The cost paid in money to hire a resource is an explicit cost.

Here's why:

1. An explicit cost involves a direct payment of money to purchase something or hire a resource. It's a clear, out-of-pocket expense.

2. An implicit cost, on the other hand, is a cost that has occurred but is not initially shown or reported as a separate expense. It represents opportunity costs that have been foregone.

3. An alternative-use cost is the cost of forgoing the next best alternative when making a decision. It's a type of opportunity cost.

4. Economic profit takes into account both explicit and implicit costs. It's the difference between total revenue and total cost (including both explicit and implicit costs).

So, when you pay money to hire a resource, you're dealing with an explicit cost.
