What is Economics?

Summary

In this engaging lecture, Professor Mark Perky from North Carolina A&T State University demystifies economics, explaining it as the study of choices and scarcity rather than just money or finance. He highlights the two main branches of economics: microeconomics, which focuses on individual and business choices, and macroeconomics, which examines the overall economy through metrics like GDP, unemployment, and inflation. The concept of rational maximization is introduced, emphasizing the importance of weighing costs and benefits in decision-making to maximize happiness for individuals and profits for businesses. Future lectures promise deeper insights into these economic principles.
