Rationality Assumption People have well-defined goals and try to fulfil them the best they can.
Scarcity Principle No free lunch. Boundless needs and wants.
Concept of Cost • Dollar costs (seen) • Opportunity costs (unseen) • Sunk costs (out of sight—forget about them!)
Cost Benefit Principle An action is taken if marginal benefit exceeds marginal cost.
Eight Principles • Scarcity implies that trade-offs must be made. • People engage in economizing behavior: their actions are guided by a cost-benefit calculation. • People respond to incentives. • Individuals make decisions at the margin. • Information is costly. • Secondary effects are important: “unintended consequences” • The value of a good is subjective. • The test of a theory is its ability to predict.
