Answer:
The correct answer is: reduce; not as highly valued as others.
Explanation:
All the economic systems must provide people with the goods and services that they want and need. But it is also necessary to limit them from getting as much as they wish.
This is because providing as many goods and services as they want may lead to a reduction in efficiency. Economic efficiency is achieved when resources are allocated in such a way that there is no wastage and resources are allocated to most valued use.
If the economic systems do not restrict the production of goods and services as much as they want it may lead to the production of those goods and services that are not as highly valued as others. This will cause wastage of resources, thus reducing the economic efficiency of the system.
