 Here we are going to explain the basic economic agents. In the production or the economy what are the basic economic agents? Mostly the economic agents they will be categorized in the form of the two, but broadly they are not the two rather they will be the three. Once though group of the consumers or the individual that consume the commodities they will be the one group and they are the basically named under the title of consumers and they have the capacity that they are going to market for the purchase of the certain goods and from which capacity they are going to purchase they may have certain their endowments with them and that endowment can be in the form of initial stock or the initial endowment and previously these initial endowments were in the form of the land or this initial endowments were in the form of the gold or certain coins that those consumers may have for the purchase of food, for the purchase of cloth, for the purchase of their shelter or any type of the luxury in the nowadays. And here the consumers they have to decide through their selection, through their prioritize and the one motivation that keeps them moving here their motivation will be their utility, their preference and this utility and the preference will be satisfied with the capacity of the income that is earned or the purchasing power parity that is earned by those consumers and that earned through the consumers in the form of the wages, in the form of the interest or in the form of the rent. So, when these consumers they work as a supplier of the labor they become the part of the factors of production and that firms part of the production comes under the theme of the firms. Now, this is our second group where the firms they are again the individuals or they can be the group of the individuals, but they behave here in the form of the producers and these producers they are motivated not by their consumption, their desires to consume rather they have a desire or the motivation to earn something to earn certain profit. So, for this they have to maximize the level of the output in their production possibility frontier or in their production function of their firm. But these firms or these producers when they have to purchase the factors of the production in that factors of production market they again act as a consumer. In fact, if I tell you that the same person who is a marketer or a producer or a business owner is going to buy the resources of the production when he has to purchase the labor, when he has to purchase the energy units, when he has to purchase the chemicals, when he has to purchase the food, we will give it to the name producer but his behavior in the factor market will be exactly the same as in the commodity market of a consumer. Here too, in the commodity market, the price for consumers cannot dictate, rather the price is taken. In the same way, the same producer who is a commodity, if he is responsible and he is paying for the garbage, then he can talk about his cost of production for the value of the garbage. But when he has to buy the food, he has to buy the petrol, he has to buy the bees, so there he will be working as a syrup or as a consumer. So, this is the interplay or the different roles of the individuals that they exhibit in the economy and this is the that phenomena that we say that in the economy, there are the alternative uses of the various resources. Now, because we have already talked about that on one side there will be the individuals, on the other side the production sector, those production sectors and the consumers, they are coming to interact in the form of the markets. Regulations of wealth in certain hands. So, here, if we look at the third major economic agent, like in mixed economy, we cannot negate the government intervention. So, here the government as a third economic agent will be present and it will be as a market regulator. And at the same time, not only regulator, this social structure to develop, physical structure to develop, investment will also be done. Now, in physical infrastructure, if we look at the road, railway, telephone, facilities, all these are all infrastructure, these will be in the form physical infrastructure. And human capital, which is present in the economy, its growth, its development, to polish it, provision of the social structure in which we have school, college, universities, healthcare system, and all these systems, the system of law, the system of judiciary, police for security, if we look at all these systems, then these will be provided by the government. And here, the motive of the government is neither to maximize utility, which is for the consumer, nor to maximize output, which is the motive of the producer. Here, the main motive of the government, for which it will be working, will be its main motive, that what is the interest of the public, how can people be given service? And the overall objective of the economic growth, how can it be attained?
