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

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.

Market demand
Complementary demand
Competitive 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.
