Final answer:
The effect of an increase in consumer income on the demand for laptops is a microeconomic issue, thus the answer is 'a) Micro'. A price ceiling does not shift demand or supply but creates a maximum price limit, often resulting in a shortage if set below market equilibrium; therefore, the correct answer is 'd) neither'.
Step-by-step explanation:
The question of whether the effect of an increase in consumer income on demand for laptops is a microeconomic or macroeconomic phenomenon pertains to the field of economics, more specifically to the study of market behavior and consumer choices which is microeconomics. Therefore, the correct answer is Microeconomics (a) Micro. An increase in consumer income generally leads to an increase in demand for normal goods like laptops, as people have more disposable income to spend. This change in demand is typically analyzed within microeconomic models.
Regarding the question about price ceilings, it is important to understand that a price ceiling is a regulation that sets the maximum price that can be charged for a product. A price ceiling does not shift the demand or supply curve; instead, it creates a legally enforced price that can lead to a shortage if set below the market equilibrium. Because it does not shift either curve, the correct answer is d) neither.
