This production possibilities curve or frontier indicates the combinations of laptops and mobile phones that are attainable (can be produced) when Zanadu's resources are fully and efficiently used. Note that any point on the production possibilities curve is a possible combination, but we will only focus on points A, B, C, D, E and F.
Because the curve shows all the different possible combinations, and because it takes into account all the available resources and its efficiencies, it shows the boundaries (limits) of production possibilities for producing two goods. It represents the potential output of Zanadu.
It is important that you have a very good understanding of the production possibilities curve since we will be using it to explain scarcity, choice, efficiency, inefficiency and opportunity costs.
