– Income paid abroad
=$ (437 +50-75) million
= $412 million

c) Net National Product = Gross National Product – Depreciation allowance
=S(412 – 3) million
=$ 409 million

2a(i)X = Demand curve

5 (a) A demand schedule is a table showing the quantities of a commodity demanded at various prices.

b(i) Effective demand refers to the desire for a commodity backed by the ability to pay at a particular price and time.

(ii) Composite demand refers to the demand for a commnodity due to its various uses.

(iii) Derived demand refers to demand for a commodity, not for its own sake, but for the production of another commodity.
ci) In the case where two commodities are substitutes e.g. Margarine and butter.
When the price of margarine increases
from P1 to P2, its quantity demanded
will decrease from Q1 to Q2. When this happens, consumers being rational will switch increasing the demand for butter shown by a rightward shift of the demand curve from D1D1 to D2D2:

C(ii) In the case where the commodities are complement, e.g Torch and batteries

When the price of torch increases from P1 to P2, the quantity demanded will fall from Q1 to Q2. When this happens, the demand for batteries will fall. Shown by a leftward shift of the demand curve from D1 D1 to D2D2.

6a (i) Specific tax is an levied per unit of an output irrespective of its value.

ii. Value added tax is an indirect tax levied on value added to a good or service produced. It is levied on the difference between sales revenue and the cost of producing an output.

b(i) demand is perfectly inelastic if at every price level, quantity demanded remains the same. The market price of the commodity Will rise by the full amount of the tax and the whole burden of the tax rest on the consumer.

OP1 was the price before the imposi tion of an indirect tax and the initial
supply curve was SoSo. When the tax
was imposed, the suppły curve shifted
from SoSo, to S1S1 forcing the price to rise from 0P1 to 0P2. The full amount of the tax is P1E1E2P2, above and is borne by the consumer.

(ii) Demand is perfectly elastic if at a given price, consumers are willing to buy all the commodities that are available and none at any price above the market price.
Since the producer cannot increase the price of the commodity, price remains the same and the entire burden of the tax rests on the producer.

The impositionof an indirect tax results in a leftward shift of the initial
supply curve SoSo to a new supply
curve S1S1. Pice remains the same a
OP1 and the whole burden of the tax
P1E1E2P2 rests on the producer.
