Course Introduction
Principles of Economics introduces students to the fundamental concepts and theories that form the basis of economic analysis. The course covers both microeconomics focusing on individual consumers, firms, market structures, and resource allocation and macroeconomics, which addresses topics such as aggregate economic activity, inflation, unemployment, fiscal and monetary policy, and economic growth. Through real-world examples and theoretical frameworks, students will learn how economic principles apply to everyday decision-making and public policy, laying the groundwork for advanced study in economics and related fields.
