   Goods/services are scarce b/c the resources used to produce them are scarce Only so many natural resources available to produce goods Labor for production can be limited   Physical capital can be limited for many industries Each resource may have alternative uses  People, businesses, govt.s must choose which alternative they want most

M

ARGIN  Marginal Costs and Benefits   To make good decisions you must weigh the marginal costs against marginal benefits   M.Cost = extra cost of adding one unit such as sleeping or getting one more cookie M. Benefit = extra benefit from adding one unit such as sleeping or getting one more cookie Once the marginal costs outweigh the marginal benefit, no more units can (or will) be added   Example: 1 more cookie is o.k. b/c it is only 35 more calories but once the unit cost (calories) exceeds what the benefit (satisfaction) is you will not add anymore.

Best example is how often you tell yourself you can “sleep just ____ much longer” before there is a cost you aren’t willing to put up with

   To help decisions, economists use PPCs as a tool  Curve helps nation’s economists determine alternative ways of using a nation’s resources Production Possibilities  Economists use graphs to analyze choices/trade-offs that people make  To draw PPC, begin by deciding which goods/services to examine.

 Refer to graph, pg. 14 Production Possibilities Frontier   Line that shows the maximum possible output an economy can produce Each point reflects a trade-off  Happens b/c factors of production are scarce  L, L, and C to make one product means fewer of those to make the other

Underutilization Growth

 When an economy grows the curve shifts to right  Production capacity can also decrease, leading to shift left Cost: Can help show the opportunity costs of Decisions   Cost increases as production shifts from making one item to another Law of Increasing Costs: Refer to Chart pg. 17  Explains as we move along the curve, we trade off more & more for less & less output
