This note covers the meaning of an economic system, the central problems every economy must solve, the three types of economic systems (capitalism, socialism and mixed economy) with their features, merits and demerits, the mechanisms each system uses to decide what, how and for whom to produce, the role of government alongside the price mechanism, the characteristics that distinguish developed and developing economies, and a basic introduction to regional and global economic groupings such as SAARC, the European Union, ASEAN, the G-8 and the G-20.

What problems must every economic system solve?

Every society faces scarcity of resources compared with the wants of its people. Because resources such as land, labour, capital and raw materials are limited, every economy must decide how to use them. These are called the central problems of an economy, and they are usually stated as three questions.

  1. What to produce and in what quantities? Whether to produce more food, clothing or housing; more agricultural goods or industrial goods; more consumption goods or investment goods.
  2. How to produce? Whether to use more labour or more machines, and which technology to adopt in producing each good.
  3. For whom to produce? How the goods and services produced should be distributed among the people of the economy, and who gets more and who gets less.

Any allocation of scarce resources gives a particular combination of goods and services; the goods produced then have to be distributed among people.

The allocation of resources and the distribution of the final mix of goods and services are the two basic economic problems that any economic system must try to solve.

Every economy, whatever system it follows, has to choose one of the many production possibilities open to it. The choice is forced on it because resources are scarce and have competing uses.

What is an economic system, and what are its main types?

Definition: Economic system. An economic system is the mechanism, or set of institutions and rules, through which a society decides what to produce, how to produce it and for whom to produce it, and allocates its scarce resources accordingly.

Basic economic problems can be solved either through the free interaction of individuals pursuing their own objectives, as happens in a market economy, or in a planned manner by a central authority such as the government, as happens in a centrally planned economy.

In reality, every actual economy is a mixed economy, where some decisions are taken by the government and others are left to the market; economies differ only in the extent of the government's role.

Three broad types of economic system are usually described: capitalism, socialism and the mixed economy.

Each type answers the three central questions in its own way. Capitalism leaves the answers mainly to prices in free markets, socialism leaves them mainly to a planning authority, and the mixed economy divides the work between the two.

What is capitalism and how does it work?

Definition: Capitalism. Capitalism is an economic system in which productive resources are privately owned, production decisions are guided by the profit motive, and the basic problems of what, how and for whom to produce are solved mainly through the free working of the price mechanism in the market.

In a market economy, all economic activities are organised through the market, which is an institution that organises the free interaction of buyers and sellers.

Buyers and sellers do not need to meet in a physical marketplace; exchange can happen through a village market, a shop, or over the telephone or internet.

Goods and services come with a price that is mutually agreed between buyers and sellers, and this price reflects, on average, how much society values that good.

If buyers demand more of a good, its price rises. This signals to producers that society wants more of that good than is currently being produced, and producers respond by increasing output.

In this way, prices send information across the market and coordinate the activities of millions of separate individuals without any central authority telling them what to do.

This system of coordination through prices is the price mechanism, and under capitalism it is the main mechanism used to decide what to produce, how to produce it and for whom it is produced: goods go to whoever is willing and able to pay the market price.

Merits of capitalism

  • The price mechanism automatically coordinates the decisions of a very large number of individuals without a central planning authority having to collect and process huge amounts of information.
  • The profit motive and private ownership give producers a strong incentive to cut costs, innovate and respond quickly to changes in consumer demand.
  • Consumers have freedom of choice because resources flow towards the goods that people are willing to pay for.
  • Competition among producers tends to keep prices in line with costs and encourages efficient use of resources.

Demerits of capitalism

  • Goods and services go mainly to those who can pay the market price, so the system can leave some people without a minimum standard of living if their incomes are very low.
  • Goods that are important for society, such as basic education or health services, may not be produced in adequate amounts if they are not privately profitable.
  • Unequal ownership of resources can lead to a very unequal distribution of income and wealth.
  • The system can be unstable, with periods of boom followed by periods of depression and unemployment.

What is socialism and how does it work?

Definition: Socialism. Socialism is an economic system in which the government or a central planning authority owns or controls the major means of production and takes the key decisions on what, how and for whom to produce, with the aim of distributing the final mix of goods and services in a way that is considered desirable for society as a whole.

