Features of Macroeconomics: 

a) Study of aggregates - It is a branch of economics that studies the economic variables of an economy as a whole. It focuses on aggregate measures such as aggregate demand, aggregate supply and aggregate price level. 

b) Lumping method - Macroeconomics uses the lumping method. That is, it splits up the entire economy into big lumps (sectors) and then studies aggregate measures such as aggregate demand, aggregate supply and aggregate price level. 

c) General equilibrium analysis - Macroeconomic analysis is based on general equilibrium analysis; that is, it studies equilibrium in different markets simultaneously. This approach assumes “everything depends on everything else”. 

d) Income analysis - Macroeconomics is also known as income analysis because it studies how income and employment levels are determined. It also studies the causes behind fluctuations in these levels. 

e) Policy-oriented - Macroeconomic analysis helps in formulating policies. These policies help in creating new employment opportunities. Also, they pull the economy out of the low level of income and demand. 

f) Interdependence among variables- Macroeconomics takes into consideration the interdependence among the various economic variables. In other words, it explains how changes in one variable influence the change in other.

Macroeconomics studies how an economy operates as a whole. It focuses on aggregate measures such as aggregate demand, aggregate supply and aggregate price level. It studies how these variables are determined and how they change over time. It helps us in understanding various economic relationships and economic problems at the economic or aggregate level. It is also known as the ‘Theory of Income and Employment’, as it studies how income and employment levels are determined. It also deals with major problems such as poverty, unemployment, inflation, balance of payments and BOP disequilibrium. 

The following are the important macroeconomic theories:

i. Theory of income and employment: Macroeconomics explains the determination of national income and employment. In addition it also helps in analysing the cause and effect of fluctuations in them. For this, various concepts such as consumption function, investment function, business cycles are studied. 

ii. Theory of general price level and inflation: Macroeconomics studies how the general level prices in an economy are determined and the effects of fluctuations on them. Such study is specifically important to understand and combat the effect of such problems as depression and recession. 

iii. Theory of economic growth and development: Macroeconomic study helps in understanding the causes of underdevelopment and other socioeconomic problems such as poverty and inequality in an economy. Accordingly, it helps in determining suitable policies to combat the same. Similarly, it helps to deals with such problems as underutilisation of resources, thereby, help in working towards increasing the productive efficiency in the economy.

iv. Macro theory of distribution: The study of macroeconomics helps in determining how the national income would be distributed among the various sections in the economy in the form of rent, wages, income and profit. Some of the important theories in this regard are given by Ricardo, Karl Marx, Kalecki, Kaldor.

Macroeconomics is a branch of economics that studies aggregates covering the entire economy. It studies total employment, national income, national output, aggregate demand, aggregate supply, aggregate consumption and savings and total investment. 

It studies the entire economy in the context of equilibrium. It studies the behaviour of a number of economic variables at a time and takes into consideration their functional relationship and interdependence. Thus, it can be concluded that macroeconomics deals with the economy as a whole.

Macroeconomics is concerned with large sections of the economy or the economy as a whole. It is a branch of economics that studies economics activities of various economic spheres and analyses economic situations and economic problems of the economy as a whole. Microeconomics, on the other hand, studies only one consumer or one producer. In other words, while microeconomics studies individual economic units, on the other hand, macroeconomics studies aggregates. Accordingly, microeconomics is based on partial equilibrium analysis, on the other hand, macroeconomics is based on general equilibrium analysis. In this regard, it can be said that macroeconomics has a wider scope than microeconomics.

Macroeconomics is said to have a wide scope as it deals with aggregates for the economy as a whole. Some of the aggregates that are studied in macroeconomics are national income, general price level, employment, investment, etc. Macroeconomics aims at studying the interrelationship between such aggregates and accordingly determine the cause and effect of variations in them. Thus, it can be said that it studies the various economic units in aggregate terms.

General equilibrium is a method to study equilibrium in different markets simultaneously. It is the method of studying macroeconomics. According to Stigler, the theory of general equilibrium is the theory of inter-relationship of all units of the economy. Hence, this method assumes that all macroeconomic variables are interdependent.

Macro variables are the aggregate quantities that change from time to time. The major macroeconomic variables are aggregate price, aggregate demand, aggregate supply, inflation and unemployment.

Macroeconomics is concerned with large sections of the economy or the economy as a whole. It is a branch of economics that deals with various economic activities, economic situations and economic problems of the economy as a whole.

True 

Explanation: 

The above statement is correct. This is because national output is an aggregate of all outputs produced within an economy during a year. Hence, it is a macroeconomic variable.

Macroeconomics does not study product pricing. 

Explanation: 

Macroeconomics studies an economy as a whole. It focuses on aggregate measures such as aggregate demand, aggregate supply and aggregate price level. As product pricing is an individual variable, it is not studied under macroeconomics. It is studied under microeconomics.

