1.1. What is Economics? If we see our day-to-day activities, most of which are related to earning one’s own living and to the manner of satisfying one’s own wants. These human activities, which are generally called economic, are mainly related to production, distribution, consumption and exchange of goods and services. The scientific study of various problems arising out of these economic activities is called economics. 1.2. Basic Economic Problem The basic economic problem is Human wants are many; but means to satisfy these wants are limited. These limited means are capable of alternative uses and hence there is a need of satisfying maximum wants with limited resources. In reality most resources are scarce. Similarly, Individuals and nations possess boundless desires, yet they are constrained by a finite pool of resources, including labor, machinery, factories, and raw materials. These scarce resources can be allocated in multiple ways to fulfill various needs. Likewise, individuals have limited financial means but an array of wants they aspire to satisfy, necessitating careful decision-making regarding resource utilization. For instance, a farmer has the option to cultivate crops such as paddy, sugarcane, banana, or cotton on his garden land. However, the choice of crop must be made based on the availability of irrigation water, as different crops have varying water requirements. More example are shown in figure 1.
Every science has its own language. Economics has its own language. There are certain terms which are used in a special sense in economics. So we must understand the meaning of some basic concepts in the field of economics are discussed below. 2.1. Goods Anything that can satisfies a human want is called a good in economics. For example: Foodgrain, pulse, oilseeds, machinery, seeds, fertilizer, pen, book, etc. 2.2. Services A service refers to an act or performance that one party provides to another. Services are characterized by their intangible, non-material nature, as well as their inseparability, variability, and perishability. Examples include the services offered by doctors, teachers, lawyers, engineers, and laborers.
3.1. Agriculture • The term agriculture originates from the Latin words ager, meaning soil, and cultura, meaning cultivation. • In its broadest sense, agriculture refers to the cultivation of crops and the rearing of livestock for production. • It is essentially synonymous with farming, involving the field-based production of food, fodder, and industrial organic materials. 3.2. Economics • Economics is the science that studies as how people choose to use scare productive resources (like land, labour, capital and organiser) to produce various goods and to distribute these goods to various members of the society for their consumption. 3.3. Agricultural Economics • Agricultural economics is a branch of applied economics that applies the principles of choice to the efficient use of scarce resources such as land, labor, water, seeds, and fertilizers in farming and related activities. • It focuses on guiding farmers in the optimal utilization of land, labor, and capital. • Its significance lies in providing practical solutions to help farmers maximize income while managing limited resources effectively. 3.4. Definitions 1. Prof. Gray has defined agricultural economics as “The science in which the principles and methods of economics are applied to the special conditions of agricultural industry”.
4.1. Introduction The agricultural sector plays a vital role in a nation’s economic development. It has been a key driver of prosperity in advanced economies and remains essential for the progress of developing nations. In regions with low per capita real income, agriculture and other primary industries are given high priority. As Dr. Bright Singh emphasizes, “An increase in agricultural production, along with a rise in the per capita income of the rural population, fosters industrialization and urbanization, thereby boosting demand for industrial goods.” The historical trajectory of England provides clear evidence that the Agricultural Revolution preceded and laid the foundation for the Industrial Revolution. Similarly, in the United States and Japan, agricultural advancement has played a pivotal role in fostering industrialization. Many developing nations, in their pursuit of economic growth, have recognized the limitations of an excessive focus on industrialization as a sole strategy for achieving higher per capita real income. Industrial and agricultural development are not substitutes but rather complementary forces that mutually reinforce each other in terms of both inputs and outputs. Empirical observations indicate that enhanced agricultural productivity and output significantly contribute to a nation’s overall economic progress. Therefore, prioritizing the further development of the agricultural sector is both rational and essential.
