Introduction to Globalization:

Globalization is the process that allows goods produced in one country or workers from one country to enter any country in the world without any restrictions. In other words, globalization is essentially the integration of a national economy with the global market.

In today's era, the entire world has become one. All countries in the world are interconnected from economic, political, social, cultural, technological, etc., perspectives.

People from one country go to another country for employment, business, etc. Goods produced in one country are sold in another country without any restrictions.

The main factors contributing to the rapid globalization in today's era are technological advancements, economic liberalization, development in the transportation sector, progress in the communication sector, the World Bank, the World Trade Organization, the International Monetary Fund, regional economic organizations, etc.

Nepal entered globalization with the start of privatization and liberalization from the decade of 2050 BS (1990s). However, Nepal has not been able to take full advantage of it. Nepal needs to increase its competitive capacity to take full advantage of it.

Positive Aspects of Globalization:

Globalization has many positive aspects. The main positive aspects are as follows:

1. Market Expansion: Globalization has made international markets accessible, significantly expanding the market for goods and services. Goods produced in the country can be exported to international markets, earning large amounts of foreign currency. This can increase production, employment, and income in the country, raising the living standards of the people.
2. Foreign Employment and Remittance Income: Globalization has played a significant role in solving the problem of unemployment in underdeveloped countries like Nepal. As of now, more than four million youths from Nepal have found foreign employment. This has resulted in a large inflow of remittance income. Currently, the remittance income received by Nepal is about 28% of the total gross domestic product.
3. Poverty Reduction: Globalization has played a significant role in reducing poverty in many underdeveloped countries like Nepal. In Nepal, in the fiscal year 2051/52 BS (1994/1995 AD), 42% of the population was below the poverty line. By the fiscal year 2082/83 BS (2025/2026 AD), the population below the poverty line had decreased to 21.6%. The main reason for this is that after globalization, Nepal gained access to foreign employment opportunities, and the resulting remittance income was distributed in Nepal.
4. Acquisition of Technology: Underdeveloped countries like Nepal, which were far behind in terms of technological development, have acquired new and high-level technology due to globalization. For example, mobile phones, computers, transportation equipment, etc., are imported from other countries. If globalization had not occurred, it would not have been possible to use these goods.
5. Benefit to International Consumers: Globalization has increased competition among international producers. They are forced to produce high-quality goods at low cost. This has benefited consumers in the international market, who have access to quality goods at reasonable prices.

Negative Aspects of Globalization:

Globalization has not only positive aspects or benefits but also negative aspects or disadvantages. These are as follows:

1. Adverse Impact on Underdeveloped Countries: Underdeveloped countries like Nepal are behind in terms of technology, skills, knowledge, etc. The industries in these countries cannot compete with the industries in developed countries and other industrialized countries. Therefore, the industries in underdeveloped countries, unable to compete, face the possibility of closure. This can lead to the loss of domestic employment.
2. Brain Drain: Brain drain refers to the migration of educated, skilled, and trained citizens of a country to another country in search of better opportunities. Due to globalization, there is a rapid trend of educated, skilled, trained, and capable human resources from underdeveloped countries seeking better opportunities in developed countries like the United States of America, Canada, Australia, Britain, etc. This is a significant loss for the nation.
3. Environmental Degradation: Globalization has led to market expansion, significantly increasing the demand for goods. To meet this expanded demand, large-scale production of goods leads to emissions of smoke, dust, toxic substances, etc., causing environmental degradation.
4. Decrease in Savings and Investment: Due to globalization, cheap and luxurious goods have been imported into poor countries like Nepal. This has led to a decrease in national savings. When national savings decrease, national investment also decreases. The lack of investment can trap poor countries in poverty. Therefore, a situation has been created where poor countries remain poor.
5. Economic Dependence: Due to globalization, no country is forced to produce all goods themselves. Every country produces only those goods that are profitable or can be produced cheaper than others, while importing other goods. This has increased economic dependence among countries worldwide.

Introduction to Economic Liberalization:

Economic liberalization is the process of freeing a country's economy from government control or intervention and encouraging the private sector to participate in economic activities.

In other words, liberalization is the economic policy of giving the authority to decide things like what to produce, how much to price, where to sell, what quality of goods to produce, etc., to the individual or enterprise that is actually producing.

In such an economic policy, the government does not unnecessarily interfere with the private sector. Therefore, entrepreneurs can work independently. This leads to the proper circulation and use of resources, and consumers can obtain good quality goods at reasonable prices.

Economic liberalization started in Nepal from the fiscal year 2048/49 BS (1991/1992 AD). After economic liberalization, private banks, private universities, private hospitals, etc., have come into operation in Nepal. Simultaneously, after adopting the liberalization policy, the Government of Nepal started the process of privatizing public enterprises. 

As of now, 30 public enterprises have been privatized in Nepal.

