Mark's demand for a doctor visit is given by p=120-q where p is the price per visit in a private medical system and q is the number of doctor visits per year. The marginal cost of each doctor visit is $40.

2.1 If Mark has to pay for health care from his own pocket, what is the efficient quantity of doctor visits he will consume? What is the total cost of his visits?

2.2 In Canada, doctor visits are provided for free to residents (ignoring the tax payment). Now if doctor visits are free, how many doctor visits will Mark take? What is the deadweight loss of this free provision of health care?

2.3 Comparing the outcomes in 2.1) and 2.2), what do we call the behavioural problem associated with Mark in situation 2.2)?

2.4 If the government now requires patients to pay 20% of the cost of doctor visits from their own pockets, how many visits to the doctor will Mark take now? What is Mark's out-of-pocket cost? How much does the government pay for these doctor visits?What is the new deadweight loss?

Draw one diagram and mark all the important numbers in questions 2.1), 2.2) and 2.4) on the same diagram.