In a centrally planned economy, the government plans all the important economic activities. All important decisions regarding production, exchange and consumption of goods and services are made by the central authority rather than being left to individual producers and consumers.

If a good or service important for the prosperity and well-being of the economy, such as education or health, is not being produced in adequate amounts by individuals on their own, the government may itself decide to produce it, or induce others to produce it.

If some people receive so small a share of the final mix of goods and services that their survival is at stake, the central authority may intervene to achieve a more equitable distribution.

The closest example of a centrally planned economy was China for the major part of the twentieth century.

Merits of socialism

  • The central authority can direct resources towards goods and services, such as education and health, that are socially important but might otherwise be underproduced.
  • Planning allows the government to aim deliberately at a more equitable distribution of goods and services among the people of the economy.
  • Large-scale, long-term projects that an individual producer could not finance can be undertaken by the central authority.
  • Resources can, in principle, be directed away from wasteful or luxury uses towards the needs that the planners judge to be most important.

Demerits of socialism

  • Planning requires the central authority to gather and process an enormous amount of information about resources, technology and the wants of millions of individuals, which is difficult to do accurately.
  • Because production decisions are not guided by individual profit and price signals, the system can be slower to respond to changes in consumer demand.
  • Producers and managers may have a weaker incentive to control costs or innovate if rewards are not closely linked to performance.
  • Individual freedom of choice in production and consumption is more restricted than under a market system.

What is a mixed economy, and what mechanism does it use?

Definition: Mixed economy. A mixed economy is an economic system in which some important economic decisions are taken by the government and the rest of economic activity is, by and large, conducted through the market, so that the price mechanism and government planning work side by side.

In practice, all economies are mixed economies; the only difference between them is the extent of the government's role in deciding the course of economic activity.

In the United States of America the role of government is minimal, while in India, since independence, the government has played a major role in planning economic activities, although this role has been reduced considerably in the last couple of decades.

In a mixed economy, the price mechanism continues to coordinate most day-to-day decisions on what, how and for whom to produce, because prices still signal scarcity and demand to producers and consumers.

Alongside this, the government steps in where the market outcome is judged undesirable: it may regulate prices, provide goods such as education and health directly, redistribute income through taxes and subsidies, or produce goods that private producers find unprofitable but that society needs.

The role of government is thus used to emphasise fairness and the provision of socially important goods, while the price mechanism is relied upon as the main tool for the everyday allocation of resources.

Merits of a mixed economy

  • It combines the efficiency and incentive advantages of the price mechanism with the government's ability to correct the shortcomings of the pure market system.
  • The government can ensure that socially important goods, such as basic education and health, are provided even where they are not fully profitable.
  • It allows a degree of planning for equitable distribution while still leaving most production and consumption choices to individual decision-makers.

Demerits of a mixed economy

  • Deciding exactly how much the government should intervene, and in which markets, is a continuing practical and political problem.
  • Excessive government regulation can blunt the incentives and price signals that make the market mechanism efficient.
  • Coordinating government planning with the independent decisions of private producers and consumers can create delays or inconsistencies.

How does the price mechanism solve the central problems in practice?

The price mechanism is the process by which the prices of goods, services and resources, set by the free interaction of demand and supply, guide decisions on what to produce, how to produce it and for whom it is produced.

A rise in the price of a good signals to producers that it is in higher demand than is currently being supplied, and producers typically respond by increasing production; a fall in price signals the opposite.

In this way, the price of each good and resource carries information to every participant in the market, and millions of separate decisions get coordinated without any single authority issuing instructions.

Even where an economy relies mainly on government planning, prices still carry some information, and even where an economy relies mainly on the market, the government is usually involved in some decisions, for example by fixing minimum support prices, regulating monopolies or providing certain goods directly.

The role of government alongside the price mechanism is therefore not an either-or choice: the two work together in every actual economy, with the balance between them differing from one system to another.

What distinguishes developed and developing economies?

Definition: Developed economy. A developed economy is one with a high level of per capita income, a predominantly industrial and service-based structure of production, high literacy and life expectancy, and well-developed infrastructure and capital stock.

