Chapter 1  Introduction to Macro Economics

Introduction

The subject Economics is classified into two branches, namely, Micro Economics and Macro Economics. Ragnar Frisch, a Norwegian economist and the co-recipient of the first Nobel Prize in Economic Sciences coined the words ‘micro’ meaning small and ‘macro’ meaning large in the year 1933. However, macroeconomics in its modern form, began with John Maynard Keynes and his book “The General Theory of Employment, Interest and Money” published in 1936. Keynes offered an explanation for fallout from the Great Depression, when goods remained unsold and workers unemployed. Hence, Keynes is regarded as the ‘Father of Modern Macro Economics’.

29. Describe the different types of economic systems.

There are three major types of economic systems. They are:

1. Capitalistic Economy (Capitalism):

• Capitalistic economy is also termed as a free economy (Laissez faire, in Latin) or market economy where the role of the government is minimum and market determines the economic activities.
• The means of production in a capitalistic economy are privately owned.
• Manufacturers produce goods and services with profit motive.
• The private individual has the freedom to undertake any occupation and develop any skill.
• The USA, West Germany, Australia and Japan are the best examples for capitalistic economies.
• How ever, they do undertake large social welfare measures to safeguard the downtrodden people from the market forces.

2. Socialistic Economy (Socialism):

30. Outline the major merits of capitalism.

Merits of Capitalism:

Automatic Working:

• Without any government intervention, the economy works automatically.

Efficient Use of Resources:

• All resources are put into optimum use.

Incentives for Hard work:

• Hard work is encouraged and entrepreneurs get more profit for more efficiency.

Economic Progress:

• Production and productivity levels are very high in capitalistic economies.

Consumers Sovereignty:

• All production activities are aimed at satisfying the consumers.

Higher Rates of Capital Formation:

• Increase in saving and investment leads to higher rates of capital formation.

Development of New Technology:

• As profit is aimed at, producers invest on new technology and produce quality goods.

31. Indicate the demerits of socialism.

Demerits of Socialism:
1. Red Tapism and Bureaucracy:

• As decision are taken by government agencies, approval of many officials and movement of files from one table to other takes time and leads to red tapism.

2. Absence of Incentive:

• The major limitation of socialism is that this system does not provide any incentive for efficiency. Therefore, productivity also suffers.

Limited Freedom of Choice:

• Consumers do not enjoy freedom of choice over the consumption of goods and services.

4. Concentration of Power:

• The State takes all major decisions. The private takes no initiative in making economic decisions. Hence, the State is more powerful and misuse of power can also take place.

32. Enumerate the features of mixed economy.

Features of Mixed Economy:
1. Ownership of Property and Means of Production: 

• The means of production and properties are owned by both private and public. Public and Private have the right to purchase, use or transfer their resources.

2. Coexistence of Public and Private Sectors:

• In mixed economies, both private and public sectors coexist. Private industries undertake activities primarily for profit. Public sector firms are owned by the government with a view to maximize social welfare.

3. Economic Planning:

• The central planning authority prepares the economic plans. National plans are drawn up by the Government and both private and public sectors abide. In general, all sectors of the economy function according to the objectives, priorities and targets laid down in the plan.

4. Solution to Economic Problems:

• The basic problems of what to produce, how to produce, for whom to produce and how to distribute are solved through the price mechanism as well as state intervention.

5. Freedom and Control:

• Though private has freedom to own resources, produce goods and ‘ services and distribute the same, the overall control on the economic activities rests with the government.

33. Distinguish between Capitalism and Globalism.

Capitalism:

• The system where the means of production are privately owned and market determines the economic activities.

Globalism:

• An economic system where the economic activities of a nation are inter connected and inter dependent on each other nation.

34. Briefly explain the two sector circular flow model.

Circular Flow of Income in a Two-Sector Economy:

• There are only two sectors namely, household sector and firm sector.

1. Household Sector:

• The household sector is the sole buyer of goods and services, and the sole supplier of factors of production, i.e., land, labour, capital and organisation.
• It spends its entire income on the purchase of goods and services produced by the business sector.
• The household sector receives income from firm sector by providing the factors of production owned by it.

2. Firms:

• The firm sector generates its revenue by selling goods and services to the household sector.
• It hires the factors of production, i.e., land, labour, capital and organisation, owned by the household sector.
• The firm sector sells the entire output to households.
• In a two – sector economy, production and sales are equal and there will be a circular flow of income and goods.
• The outer circle represents real flow (factors and goods) and the inner circle represents the monetary flow (factor prices and commodity prices).
• Real flow indicates the factor services flow from household sector to the business sector, and goods and services flow from business sector to the household.
• The basic identities of the two-sector economy are as under:

        Y = C + 1

Where

Y is Income; C is Consumption; I is investment.

