The Law of Increasing Opportunity Costs
The principle that the opportunity cost increases as production of one output expands.
This is responsible for the “bowed shape” of the PPC.
Reasoning
• not all workers are equally suited to producing one good , compared to another.
• as we shift production levels of butter, we gradually tap into the best gun-making resources
Marginal Analysis
An examination of the effects of additions to or subtractions from a current situation.

Production Possibilities Curve — Movements and Shifts
Shifts in the PPC
Changes (increases) in the levels of a country’s LLC will cause the PPC to shift from PPC1 to PPC2
Movements along the PPC
Changes in the needs and wants cause a country to choose a different point along an existing PPC