Positive Aspects of Economic Liberalization: 

Economic liberalization has many positive aspects. These are as follows:

1. High Economic Growth: Economic liberalization encourages the private sector, leading to increased investment. It also attracts direct foreign investment. Increased investment leads to increased national production, resulting in a higher economic growth rate for the country. For example, Nepal achieved a high economic growth rate due to the economic liberalization implemented by the Government of Nepal in 2050 BS (1993 AD). However, later, internal conflict and political instability caused Nepal's economic growth rate to decline.
2. Industrial Development: Under economic liberalization, as the private sector can invest independently, and it also helps attract foreign investment, it contributes to the industrial development of the country.
3. Increase in Employment: Economic liberalization leads to increased investment and rapid industrialization, creating new employment opportunities. This helps in solving the problem of unemployment in the country.
4. Benefit to Consumers: In economic liberalization, competition among producers leads to the production of quality goods at lower prices. Consumers also have the freedom to consume goods according to their preferences. Therefore, economic liberalization benefits consumers.
5. Reduction of Trade Deficit: Economic liberalization plays a significant role in increasing foreign trade. In economic liberalization, there are no restrictions on imports and exports. Therefore, as domestic industries produce goods based on comparative advantage, exports increase, and the country's trade deficit decreases.

Negative Aspects of Economic Liberalization: 

Although economic liberalization has many positive aspects, it also has some negative aspects or disadvantages. 

These are as follows:

1. End of Traditional Technology, Skills, and Knowledge: Economic liberalization creates fierce competition among producers, forcing them to produce quality goods at lower prices using modern technology, skills, and knowledge. This leads to the end of traditional technology, skills, and knowledge.
2. Unhealthy Competition: In economic liberalization, any entrepreneur or producer has to produce quality goods at low cost to survive. This can lead to unhealthy competition among entrepreneurs or producers.
3. Increase in Unemployment: In economic liberalization, modern technology has to be used to compete. This displaces labor, leading to an increase in unemployment in the country.
4. Pollution and Other Environmental Problems: Due to economic liberalization, large industries from wealthy or developed countries are established in underdeveloped countries in search of cheap labor. The smoke, dust, toxic substances, noise, etc., emitted from these large industries cause pollution as well as other environmental problems.
5. Increase in Economic Inequality: Economic liberalization has increased economic inequality. Currently, in the world, the rich are becoming richer, and the poor are becoming poorer. Economic liberalization is one of the reasons for this.

Introduction to Privatization

Privatization is the process of transferring ownership of assets, industries, businesses, etc., that are under government ownership to the ownership of the private sector. 

In other words, privatization is the transfer of ownership of industries, businesses, or government organizations that are under government ownership to the private sector, either partially or fully, or involving the private sector in the management of such organizations. 

Its main objective is to reduce the role of the government and to make the private sector strong and involve it in productive businesses.

Industries established by the government are called public enterprises. In Nepal, before 2007 BS (1950 AD), only two public enterprises were established: Nepal Bank Limited and Raghupati Jute Mills. After the implementation of the First Five-Year Plan in 2013 BS (1956 AD), the establishment and development of public enterprises gained momentum. 

By the end of the Seventh Five-Year Plan (2042-2047 BS, 1985-1990 AD), 65 public enterprises had been established.

Some of the major public enterprises included Bhrikuti Paper Mills, Bansbari Leather and Shoe Factory, Nepal Telecommunications Corporation, Nepal Oil Corporation, Birgunj Sugar Factory, Lumbini Sugar Factory, Nepal Transport Corporation, etc. However, after the political change of 2046 BS (1990 AD), the then government formulated a policy to privatize public enterprises. As of now, 30 public enterprises have been privatized in Nepal.

Positive Aspects of Privatization: 

Privatization is an important economic policy. It plays a significant role in the expansion and development of the economy by making optimal and maximum use of the available resources and means in the country.

The main positive aspects or benefits or importance of privatization can be mentioned as follows:

1. Increase in Competition: Public enterprises receive government subsidies and operate under a monopoly. Therefore, they lack competitive capacity. However, after privatization, such industries or businesses have to compete with other industries or businesses. This forces them to increase production capacity by adopting modern technology and effective management. Consequently, competitive capacity increases, leading to the production of better and cheaper goods.
2. Reduction in Government Intervention: Public enterprises are under the control of the government. Therefore, there is unnecessary government intervention in their operation. Due to government intervention, their work efficiency is negatively affected. Thus, privatization is very important to eliminate unnecessary government intervention.
3. Increase in Revenue: After the sale of loss-making industries under government ownership to the private sector, the government levies various types of taxes on the income and profits earned by them. This increases government income or revenue.
4. Creation of Employment Opportunities: After privatization, as government intervention ends, industries and businesses are operated efficiently. Simultaneously, with the expansion of these industries, the number of other related industries also increases. This creates new employment opportunities.
5. Increase in Consumer Satisfaction: Public enterprises often neglect consumer demand, preferences, taste, choice, etc. However, private industries and businesses produce goods and services according to consumer demand, preferences, taste, choice, etc., which increases consumer satisfaction.

