PART B: TRUE/FALSE WHY QUESTIONS

1. [6 marks] The criterion of “portability” under the Canada Health Act refers to the fact that the provincial health insurance plan must cover non-residents who are      visiting the province.

True False Why?

False. The criterion of “portability” refers to the fact that the provincial health insurance plan must cover provincial residents, even when they are out-of-province. There is no principle that non-residents should be covered by a provincial health insurance plan.


2. [6 marks] An efficiently cost-effective allocation of productive resources must also be technologically efficient.

True False Why?

True. The definition of a cost-effective allocation is one that achieves the lowest-cost technically efficient allocation with no wasted resources. All cost-effective allocations

are required to be technically efficient and on the PPF to be relevant otherwise one could lower costs by moving to a irrelevant technologically inefficient point inside the

PPF.


3. [6 marks] A new cough medicine appears on the market with the same properties and effectiveness as the existing cough medicine only the new medicine is offered at a          lower price. We would expect the demand curve for the existing medicine to shift to         the left because the two goods involved are complements.

True False Why?

False. It is true that we would expect the demand for the existing medicine to shift left because some people would change from purchasing the existing medicine to purchasing the new cough medicine. This would cause demand to be lower for the existing medicine. However this shift to the left is caused because the two medicines are substitutes (they provide the same service/use to consumers) not because they are complements (they are not consumed together).


4. [6 marks] More education is correlated with better health because people with “long time horizons” with preferences for the future tend to invest in both. Therefore we        should increase subsidies to education in order to increase health.

True False Why?


False. If the two are correlated then one does not necessarily cause the other, so increasing education may not cause an increase in health. The conclusion could be to induce people to consider longer time horizons (increase their preference for the future) instead of subsidizing their education. Education subsidies would be expected to increase health if the affect was causal, like the theory that educated people produce health more efficiently.


PART C: SHORT ANSWERS

5. Consider the demand equation for good X estimated by linear regression,                 Qx=1000 - 3.3Px + 0.2Pz + 0.001Y, where Qx is quantity demanded, Px is the price of the good in question, Pz is the price of another good Z and Y is income. Assume that   the t statistics for Px, Pz and Y are 2.8, 3.9 and 0.04 respectively.

a) [5 marks] Is good Z a complement or a substitute?

The coefficient in front of the price ofZ is a positive number (+0.2) so this indicates that as the price ofZ increases, the quantity demanded ofX also increases. This is true for a substitute since the person switches to X when Z becomes more expensive. Since the t

statistic for Pz is greater than 1.96 we know that the regression shows a significant relationship.


b) [5 marks] Can we confidently say whether demand for good X increases as Income (Y) increases?

The coefficient in front of income is a positive number (0.001) which would indicate a normal good since quantity demanded would increase ifincome increased, but the t- statistic

for Y is less than 1.96 indicating that this is not a significant relationship. Therefore we cannot confidently say demand for goodXincreases when Yincreases, we would have to

conclude there is no significant relationship between income and demand.


6. [6 marks] What is the difference between viewing health as a consumption good and viewing it as an investment good?

Having preferences for health as an investment good is due to health providing healthy days with which one can work (earn a wage/salary) and have leisure time. Having preferences for health as a consumption good means that health gives you direct utility all by itself (ex. you feel happier when you are healthier).
