Thinking Like An Economist by Randall Bartlett

This concise primer introduces readers to the economist’s way of thinking, emphasizing trade-offs, opportunity cost, marginal analysis, and the role of incentives in shaping behavior. It shows how simple models and clear assumptions help clarify problems, predict responses to policy or market changes, and distinguish situations where markets allocate resources efficiently from those that generate failures (externalities, public goods, information problems). The book focuses on practical applications for everyday decision-making and public policy, offering tools for disciplined reasoning while acknowledging the limits of models and the need for empirical validation.
