3 . In the land of Chin there are two distinct and equally numerous peoples: Yins and Yans. The Yang have historically been stronger and more aggressive that the Yins. Both the Yins and Yans play paddle tennis, but paddle tennis tournaments have always been segregated by group because of the physical advantages of the Yans. The Yin do not object to paddle tennis tournaments being segregated, but recently have been upset about the fact that the top Yin players receive less than the top Yan players. You have been hired by the Chin Paddle Tennis Association (CPTA) to access the market for paddle tennis players. CPTA have asked you a few questions given below.

  • What is the most likely source of the wage differential between the Yin and Yan paddle tennis players?

7.  (based on Slate article) Suppose you’re the manager of a corporation that employs one black and nine whites, paying the black $60,000 and the whites $100,000 apiece. On top of wages to workers, you pay shareholders dividends in the amount of one-half of the total wage payout amount. You notice that you could increase the value of your company by firing your nine $100,000 white employees and replacing them with $60,000 blacks. So next year you do exactly that. The shareholders still receive on-half of the wage payout plus any difference between this year and last year payouts. Calculate the company’s total wage payouts and payments to shareholders last year and this year. How much better off are your shareholders in the year when you don’t practice discrimination compared to the year when you do?