Answer the following questions in one page

35. Discuss the scope of Macro Economics.

The study of macro economics has wide scope and it covers the major areas as follows:

1. National Income:

• Measurement of national income and its composition by sectors are the basic aspects of macroeconomic analysis. The trends in National Income and its composition provide a long term understanding of the growth process of an economy.

2. Inflation:

• It refers to steady increase in general price level. Estimating the general price level by constructing various price index numbers such as Wholesale Price Index, Consumer Price Index, etc, are needed.

3. Business Cycle:

• Almost all economies face the problem of business fluctuations and business cycle. The cyclical movements (boom, recession, depression and recovery) in the economy need to be carefully studied based on aggregate economic variables.

4. Poverty and Unemployment:

• The major problems of most resource – rich nations are poverty and unemployment. This is one of the economic paradoxes. A clear understanding about the magnitude of poverty and unemployment facilitates allocation of resources and initiating corrective measures.

5. Economic Growth:

• The growth and development of an economy and the factors determining them could be understood only through macro analysis.

6. Economic Policies:

• Macro Economics is significant for evolving suitable economic policies. Economic policies are necessary to solve the basic problems, to overcome the obstacles and to achieve growth.

36. Illustrate the functioning of an economy based on its activities.

• An economy is referred to any system or area where economic activities are carried out. Each economy has its own character. Accordingly, the functions or activities also vary. The functioning of an economy by its activities is explained in flow chart.
• In an economy, the fundamental economic activities are production and consumption.
• These two activities are supported by several other activities.
• The ultimate aim of these activities is to achieve growth. The ‘exchange activity’ supports the production and consumption activities. These activities are influenced by several economic and non – economic activities.
• The major economic activities include transportation, banking, advertising, planning, government policy and others.
• The major non – economic activities are environment, health, education, entertainment, governance, regulations etc.
• In addition to these supporting activities, external activities from other economies such as import, export, international relations, emigration, immigration, foreign investment, foreign exchange earnings, etc. also influence the entire functioning of the economy.

37. Compare the features of capitalism and socialism.

    Features of Capitalistic Economy:

1. Private Ownership of Property and Law of Inheritance:

• The basic feature of capitalism is that all resources namely, land, capital, machines, mines etc. are owned by private individuals. The owner has the right to own, keep, sell or use these resources according to his will. The property can be transferred to heirs after death.

2. Freedom of Choice and Enterprise:

• Each individual is free to carry out any occupation or trade at any place and produce any commodity. Similarly, consumers are free to buy any commodity as per their choice.

3. Profit Motive:

• Profit is the driving force behind all economic activities in a capitalistic economy. Each individual organization produce only those goods which ensure high profit. Advance technology, division of labour, and specialisation are followed. The golden rule for a producer under capitalism is ‘to maximize profit.’

4. Free Competition:

• There is free competition in both product and factor market. The government or any authority cannot prevent firms from buying or selling in the market. There is competition between buyers and sellers.

5. Price Mechanism:

• Price mechanism is the heart of any capitalistic economy. All economic activities are regulated through price mechanism i.e., market forces of demand and supply.

6. Role of Government:

• As the price mechanism regulates economic activity, the government has a limited role in a capitalistic economy. The government provides basic services such as, defense, public health, education, etc.

7. Inequalities of Income:

• A capitalist society is divided into two classes – ‘haves’ that is those who own property and ‘have-nots’ who do not own property and work for their living. The outcome of this situation is that the rich become richer and poor become poorer. Here, economic inequality goes on increasing.

Features of Socialism:

1. Public Ownership of Means of Production:

• All resources are owned by the government. It means that all the factors of production are nationalized and managed by the public authority.

2. Central Planning:

• Planning is an integral part of a socialistic economy. In this system, all decisions are undertaken by the central planning authority.

3. Maximum Social Benefit:

• Social welfare is the guiding principle behind all economic activities. Investments are planned in such a way that the benefits are distributed to the society at large.

4. Non – existence of Competition:

• Under the socialist economic system there is absence of competition in the market. The state has full control over production and distribution of goods and services. The consumers will have a limited choice.

5. Absence of Price Mechanism:

• The pricing system works under the control and regulation of the central planning authority.

6. Equality of Income:

• Another essential feature of socialism is the removal and reduction of economic inequalities. Under socialism private property and the law of inheritance do not exist.

7. Equality of Opportunity:

• Socialism provides equal opportunity for all through free health, education and professional training.

8. Classless Society:

• Under socialism, there is a classless society and so no class conflicts. In a true socialist society, everyone is equal as far as economic status is concerned.

38. Compare the feature among Capitalism, Secularism and Mixedism.
