**What This Document Is**
These are lecture notes from the first semester of Microeconomic Principles (ECON 103) at George Mason University, covering material from the first week of classes in 2022. The notes lay foundational groundwork for understanding how economies function, focusing on the price system as an information mechanism and the core assumptions underpinning economic thought. They also begin a historical overview of price theory, starting with Aristotle and progressing through Mercantilism and the Classical School.
**Why This Document Matters**
These notes are essential for students enrolled in ECON 103 seeking a concise record of the initial lectures. They are most valuable when used as a study aid to reinforce concepts presented in class and prepare for subsequent topics. Understanding these early principles is crucial for grasping more complex economic models later in the course. Anyone interested in the historical development of economic thought will also find value in the overview provided.
**Common Limitations or Challenges**
These notes are a *record* of lectures, not a substitute for attending class or engaging with assigned readings. They represent a specific instructor’s presentation and may not encompass all nuances of the topics. The notes are incomplete and do not cover all aspects of microeconomic principles. They are a starting point, not a comprehensive resource.
