PRODUCTION POSSIBILITIES Assumes... Full Employment Productive Efficiency Fixed Resources Fixed Technology Two Goods for example...

Q Q Robots (thousands) Pizzas (hundred thousands) A B C D E W Attainable but Inefficient Unattainable Attainable & Efficient PRODUCTION POSSIBILITIES

Law of Increasing Opportunity Cost Economic resources are not completely adaptable to other uses so to make more of one good, it costs more and more of the other good. It’s what PPCs are concave.
