🔹 2. Central Economic Problems

Because resources are limited and human wants are unlimited, every economy faces three fundamental questions:

1. What to produce?
   • Deciding which goods and services should be produced and in what quantity.
2. How to produce?
   • Choosing the method of production (labor-intensive or capital-intensive).
3. For whom to produce?
   • Deciding how goods are distributed among individuals and groups in society.
