1. a. The demand for skilled workers has risen relative to less-skilled workers, which has increased inequality. How would you show this through a Lorenz Curve or Gini Coefficient that income inequality is increasing in the U.S. over time (Hint: Graph the Lorenz Curve over time and explain it and its relationship to the Gini Coefficient).

b. Second officials at the Department of Labor are concerned that new technologies in the U.S. are impacting workers. Explain how policy makers who are concerned with technological change (use of robots, artificial intelligence, gig economy) would develop programs to reduce income inequality and show how it influences wages and incomes of workers.
