Study Notes
Introduction to Economics
- Economics is the study of how societies use scarce resources to satisfy unlimited wants and needs.
- Three reasons to study economics:
- Develop critical thinking skills
- Understand societal structures
- Become an informed citizen
Scarcity, Choice, and Opportunity Cost
- Scarcity: Limited resources, unlimited wants.
- Choice: A necessary result of scarcity
- Opportunity cost: The value of the next best alternative forgone when a choice is made
Factors of Production (Resources)
- Land: Natural resources (e.g., land, minerals, water)
- Labor: Human effort and skills
- Capital: Man-made resources used in production (e.g., tools, machinery, factories).
Production Possibility Frontier (PPF)
- PPF: A curve/graph depicting all possible combinations of output for two goods or services using all available resources efficiently
- Its slope represents the opportunity cost of producing one good over another
Economic Systems
- Command Economy: Government controls the factors of production (e.g., output, prices).
- Market Economy: Individuals and firms own resources and pursue self-interest.
- Mixed Economy: An economy that combines characteristics of command and market economies (e.g., US).
Demand and Supply
- Demand: The relationship between a good's price and the amount consumers are willing to buy.
- Law of Demand: Higher prices lead to lower quantities demanded (and vice versa).
- Supply: The relationship between a good's price and the amount producers are willing to sell.
- Law of Supply: Higher prices lead to higher quantities supplied (and vice versa).
- Market Equilibrium: Where supply and demand curves intersect; The price where quantity supplied = quantity demanded.
Elasticity
- Elasticity: The responsiveness of one variable to a change in another variable.
- Price Elasticity of Demand: Responsiveness of quantity demanded to a change in price.
- Price Elasticity of Supply: Responsiveness of quantity supplied to a change in price.
- Determinants of Elasticity: Availability of substitutes, time, and proportion of income spent on the good.
Total Revenue
- Total Revenue = Price × Quantity
- The relationship between price changes and total revenue depends on the elasticity of demand.
