1. Price of resources (Raw materials, Electricity, Worker wages) (If resources cost more, supply decreases)
2. Government tools (Higher taxes = decrease in supply, Lower taxes = increase in supply, Regulation increase = decrease in supply) (Subsidies and regulation)
3. Technology (New technology make production more efficient, supply goes up, ex: Henry Ford)
4. Competition (More suppliers enter a market, then supply goes up. Ex: Xbox vs PS4)
5. Prices of related goods (Drop in related good price means a rise in supply for higher priced goods. EX: Wheat and Corn)
6. Producer Expectations (Prices will rise in the future, supply goes down now) (Prices will drop in the future, supply no rises)
