Understanding Key Concepts in Econ 101 Exam 1
Success in your exam hinges on a solid grasp of foundational concepts. Below are the critical ideas you should master:
Scarcity and Opportunity Cost
- Scarcity refers to the limited nature of resources relative to unlimited wants.
- Opportunity Cost is the value of the next best alternative foregone when making a decision.
- Example: Choosing to attend class instead of working a part-time job involves an opportunity cost.
Supply and Demand Fundamentals
- Law of Demand: As price decreases, quantity demanded increases, ceteris paribus.
- Law of Supply: As price increases, quantity supplied increases.
- Market Equilibrium: The point where supply equals demand.
- Shifts in Curves: Influenced by factors like income, preferences, technology, and input prices.
Elasticity
- Measures responsiveness to price changes.
- Price Elasticity of Demand: Percentage change in quantity demanded resulting from a percentage change in price.
- Types:
- Elastic (>1): Sensitive to price changes.
- Inelastic (<1): Less sensitive.
- Perfectly elastic or inelastic: Extreme cases.
Market Failures and Externalities
- Externalities are costs or benefits not reflected in market prices.
- Examples:
- Pollution (negative externality)
- Education (positive externality)
- Market failure occurs when resources are not allocated efficiently.
Market Structures
- Perfect Competition: Many sellers, identical products, free entry/exit.
- Monopoly: Single seller with significant market power.
- Monopolistic Competition: Many sellers, differentiated products.
- Oligopoly: Few sellers dominating the market.
Government Intervention
- Price controls such as ceilings and floors.
- Taxes and subsidies to influence supply and demand.
- Intended to correct market failures or achieve social goals.

Common Challenges and How to Overcome Them
Many students encounter difficulties in understanding or applying economic principles. Recognizing common pitfalls can help avoid mistakes:
1. Confusing Related Concepts
- Differentiate between demand elasticity, supply elasticity, and income elasticity.
- Clarify the distinction between market equilibrium and disequilibrium.
2. Misinterpreting Graphs
- Practice drawing and analyzing supply and demand graphs.
- Understand what shifts and movements along curves signify.
3. Overlooking Key Assumptions
- Remember the assumptions underlying models (e.g., ceteris paribus).
- Recognize limitations of models in real-world applications.
4. Memorization Without Understanding
- Focus on understanding the reasoning behind concepts.
- Use real-world examples to deepen comprehension.

Sample Questions and Practice Exercises
To prepare effectively, practicing with sample questions is invaluable. Here are examples:
Multiple Choice:
1. Which of the following causes a movement along the demand curve?
- a) A change in consumer income
- b) A change in the price of the good
- c) A change in consumer preferences
- d) A change in the price of related goods
Answer: b) A change in the price of the good
Short Answer:
2. Explain the concept of opportunity cost with an example.
Sample Response: Opportunity cost is the value of the next best alternative forgone when making a decision. For example, if you spend time studying economics, the opportunity cost might be missing out on leisure or social activities.
Graphing Exercise:
3. Draw a demand and supply graph showing an increase in demand. Indicate the new equilibrium price and quantity.
