Which of the following best represents a macroeconomic topic rather than a microeconomic one?

To distinguish between macroeconomic and microeconomic topics:

• Microeconomics deals with individual economic units, such as households, firms, and specific markets.
• Macroeconomics deals with the economy as a whole, including aggregate phenomena like inflation, unemployment, economic growth, and government policies that affect the entire economy.

Let's analyze each option:

• A. A farmer deciding how much maize to plant based on expected market prices. This is a decision made by an individual producer (a farmer) in a specific market (maize). This is a microeconomic topic.
• B. A cell phone manufacturer adjusting production after a competitor cuts its prices. This involves the behavior of a single firm (a cell phone manufacturer) in response to competition in a particular industry. This is a microeconomic topic.
• C. The South African Reserve Bank increasing interest rates to reduce inflation. The South African Reserve Bank is a central bank, and its decision to change interest rates is a monetary policy action aimed at influencing the overall economy to control inflation, which is an economy-wide phenomenon. This is a macroeconomic topic.
• D. A supermarket determining how to price bread to maximize profit. This is a pricing decision made by an individual firm (a supermarket) for a specific product (bread). This is a microeconomic topic.

The correct option is C.
C. The South African Reserve Bank increasing interest rates to reduce inflation.
