1. **Production Possibilities Curve (PPC):** The PPC is a model that visually represents the trade-offs between two goods in an economy, demonstrating the concept of scarcity[1%20is%20a%20model%20that%20captures,beyond%20the%20PPC%20are%20unattainable.)][3][4].
2. **Scarcity and Efficiency:** Points on the PPC reflect efficiency, while points inside are inefficient, illustrating that resources are not fully utilized. The downward slope indicates scarcity - as production of one good increases, the other must decrease[2][5].
3. **Opportunity Cost:** The PPC demonstrates opportunity cost by showing the trade-off between producing one good over another. Moving along the curve involves sacrificing one good for the other, highlighting the concept of opportunity cost[6].
In summary, the PPC serves as a visual tool to understand the interplay of scarcity, efficiency, and opportunity cost in decision-making within an economy.