Negative Aspects of Privatization:

The negative aspects or disadvantages of privatization are as follows:

1. Neglect of Public Welfare: The main objective of the private sector is to maximize profit. Therefore, it only produces goods and services that generate high profits. It does not pay attention to the production of essential goods and services for the public, such as education, health, public transport, drinking water, electricity, etc., which have lower profit margins.
2. Unemployment: The private sector always aims to minimize costs and maximize profits. For this, it uses modern technology, which can displace workers and create unemployment.
3. Labor Exploitation: The private sector often pays low salaries or wages to workers and makes them work for longer hours. Thus, there is extensive exploitation of labor in privatization.
4. Increase in Economic Inequality: When industries or national assets under government ownership are privatized, only a few wealthy individuals can afford to buy them. They become owners, while people from poor communities become workers. The income of the owner class increases, making them even wealthier than before, while the working class remains poor, leading to an increase in economic inequality in the country.
5. Neglect of Backward Areas: Since the main objective of the private sector is to maximize profit, it does not want to do business in backward areas where there is less infrastructure and market potential. This hinders the development of backward areas.
6. Misuse of Resources: Instead of producing essential goods, the private sector prioritizes the production of fashionable, luxurious, and convenient goods and services with the aim of maximizing profit. This neglects the needs and interests of the majority of the population and the nation. Therefore, in privatization, resources are misused by producing unnecessary goods and services rather than essential ones.

Cooperatives in Nepal

(a) Development of Cooperatives in Nepal:

In this way, it is found that there was a practice of providing necessary assistance to each other when people were in need and working together collectively.

The development of the cooperative sector in Nepal started after the establishment of the Cooperative Department in 2011 BS (1954 AD). The first cooperative, 'Saving Credit Cooperative Society,' was established in Chitwan district on Chaitra 20, 2013 BS (April 2, 1957 AD). The first Cooperative Act was promulgated in Nepal in 2016 BS (1959 AD).

Until 2046 BS (1989 AD), the cooperative sector could not develop as expected due to the unfavorable political environment. After the restoration of democracy, the Cooperative Act, 2048 (1991 AD) was promulgated based on the internationally recognized values and principles of cooperatives, and the environment was created for the smooth development and expansion of cooperative organizations across the country. The Cooperative Act, 2048 (1991 AD) and the Cooperative Rules, 2049 (1992 AD) are in force for the formation, operation, and regulation of cooperative organizations.

Similarly, the National Cooperative Development Board Act, 2049 (1992 AD) has also been enacted to play a facilitating role in the development of the cooperative sector, including policy support, study and research, promotion, and coordination, and the National Cooperative Development Board has been formed accordingly.

In addition to this, the National Agricultural Policy, 2061 (2004 AD) and the Agricultural Business Promotion Policy, 2063 (2006 AD) have also emphasized the use and development of the cooperative system for the development of the agricultural sector.

(b) Current Situation of Cooperatives in Nepal:

As of now, about 27,000 primary cooperative organizations, 66 district cooperative unions, 157 subject-based district cooperative unions, 16 subject-based central unions, one national cooperative bank with 20 branches, and the National Cooperative Federation as the apex body have been established in the country. More than 3.8 million Nepali citizens are affiliated as members of cooperatives. 

With the participation of women being more than 40% in the membership of cooperatives, the contribution made by cooperatives in women's empowerment is significant.

Cooperative Office:

The Cooperative Department has issued standards to make the operation and management of cooperative organizations effective, and monitoring and regulation are being done on that basis, albeit in a limited manner.

Various programs related to cooperatives have been formulated and implemented with the aim of developing cooperatives as an important means of the country's economic, social, and cultural development by increasing the circulation and investment of capital through cooperatives, and to advance cooperatives with priority in poverty alleviation, employment creation, and rural development.

Problems of Cooperatives in Nepal

Despite many efforts being made in the past for the development of the cooperative sector in Nepal, the expected achievements have not been realized. 

The problems currently seen in the cooperative sector are as follows:

(a) Due to the inability to formulate a national cooperative policy, there is a lack of a clear roadmap for the multi-dimensional development of the cooperative sector.

(b) The current Cooperative Act has not been amended according to the times, so effectiveness could not be brought in the work related to the registration, operation, monitoring, and regulation of cooperative organizations.

(c) The current arrangements for the practice of self-governance are not effective, so good governance could not be ensured in cooperatives.

(d) Due to the lack of clear legal provisions for cooperative organizations and cooperative banks engaged in financial transactions, it has been difficult to make financial transactions through cooperatives organized, safe, and reliable.

(e) The appropriate development of formal cooperative education, training, and organized cooperative information system required for the promotion of cooperatives in the country has not been possible.

(f) There is a lack of policy clarity on the subject of grants, loans, and tax exemptions provided to the cooperative sector. Due to the inability to increase the contribution of cooperatives in productive sectors, an environment conducive to self-employment could not be created, and the process of labor force and talents being wasted could not be stopped.

(g) Due to the lack of sectoral policies and programs, the use of the cooperative system in industries and businesses with comparative advantages has not been possible.

(h) The institutional strengthening of the Cooperative Department, which bears the administrative responsibility for the development and expansion of the cooperative sector, has not been possible.

