Final answer:
Macroeconomics focuses on economic aggregates and analyzes the behavior of the economy as a whole. The actions of individuals at the micro level may differ from what happens at the macro level. Crowd behavior can help explain this divergence.
Step-by-step explanation:
Macroeconomics focuses on economic aggregates that summarize data across many different markets. It looks at the economy as a whole, analyzing broad issues such as growth, unemployment rates, inflation, and government deficits. The behavior of economic agents at the micro level, such as households, workers, and businesses, may not always align with what happens at the macro level. This can be explained by the concept of crowd behavior, where the actions of individuals may not always reflect the collective behavior of the group.
