**What This Document Is**
These are lecture notes from EC 101, Microeconomics at Boston University, taught by Professor Idson. The notes cover the foundational principles of economics, beginning with the core problem of scarcity and resource allocation. They then transition into how economists approach problems – both as scientists building models and as policy advisors. The notes also introduce the fundamental distinction between microeconomic and macroeconomic study.
**Why This Document Matters**
These notes are essential for students enrolled in Professor Idson’s EC 101 course. They provide a concentrated overview of the key concepts discussed in the first two lectures, serving as a valuable study aid and reference point. Understanding these ten principles is crucial for anyone beginning their study of economics, as they form the basis for more advanced topics. They are particularly useful for students preparing for quizzes or exams covering introductory economic thought and modeling.
**Common Limitations or Challenges**
These notes are a *summary* of lectures, not a substitute for attending class or completing assigned readings. They provide the framework of ideas but do not offer in-depth explanations or detailed examples beyond those presented in the lectures. The notes also do not include problem sets or practice questions. A strong grasp of these concepts requires further study and application.
