Captions available
The idea
The production possibilities frontier shows the combinations of two products an economy can produce. It curves outward. Points outside are unattainable; points inside are wasteful; a growing economy shifts it outward. The law of diminishing returns explains the curve: added resources yield smaller output gains.
In practice
Guns and butter.
Where people slip
The glossary says marginal benefit; the summary's output form governs.