Definition: Developing economy. A developing economy is one with a comparatively low level of per capita income, a larger share of output and employment still dependent on agriculture, lower literacy and capital formation, and infrastructure that is still being built up.

FeatureDeveloped economiesDeveloping economies
Per capita incomeHighLow to middle
Main sector of outputIndustry and servicesAgriculture still significant
Rate of capital formationHighLower, but rising
Literacy and life expectancyHighImproving but lower
InfrastructureWell developedBeing built up

These characteristics are matters of degree rather than a sharp dividing line, and countries move between the two broad groups as their per capita income, industrial structure and human development indicators change over time.

India is generally classified as a developing economy that has been growing rapidly and reducing the role of direct government planning in its economic activities over the last few decades.

What are regional and global economic groupings?

Countries often join together in regional or global groupings to cooperate on trade, investment and economic policy, so as to gain advantages of scale and bargaining power that a single country may not have on its own.

GroupingFull formBasic nature
SAARCSouth Asian Association for Regional CooperationRegional grouping of South Asian countries, including India, for economic and regional cooperation
EUEuropean UnionEconomic and political union of European countries with a common market and, for most members, a common currency
ASEANAssociation of South East Asian NationsRegional grouping of South East Asian countries promoting trade and economic cooperation
G-8Group of EightForum of major industrialised economies, historically eight (G-8) but operating as seven (G-7) since Russia's suspension in 2014, that discusses global economic and policy issues
G-20Group of TwentyForum of major developed and developing economies, including India, that discusses global economic issues

India participates in SAARC as a South Asian member and in the G-20 as a major developing economy, alongside its engagement with groupings such as the EU and ASEAN on trade and economic cooperation.

Going beyond the syllabus

These ideas extend the unit and are not needed for the questions on it.

What is the production possibility frontier and opportunity cost?

The collection of all possible combinations of goods and services that an economy can produce from a given amount of resources and a given level of technology is called its production possibility set.

A curve joining the maximum combinations obtainable when all resources are fully and efficiently used is the production possibility frontier (PPF).

PossibilityCornCotton
A010
B19
C27
D34
E40

If all resources go into corn, a maximum of 4 units of corn can be produced; if all go into cotton, a maximum of 10 units of cotton can be produced.

A point lying strictly below the frontier shows resources that are underemployed or wasted. Since more of one good means fewer resources for the other, there is always a cost of having a little more of one good in terms of the other good that is given up.

This is the opportunity cost of an additional unit of a good, and because of its importance it is also called the economic cost.

Draw and label

Production possibility frontier for corn and cotton

Plot corn on the horizontal axis and cotton on the vertical axis.

Mark the points A(0,10), B(1,9), C(2,7), D(3,4) and E(4,0), and join them into a smooth, bowed-outward curve from the cotton axis to the corn axis.

Any point on the curve is a fully efficient combination; points below it show unemployed or wasted resources.

Worked example 1. An economy can use its resources to produce either corn or cotton, as in the possibilities A(0,10), B(1,9), C(2,7), D(3,4) and E(4,0). The economy is currently at possibility B, producing 1 unit of corn and 9 units of cotton, but policymakers want 2 more units of corn.

Answer: Moving from possibility B to possibility D (3 units of corn) would raise corn output by 2 units, from 1 to 3, but cotton output would fall from 9 units to 4 units, a loss of 5 units of cotton. This opportunity cost of 5 units of cotton is what the policymakers must give up to reach their target of 2 more units of corn by moving from possibility B to possibility D.

