares of each fifth of the income distribution. Percentage Share, 2016 Percentage of Families Peru Bulgaria Lithuania Lowest fifth 4 9 7 Second-lowest fifth 8 14 12 Middle fifth 12 17 16 Second-highest fifth Highest fifth 20 22 22 56 38 43 has the most total income. On the following graph, plot the Lorenz curves for the three countries. Plot Peru's Lorenz curve using the green points (triangle symbol), Bulgaria's Lorenz curve using the blue points (circle symbol), and Lithuania's Lorenz curve using the purple points (diamond symbol). Be sure to plot the first point of each Lorenz curve at (0,0). Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.