Macroeconomics studies the problem of inflation in an economy.

Explanation: 

Macroeconomics studies how the prices of goods and services in an economy are determined and what causes the change in the price level. Thus, problems concerning the price level constitute the subject matter of macroeconomics.

The credit of development of macroeconomic approach must go to Lord Keynes.

Explanation: 

The need for a separate branch of economics, i.e., macroeconomics was felt inevitable during the period of The Great Depression (1929). It was then when Lord John Maynard Keynes, for the first time, used the macro approach in his book “General Theory of Employment, Interest and Money”.

Growth theory is the subject matter of Macroeconomics.

Explanation: 

Accelerating growth and development constitute the subject matter of macroeconomics. Macroeconomics analyses the reason for underdevelopment and poverty in a country. It also analyses how efficient utilisation of resources can be done. Thus, studying the problems related to growth and improving the per capita income and national income are major concerns of macroeconomics.

True 

Explanation: 

Yes. Macroeconomics adopts the lumping method. It splits the entire economy into big lumps; that is, it divides the economy into aggregates for study. It studies how an economy operates as a whole. It focuses on aggregate measures such as aggregate demand, aggregate supply and aggregate price level and studies how these variables are determined and how they change over time.

Explanation: 

1- Microeconomics uses the method of partial equilibrium. According to the method, equilibrium is achieved in one market assuming that there is no change in the other markets. For example, while analysing the equilibrium of an individual producer (optimising his/her cost of production), we assume that there exists no change in the other markets (labour and capital markets). 

2- Macroeconomics uses the method of general equilibrium, as it studies the equilibrium in different markets simultaneously. It studies the interrelationship of all units of the economy and assumes that all the macroeconomic variables are interdependent. 

3- The theory of growth was jointly propounded by economists Harrod and Domar. This theory helps us in understanding the causes of underdevelopment and accordingly what strategies can be adopted to accelerate growth and development process. 

4- Lord Keynes published the famous book ‘General theory of employment, interest and money.’ In this book, he used the macroeconomics approach in studying economic problems. After that, macroeconomics became an important approach in economic analysis.

Micro and Macro approaches are complementary.

Explanation: 

Micro and macro approaches are complementary. To know well about the working of an economy, one must have the knowledge of both the branches of economics. It can be said that macroeconomics uses the principles of microeconomics as its foundation and the former is a magnified version of the latter.

False 

Explanation: 

The above statement is not true. Macroeconomics is the study of aggregates. It studies how an economy operates as a whole. It focuses on aggregate measures such as aggregate demand, aggregate supply and aggregate price level. It also studies how these variables are determined and how they change over time.

False 

Explanation: 

The above statement is incorrect. An increase in the national income is a macroeconomic goal. Besides this, macroeconomics focuses on aggregate measures such as aggregate demand, aggregate supply and aggregate price level and confronts major problems such as poverty, unemployment, inflation and BOP disequilibrium.

False 

Explanation: 

The statement is incorrect, as price determination is the subject matter of microeconomics. Microeconomics studies how prices are determined in both the commodity and factor markets based on the demand and supply analysis.

True 

Explanation: 

The above statement is correct. Macroeconomics is also known as the ‘Theory of Income and Employment’, or income analysis, as it focuses on how income and employment levels are determined in an economy

Macroeconomics is also known as the ‘Theory of Income and Employment’, or income analysis, as it focuses on how income and employment levels are determined in an economy and what causes fluctuations in them. In addition macroeconomics also explains the factors that lead to increase in the output, income and employment in the long run.

Macroeconomics is the study of aggregates; as it studies the economy as a whole, rather than the individual economic units as a consumer or a producer. It studies the aggregates such that they cover the entire economy. For instance, it studies national income rather than individual income. Similarly, it studies aggregate price levels rather than price level of a particular commodity

The macroeconomic approach to economics has been in existence since the earlier time, though its use in economic analysis is modern and recent. In the past, macroeconomics did not exist as a separate branch of economic analysis but this approach prevailed even before the evolution of microeconomics.

Evidence is available that, even in the 16^th and the 17^th century, policies of the government were based on the macro approach. In the 18^th century, physiocrats tried to analyse the concept of national income and wealth. Several classical economists, such as Adam Smith, Prof. Ricardio, J.S.Mill etc. also discussed the determination of national income and wealth.

In 1936, John M. Keynes published his famous book “General theory of employment, interest and money”. He used the macroeconomic approach to solve economic problems. After the publication of this book, macroeconomics became important and popular to economic analysis.

