Final answer:
An improvement in technology and a decrease in the price of inputs will lead to a decrease in the current supply of a good.
Step-by-step explanation:
An improvement in technology that reduces the cost of production will cause an increase in supply. This is because when the cost of production decreases, firms are more motivated to produce output and therefore supply a larger quantity at any given price. This can be shown by a rightward shift in the supply curve.
On the other hand, a decrease in the price of inputs to the production process will also lead to a decrease in the current supply of a good. When input prices decrease, firms have higher profits, so they are more motivated to produce output and supply a larger quantity at any given price. This can also be shown by a rightward shift in the supply curve.
However, a fall in the current price of a good or service and a belief that the price of a good or service will go up in the future do not directly lead to a decrease in the current supply of a good. These factors may affect demand rather than supply.