5.1. Meaning Demand in economics means a desire to possess a good supported by willingness and ability to pay for it. If you have a desire to buy a tractor, but do not have the adequate means to pay for it, it will simply be a wish, a desire or a want and not demand. Demand is an effective desire, i.e., a desire which is backed by willingness and ability to pay for a commodity in order to obtain it. In the words, “Demand means the various quantities of a good that consumer willing and able to purchase at various price during a particular period of time in a given place/market”. Thus, demand in economics implies both the desire to purchase and the ability to pay for a good. 5.2. Definitions 1. According to Prof. J M Keynes, “emphasized the importance of effective demand, which is the total amount of goods and services that consumers are willing and able to purchase at various price levels, taking into account their income and other factors”. 2. According to Alfred Marshall, “the amount demanded of a commodity is the amount that buyers are able and willing to purchase at a given price in a given time period.” 3. According to John Maynard Keynes: “demand as the total amount of goods and services that individuals, businesses and the government are willing and able to purchase at various price levels”. 4. According to Milton Friedman “demand as the quantity of a good or service that people are willing to buy at a specific price, influenced by their utility and income”. 5. According to Paul Samuelson “demand as the quantity of a product that consumers are willing to buy at different prices, holding other factors constant”.
6.1. Concept of Utility In the ordinary language, ‘utility’ means ‘usefulness’. In Economics, utility is defined as the power of a commodity or a service to satisfy a human want. Utility is a subjective or psychological concept. The same commodity or service gives different utilities to different people. For a vegetarian, mutton has no utility. Warm clothes have little utility for the people in hot countries. So utility is determined by the consumer and his need for the commodity. Total Utility Total Utility is denoted by the sum of utilities of all units of a commodity consumed. For example, if a consumer consumes ten biscuits, then the total utility is the sum of satisfaction of consuming all the ten biscuits. Marginal Utility Marginal Utility is the addition made to the total utility by consuming one more unit of a commodity. For example, if a consumer consumes 10 biscuits, the marginal utility of 10th unit is nothing but the total utility of 10 biscuits minus the total utility of 9 biscuits. 6.2. Law Of Diminishing Marginal Utility The law of diminishing marginal utility explains an ordinary experience of a consumer. If a consumer takes more units of a commodity, the additional utility he derives from an extra unit of the commodity goes on falling. Thus, according to this law, the marginal utility decreases with the increase in the consumption of a commodity. When marginal utility decreases, the total utility increases at a diminishing rate.
7.1. Introduction The concept of consumer’s surplus was first introduced by Alfred Marshall. When a consumer plans to buy a commodity, they assess the utility they will gain from its consumption. A rational consumer always compares the utility derived from a good with the price they must pay for it. If the utility exceeds the price, the consumer chooses to buy it; otherwise, they do not. The excess utility gained over the price paid is known as consumer’s surplus. In nutshell, Consumer’s surplus is the difference between the amount a consumer is willing to pay for a good and the amount they actually pay. Consumer’s surplus = Price that a consumer is willing to pay - Price he actual pays Suppose a consumer wants to buy a shirt and is willing to pay `250 for it, but the actual price is only `200. In this case, the consumer gains a surplus of `50. This difference, known as consumer’s surplus, represents the extra benefit the consumer receives from the purchase. Consumer’s surplus is often experienced with commodities that are highly useful but relatively inexpensive, such as newspapers, salt, matchboxes, and postage stamps. In these cases, consumers are willing to pay more than the actual price, resulting in a surplus of utility
8.1. Meaning The Law of Demand states that when the price of a good increases, its quantity demanded decreases, assuming all other factors remain constant. However, the law does not specify how much the quantity demanded will decrease in response to a price increase or how sensitive demand is to price changes. This information is crucial for businesses and policymakers. To address this, Alfred Marshall developed the concept of elasticity of demand, which measures the responsiveness of quantity demanded to changes in factors such as price, income, and the price of related goods. 8.2. Type of Elasticity of Demand There are three types of elasticity of demand viz., 01) Price Elasticity of Demand 02) Income Elasticity of Demand 03) Cross elasticity of Demand 1. Price elasticity of Demand Price elasticity measures the responsiveness of the quantity demanded of a commodity to changes in its price, while keeping all other factors constant (ceteris paribus).
9.1. Production Production means creation of value in the goods, i. e. creation of utility. Production activity helps in transforming a set of inputs into goods and services. It essentially means transforming of one set of goods into another. The output generated from production possesses greater utility than the combined inputs used in the production process. The inputs that are utilized in production of goods may be provided by the nature and/ or by other industries. 9.2. Factors of Production These mean the production resources required to produce a given product. Fraser defined factor of production as “a group or class of original productive resources”. The factors of production have been traditionally classified as land, labour, capital and organization. Land According to Marshall, land means “the materials and forces which nature gives freely for man’s aid, in land and water, in air and light and heat.” In Economics the term land has a very broad meaning. It includes all free gifts of nature available to mankind viz., air, water and land. It includes all types of land surfaces such as mountains, valley, plains, forests etc. It includes all types of water resources such as rivers, oceans, etc. Thus the concept of land includes all natural resources on, above and below the earth’s surface.
