Basic Economics

"Economics is the study of the use of scarce resources which have alternative uses."
— Basic Economics (2000)

Core Concept

Economics isn't about money - it's about making choices under constraints. Every decision we make involves trade-offs, because:

  • Resources are limited
  • Wants are unlimited
  • Every resource has alternative uses

Three Fundamental Questions

Every economic system must answer:

  1. What to produce?
  2. How to produce it?
  3. Who gets what is produced?

Key Principles

1. Incentives Matter

"No one will ever work as hard for your interests as they will work for their own."
— Knowledge and Decisions (1980)

People respond to incentives. When prices rise, people buy less. When wages rise, more people seek those jobs. This isn't about greed - it's about human nature.

2. There Are No Solutions, Only Trade-offs

"There are no solutions. There are only trade-offs."
— A Conflict of Visions (1987)

Every decision has:

  • Benefits and costs
  • Winners and losers
  • Intended and unintended consequences

3. Prices Convey Information

"Prices are important not because money is considered paramount but because prices are a fast and effective conveyor of information through a vast society in which fragmented knowledge must be coordinated."
— Knowledge and Decisions (1980)

Real-World Application

Let's take a simple example: The Price of Coffee

When coffee crops fail in Brazil:

  1. Prices rise
  2. Consumers buy less coffee
  3. Some switch to tea
  4. Farmers elsewhere plant more coffee
  5. Resources shift automatically

No central planner needed to:

  • Tell people to conserve coffee
  • Direct farmers what to plant
  • Decide who gets how much

Think It Through

Consider this scenario:

Your city bans "price gouging" during a natural disaster, keeping water prices at normal levels. What are the:

  • Intended consequences?
  • Unintended consequences?
  • Trade-offs involved?

Key Takeaways

  1. Economics is about trade-offs, not money
  2. Incentives drive human behavior
  3. Prices communicate information
  4. Good intentions ≠ Good results
  5. Consider both seen and unseen effects