(i) The various levels of cooperative unions have not been able to play an effective role in promoting the development, management, and operation of the cooperative sector.

Solutions to the Problems of Cooperatives in Nepal

Various types of cooperatives are in operation in Nepal. Despite the important role of cooperatives, various problems exist in this sector. 

For the resolution of the problems of cooperatives, or to make cooperatives effective, the following measures can be adopted:

(a) Developing institutional capacity of cooperatives through education, training, and information, and increasing public awareness related to cooperatives.

(b) Making cooperatives active in all types of businesses based on production and services, including the agricultural sector.

(c) Increasing the access of cooperatives to improve the living standards of women, the poor, marginalized, disabled, landless, and backward groups and communities, as well as ordinary citizens.

(d) Making the cooperative sector effective, competitive, and quality by developing and expanding cooperative-promoted industries and businesses.

(e) Establishing good governance in the cooperative sector through the adoption of effective management techniques and regulations, while practicing the basic values and principles of cooperatives.

(f) Promoting cooperation and collaboration between the government, cooperatives, private sector, and development partners to develop, expand, and promote cooperative industries and businesses.

(g) Formulating long-term plans, developing human resources, constructing necessary organizational structures, and making legal arrangements for the development, expansion, and promotion of cooperatives.

(h) Formulating and implementing standards for the inspection of cooperative unions and organizations.

Difficulties in Measuring National Income

Various difficulties are encountered in the accurate measurement/calculation of national income and its various concepts. Some of these difficulties are related to theoretical concepts, while others are related to practical and statistical aspects. Compared to developed countries, the accurate measurement/calculation of national income or its various concepts is even more difficult in less developed or developing countries.

Here, the major problems encountered in the accurate measurement/calculation of national income and its various concepts, focusing on less developed or developing countries, are presented in a summarized form below:

(a) Non-Monetary Transactions: Not all goods and services produced in a country are bought and sold through the medium of money. Especially in the rural areas of developing countries, where monetization is still incomplete, barter exchange of goods is found. Similarly, the services of housewives running the household are not given a monetary value. However, only monetary transactions and goods and services with monetary value are included in the measurement of national income and its various concepts. Therefore, barter transactions and non-monetary activities create difficulties in the accurate measurement/calculation of national income.

(b) Problem of Double Counting: When measuring/calculating national income and its various concepts, only final goods are included, i.e., intermediate goods are not included because the value of intermediate goods is already included in the value of final goods. Intermediate goods are goods used in the production of final goods. However, it is difficult to distinguish between final goods and intermediate goods because the same good can be a final good or an intermediate good depending on its use. 

For example, sugarcane can be taken. If a consumer buys sugarcane and consumes it, it is a final good. If a sugar factory uses sugarcane for sugar production, then in this situation, sugarcane is an intermediate good. If the full value of both the sugarcane produced by the farmer and the sugar produced by the sugar factory is included when calculating national product or income, there will be double counting of sugarcane because the value of the intermediate good sugarcane is already included in the value of the final good sugar. 

Therefore, when calculating national income and its various concepts, there is a possibility of double or multiple counting of some goods and services. In this situation, the value of national income appears higher than the reality.

(c) Illegal and Unrecorded Activities: Illegal and unrecorded activities include narcotics, gambling, prostitution, smuggling, and tax evasion, etc. Such activities are prohibited according to the laws of the country. Therefore, goods and services produced under such activities, the income earned from them, and the expenditure incurred on them are not included in national income and its other concepts. As a result, the value of national income appears lower than the reality. Therefore, illegal and unrecorded activities are taken as a difficulty in national income measurement.

(d) Inadequate and Unreliable Statistics: For the calculation of national income and its other concepts, adequate and reliable statistics related to the production, income, and expenditure of various sectors are required. However, such statistics are not available in developing countries. For example, in such countries, it is difficult to obtain adequate and accurate statistics related to the costs of agricultural production and the production costs of small and cottage industries.

(e) Illiteracy and Ignorance: In developing countries, some people, due to being illiterate, and some people, even after being educated, neglect the importance of national income calculation and do not keep annual records of their production, income, and expenditure. Similarly, the knowledge and ability of national income calculators also play an important role in the calculation of national income. There may be disagreements among calculators on which items of production, income, and expenditure within and outside the country should be included or excluded, as well as which method to use.

(f) Frequent Changes in Price Levels: The monetary value of goods and services is included in the calculation of national income and its other concepts. Generally, the monetary value of goods and services reflects their market price. When the market price changes frequently, even if the physical quantity of goods and services produced remains the same, the monetary value of the production of goods and services appears different. Therefore, the calculation of national income and its other concepts must be adjusted according to the changes in the market price of goods and services. For this, a Price Index Number is required.

(g) Small-Scale Production, Income, and Expenditure: Production, income, and expenditure occurring on a very small scale or quantity individually are not included in the measurement of national income because their records are not kept. However, when such quantities are added in the aggregate economy, a significant value is obtained. As a result, the value of national income appears lower than the reality. Therefore, production, income, and expenditure occurring on a small scale are taken as a difficulty in national income measurement.