Common errors and misconceptions

  • Misconception: capitalism means no government involvement at all. Correct: even in a predominantly market economy, the government is usually involved in some decisions; no real economy is purely capitalist.
  • Misconception: socialism means there is no market at all. Correct: socialist systems may still use prices for some decisions; the defining feature is that the central authority takes the key production and distribution decisions.
  • Misconception: a mixed economy is simply "half capitalist and half socialist" in equal measure. Correct: every real economy is mixed, and economies differ only in how much weight is given to government planning versus the market.
  • Misconception: the price mechanism works only in a purely capitalist economy. Correct: prices carry information in every economy; in a mixed economy the government works alongside the price mechanism rather than replacing it.
  • Misconception: the role of government and the price mechanism are alternatives, and an economy must choose one. Correct: the two work together in every actual economy, and the balance between them differs from one system to another.
  • Misconception: developed and developing are fixed, permanent categories. Correct: they describe a country's current level of per capita income and structure of production, which can change over time.
  • Misconception: SAARC, the EU, ASEAN, the G-8 and the G-20 are the same kind of grouping. Correct: they differ in membership and depth of integration, from a regional cooperation body to an economic and political union to policy-discussion forums.

Q9. Explain how the price mechanism solves the central problems of an economy, and state two limitations of relying on it alone. [8 marks]
  1. The price mechanism is the process by which the prices of goods, services and resources, set by the free interaction of demand and supply, guide decisions on what to produce, how to produce it and for whom it is produced.
  2. What to produce: if buyers demand more of a good, its price rises, which signals to producers that society wants more of that good than is currently being produced.
  3. How to produce: producers choose the combination of resources and technology that keeps their costs low, since a lower cost at the going price leaves a larger profit.
  4. For whom to produce: goods go to whoever is willing and able to pay the market price, so the distribution of output follows the distribution of purchasing power.
  5. Coordination: prices send information across the market and coordinate the activities of millions of separate individuals without any central authority telling them what to do.
  6. Limitation: goods and services go mainly to those who can pay the market price, so the system can leave some people without a minimum standard of living if their incomes are very low.
  7. Limitation: goods that are important for society, such as basic education or health services, may not be produced in adequate amounts if they are not privately profitable.
  8. For these reasons the government works alongside the price mechanism in every actual economy, and the balance between them differs from one system to another.

Test yourself

What is meant by the "for whom to produce" problem?

It is the question of how the final goods and services produced in an economy should be distributed among the people, and who gets more and who gets less.

What mainly decides what to produce under capitalism?

The price mechanism, guided by the profit motive and private ownership of resources, mainly decides what is produced.

Who takes the main production decisions under socialism?

The government or a central planning authority takes the main decisions on what, how and for whom to produce.

Give one reason why every real economy is described as a mixed economy.

Because in every economy some decisions are taken by the government and the rest of economic activity is conducted through the market; economies differ only in the extent of government involvement.

Name one feature that usually distinguishes a developed economy from a developing economy.

A developed economy typically has a higher level of per capita income than a developing economy.

What is SAARC?

SAARC, the South Asian Association for Regional Cooperation, is a regional grouping of South Asian countries, including India, for economic and regional cooperation.

What is the role of government alongside the price mechanism in a mixed economy?

The government steps in where the market outcome is judged undesirable, for example by providing education and health directly, redistributing income, or producing goods that private producers find unprofitable.

Worked example 2. Country X relies almost entirely on private firms, profit motive and free prices to decide what is produced, while Country Y has a central planning authority that owns the major industries and decides production targets directly. A student is asked to classify each country's economic system.

Answer: Country X should be classified as following the market/capitalist mechanism, because the price mechanism and private ownership are doing the main work of solving the central problems. Country Y should be classified as following the centrally planned/socialist mechanism, because the central authority is taking the key decisions on production and distribution instead of leaving them to the market.

Worked example 3. In a city, the price of onions rises sharply because demand has increased while supply has stayed the same. A trader must decide how to respond.

Answer: The rise in price signals to the trader that onions are in greater demand relative to supply than before. Following the price mechanism, the trader should increase the quantity of onions supplied to the market, since the higher price makes it profitable to bring in more stock, and this response helps bring demand and supply back towards balance.

Worked example 4. Country M has a high per capita income, most of its workforce in industry and services, high literacy and well-developed infrastructure. Country N has a much lower per capita income, a large share of its workforce still in agriculture, and infrastructure that is still being built up. A student must classify each country.

Answer: Country M should be classified as a developed economy, because it shows high per capita income, an industrial and service-based structure, high literacy and developed infrastructure. Country N should be classified as a developing economy, because it shows lower per capita income, continued dependence on agriculture and infrastructure that is still being built up.
