uppose that an economy this year consists of 25 families with incomes of $10,000, 25 families with incomes of $20,000 and 25 families with incomes of $100,000. Suppose that the poverty line for families is $25,000 and this does not change. Next year, suppose that incomes double for all families in the economy: 25 families now have incomes of $20,000, 25 families now have incomes of $40,000, and 25 families now have incomes of $200,000. As a result of this change, A. the poverty rate and the Gini coefficient have remained constant. B. the poverty rate has decreased and the Gini coefficient has increased. C. the poverty rate has decreased and the Gini coefficient has remained constant. D. the poverty rate has decreased and the Gini coefficient has decreased.
