Study Notes
Utility and Demand
- Utility represents consumer satisfaction from consuming goods and services.
- Total utility is the overall satisfaction from consumption, while marginal utility is the extra satisfaction from one more unit.
- Diminishing marginal utility means marginal utility decreases as consumption increases.
- A consumption choice is determined by a consumer's budget (what they can afford) and preferences (their likes and dislikes).
- A budget line shows combinations of goods a consumer can purchase with their income. Its slope represents the relative price of goods.
- Price or income changes shift the budget line.
- Consumers maximize utility by equalizing marginal utility per dollar spent on all goods. This is known as Consumer Equilibrium.
- Marginal utility per dollar (MU/P) measures the additional utility gained from spending an extra dollar on a good.
- The utility-maximizing rule states that consumers buy more of a good when its MU/P is higher than other goods.
- Marginal utility theory predicts that demand increases when prices fall (MU/P increases), and vice versa. It also predicts that demand for normal goods decreases as income decreases.
Preferences, Possibilities, and Choices
- Preferences are represented by indifference curves, showing combinations of goods giving equal satisfaction.
- A budget equation relates total income to spending on goods, representing the budget constraint.
- The relative price is the price of one good in terms of another and reflects the opportunity cost of choosing one good over another.
- Indifference curves help understand consumer preferences and trade-offs between goods. The slope of an indifference curve represents the marginal rate of substitution (MRS), which is the rate at which a consumer is willing to give up one good for another while maintaining the same utility level.
- The best affordable choice is where the highest attainable indifference curve touches the budget line, meaning the MRS equals the relative price.
- Price changes influence consumption through substitution and income effects. For example, a price drop in a good can lead to more consumption of that good due to both effects.
Public Choices, Public Goods, and Healthcare
- A public good is non-rivalrous (one person's use doesn't affect another's) and non-excludable (people can't be prevented from using it). Examples include national defense.
- Government intervention is necessary for public goods because of the free-rider problem, where individuals enjoy benefits without contributing financially.
- Government failures can occur in public goods provision.
- Public choices are decisions made by government regarding resource allocation and public good provision.
- Governments exist to provide public goods, address market failures, and enforce property rights.
- Rational ignorance describes voters' limited information about policy due to high information-gathering costs.
- The government intervenes in healthcare and education due to positive externalities.
- Healthcare faces market failures due to high costs, information asymmetry, and difficulty in defining the product.
- Marginal social benefit (MSB) is the total benefit to society from consuming an additional unit of a good, calculated as MPB + MEB.
Externalities
- An externality is a cost or benefit of a transaction that affects third parties not involved in the transaction.
- Negative externalities impose costs on others, like pollution. Positive externalities benefit others, like vaccinations.
- Marginal social cost (MSC) is the total cost to society of producing an additional unit, calculated as MPC + MEC.
- Properly defined and enforceable property rights, along with low transaction costs, can help address externalities through private bargaining, according to the Coase theorem.
- Governments use regulations, taxes, subsidies, and tradable permits to control pollution.
