The Economic Problem PPC’s and the Law of Increasing Costs
Production Possibility Curve • A visual demonstration of what can be produced given the limited amount of resources available • PPC’s demonstrate opportunity costs as you move along the curve and decide to produce one good vs. another
Straight Line PPC • A Straight Line PPC assumes the following: • homogeneous inputs to the production process • same material, identical tools, and • labour that is equally skilled for both products • similar outputs – ie. Leather pants and leather • moccasins
Concave PPC • For a Concave PPC: • opportunity costs increase as you produce more of one product • this is called the Law of Increasing Costs
Concave PPC • Law of Increasing Costs • As the production of any single item increases, the per unit cost of producing additional units of that item will rise • Why? • not all resources are equally suitable for the production of different products. • ie. Links and Smiles example • ie. Switching Sports example • Therefore a larger quantity of less suited resources will need to be reallocated to obtain the extra production of the other good, causing the opportunity cost to rise.
