Suppose a government is considering several options to ensure that legal services are provided to the poor:

Option A: All lawyers would be required to devote 5 percent of their work time to the poor, free of charge.

Option B: Lawyers would be required to provide 100 hours of work, free of charge, to the poor.

Option C: Lawyers who earn over $50,000 in a given year would have to donate $5,000 to a fund that the government would use to help the poor.

Discuss the likely effects of each option on the hours of work among lawyers.

(It would help to draw the constraints created by each option.)
