Step-by-step explanation:
The three supply shifters discussed in the course notes are:
- Input prices: When the prices of inputs used to produce goods and services increase or decrease, it affects the cost of production and can shift the supply curve.
- Technology: Improvements in technology can increase productivity and lower production costs, leading to an increase in supply.
- Government policies and regulations: Changes in government policies or regulations, such as taxes or subsidies, can impact production costs and alter the supply curve.
