Economic problem
a problem based on the problem of scarcity i.e. when there are UNLIMITED WANTS but FINITE RESOURCES with which to SATISFY them. Therefore, choices have to be made and resources have to be allocated between competing uses

Renewable resource
natural resources that can be replenished e.g. solar energy that does not get used up
The catch with renewable resources
renewable resources may decline over time if consumed at a faster rate than the environment can replenish them
non-renewable resources
natural resources that once used cannot be replenished e.g. coal or oil
a PPF
a Production Possibility Frontier is a curve showing the maximum potential output for two goods or services that an economy can achieve when all its resources are fully and efficiently employed
marginal costs
the cost of producing an additional unit of output
opportunity cost w/ a straight line PPF
opportunity cost of a straight line PPF is constant b/c resources are of equal quality and equally suited to the production of both goods
opportunity cost w/ concave line
the opportunity cost increases = the more of one good is produced, an increasing amount of the other good is forgone b/c not all resources are as efficient as other resources in the production of both goods = diminishing returns (after a period of time, you gain less return for the same input)
