Exercise 2. The income distribution for the rich part of the world Table 2.4 shows GOP per worker {in 1996 US dollars) and population size for 1960 and 2000 for the rich part of the world (defined here as the OECD countries for which data were available).

Construct Lorenz curves for the rich world for 1960 and 2000, respectively, assuming that everybody in the population earned the GOP per worker of the relevant year, and draw the two curves in one figure. Compute the Gini coefficient for each year. Comment on how inequality, or equality, among the rich has developed. Compare this to how the income distribution of the world has developed. Relate this to what you know about convergence from Section 3.