10.1. Introduction In the production process, the farmers combine the required input factor in various proportion. This type of usage of input by the farmer gives way for the operation of law of returns. In the production process, when the single input factor is varied keeping other required factor constant, the relationship take place between single variable input and the consequent output pertain to either one or a combination of the following relationship. 1. Law of increasing returns; 2. Law of constant returns; and 3. Law of decreasing returns. 10.1.1. Law of increasing returns According to the law of increasing returns, each additional (or marginal) unit of input leads to a proportionally larger increase in output compared to the previous unit. In other words, the productivity of inputs rises as more units are employed.
11.1. Introduction The input-output relationship is commonly referred to as the Classical Production Function. The Classical Production Function is also known as the Law of Diminishing Returns or the Law of Increasing Costs. It is sometimes termed the “Law of Life”, as it serves as a fundamental principle of economics upon which several other economic laws are based. This law analyzes the relationship between a single variable factor and output while keeping all other factors constant. It represents a short-run production function. 11.2. Definition The Law of Increasing Cost states that the proportion of one factor in a combination of factors increases till a certain point but after that first the marginal product then the average product will diminish. According to Marshall “An increase in capital and labour applied in the cultivation of land causes in general less than proportionate increase in the amount of produce raised, unless it happens to coincide with the improvements in the arts of agriculture”. According to Earl O. Heady “If the quantity of one of productive service is increased by equal increments, with the quantity of other resource services held constant, the increments to total product may increase at first but will decrease after certain point”.
12.1. Meaning The rate at which output change as the quantity of all input are change. It is based on long run law in which all factor are variable and factor proportion do not change. Stage of Return to Scale 1. Constant return to scale 2. Increasing return to scale 3. Decreasing return to scale 1. Constant return to scale • In constant return, Change in proportion of input is equal to the change in proportion of output. • A constant return to scale is also known as linear homogenous production function of the first degree. • Example: Industry.
13.1. Introduction Knowledge regarding various relationships existing between costs and output is necessary to comprehend the concepts of equilibrium conditions of different firms under different market conditions. Basically we require data on output, fixed costs, variable costs and the prices of inputs and outputs. From this data we finally derive all the seven cost concepts, viz.,TFC, TVC, TC, AFC, AVC, AC and MC. These cost concepts would have implications for output expansion of the firms and equilibrium position of the firms in different time periods. In the cost theory, economists use different names for cost concepts under different context. They are money costs or nominal costs, real costs, opportunity costs, economic costs, implicit costs, explicit costs, deflated costs, social costs, short run costs, long run costs, separable costs, etc. Nominal Costs or Money Costs These are usually expressed in money terms at current prices. Nominal costs of production refer to per unit cost of production of output at current market prices. Real Costs When the costs of inputs and input services are expressed at constant prices they become real costs.
14.1. Meaning Supply in agriculture refers to the availability of agricultural products, both raw and processed, for distribution to markets, consumers, or other industries. This includes crops, livestock, dairy products, fruits, vegetables, and other agricultural goods. “Supply is the amount of a commodity that sellers are able and willing to offer for sale at different price per unit of time”. In the words of Meyer “Supply is a schedule of the amount of a good that would be offered for sale at all possible price at any period of time; e.g., a day, a week, and so on”. 14.2. Stock Stock in agriculture refers to the quantity of inputs and resources available for farming, such as seeds, fertilizers, pesticides, machinery, and livestock. It encompasses all the assets and materials that a farmer or agricultural operation has on hand to support the production process. “Stock is meant the total quantity of a commodity this exists in a market and can be offered for sale at a short notice”. 14.3. Stocks Vs Supply • Supply may be defined as the active stock (actual quantity) which is made available for the consumers at the prevailing market prices. • Supply is flow concept. • Stock is the quantity of different commodities which are stored; they are made available to the consumer when there are favourable prices.
