The arc price elasticity of
(a)
Explanation of Solution
The arc price elasticity of demand can be calculated using the following equation:
The calculated value shows that the arc price elasticity of demand for healthcare of consumers in Japan is 0.27.
Price elasticity of demand: Price elasticity of demand refers to the degree of responsiveness of demand for a commodity after a change in its price.
(b)
The effect of a higher income in Tokyo than Hokkaido on arc price elasticity of demand.
(b)
Explanation of Solution
Incomes are generally higher in Tokyo. This means that demand must also be higher in Tokyo. At an income level equivalent to that in Hokkaido, the quantity demand would be lower in Tokyo. That is, keeping income constant at the income level of Hokkaido, the number of outpatient visits would be lower than 1.25 at the price of 20. This means an increase in price from 10 to 20 would cause a greater decrease in the number of outpatient visits than shown in the given data. Therefore, the answer to the past question is an underestimation of price elasticity.
(c)
The effect of change in price per visit on the demand for health care.
(c)
Explanation of Solution
Elasticity of demand of Tokyo can be calculated as follows:
The calculated value shows that the change in quantity demand for healthcare in Tokyo is -0.135. Therefore, an increase in price would reduce the demand for health care.
Elasticity of demand of Hokkaido can be calculated as follows:
The calculated value shows that the change in quantity demand for healthcare in Hokkaido is -0.135. Therefore, a fall in price would reduce the demand for health care in Hokkaido.
(d)
Price elasticity of demand for healthcare in Japan.
(d)
Explanation of Solution
(e)
Calculate the elasticity of demand for healthcare for Tokyo and Hokkaido separately.
(e)
Explanation of Solution
Elasticity of demand for Tokyo can be calculated as follows.
The calculated value shows that the elasticity of demand for Tokyo is 2.18.
The elasticity of demand for Hokkaido can be calculated as follows:
The calculated value shows that the elasticity of demand for Hokkaido is 0.55.
(f)
The effect of an increase in price on the demand for healthcare.
(f)
Explanation of Solution
Elasticity of demand for Tokyo can be calculated as follows:
The calculated value shows that the demand for healthcare is 0.81 percentage.
(g)
The combined elasticity of demand for Tokyo and Hokkaido.
(g)
Explanation of Solution
The calculated value shows that the combined elasticity of demand would be 0.556.

- Suppose that there are two countries, Beta and Gamma. Suppose further that everyone in country Beta is on Insurance B and everyone in country Gamma is on Insurance G. Suppose further that both governments use government-set price controls. In 2005, country Beta decided to change the reimbursement rate for pharmaceuticals, but country Gamma did not make this change. You, a researcher, want to study the effect of offering coverage for this drug had an impact on health expenditures. You have average health expenditures for State Beta and Gamma prior to 2005 and post-2005. Using your finding from the question above, you can infer that country Beta likely _____ reimbursement rates for pharmaceutical drugs.
