The demand and supply curves of physician service is given by the equations -- Demand curve: Q_d= 500 – 3.0 P and Supply curve: Q_s = -100 + 1.8 P in absence of insurance. If insurance is introduced with 40% coinsurance, market price and quantity after the introduction of insurance would be

		Price=$200 and Q=260
		Price=$125 and Q=125
		Price=$200 and Q=0

Expert Solution

We have demand function Q_d= 500 – 3.0 P and Supply function: Q_s = -100 + 1.8 P

With 40% coinsurance, the price is reduced by 40% so we have Qd = 500 - 3 * 0.4P = 500 - 1.2P

New price is given by

500 - 1.2P = -100 + 1.8P

600 = 3P

P = 200

Q = 500 - 1.2*200 = 260 units

Select Price=$200 and Q=260

Demand and supply curves of physician care services per day are given by the following equations:...

Demand and supply curves of physician care services per day are given by the following equations: Demand curve: Qd= 700 – 3 P Supply curve: Qs= -260 + 5 P where Q is the number of visits in a day and P is the fee per consultation. Introduce insurance with one-third coinsurance. The insurance is provided free of charge (no premium). What will be the impact of introducing the insurance on quantity, consultation fee and health care expenditure per day? Compare these...
