Study Notes
General Microeconomics Principles
- Economics is the science of how to allocate scarce resources among numerous competing needs and wants. Goods, services, and resources need to be expended.
- Economic analysis aims for efficient resource use to maximize human satisfaction.
- Economic study includes various components: what goods to produce; how to produce; how much to produce; and who receives the produce.
- This involves interactions between individuals, firms, markets, and government policy.
Economic Models and Theory
- A theory provides a systematic explanation for an economic phenomenon.
- A model simplifies reality, extracting essential features for predictions.
- Economic models often draw on mathematics to represent relationships between various economic variables.
- Economic theories are tested against observed data, and refined or discarded as better explanations are developed. Models are simplified pictures of reality.
- There are certain common assumptions embedded in economic models.
Positive vs. Normative Economics
- Positive economics describes what is, including how the economy currently functions and how changes affect outcomes. Objective, factual.
- Normative economics refers to what ought to be, examining values and expressing opinions about policies and outcomes. Subjective, opinion-based.
Economic Fallacies
- False-cause fallacy: events correlate but don't necessarily mean causality.
- Fallacy of composition: what's true for one portion may not be true for the whole.
- Ceteris paribus fallacy: must consider only two variables for a relationship to be established.
Graphing in Economics
- Graphs are visual representations of economic relationships.
- Independent variables are often shown on the horizontal axis (x-axis), and dependent variables are shown on the vertical axis (y-axis).
- Slopes, intercepts, and equations are all part of depicting these relationships visually.
Intermediate and Final Goods, Markets
- Intermediate goods are used in the production of other goods.
- Final goods are produced for consumption.
- Markets are arrangements for exchange of goods and services. These exchanges can be categorized by the goods being exchanged, geographic location, type of transaction, etc.
- Market structure describes characteristics like number of buyers/sellers, type of goods/services, and ease of entry/exit in the market to help explain market behavior.
Market Structures
- Perfect competition: many firms, no market power.
- Monopolistic competition: many firms, differentiated products.
- Oligopoly: few large firms, some market power.
- Monopoly: single firm, significant market power.
Elasticity of Demand and Supply Curve
- Elasticity measures how responsive quantity is to changes in other variables (price or income).
- Price elasticity of demand measures how responsive quantity demanded is to changes in price.
- Determinants of PED include availability of substitutes, nature of good (luxury or necessity), time horizon, and income effects.
- The concept of elasticity clarifies the relationship between price and quantity in a market.
Income Elasticity of Demand
- Income elasticity measures how responsive quantity demanded is to changes in income.
- Normal goods (positive elasticity) and inferior goods (negative elasticity) are differentiated by their responsiveness to income changes.
Cross-Price Elasticity of Demand
- Cross-price elasticity relates the responsiveness of demand of one good to the price of another related good.
- Substitutes show positive cross-price elasticity, while complements show negative cross-price elasticity.
Consumer Choice Theories
- The consumer is assumed to be rational and seeks maximum satisfaction, given their income and prices.
- Cardinal utility theory postulates that utility can be measured numerically and ranked.
- Ordinal utility theory suggests that utility cannot be measured numerically but ranked, via indifference curves. Consumers rank bundles of goods from most preferred to least.
Marginal Utility and Consumer Equilibrium
- Marginal utility (MU) is the extra satisfaction gained from consuming one more unit of a good.
- Consumers maximize utility at a point where the marginal utility per dollar spent on each good is equal; MU₁/P₁ = MU₂/P₂.
Budget Constraints and Equilibrium
- The consumer's budget constraint represents the limitations on purchases due to income and prices.
- Graphically, the constraint is a straight line called a budget line or a budget constraint.
- Equilibrium occurs where the budget line is tangent to the highest attainable indifference curve, satisfying the conditions for utility maximization, subject to the consumer's income and prices faced.
- A change in income or prices will shift the budget line, causing a change in the optimal consumption bundle.
Production Function Analysis
- The production function shows the maximum level of output that can be achieved with various combinations of inputs (labor, capital, etc.).
- Inputs and outputs are related technically.
- The short-run considers a fixed input (capital), while the long-run permits all inputs to be varied.
- Efficiency describes the relationship between inputs and output, allowing for differences in productive methods.
- Marginal productivity is the change in output resulting from a one-unit increase in a particular input.
- Marginal Rate of Technical Substitution (MRTS) measures how much of one input must be reduced to accommodate a one-unit increase in another, while holding output constant.
