Final answer:
The shift from S1 to S2 can be explained by various factors such as changes in the goods produced, resource costs, and competition in the market.
Step-by-step explanation:
The shift from S1 to S2 could be explained by several factors including:
The supplier began to produce a more profitable good instead, which would cause them to increase the supply of that good.
Innovative technology causing resource costs to decrease, which would make it cheaper for the supplier to produce the good and lead to an increase in supply.
The cost of a necessary resource in producing the good increased, resulting in higher production costs and a decrease in supply.
Two major competitors going out of business, which would likely increase market share for the remaining suppliers and lead to an increase in supply.
These factors can impact the supply curve and result in a shift from S1 to S2.