(h) Payment of Wages and Salaries in Kind: The payment of wages and salaries in kind is not included in national income, but goods and services provided as additional benefits along with wages and salaries are included in national income. This discrepancy creates difficulties in the measurement of national income.

(i) Other Difficulties: In addition to the difficulties mentioned above, issues such as the calculation of depreciation funds, the calculation of environmental damage, transactions of resale or second-hand goods, the calculation of the value of self-used resources by owners of factors of production, public services such as general administration, police, and army services, the calculation of transfer income, and the calculation of unexpected capital gains and losses shown in business are also taken as difficulties in national income measurement.

Introduction to National Income

National income is the aggregate economic indicator that measures the activities of an economy. Although the concept of national income began in the seventeenth century, it was only in the 1930s that Nobel laureate Simon Kuznets first developed the process of calculating national income.

The calculation of national income refers to the science of calculating aggregate production, income, and expenditure. This task is mainly done by the government to properly assess the economic progress of the country over a specified period. Economic policies are formulated based on the study of national income. Economic plans are formulated.

The economic structure is analyzed. Inflation and deflation are studied. Grants and aid are distributed, and a comparative study of the living standards of the people is conducted. The government and its related bodies need information on national income. In addition, national income provides a basis for the comparative study of economic activities between different countries.

In the production process, on the one hand, goods and services are produced, and on the other hand, the factors of production—land, labor, capital, and entrepreneur—receive income in the form of rent, wages, interest, and profit, respectively.

Some part of this income is again spent on purchasing those produced goods and services, while the remaining part becomes savings. That savings is again invested in production. Thus, modern economists have shown national income as a flow of production, income, and expenditure.

There is a cyclical flow of production, income, and expenditure in the economy, and overall, national production, national income, and national expenditure become equal.

Therefore, national income is the sum of the income earned by all the factors of production owned by a country, both inside and outside the country, within a certain period.

Various Concepts of National Income

In the modern era, the state of economic development of any country can be known only through the data on national income and its various concepts. The past and present economic conditions of a country can be compared from these data. 

Similarly, the economic conditions of different countries can be compared. Therefore, under the various concepts of national income, the following is a discussion about Gross Domestic Product, Gross National Product, Net National Product, National Income, and Per Capita Income:

Gross Domestic Product (GDP)

Gross Domestic Product is the sum of the monetary value of final/ready goods and services produced within the boundary of a country, generally within a period of one year. 

When calculating Gross Domestic Product, the total quantity of each good and service produced within the country in a period of one year is multiplied by its respective price. Then, the products of the quantity and price of all goods and services are added.

This can be expressed symbolically as follows:

$$GDP\; =\; P₁Q₁\; +\; P₂Q₂+...+$$PnQn

Where:

• $P_1, P_2, ..., P_n$= Prices of goods and services

• $Q_1, Q_2, ..., Q_n$ = Quantities of goods and services

• GDP = Gross Domestic Product

The following should be taken into consideration when calculating Gross Domestic Product:

(a) Only goods and services produced within the boundary of the country are included in Gross Domestic Product.

(b) Only goods and services produced within a specific period, especially one year, are included in Gross Domestic Product. If there are goods that were produced in a certain year but remain unsold, their value is included in the Gross Domestic Product of that year. 

(c) Only final/ready goods and services are taken into account when calculating Gross Domestic Product, i.e., intermediate goods used for the production of final/ready goods are not calculated separately because the value of such goods is already included in the value of the final/ready goods. 

(d) Only the monetary value of goods and services that have a market price, i.e., are bought and sold in the market, is included in Gross Domestic Product. 

(e) Only the monetary value of goods and services produced legally and transparently within the country is included in Gross Domestic Product. 

(f) When calculating Gross Domestic Product, the total quantity of each good/service produced within the country in a period of one year is multiplied by its price, and the resulting values are added.

Methods of Measuring Gross Domestic Product

First of all, after calculating the Gross Domestic Product, it becomes easy to calculate various other concepts of national income, such as Gross National Product, Net National Product, National Income, Per Capita Income, etc., by adjusting the necessary data.

Therefore, the method of calculating/ measuring Gross Domestic Product is discussed here. These methods can also be called methods of calculating/ measuring national income.

There are three such methods. Whatever method is used among these three, the result obtained will be the same. However, which method to use depends on the objective of method selection, available data and resources, the state of development of the country, etc.

Below is a brief discussion about the three methods of calculating/ measuring Gross Domestic Product—Production Method, Income Method, and Expenditure Method:

(a) Production Method: 

Under this method, Gross Domestic Product is calculated from the production side. For this, the economy is divided into various production sectors. The Gross Domestic Product (GDP) is calculated by adding the net value of all goods and services produced by these various sectors within one year. 

To find the net value of production of a specific industry or sector, the value of production purchased by that industry or sector from other industries or sectors is subtracted from the total value of production of that industry or sector. 

This method can be used when production data for a specific year is available. This method helps to compare the contribution of various sectors of the economy to the Gross Domestic Product or national income.

