What is the difference between static efficiency and dynamic

What is the difference between static efficiency and dynamic efficiency? Dynamic efficiency is useful for environmental policymaking while static efficiency is not. Dynamic efficiency allows us to evaluate resource allocations across time periods while static efficiency looks at resource allocation where time is not important. Static efficiency and dynamic efficiency are two names for the same thing. Static efficiency is useful for environmental policymaking while dynamic efficiency is not.

Solution

Solution: Dynamic efficiency allows us to evaluate resource allocations across time periods while static efficiency looks at resource allocation where time is not important

Explanation: Static efficiency occurs when resources are allocated effectively at a point in time; and dynamic efficiency is primarily concerned with how to allocate the resources over a period of time.
