Final answer:
When producers do not have to pay the full cost of producing a product, they tend to increase production.
Step-by-step explanation:
When producers do not have to pay the full cost of producing a product, they tend to increase production. This is because when costs are lower, producers can make higher profits by producing more units of the product. For example, if a new technology reduces the cost of production, producers can produce more units and still make a profit.