(b) Income Method: 

Under this method, Gross Domestic Product is measured from the distribution side. All the factors of production present within the country—land, capital, labor, and entrepreneur—receive income in the form of rent, interest, wages, and profit, respectively, for contributing to the Gross Domestic Product. 

By adding these factor incomes and then adding the undistributed profits and profit tax of corporations, social security contributions, income from self-employment, and the value of depreciation funds to that sum, the value of Gross Domestic Product is obtained.

(c) Expenditure Method: 

When calculating Gross Domestic Product using this method, the total expenditure or spending on goods and services produced within an economy in one year is added. The total expenditure incurred by all individuals in a country, as well as the government and the foreign sector, on consumer goods and investment goods produced in that country within a period of one year can be added to calculate the Gross Domestic Product or expenditure. 

Therefore, according to the expenditure method, Gross Domestic Product is the sum of consumption expenditure (C), investment expenditure (I), government expenditure (G), and net exports (NX).

Therefore, GDP = C + I + G + NX can be written.

The components of this expenditure method of calculating Gross Domestic Product are discussed below:

1. Consumption Expenditure: This is the expenditure incurred by the household sector on the consumption of durable and non-durable goods and services produced in the current year.
2. Investment Expenditure: Fixed investment by the business sector, investment in housing construction, and inventory investment expenditures fall under this category.
3. Government Expenditure on Goods and Services: Expenditures incurred by the central or local government on goods and services produced in the current year are placed under this category.
4. Net Exports: Goods and services produced domestically in the current year that remain after consumption are exported abroad. The value of exports represents the expenditure incurred by the foreign sector on domestic goods and services. Similarly, goods and services produced abroad are imported into the country. The value of imports represents the expenditure incurred from domestic income on foreign goods and services. The value of net exports is obtained by subtracting the value of total imports from the value of total exports. The value of net exports can be positive, zero, or negative.

Theory of Optimum Population

The theory of optimum population is also called the modern theory of population. The economists who propounded this theory are Cannon, Carr Saunders, Robbins, and Dalton. According to Malthus, any kind of population growth is not good.

However, these economists do not fully agree with Malthus's view. According to them, population growth is not always harmful. Population growth becomes harmful only after reaching a certain stage. 

How much population is suitable for any country depends on the natural resources, technical knowledge, and capital available in that country.

The theory of optimum population divides population into three types as follows:

(a) Optimum Population: Optimum population is the size of the population of any country at which the per capita income of that country is maximum. In other words, optimum population is the size of the population which is neither more nor less than required but just right. If the population of the country is more or less than this, the per capita income of the country decreases. Optimum population depends on the resources available in the country.

(b) Underpopulation: Underpopulation is when an increase in the population of any country also increases the per capita income. In other words, underpopulation is when the population is less than the optimum population. In this situation, the natural resources of the country are not fully utilized.

(c) Overpopulation: Overpopulation is when an increase in the population of any country decreases the per capita income. In other words, overpopulation is when the population is more than the optimum population. In this situation, the natural resources of the country have been fully utilized.

Among these three states of population, the first state is considered suitable because per capita income is maximum in this state. 

This can be clarified from the table and figure below:

Table on Optimum Population

Population (in lakhs)	Per Capita Income (Rs.)	Population Status
50	1000	Underpopulation
100	2000	Underpopulation
150	3000	Underpopulation
200	4000	Optimum Population
250	3000	Overpopulation
300	2000	Overpopulation
350	1000	Overpopulation

In the table above, when the population of a country increases from 50 lakhs to 100 lakhs and 150 lakhs, the per capita income of that country also increases from one thousand to two thousand and from two thousand to three thousand respectively. Thus, the state where per capita income increases with increasing population is the state of underpopulation. 

When the population is 200 lakhs or 2 crores, the per capita income is Rs. 4,000, which is the maximum per capita income. Therefore, this is the state of optimum population. If the population increases beyond this, the per capita income starts to decrease. 

For example, in the table, when the population is 2 crore 50 lakhs, 3 crores, and 3 crore 50 lakhs, the per capita income decreases to Rs. 3,000, Rs. 2,000, and Rs. 1,000 respectively. This state is the state of overpopulation.

According to this above figure, 2 crore population is the optimum population. In this state, per capita income is maximum or Rs. 4,000. When the population is less or more than this, the per capita income is lower, for example, when the population is 150 lakhs, the per capita income is Rs. 3,000. 

Similarly, when the population is 250 lakhs, the per capita income is also Rs. 3,000. Therefore, point D in the figure is the point of optimum population. The state from point A to D is the state of underpopulation, and the state from point D to E is the state of overpopulation.

The size of the optimum population is not always constant. When resources, means, and technology increase, the size of the optimum population also increases, and when there is a decrease in resources, means, and technology, its size also decreases. 

The development of production technology and economic resources increases the size of the optimum population because more population is needed to utilize more resources. This theory makes only economic factors the main basis. 

From an economic point of view, a small population may be the optimum population in any country, but from a political point of view, a larger population may be more suitable.

