What are 3 factors that cause a change in supply?

-The price of the production increase: If the price of materials (includes labor, raw materials, and energy costs) needed to produce a given good increase, it will be more expensive to produce the good. Thus, less units of the good will be able to be produced at a given price level.

-Changes in technology: If new, more efficient technology is developed, a good may be able to be produced at a lower cost per unit.

-Change in government taxes of subsidies: If the government imposes a tax on a given good, the firm will be able to sell less at a given price. If the government imposes a subsidy, the opposite is true.
