Key ideas in How the Economy Works
- Economic resources like money, land, and labor are always finite, even during periods of surplus
- Choosing to allocate funds toward one project inherently means those same dollars cannot fund something else, creating an unavoidable trade-off
- Opportunity cost is only the value of the single next-best alternative you surrender
- You cannot add up every alternative choice, because you could not have done all of them at once anyway
- Even profitable choices carry an opportunity cost in the form of foregone alternatives
- Money already spent that cannot be recovered is a sunk cost
- Sound economic choices depend only on future expected costs and future revenues, not past outlays
- Throwing more resources into a losing project just to 'justify' past spending results in greater overall loss
- Marginal decisions compare the additional benefit (marginal benefit) of one more unit to its additional cost (marginal cost)
- Past averages do not determine whether the next step is worth taking; only the next increment matters
- As long as marginal benefit exceeds marginal cost, taking that next step is profitable
- Incentives shift behavior predictably by changing the relative prices, costs, or payoffs of choices
- Raising the direct cost of an activity (like peak tolls) discourages it, while lowering the cost of substitutes (like cheap transit) encourages alternatives
- Vague moral appeals do not change underlying economic costs or payoffs and tend to have little reliable effect on behavior
- A price aggregates costs, harvest conditions, and consumer appetite into a single readable number
- Buyers do not need to track why a good got harder to supply; the price alone tells them it is scarcer