Criticisms of the Theory of Optimum Population

1. Difficult to Determine Optimum Population
   The theory states that the optimum population is the population size at which per capita income is maximized. However, in reality, it is difficult to accurately determine the exact population level where this occurs. The optimum population is not fixed and changes over time due to technological advancements, economic conditions, and resource availability.

2. Ignores Non-Economic Factors
   The theory mainly focuses on economic factors such as per capita income and resource utilization while ignoring important non-economic factors such as social welfare, political stability, and environmental sustainability. A country may achieve high per capita income but still face issues like unequal wealth distribution and poor living conditions.

3. Assumption of Fixed Resources
   The theory assumes that the natural resources of a country are fixed, which is not always true. Resources can be discovered, developed, or depleted over time. Technological progress can increase resource efficiency, making it possible to sustain a larger population than previously thought.

4. Neglects Population Composition
   The theory considers the total population size but does not account for the age structure, skill level, and productivity of the population. A country with an optimum population in terms of numbers may still struggle economically if it has a high dependency ratio (too many children or elderly people) or a workforce lacking necessary skills.

5. Difficult to Apply in Policy-Making
   Even if a country determines an approximate optimum population, controlling population growth through policies is challenging. Population growth depends on multiple factors, including birth rates, migration, cultural beliefs, and government policies. Implementing policies to achieve the optimum population is complex and may face resistance from society.

Malthus's Population Theory

T.R. Malthus was the first economist to propound the theory of population. He was a clergyman from England.

He systematically propounded the population theory in his book "An Essay on the Principle of Population," published in 1798. The theory propounded by him is known as "Malthus's Population Theory."

In Malthus's words: "By nature, human population increases in a slow arithmetical ratio, while it increases in a rapid geometrical ratio unless stopped by want and vice."

At the time of Malthus, the population was increasing excessively in Britain and the rest of Europe, while agricultural production was declining. This caused people to face complex problems such as famine and epidemics.

This worried Malthus, which led him to study and write about population. In this theory, he studied the relationship between population and food supply and concluded that the population growth rate is higher than the food supply growth rate.

Features of Malthusian Theory of Population

The main elements of Malthus's population theory are as follows:

(a) Population Growth Rate: According to Malthus, if there is no hindrance, the population of any country increases in a geometrical ratio, i.e., the population growth follows the sequence 1:2:4:8:16:32. If the population is not controlled, the population of any country doubles every 25 years.

(b) Food Supply Growth Rate: According to Malthus, the food supply growth rate is slower than the population growth rate. Since the law of diminishing returns applies to agriculture, the food supply increases in an arithmetical ratio, i.e., the food supply growth follows the sequence 1:2:3:4:5:6.

(c) Imbalance between Population and Food Supply: According to Malthus, the population increases at a higher rate than the food supply. If arrangements are not made to stop population growth, the population will increase along with the increase in the means of subsistence, and after a certain time, the population growth will exceed the means of subsistence. Due to this imbalance, people will face many crises, such as famine, epidemics, floods, landslides, etc.

(d) Population Control: Malthus presented a pessimistic view to the world regarding the difficulties arising from this imbalance, saying that it is extremely necessary to control the population.

According to him, population can be controlled in the following two ways:

1. Natural or Positive Checks: Population and food supply are balanced by natural checks. In this method, nature increases the death rate through famine, floods, earthquakes, cholera, plague, etc., to control the population. However, this method is extremely painful.
2. Artificial or Preventive Checks: Natural checks are extremely painful. Therefore, to survive them, people must adopt preventive checks to reduce the population. Preventive checks are those adopted by humans. The purpose of this check is to reduce the birth rate and thus reduce the population. As methods of preventive checks, Malthus advised delaying marriage, practicing celibacy, and living a temperate life. An important point here is that since Malthus was a clergyman and a religious person, he did not say anything about modern methods of family planning in relation to preventive checks.

According to Malthus, if population growth is not stopped by artificial checks, nature will adopt its harsh methods. Therefore, he argued that it is essential for people to adopt artificial checks to avoid the suffering of natural checks.

The Malthusian Trap

The Malthusian Trap is a concept derived from Thomas Robert Malthus’s Theory of Population, which explains how population growth tends to outpace food production, leading to cycles of poverty, famine, and stagnation in economic development.

Malthus, in his book An Essay on the Principle of Population (1798), argued that:

1. Population grows exponentially (1, 2, 4, 8, 16…)

2. Food production grows arithmetically (1, 2, 3, 4, 5…)

Since population increases faster than food supply, there will come a point where food becomes insufficient, leading to crises such as famine, disease, and war, which act as natural checks on population growth.

The Malthusian Trap (Catastrophe)

The Malthusian Trap occurs when:

• Any economic or technological progress leads to higher living standards, which causes higher birth rates and lower death rates.

• This rapid population growth then reduces per capita food availability and resources, eventually pushing people back into poverty and hunger.

• The cycle continues, preventing long-term improvements in living standards.

Example of the Malthusian Trap

In pre-industrial societies, agricultural advancements temporarily improved food supply, but soon, the growing population consumed the extra resources, keeping most people at subsistence-level living.

