The short-run alternation between downturns, or recessions, and economic upturns, expansions
Expansion, contraction, trough, peak
Inflation

Resource

Land, labor, capital, entrepreneurship
Market vs command economy
In market, the decisions of individual producers and consumers determine what to produce
In command, central authority makes production and consumption decisions
Productive efficiency
An economy that produces as much of a good as it can given the production of other goods
Allocative economy
Producing the mix of goods most desired by consumers
Increasing opportunity cost
As more of a good is produced its opportunity cost increases because well-suited inputs are used up and less adaptable inputs must be used instead
Input problem
The input or resource is varied and the output is fixed
Law of demand
The higher the price, the smaller quantity that is demanded. Indirect relationship
Changes in demand
- price of related goods or services (substituted, complements)
- income (normal, inferior, superior goods)
- tastes/trends
- consumer expectations (prices or income)
- number of consumers
Law of supply
As price rises, quantity supplied increases
Direct relationship
Changed in supply
- input/resource prices
- price of related goods or services (substitutes, complements)
- technology
- expectations of future prices
- number of producers
- taxes (decrease supply) or subsidies (increase supply)
Needed for an outward shift of the PPC curve
- more technology
- more research
- better quality of resources
