How can the price of baseball bats be affected by the demand for paper or the price of a catchers' mitts be affected by the demand for cheese?

- Higher demand for paper, less wood for bats, the higher price of bats, OR less supply of bats.(have to pay a higher price for wood, and if price doesn't change, they have to make less).

- Higher demand for cheese, cows kept alive, leather is scarce, the higher price of mitts. (less supply because more of the resource is allocated to the milk instead of the leather).

Explanation:

The baseball bats, as well as, paper both, are made employing the resources generated from wood resources. Similarly, the catcher's mitts and cheese are made using the cows as the resource. If two products are made employing similar resources, an increase in the price of one leads to an increase in the other as well. This occurs primarily due to the fact that if the price of the first good increases, the producer of that good is likely to pay more to get the resource and sell the good at a higher price later. Thus, the other producer will either buy less and produce less or spend more to get the resource as per his need.
