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.
