Study Notes
Consumer Behavior
- Rational Choice Theory: assumes consumers make rational decisions to maximize their utility (satisfaction) given their budget constraint
- Budget Constraint: a graphical representation of the combinations of two goods that a consumer can afford to buy
- Indifference Curves: show different combinations of two goods that provide the same level of utility
- Demand Theory: studies how consumer behavior responds to changes in price and income
- Law of Diminishing Marginal Utility: the additional utility gained from consuming one more unit of a good decreases as the quantity consumed increases
Market Equilibrium
- Market Equilibrium: a state where the quantity of a good or service that consumers are willing to buy (demand) equals the quantity that producers are willing to supply
- Equilibrium Price: the price at which the demand and supply curves intersect
- Surplus: a situation where the quantity supplied exceeds the quantity demanded
- Shortage: a situation where the quantity demanded exceeds the quantity supplied
- Adjustments to Equilibrium: changes in price and quantity in response to changes in demand or supply
Supply and Demand
- Law of Supply: as the price of a good increases, the quantity supplied also increases, ceteris paribus
- Law of Demand: as the price of a good increases, the quantity demanded decreases, ceteris paribus
- Supply Curve: a graphical representation of the relationship between price and quantity supplied
- Demand Curve: a graphical representation of the relationship between price and quantity demanded
- Shifts in Supply and Demand: changes in the supply or demand curve in response to changes in factors other than price
Production Theory
- Firm's Objective: to maximize profits by minimizing costs and maximizing revenue
- Production Function: a mathematical representation of the relationship between inputs (labor and capital) and output
- Marginal Product: the additional output generated by one additional unit of a variable input (e.g. labor)
- Marginal Cost: the additional cost generated by one additional unit of output
- Average Cost: the total cost divided by the total output
- Economies of Scale: reductions in average cost as the firm increases its scale of production

Market Equilibrium
- Market Equilibrium occurs when the quantity of a good or service that consumers are willing to buy (demand) equals the quantity that producers are willing to supply
- Equilibrium Price is the price at which the demand and supply curves intersect
- Surplus occurs when the quantity supplied exceeds the quantity demanded
- Shortage occurs when the quantity demanded exceeds the quantity supplied
- Adjustments to Equilibrium involve changes in price and quantity in response to changes in demand or supply
Supply and Demand
- Law of Supply states that as the price of a good increases, the quantity supplied also increases, ceteris paribus
- Law of Demand states that as the price of a good increases, the quantity demanded decreases, ceteris paribus
- Supply Curve is a graphical representation of the relationship between price and quantity supplied
- Demand Curve is a graphical representation of the relationship between price and quantity demanded
- Shifts in Supply and Demand occur in response to changes in factors other than price

- A firm's objective is to maximize profits by minimizing costs and maximizing revenue
- Production Function is a mathematical representation of the relationship between inputs (labor and capital) and output
- Marginal Product is the additional output generated by one additional unit of a variable input (e.g. labor)
- Marginal Cost is the additional cost generated by one additional unit of output
- Average Cost is the total cost divided by the total output
- Economies of Scale refer to reductions in average cost as the firm increases its scale of production
