Exam 1 Study Guide: Microeconomics
Overview
This study guide outlines the essential topics and concepts to review for Exam 1 in a college-level Microeconomics course. It is organized by textbook chapters and highlights important areas, including definitions, problem-solving, and key economic models.
Chapters 1 and 2
General Review
Key Point: Review all questions and problems from these chapters to ensure a solid foundation in basic microeconomic principles.
Key Point: Understand fundamental concepts such as scarcity, opportunity cost, and the role of incentives in economics.
Example: Opportunity cost is the value of the next best alternative foregone when making a decision.
Chapter 3
Supply and Demand
Key Point: Read the chapter thoroughly and review all questions and problems.
Key Point: Understand the laws of supply and demand, market equilibrium, and the effects of shifts in supply and demand curves.
Example: An increase in demand shifts the demand curve to the right, raising equilibrium price and quantity.
Additional info: Make sure you understand problems 13 and 14, which may involve advanced applications of supply and demand analysis.
Chapter 4
Elasticity
Key Point: Read the chapter and review all questions and problems.
Key Point: Pay attention to elasticity concepts, including price elasticity of demand, income elasticity, and cross-price elasticity.
Formula: Price elasticity of demand:
Example: If the price of a good increases by 10% and quantity demanded decreases by 20%, the price elasticity of demand is .
Additional info: Review problems 13 and 14 for deeper understanding of elasticity calculations and interpretations.
Chapter 5
Consumer and Producer Surplus
Key Point: Read the chapter and review all questions and problems, focusing on problems 1, 2, 5, 6, 8, 10, and 13.
Key Point: Understand the concepts of consumer surplus and producer surplus, and how they are represented graphically.
Formula: Consumer Surplus:
Formula: Producer Surplus:
Example: If a consumer is willing to pay $10 for a product but pays $7, the consumer surplus is $3.
Chapter 6
Production and Costs
Key Point: Read the chapter and review all questions and problems, especially problems 1, 2, 5, 6, 8, 10, and 13.
Key Point: Understand the cost of production, including how to replicate and explain cost curves and charts (e.g., Exhibit 6.3).
Key Point: Learn the definitions and differences between fixed costs, variable costs, total cost, average cost, and marginal cost.
Formula: Total Cost:
Formula: Marginal Cost:
Example: If total cost increases from MC = \frac{20}{2} = 10$ per unit.
Additional info: Exhibit 6.3 likely refers to a graphical representation of cost curves; be prepared to explain and replicate such charts.
Chapter 7
Competitive Markets and Firm Behavior
Key Point: Review all questions and problems, focusing on problems 1, 2, 3, 10, 11, 12, and 13.
Key Point: Understand the definition of a competitive market, including characteristics such as many buyers and sellers, homogeneous products, and free entry and exit.
Key Point: Learn how price and production are determined for a single firm and for the entire market in both the short run and long run.
Formula: Profit Maximization Condition:
Example: In a perfectly competitive market, firms produce where marginal cost equals market price.
Additional info: Be able to distinguish between short-run and long-run market adjustments, including entry and exit of firms.
