Study Notes
Economics - General Concepts
- Economics studies how individuals, firms, and societies allocate scarce resources to meet unlimited wants and needs.
- An economic model is a simplified representation of reality used to understand, explain, and predict economic behaviors and outcomes.
- An economy facilitates the allocation of resources, production of goods and services, and distribution among society members.
Opportunity Cost
- Opportunity cost is the value of the next best alternative foregone when a choice is made.
- Example: Spending $10 on a movie ticket means forgoing the opportunity to spend that money on another item, such as a book or meal.
Utility
- Marginal utility typically decreases as consumption of a good increases.
- Total utility initially increases, then increases at a slower rate, and may eventually decline if consumption leads to dissatisfaction.
Cost Curves
- Fixed costs do not change with output levels (e.g., rent, insurance).
- Variable costs change with the level of output.
- Total costs include both fixed and variable costs.
Production
- A production function shows the relationship between inputs (e.g., labor, capital) and output.
- Diminishing marginal returns occur when the marginal gain in output diminishes as each additional unit of input is added.
Market Structures
- Perfect competition: Many firms, homogeneous products, low barriers to entry.
- Monopolistic competition: Many firms, differentiated products, low to moderate barriers to entry.
- Oligopoly: Few firms, interdependent decision-making, high barriers to entry.
- Monopoly: One firm, unique product, high barriers to entry.
Market Equilibrium
- Equilibrium price and quantity are where supply and demand intersect.
- If demand and supply increase, the equilibrium quantity may increase or decrease depending on the relative magnitude of the shifts.
- A price floor is typically set above the equilibrium price and results in a shortage.
- A price ceiling is typically set below the equilibrium price and results in a surplus.
Factors of Production
- Land: Natural resources
- Labor: Human effort
- Capital: Tools, machinery, and infrastructure
- Entrepreneurship: Organizational and risk-taking ability
Demand and Supply
- The law of supply states the higher the price, the higher the quantity supplied (ceteris paribus).
- The law of demand states the lower the price, the higher the quantity demanded (ceteris paribus).
Economic Models and Concepts
- Scarcity: Limited resources while infinite wants.
- Trade-offs: Choosing one option over another.
- Opportunity costs: The value of the next best alternative.
- Utility: Total satisfaction or benefit from consuming goods, services, or leisure.
- Marginal utility: Extra satisfaction from consuming one more unit.
- Market Failures: situations where a market does not operate efficiently (e.g., monopolies).
- Nash Equilibrium : a situation in which no player can improve their outcome by changing their strategy while other players stay the same.
