Final answer:
An increase in the price of skim milk, when it is a complement to cream in production, might lead to increased milk production to meet demand, thereby potentially increasing the supply of cream too. This increase in cream supply could put downward pressure on its price, assuming demand for cream does not change.
Step-by-step explanation:
When skim milk and cream are complements in production, they are produced together from the same process of separating milk. If the price of skim milk increases, this can indicate that there's a higher demand for skim milk or a lower supply.
For producers of milk, an increase in the price of one product, skim milk, can lead to an incentive to produce more milk overall in order to obtain more skim milk. Because cream is a byproduct of the same production process, this might result in an increase in the supply of cream as a side effect of increased skim milk production.
However, it's important to consider that this increase in the supply of cream will not necessarily lead to a change in price for cream unless the demand for cream changes. If demand remains constant and supply increases, this might exert downward pressure on the price of cream, all other factors being equal.