Criticism and Relevance in today's world

• The Industrial Revolution helped many countries escape the Malthusian Trap by improving technology, increasing agricultural productivity, and lowering birth rates.

• Modern economists argue that human innovation, education, and policy changes can break the cycle predicted by Malthus.

Despite this, concerns about overpopulation, resource depletion, and environmental degradation suggest that some aspects of the Malthusian Trap remain relevant, particularly in developing nations facing food scarcity and economic challenges.

Criticism of Malthus's Population Theory

Modern economists have criticized Malthus's Population Theory as follows:

(a) Groundless Mathematical Formula: According to Malthus, population increases in a geometrical ratio and food supply increases in an arithmetical ratio, and if not controlled, the population of any country doubles in 25 years. However, since there is no example in world history to prove these things, we can call this formula groundless.

(b) One-sided View: According to Malthus, the population of any country depends on its food production. In reality, this view is one-sided and flawed. People in all countries do not depend only on agriculture. They also earn their livelihood from other industries besides agriculture.

(c) Pessimistic Theory: Malthus's Population Theory is pessimistic because it assumes that an increase in population is harmful in all circumstances. However, according to Professor Cannon, a child does not only come with a mouth to feed but also with two hands to work and mental capacity to think about improving production methods.

(d) Based on the Law of Diminishing Returns: Malthus's theory is based on the false assumption that the law of diminishing returns always applies to agriculture. However, as a result of scientific progress in agriculture, the law of increasing returns can also apply due to the use of improved seeds, chemical fertilizers, etc. Thus, this theory is flawed.

(e) Natural Disasters are not Indicators of Overpopulation: According to Malthus, natural disasters, i.e., when earthquakes occur, floods come, famines occur, and diseases like cholera and plague spread, it should be understood that there is overpopulation. However, these natural disasters can occur even when the population is small. Famine and infectious diseases are the result of inefficient production, unequal distribution, and lack of health services, not due to overpopulation.

Microeconomics and Macroeconomics

According to modern economic analysis, the subject matter of economics is mainly divided into two parts: microeconomics and macroeconomics.

These are discussed below:

Microeconomics

The English word 'micro' originates from the Greek word 'mikros'. Its meaning is tiny or small. Therefore, microeconomics can be defined as the branch of economics that studies small or individual economic units or sectors. 

It is also called sukshma arthashastra, meaning 'microeconomics'. Thus, microeconomics studies individual or specific goods and specific resources. It only studies a single market or a single consumer or a single industry. 

Therefore, microeconomics studies small activities or units in the economic world. 

According to Professor Kenneth Ewart Boulding, "Microeconomics is the study of particular households, particular prices, wages, incomes, particular industries, particular commodities." 

The main subject matter of microeconomics is how the price of goods and services is determined in the market. The study of demand and supply affected by these prices are also its main subject matters. Therefore, it is also called 'price theory'. 

According to Professor Schultze, "Price theory is the main tool of microeconomics."

Macroeconomics

The English word 'macro' originates from the Greek word 'makros', which means broad or large. 

Therefore, macroeconomics can be defined as the branch of economics that studies large or aggregate economic units or sectors. It is also called brihat arthashastra, meaning 'macroeconomics'. 

Macroeconomics studies the overall form of the economy. Macroeconomics studies the entire economy or the total and average values related to it. Thus, macroeconomics studies total national income, total savings, total employment, and total consumption, etc. 

Therefore, under macroeconomics, we study the aggregate form of the economy. 

For example, the study of the income of a single family and the production of a single firm falls under microeconomics, while the study of the total income of the nation and the production of the entire industry falls under macroeconomics. 

Professor Kenneth Ewart Boulding defined macroeconomics as follows: "Macroeconomics deals with aggregates of these quantities, not with individual incomes but with national income, not with individual prices but with price levels, not with individual output but with national output." 

Since macroeconomics studies the income, employment, and production of the entire economy, it is also called 'the theory of income, output, and employment'.

Differences Between Microeconomics and Macroeconomics

Although microeconomics and macroeconomics are interrelated, there are some differences between them. These are mentioned below:

(a) The English word 'micro' originates from the Greek word 'mikros'. Its meaning is small. Therefore, microeconomics studies small or individual economic units. On the other hand, the English word 'macro' originates from the Greek word 'makros'. Its meaning is large. Therefore, macroeconomics studies large or aggregate economic variables.

(b) The branch of economics that studies individual economic units is called microeconomics, while the branch of economics that studies the overall economy is called macroeconomics.

(c) The subject matter of microeconomics includes the income of a family, the price of a good, the wage of a worker, the income of a person, the production of a firm or industry, etc., while the subject matter of macroeconomics includes national income, total national production, per capita income, total savings, total employment, and total consumption, etc.

(d) In microeconomics, the study focuses on how the price of a good or resource is determined, hence it is also called the theory of price determination. In macroeconomics, the study focuses on the income, employment, and production of the entire economy, hence it is also called the theory of income and employment. 

For example, the study of the income and expenditure of a family for a year is done in microeconomics, while the study of the income and expenditure of all households in the country is done in macroeconomics.
