A lecturer demonstrates to his students some principles of Economics. He pays attention to the science, which tries to find answers to the following question: What causes unemployment? What causes inflation? What creates or stimulates economic growth? One of the students thinks that the mentioned science examines economy-wide phenomena such as price levels, rate of economic growth, national income, gross domestic product (GDP), and so on. What branch of economics are they talking about?

In this scenario, the lecturer and student are discussing the branch of economics known as macroeconomics. Let me explain why this is the correct branch:

1. Definition of Macroeconomics: Macroeconomics is the branch of economics that studies the behavior and performance of an economy as a whole. It focuses on economy-wide phenomena rather than individual markets.
2. Key Areas of Study: As mentioned in the question, macroeconomics examines topics such as:
   • Unemployment: Understanding the causes and consequences of unemployment rates in an economy.
   • Inflation: Studying the factors that lead to changes in price levels over time.
   • Economic Growth: Analyzing what drives growth in national income and GDP.
   • Other economy-wide phenomena: These include national income, gross domestic product (GDP), and overall economic performance.
3. Contrast with Microeconomics: Unlike macroeconomics, microeconomics focuses on individual markets and the decisions of individual consumers and firms. It deals with supply and demand in specific industries, price mechanisms, and consumer behavior.

Therefore, the principles and topics being discussed by the lecturer and student clearly align with the study of macroeconomics.
