The table shows three alternative distributions of land ownership in a village with 100 people and 100 hectares of land. Draw the Lorenz curves for each case. For cases I and III calculate the Gini. For case II, show on the Lorenz curve diagram how the Gini coefficient can be calculated. Note this is exercise 5.9 for CORE Project The Economy. Case I 62 people own nothing 38 people own 2.63 hectares each Case II 48 people own nothing 30 people own 1 hectare 22 people own 3.18 hectares each each Case III 100 people own 1 hectare each. (a) What is the Gini for Case I (between 0 and 1, within two decimal places, e.g. 0.12)? Make sure you round correctly. (b) What is the Gini in Case II? (between 0 and 1, within two decimal places, e.g. 0.34)? Make sure you round correctly. (c) What is the Gini in Case III? (between 0 and 1, within two decimal places e.g. .99)? Make sure you round correctly
