The consumption function of an economy with no government
sector and no foreign trade is C = W120 + 0.6Y. (C = aggregate consumption and
Y national income).
If investment expenditure is autonomous and equal to W 280,
what is the equilibrium level of INCOME ?
Correct Answer
D. N1000
Explanation
The equilibrium level of income is determined by the point where aggregate consumption (C) equals national income (Y). In this case, the consumption function is C = W120 + 0.6Y and investment expenditure is autonomous and equal to W280. To find the equilibrium level of income, we need to set C equal to Y and solve for Y.
C = Y
W120 + 0.6Y = Y
W120 = 0.4Y
Y = W120 / 0.4
Y = W300
Therefore, the equilibrium level of income is N1000.

The winner of a T.V quiz is offered a choice of either N1000
or the content of one or other of two
sealed boxes. She’s told that one box contains N2500 and that the other box is
empty. What is the opportunity cost to the individual of opting for the N1000
price.
Correct Answer
A. A 50% chance of winning W2500
Explanation
The opportunity cost of opting for the N1000 prize is the potential benefit that is foregone by not choosing the other option. In this case, the other option is a 50% chance of winning W2500. Therefore, the opportunity cost is the possibility of winning W2500 instead of the guaranteed N1000.

Which schedule show the maximum price at which a firm would
able to sell any given level of output.
Correct Answer
D. Supply schedule
Explanation
The supply schedule shows the maximum price at which a firm would be able to sell any given level of output. This is because the supply schedule represents the quantity of goods or services that a firm is willing and able to produce and sell at different prices. As the price increases, the firm is willing to supply more output, up to a certain point where the maximum price is reached. Therefore, the supply schedule is the correct answer as it directly relates to the maximum price a firm can sell its output.

In which circumstance will an indirect tax fall entirely upon
the producer of a commodity?
Correct Answer
B. When the elasticity of demand is unit at all points on demand curve
Explanation
When the elasticity of demand is unit at all points on the demand curve, it means that the percentage change in quantity demanded is equal to the percentage change in price. In this case, the burden of the tax will fall entirely upon the producer of the commodity because they will not be able to pass on any of the tax to the consumers through higher prices. The producer will have to bear the full cost of the tax, which will reduce their profits.

In a closed economy with no government , the value of the
investment multiplier is 3 by how much will consumption increase, if investment
increase by N3000 ?
Correct Answer
C. W600
Explanation
The investment multiplier measures the change in GDP that occurs as a result of a change in investment. In this case, the investment multiplier is 3, which means that for every increase in investment of N3000, GDP will increase by 3 times that amount, or N9000. Since consumption is a component of GDP, it will also increase by the same amount, N9000. Therefore, if investment increases by N3000, consumption will increase by N9000. The answer option that represents this increase in consumption is W600.

An employer currently employs 200 workers. The marginal cost
of hiring an addictional worker is N502. If the employees current wage bill is
N20,000 by how much will the wage paid per worker need to be increased in order
to attract one more worker ?
Correct Answer
C. N2.52
Explanation
The marginal cost of hiring an additional worker is N502. This means that the employer will have to pay an additional N502 in wages for each new worker hired. The employer wants to attract one more worker, so they will need to increase the wage paid per worker by N502. Therefore, the wage paid per worker will need to be increased by N2.52 in order to attract one more worker.

Given the cost function C = 160 + 36q, What is the average
cost of 20 units of output?
Correct Answer
C. N880
Explanation
The average cost of 20 units of output can be calculated by dividing the total cost by the number of units. In this case, the cost function is given as C = 160 + 36q, where q represents the number of units. Plugging in q = 20, we get C = 160 + 36(20) = 880. Therefore, the average cost of 20 units of output is N880.

When the important of a commodity is limited to a definite
quantity, the control means used is known as
Correct Answer
A. Quotas
Explanation
Quotas are a control means used when the importance of a commodity is limited to a definite quantity. Quotas restrict the quantity of a particular commodity that can be imported or exported, usually to protect domestic industries or manage trade imbalances. This control mechanism helps regulate the supply and demand of the commodity and can have an impact on its price and availability in the market.
