Answer:
Institution
Step-by-step explanation:
An economy is a function of how money, means of production and resources (raw materials) are carefully used to facilitate the demands and supply of goods and services to meet the unending needs or requirements of the consumers.
Hence, a region's or country's economy is largely dependent on how resources are being allocated and utilized, how many goods and services are to be produced, what should be produced, for whom they are to be produced for and how much money are to be spent by the consumers to acquire these goods and services.
In this context, the government of a particular country is considered to function as an institution because it is saddled with the responsibility of providing basic human needs and performs certain functions for society. Also, a government being an ongoing organization has a life separate from the lives of the individuals who are part of it and as such it's perpetual or a continuum.
