Study Notes
Consumer Behaviour
- Utility is the want-satisfying power of a good or service.
- Utility is not the same as usefulness.
- Utility is subjective and difficult to quantify.
Utility Analysis
- The purpose of utility analysis is to understand how people make purchase decisions, rather than how they think.
- Theory of consumer choice = how consumers spend their income to achieve maximum satisfaction.
- Utility = the amount of satisfaction gained from consuming a good or service.
Total vs. Marginal Utility
- Total utility = total benefit a consumer receives from all units of a good purchased.
- Marginal utility = extra benefit from last unit of a good purchased. This is the change in total utility after buying one more unit.
- As more units of a good are consumed, total utility increases but marginal utility decreases.
Total and Marginal Utility - Tacos Example
-
Table shows total and marginal utility values for consuming tacos, varying with quantity consumed.
-
Graph shows total utility curve increasing up to 5 tacos, and then flattening/decreasing. Marginal utility curve similar but peaks at one taco.
Law of Diminishing Marginal Utility
- Marginal utility declines as more units of a good are consumed.
- The value of additional units decreases. (e.g., the second car is less desirable than the first)
Using Marginal Utility
- Optimal Purchase Rule: Buy the quantity of each good where price equals marginal utility.
- If marginal utility is higher (lower) than price, the consumer should buy more (less) of that good.
Marginal Utility and Demand
- The law of diminishing marginal utility implies a downward-sloping demand curve.
- As price increases, quantity demanded decreases, leading to increased marginal utility.
Consumer Choice and Budget Constraint
- Consumers aim to maximize total utility.
- Consumers face clear-cut preferences.
- Consumers have limited income (budget constraint).
- Every good has a price.
Consumer Choice and Opportunity Cost
- The decision to purchase one good comes at the cost of forgoing something else.
- Opportunity cost of spending a dollar on one good is the utility sacrificed from purchasing a different good.
Utility Maximizing Rule
- Consumer allocates income so that the last cent spent on each product generates the same marginal utility.
Utility Maximizing Combination
- Table shows data for a consumer facing a choice between two products (MU of Product A and B, per price).
- Optimal Allocation: consumer's purchase strategy maximizes satisfaction (highest possible level of utility).
- Tables demonstrate how to derive the optimal combination given the budgets and relative prices of the two products.
Calculating Marginal Net Utility (Consumer Surplus)
- The difference between the maximum willingness to pay vs. the price paid.
Consumer Surplus - Graphical
- The area below the demand curve and above the price line up to the quantity purchased.
Producer Surplus
- Difference between the actual price a producer receives and the minimum acceptable price.
- Graphically, it's the area above the supply curve and below the price line up to the quantity sold.
Resolving the Diamond-Water Paradox
- Although water has greater total utility, diamonds have a higher marginal utility due to scarcity.
- Prices reflect marginal utility, not total utility.
Indifference Curves
- All consumption bundles offering equal satisfaction.
- Higher indifference curves represent greater satisfaction.
- Never intersect; indifference curves slope downward and are bowed in.
Properties of Indifference Curves
- Higher is better - a higher indifference curve represents greater overall satisfaction.
- Convex - curves representing this preference for a combination of goods.
- Indifference curves never intersect.
Budget Line Properties
- Shows maximum combinations of goods that a consumer can afford.
Changes in Budget Line
- Income changes = parallel shifts.
- Relative price changes = changes in slope.
Utility Maximization and Demand Curve
- Derive the demand schedule.
- Plot points and create a curve as prices vary