In macroeconomics, we study how an economy operates as a whole. It focuses on the aggregate measures such as aggregate demand, aggregate supply, aggregate price level etc. It studies how these variables are determined and how they change over time. It helps us in understanding various economic relationships and economic problems at the economy or aggregate level. It is also known as the ‘Theory of Income and Employment’ as its main focus is on how income and employment levels are determined. In macroeconomics, we confront major problems such as poverty, unemployment, inflation, BOP disequilibrium etc.

The following are the subject matter of macroeconomics: 

i. Theory of income and employment: Macroeconomics explains the determination of national income and employment. In addition it also helps in analysing the cause and effect of fluctuations in them. For this, various concepts such as consumption function, investment function, business cycles are studied. 

ii. Theory of general price level and inflation: Macroeconomics studies how the general level prices in an economy are determined and the effects of fluctuations on them. Such study is specifically important to understand and combat the effect of such problems as depression and recession. 

iii. Theory of economic growth and development: Macroeconomic study helps in understanding the causes of underdevelopment and other socioeconomic problems such as poverty and inequality in an economy. Accordingly, it helps in determining suitable policies to combat the same. Similarly, it helps to deals with such problems as underutilisation of resources, thereby, help in working towards increasing the productive efficiency in the economy. 

iv. Macro theory of distribution: The study of macroeconomics helps in determining how the national income would be distributed among the various sections in the economy in the form of rent, wages, income and profit. Some of the important theories in this regard are given by Ricardo, Karl Marx, Kalecki, Kaldor.

e) Policy-oriented: - Macroeconomic analysis helps in formulating policies. These policies help in creating new employment opportunities. Also, they pull the economy out of the low level of income and demand. 

f) Dynamic: - Macroeconomics basically deals with the changes in the economy. It studies how macroeconomic variables such as aggregate demand, aggregate supply, aggregate price level etc. are determined and how they change over time.

The above statement is not correct as macroeconomics is that branch of economics which deals with the study of aggregates covering the entire economy. It is concerned with total employment, national income, national output, aggregate demand, aggregate supply, aggregate consumption and savings, total investment etc. On the other hand, microeconomics deals with the study of individual behaviour.

f) Interdependence among variables: Macroeconomics takes into consideration the interdependence among the various economic variables. In other words, it explains how changes in one variable influence the change in other.

The above statement is not correct. Macroeconomics is a general equilibrium analysis. 

It studies all the economic variables simultaneously and also takes into account the functional relationship of these variables. 

This approach assumes “everything depends on everything else”. On the other hand, partial equilibrium is the method of study in microeconomics.

In macroeconomics, we study how an economy operates as a whole. It focuses on the aggregate measures such as aggregate demand, aggregate supply, aggregate price level etc. It studies how these variables are determined and how they change over time. It helps us in understanding various economic relationships and economic problems at the economy or aggregate level. It is also known as the ‘Theory of Income and Employment’ as its main focus is on how income and employment levels are determined. In macroeconomics, we confront major problems such as poverty, unemployment, inflation, BOP disequilibrium etc. 

The following are the important macroeconomic theories. 

i. Theory of national income: Macroeconomics helps in the national income analysis. It provides various methods to calculate the national income. 

ii. Theory of employment: Macroeconomics also helps in determining the level of employment and unemployment in an economy. 

iii. Theory of Money: Macroeconomics studies the functions and theories of money. It is useful in analysing the effect of a change in demand and supply of money on the employment levels. 

iv. Theory of general price level: Macroeconomics studies how the general level prices in an economy are determined and the effects of fluctuations on them. 

v. Theory of international trade: It helps in understanding trade between two different countries, the rules and regulations followed, policies etc. 

vi. Theory of economic growth: Macroeconomics emphasises on how to increase the per capita income or national income. It aims at accelerating the economic growth.

The above statement is correct. Macroeconomics is quite different from microeconomics. Macroeconomics is concerned with large sections of the economy or the economy as a whole. It is that branch of economics which deals with the economics activities by all the economic spheres, varying economic situations and economic problems of the economy as a whole. Microeconomics, on the other hand, studies only one individual consumer or one individual producer like the households, firms, consumers etc.

The above statement is not correct. Macroeconomics is not individualistic as it does not study only one individual consumer or one individual producer. In fact, macroeconomics studies the behaviour, problems and the economic situation of all the consumers at a time. In other words, it can be said that macroeconomics involves aggregation of all the consuming units.

The above statement is correct. Macroeconomics is all about the complete utilization of resources, full employment level, price stability, and growth of the economy. No economy is capable enough in utilizing all of its resources effectively and efficiently. In some economies, resources are underutilized, while in some economies resources are over utilized. To achieve an ever increasing growth rate and efficient utilization of resources, it is necessary to use macroeconomic models and policies. Since all the economies follow and frame macroeconomic policies for their economic growth, it can be said that it has a wide scope.