15.1. Meaning While doing production of goods, the producer coordinates different factors of production i.e., land, labour, capital and management. In the process of distribution the returns obtained through the production activity are apportioned to these factors that are employed in the production process. Consequently land gets rent, labour gets wages and interest is paid to capital and finally organization is rewarded with profit. Such an apportionment of returns among different factors of production is called distribution. It is also called factor pricing. 15.1.2. Rent Rent is the return for the fertility status of the land. In fact the land is defined in a broad sense. All the natural resources existing on the surface and beneath the surface of land like mines, rivers, etc., are also treated as land, from which rent is received. Some resources are publicly owned, while others are privately owned. Rent is almost zero for publicly owned resource because one cannot use it for one’s own purpose. These are meant for public welfare. Rent is expressed in two forms i.e., one is economic rent and the other is contract rent. 15.1.3. Economic Rent Economic rent is the rent received exclusively from the use of land only. We use the term, exclusively because the rent of a building referred as the return obtained by the owner on the capital invested in the construction of building as well as the land. It is the return obtained from the combined values of both. In that case, it no longer qualifies as rent. In farming the rent paid by a tenant to the landlord is not economic rent.
16.1. Meaning National Income is nothing but the aggregate money value of all goods and services produced in a country in a year. It can also be viewed as income distributed among the factors of production in the form of rent (to land), wages (to labour) interest (to capital) and profits (to entrepreneurs). According to Alfred Marshal National Income is defined as the labour and capital of a country acting on its natural resources produce annually a certain net aggregate of goods and services. 16.1.1. Limitations • In an economy in which numerous goods and services are produced, it is really a difficult proposition to estimate them correctly to arrive at the national income. Coming to the farming, farmers do retain some part of production for personal consumption and the rest is only marketed. In such a case, the methodology to evaluate the amount of produce not reached the market has not been given. • Double counting: It implies the same good being counted twice: say, cotton may be counted in agricultural production and the cotton cloth in industrial production. Marshall approached national income from production end. On the other hand, some other economist approached from consumption end. At the same time this approach in reality poses problems. Consumers who number in millions, consumes the same good at different places, and the estimation of their total consumption is a difficult proposition. Hence, there are problems in measurement of national income.
17.1. Theories of Population The theory of population is studied because the supply of labour depends upon population and its growth. Observing the abnormal growth of population and consequent fall in the standard of living, Thomas Malthus (1760 – 1834) an English Clergyman first studied population growth in various countries of Europe. Later he wrote a book entitled “An Essay on the Principles of Population” in 1798. His observations compelled him to foresee a gloomy future for the human race and hence emphasized the immediate need to keep the population growth under check. Now his theory is popularly known as Malthusian theory of population. To quote the theory in his own words “By nature human food increases in a slow arithmetic ratio, man himself increases in a quick geometric ratio unless want and vice stop him.” 17.1.2. Propositions of Malthusian Theory These are briefly presented below: 1. Population is necessarily limited by means of subsistence (food supply). According to Malthus in a country the size of population depends on its food production. Greater the food production, larger would be the size of population, which a country can support and smaller the food production then the country would be in a position to support smaller population only. 2. The power of population is infinitely greater than the power in the earth to produce subsistence for men. He further adds that population growth always overtakes food production, since agricultural production is constrained by the law of diminishing returns. This prevents the food production to grow as faster as that of population. As such, there is no limit to the growth of population. 3. Population increases in geometric progression, whereas food production increases in arithmetic progression. This means that population tends to grow in quick geometric progression i.e., 1, 2, 4, 8, 16, 32, etc., while,
18.1. Meaning When the human civilization was not developed, people used to exchange those goods which they produced for those which others produced. Such an act of exchanging goods for goods is called barter. But as the years rolled by and when the social organization became more complex, barter system was found to be not practicable. The following are the main difficulties which were found in the barter system. 1. Double coincidence of wants 2. Lack of a standard unit of account 3. Impossibility of subdivision of goods 4. Lack of information 5. Production of large and very costly goods not feasible The difficulties in barter system were replaced with the introduction of money. Money has been defined as the medium of exchange. According to Robertson money is defined as “Anything which is widely acceptable in discharge of obligations”. The different stages in the development of money are as follows. 1. Commodity Money: The earliest form of money consisted of goods like rice, wheat, cattle, skins, elephant tusks etc. These were accepted as they were all desired by all the people. 2. Metallic Money: As the civilization advanced, people found it difficult to carry on the exchange transaction with commodities, as they were found to be very inconvenient. Commodity money gave way for the metals to be used as money. These metals include gold, silver, copper, bronze, etc. From the beginning of their introduction, Government kept the right to issue coins and certify their weight and quality. Metals were converted into coins for this purpose.
