Industries are sometimes located in areas which are not profitable so as to
Encourage rural-urban migration
Be able to even-out development
Bring about external economies of scale
Be able to reap internal economies of scale
Correct answer is B
Industries are sometimes located in areas which are not profitable so as to even-out development. This is a government policy that aims to reduce regional disparities in economic development.
By locating industries in less developed areas, the government hopes to create jobs and boost economic growth in these areas. This can help to reduce poverty and improve the standard of living in these areas.
The supply of light could be met using a candle, lantern and gas lamp. This is an example of a
Complementary supply
Abnormal supply
Joint supply
Composite supply
Correct answer is A
The supply of light could be met using a candle, lantern, and gas lamp is an example of joint supply. This is because the three products are produced together and cannot be produced separately.
In joint supply, two or more products are produced from the same input. The products are said to be jointly supplied because they are produced simultaneously and cannot be produced separately.
For example, in the case of the supply of light, the three products are candles, lanterns, and gas lamps. These products are produced from the same input, which is fuel. The products cannot be produced separately because they all require fuel to be produced.
A monopolist may enjoy abnormal profit only if its
Marginal cost exceeds marginal revenue
Demand curve is perfectly elastic
Expenditure on advertisement increases
Price exceeds average total cost
Correct answer is D
A monopolist may enjoy abnormal profit only if its price exceeds average total cost. This is because a monopolist is the only producer in the market, and they can therefore set the price of their product. If the price exceeds average total cost, the monopolist will be making a profit.
If the government stops subsidy on cocoa production, the supply curve of cocoa will
Become vertical
Remain unchanged
Shift to the left
Shift to the right
Correct answer is C
If the government stops subsidy on cocoa production, the supply curve of cocoa will shift to the left. This is because the subsidy was making it cheaper to produce cocoa, so when the subsidy is removed, the cost of production will increase. As a result, fewer cocoa beans will be supplied at any given price.
The demand for a factor input as a result of the demand for its output is known as
Market demand
Complementary demand
Competitive demand
Derived demand
Correct answer is D
The demand for a factor input as a result of the demand for its output is known as derived demand. This is because the demand for the factor input is derived from the demand for the final product that the factor input is used to produce.
For example, the demand for labor is derived from the demand for goods and services that are produced by labor. If the demand for goods and services increases, then the demand for labor will also increase.
