Study Notes
Consumer Choice
- Consumers make purchasing decisions based on their preferences, budget constraints, and desire to maximize utility.
- Preferences are expressed by ranking bundles of goods based on utility or satisfaction.
- Indifference curves represent combinations of goods that provide the same satisfaction.
- Marginal Rate of Substitution (MRS) reflects the willingness to trade one good for another while maintaining the same satisfaction.
- Budget constraints limit the purchasing power based on income and prices of goods and services.
- Budget line represents all possible combinations of two goods a consumer can purchase with their income.
- Shifts in the budget line occur due to changes in income or prices.
- Utility maximization involves choosing the combination of goods that maximizes satisfaction given budget constraints.
- Utility function mathematically represents consumer preferences.
- Optimal choice occurs where the highest indifference curve is tangent to the budget line, meaning the MRS equals the price ratio.
Impact of Changes in Income and Prices
- Income increase: shifts the budget line outward, increasing quantities of normal goods and possibly affecting consumption of inferior goods.
- Income decrease: shifts the budget line inward, reducing quantities of most goods.
- Price increase: rotates the budget line inward, reducing the quantity affordable. This leads to a decrease in demand due to the substitution effect (shifting to cheaper alternatives) and income effect (feeling poorer and buying less).
- Price decrease: rotates the budget line outward, increasing the quantity affordable, leading to an increase in demand due to the substitution and income effects
Demand Theory
- Explains how consumer purchasing decisions are influenced by prices and other factors.
- Law of Demand: states that as price decreases, quantity demanded increases, and vice versa.
- Rationale: This inverse relationship stems from the substitution effect (switching to cheaper alternatives) and the income effect (feeling richer and buying more).
- Demand Curve: a graphical representation of the relationship between price and quantity demanded.
- It is typically downward sloping, showing the inverse relationship.
- Demand Schedule: a table listing the quantities demanded at different prices.
Factors Affecting Demand
- Besides price, demand is influenced by:
- Income: An increase generally increases demand for normal goods and decreases demand for inferior goods.
- Prices of Related Goods: Prices of substitutes and complements affect demand.
- Consumer Preferences: Changes in tastes and preferences can shift demand.
- Expectations: Future expectations about prices or income influence current demand.
- Number of Buyers: More consumers in the market can increase overall demand.
Forecasting Market Demand
- Demand Function: mathematically represents the relationship between quantity demanded, price, and other factors.
- Price Elasticity of Demand: measures how sensitive quantity demanded is to price changes.
- Inelastic Demand: ∣Ed∣< 1, meaning a change in price has a relatively small effect on quantity demanded.
- Elastic Demand: ∣Ed∣> 1, meaning a change in price has a relatively large effect on quantity demanded.
- Unit Elastic Demand: ∣Ed∣= 1, meaning a change in price has an equal proportional effect on demand.