An economy is a human-made system developed or adapted to fulfill societal needs. There are three main types of economic systems namely mixed economy, capitalist economy, and socialist economy. The following are some key features of an economy: • The type of an economy is determined by the ownership of resources and the means of production. • Resources or means of production may be privately owned, allowing individuals the freedom to use them for profit, or they may be collectively owned and controlled by the government for the overall welfare of society. • The three types of economic systems are classified based on the extent of individual freedom and the role of profit motive in each. 19.1. Capitalist Economy The capitalist, or free-market, economy is the most traditional form, where government involvement in economic activities is minimal. Main features of a capitalist economy 1. Private property: In a capitalist economy, individuals have the right to own property, acquire assets, and utilize them for personal gain. There are no limitations on owning land, machinery, mines, or factories for profit and wealth accumulation. 2. Freedom of enterprise: Individuals have the freedom to choose any occupation they wish to pursue. The concept of free enterprise means that businesses are free to acquire resources and utilize them to produce any goods or services. Additionally, firms have the liberty to sell their products in any market of their choice, while workers have the right to select their employer.
20.1. Introduction • The exchange of goods and services (trade) among countries across national boundaries is called as international trade. • No Country can be self-sufficient in producing all the goods and services required by it. • Thus, Countries need to trade to obtain commodities, they cannot produce themselves or they can purchase elsewhere at a lower price. • The act of selling domestically produced goods to international consumer is known as exportation. India Export Refined Petroleum, Jewellery, Rice, etc. • The act of purchasing goods from foreigne country in order to sell them domestically is known as importation. India import Crude oil, Coal, Gold, Electronics item etc. 20.2. Why International Trade? • Countries cannot domestically produced all the goods and services that each individual consumer wants and needs. • Because each country has different factor of production (Land, Labour, and Capital). • Each country is endowed with different combination of these factors and therefore each country is capable of producing different combination of goods and services. • When domestic production is greater than domestic demand for a good, excess production is traded on the international market
21.1. Meaning Balance of payments is an accounting statement that provide a systematic record to all the economic transaction, between resident of a country and the rest of the world, in a specific time frame. 21.2. Economic Transaction 1. Visible Items: These include all types of physical goods which are imported and exported as they are made of some matter that can be seen, touched, measured. 2. Invisible Items: Invisible items of trade refers to all types of services like shipping , banking , etc…these are called invisible goods as they can’t be felt , seen ,and measured 3. Unilateral Items or transfer: Unilateral transfer include gifts, remittance,etc.. since these transaction donot involve any claims for repayments. 4. Capital transfer: Capital transfer relate to capital receipts (through borrowings or sale of assets)and capital payments (through capital repayments or purchase of assets)
22.1. Meaning GST is a tax imposed on the purchase of goods and services. It is designed to be a single, comprehensive tax that replaces multiple smaller indirect taxes on consumption, such as service tax. • The taxes are included in the final price and are to be paid by the consumers at point of sale and passed on to the government by the seller. • The GST is a common tax used by the majority of countries globally. • It is a unified tax applied to the supply of goods and services from the manufacturer to the final consumers. • More than 160 developed countries implement this system of taxation. • The GST is usually taxed at a single rate across the nation. 22.2. Main Features of Goods and Services Tax (GST) The main features of Goods and Services Tax are as follows: • Dual GST- India has implemented a dual GST system, consisting of two components: Central GST (CGST) and State GST (SGST). The central government collects CGST, while states and union territories collect SGST/UTGST on all supply transactions of goods and services. Following the 101st Constitutional Amendment, both the central government and union territories have the authority to levy taxes simultaneously on the supply of goods and services. • Applicable on supply side- GST is applicable on “supply” of goods or services as against the old concept on the manufacturer of goods or on sale of goods or on provision of services. • Destination based taxation- GST is based on the principle of destination-based consumption taxation as against the present principle of origin-based taxation.
