Suppose that MRPL = 20 - 0.5L for lefthanded workers, where L = the number of left-handed workers and MRPL is measured in dollars per hour. The going wage for left-handed workers is $10 per hour, but employer A discriminates against these workers and has a discrimination coefficient, D, of $2 per hour. Graph the MRPL curve and show how many lefthanded workers employer A hires. How much profit has employer A lost by discriminating?
