Summary of Chapter
- Needs are the things essential for survival, while wants are not essential but improve our quality of life.
- Human wants are unlimited and keep changing, but our resources are limited in quantity.
- This gap between unlimited wants and limited resources is called scarcity , and it forces us to choose.
- The problem of choice is deciding how to allocate limited resources among their many alternative uses.
- When one option is picked, another is given up, and the value of what is given up is the opportunity cost .
- The Production Possibility Curve shows the trade-off between two goods made with the same resources.
- Economics studies how consumers, producers, governments and financial institutions make these choices, using data rather than guesswork.
- Every economy must answer three key questions - what to produce , how to produce , and for whom to produce .
- Production may be labour-intensive or capital-intensive , depending on costs, technology, the nature of the product and the law.
- A planned economy , a market economy and a mixed economy answer these questions differently, and almost all economies today are mixed .
