Economics stems from the Greek term Oikonomos, combining oikos (house) and nomos (law), essentially translating to “Rules of the Household.” It is a social science focusing on the production, distribution, and consumption of goods and services. Historically, economics centered on wealth, emphasizing production and consumption. This scope was limited, often excluding vulnerable groups like the poor, elderly, and children. The advent of welfare economics corrected this, highlighting the welfare of the entire society.

Branches of Economics

Economics is traditionally divided into two main branches: Microeconomics and Macroeconomics, along with several other specialized fields.

1. Microeconomics: Studies the interaction of supply and demand in individual markets and how these determine the price level. It looks at the economic behaviors of individual actors such as firms, consumers, and workers.
2. Macroeconomics: Examines the functioning of the overall economy, covering topics like employment, GDP, and inflation. It focuses on national income, poverty, and other economy-wide features.
3. Development Economics: Explores economic aspects of low-income countries. The primary goal is to determine how poor nations can be transformed into prosperous ones.
4. Behavioral Economics: Investigates how social, cognitive, and emotional factors affect individuals’ economic decisions, often leading to irrational behaviors that diverge from traditional economic models.
5. Environmental Economics: Studies the impact of economic activities on the environment and aims to balance economic activities with environmental sustainability.
6. International Economics: Focuses on economic interactions between different countries, covering foreign trade, exchange rates, and balance of payments. The principle of comparative advantage is central to this branch.
7. Information Economics: Examines the influence of information technology on the economy. Key characteristics include ease of creation and dissemination but difficulty in trust and control.
8. Demographic Economics: Applies economics to the study of population dynamics, including size, growth, density, and distribution.

Types of Economies

Economies are categorized based on government involvement and decision-making mechanisms.

1. Traditional Economy: Minimal government involvement; resource allocation based on customs and habits. Economic roles are familial, often limiting individual choice. Examples: Tribes in the Amazon, Australian Aborigines.
2. Free Market Economy: Very limited government interference. Decisions are driven by market forces with intense competition and numerous consumer choices. Private ownership aims for profit maximization. Examples: United States, Australia.
3. Command Economy: Government-controlled resources and planning. Absence of competition results in inefficient allocation and limited consumer choices. Examples: Cuba, North Korea.
4. Mixed Economy: A blend of public and private sectors, with the government directing the public sector and individuals and businesses managing the private sector. Examples: India, Russia, UK.
5. Open Economy: Engages in international trade, free from major trade barriers. The degree of openness affects the government’s policy-making freedom and its exposure to global economic cycles.
6. Closed Economy: No international trade; all goods are produced and consumed within national borders. The government acts as the central arbiter.
7. Capitalist Economy: Private ownership of production and distribution; characterized by competition, where the laws of supply and demand drive the economy.
8. Socialist Economy: Production means are socially owned, emphasizing human needs over profit. Cooperation replaces competition, often with strong government control. Variants include communism, which advocates for class struggle to achieve a cooperative society.

Sectors of an Economy

Economies are divided into sectors based on the nature of economic activities. This classification reflects the distance from the natural environment.

1. Primary Sector: Involves extraction or harvesting of natural resources, including agriculture, mining, and fishing. As economies develop, this sector’s share decreases in production and employment.
2. Secondary Sector: Engages in the manufacturing and processing of finished goods. Activities include metalworking, textile production, and shipbuilding. Typically, the secondary sector dominates during a country’s middle phase of development, although some countries like India transitioned directly to the tertiary sector.
3. Tertiary Sector: Also known as the services sector, it encompasses activities like retail, transportation, and banking. In advanced economies, this sector usually contributes the most to production and employment.

Important Note: In some models, the Quaternary and Quinary sectors are also recognized, though they often fall under the tertiary category.

4. Quaternary Sector: Involves intellectual activities like research, information technology, education, and financial planning.
5. Quinary Sector: Represents the highest level of decision-making, including top officials in government, media, and universities.

Classification of Countries by the World Bank

The World Bank classifies countries based on per capita income in its World Development Report (WDR). As of July 2018, the categories are:

Classification of Countries Based on Economic Activities

1. Developed Country: High levels of economic growth and security, assessed by per capita income, GDP, industrialization, and infrastructure.
2. Developing Country: Features lower living standards, underdeveloped industries, and a low Human Development Index (HDI).
3. Least Developed Country: Characterized by the lowest socio-economic indicators and HDI ratings as defined by the United Nations.

Important Note: The HDI considers various factors, including health, education, and income, to provide a comprehensive measure of human well-being.

Comparative Analysis of Economic Systems

Important Concept: Mixed economies blend elements of both capitalism and socialism, creating a balanced approach to resource allocation and economic development.
