What is macroeconomic theory?
Macroeconomic theory is a set of views about the way the economy works at the aggregate level. It tries to explain how different factors such as consumption, investment, government spending, taxation, money supply, interest rates, exchange rates, and international trade affect the level and growth of national income, output, employment, prices, and balance of payments. Macroeconomic theory also tries to understand how economic agents such as households, firms, banks, and governments make decisions and interact with each other in various markets.
Macroeconomic theory can be divided into two main branches: classical macroeconomics and Keynesian macroeconomics. Classical macroeconomics is based on the assumptions that markets are perfectly competitive, prices are flexible, expectations are rational, and output is determined by supply-side factors such as technology and capital stock. Classical macroeconomics argues that the economy tends to operate at full employment and potential output in the long run, and that any deviations from this equilibrium are temporary and self-correcting. Classical macroeconomics also advocates for a limited role of government intervention in the economy.
Keynesian macroeconomics is based on the assumptions that markets are imperfectly competitive, prices are sticky, expectations are adaptive, and output is determined by demand-side factors such as consumption, investment, and government spending. Keynesian macroeconomics argues that the economy can experience persistent and involuntary unemployment and output gaps in the short run, and that these problems can be solved by active fiscal and monetary policies. Keynesian macroeconomics also emphasizes the importance of aggregate demand management and stabilization policies.

Chapter-wise summary of the book
Chapter 1: National Income and Economic Welfare
Definition and measurement of national income
National income is defined as the total value of all final goods and services produced in an economy during a given period of time, usually a year. It can be measured by three methods: product method, income method, and expenditure method. The product method measures national income by adding up the value added by all producing units in an economy. The income method measures national income by adding up the incomes received by all factors of production in an economy. The expenditure method measures national income by adding up the expenditures made by all sectors in an economy.
Concepts of economic welfare and social welfare function
Economic welfare is defined as the level of well-being or satisfaction derived from the consumption of goods and services in an economy. It can be measured by various indicators, such as gross domestic product (GDP), gross national product (GNP), net national product (NNP), personal income (PI), Limitations of national income as a measure of welfare
National income, however measured, has some limitations as a measure of economic welfare. Some of these limitations are:
National income does not account for the distribution of income among different groups and individuals in an economy. A high national income may be accompanied by a high degree of inequality and poverty.
National income does not account for the non-market activities that contribute to welfare, such as household work, leisure, volunteer work, and environmental services.
National income does not account for the quality and variety of goods and services produced and consumed in an economy. A higher quantity of output may not necessarily imply a higher quality of life.
National income does not account for the externalities or spillover effects that arise from production and consumption activities, such as pollution, congestion, noise, and health hazards.
National income does not account for the depreciation or depletion of natural and human capital that may result from production and consumption activities, such as soil erosion, deforestation, resource exhaustion, and human capital loss.
Therefore, national income should be adjusted for these factors to obtain a more accurate measure of economic welfare. Some of the alternative measures of economic welfare are:
Green GDP or environmentally adjusted GDP, which subtracts the environmental costs from GDP.
Genuine progress indicator (GPI) or sustainable net benefit index (SNBI), which adds the value of non-market activities and subtracts the costs of inequality, crime, pollution, and resource depletion from GDP.
Human development index (HDI) or quality of life index (QLI), which combines GDP per capita with indicators of health, education, and life expectancy.
Gross national happiness (GNH) or happiness index (HI), which measures the subjective well-being or happiness of people based on various dimensions such as psychological well-being, health, education, culture, governance, ecology, and living standards.
Chapter 2: National Income Accounting and Circular Flow of Income
Methods of national income accounting
National income accounting is a system of recording and measuring the economic transactions that take place in an economy during a given period of time. It provides a comprehensive and consistent framework for estimating national income and its components by using various accounts and identities. The main methods of national income accounting are:
The product method or value added method, which measures national income by adding up the value added by all producing units in an economy. Value added is defined as the difference between the value of output and the value of intermediate inputs used in production. The product method uses the following identity: GDP = GVA + taxes on products - subsidies on products, where GVA is gross value added.
The income method or factor cost method, which measures national income by adding up the incomes received by all factors of production in an economy. Factor incomes include wages and salaries, profits and dividends, interest and rent. The income method uses the following identity: GDP = GNI + net primary income from abroad - consumption of fixed capital - net taxes on production and imports + statistical discrepancy, where GNI is gross national income.
investment by firms, government spending, and net exports by the foreign sector. The expenditure method uses the following identity: GDP = C + I + G + (X - M), where C is consumption, I is investment, G is government spending, X is exports, and M is imports.
All these methods should yield the same estimate of national income, as long as there are no errors or omissions in the data. However, in practice, there may be some discrepancies due to differences in sources, methods, definitions, and coverage of the data. Therefore, a statistical discrepancy term is added or subtracted to balance the accounts.
Circular flow of income in a closed and open economy
The circular flow of income is a simplified model that shows how income flows between different sectors and agents in an economy. It illustrates the interdependence and interrelation of production, income, and expenditure in an economy. There are two types of circular flow models: closed economy and open economy.
A closed economy is an economy that does not have any trade or financial transactions with the rest of the world. It has only two sectors: households and firms. Households supply factors of production (labor, capital, land, and entrepreneurship) to firms and receive factor incomes (wages, profits, interest, and rent) in return. Firms produce goods and services and sell them to households and receive revenues in return. Households spend their incomes on goods and services and save the rest. Firms use their revenues to pay for factors of production and invest the rest. The circular flow of income in a closed economy can be shown as follows:
An open economy is an economy that has trade and financial transactions with the rest of the world. It has four sectors: households, firms, government, and foreign sector. Households supply factors of production to firms and receive factor incomes in return. Firms produce goods and services and sell them to households, government, and foreign sector and receive revenues in return. Households spend their incomes on goods and services from domestic and foreign markets and save the rest. Firms use their revenues to pay for factors of production from domestic and foreign markets and invest the rest. Government collects taxes from households and firms and spends them on public goods and services from domestic and foreign markets. Foreign sector buys goods and
