Topic-1.1: Concept of Economics & it’s importance
A. Introduction:
Economics is a social science that studies how individuals, businesses, governments,
and societies make choices about allocating limited resources to satisfy their
unlimited wants and needs. It examines the production, distribution, and
consumption of goods and services.
The English word economics is a derivative from the Greek word ‘Oikonomous’.
‘Oikos’ means household and ‘nomos’ means management. Hence, simple deNinition
and meaning of economics is “management of households”. The following Nigure
shows the evolution of various deNinitions by timely economic experts:

Modern economics deals with a study of choice making by individuals, institutions,
societies, nations and globe under conditions of scarcity and surplus towards maximizing
beneNits and satisfying their unlimited needs at present and future. Prof.A.C.Dhas (2011).
B. Nature of Economics:
The nature of economics can be understood by examining its foundational principles,
assumptions, and objectives.
, 1. Study of Scarcity: At the core of economics lies the concept of scarcity, which
refers to the fundamental problem of having limited resources to meet unlimited
wants and needs. This scarcity necessitates choices, as individuals, businesses,
and societies must decide how to allocate resources efNiciently to maximize utility,
satisfaction, or proNit.
2. Choice and Opportunity Cost Analysis: Economics emphasizes the necessity of
making choices. When making decisions, individuals and societies face
opportunity costs—the value of the next best alternative forgone. Understanding
opportunity costs helps in evaluating trade-offs and making informed decisions
about resource allocation.
3. Behaviour Study: Economics often operates on the assumption of rational
behaviour, where individuals and Nirms aim to maximize their objectives (e.g.,
utility, proNit) given the constraints they face. This assumption allows economists
to analyse and predict behaviour in various economic contexts, although real-
world behaviour may deviate from strict rationality due to cognitive limitations,
emotions, or other factors.
4. Marginal Cost BeneIits: This involves evaluating decisions based on marginal
beneNits and marginal costs. By examining the additional beneNits and costs of
incremental changes or choices, individuals and Nirms can optimize their
decisions to achieve desired outcomes.
5. Interdependence: Economics recognizes the interdependence of economic
agents (e.g., consumers, producers, governments) and markets. Decisions made
by one agent or in one market can have ripple effects on others, leading to complex
interactions and outcomes within the economy.
6. Positive and Normative: Economics encompasses both positive and normative
analysis. Positive economics involves objective, fact-based analysis of economic
phenomena, focusing on what is or what will be. In contrast, normative economics
involves subjective, value-based analysis that addresses what ought to be or what
should be done based on ethical, political, or social considerations. Both
approaches contribute to understanding economic issues and informing policy
debates and decisions.
7. Dynamic Discipline in Contemporary: Economics is a dynamic and evolving
discipline that adapts to changing economic conditions, technological
advancements, institutional developments, and global events. Economists
continuously develop theories, models, and methodologies to analyze new
challenges, generate insights, and inform policy responses to complex economic
issues facing individuals, societies, and nations.
C. Scope of Economics:
1. Consumer & Producer Behaviour: Examines how consumers make choices
about what goods and services to consume based on preferences, budget
constraints, and prices. It also studies how Nirms make decisions about
production, pricing, input choices, and market competitiveness
, 2. Market Structures: Analyses different market structures (e.g., perfect
competition, monopoly, monopolistic competition, oligopoly) and their
implications for pricing, output, efNiciency, and market performance.
3. Resource Allocation: Investigates how resources (e.g., labour, capital, natural
resources) are allocated among competing uses to maximize efNiciency and
welfare.
4. Unemployment and InIlation: Analyses causes, consequences, and policies
related to unemployment, inNlation, and economic stability.
5. Monetary and Fiscal Policy: Examines the role of central banks and
governments in managing money supply, interest rates, taxation, government
spending, and economic stabilization.
6. International Trade and Finance: Investigates global economic interactions,
trade policies, exchange rates, balance of payments, and international Ninancial
institutions.
7. Property Rights and Institutions: Examines the role of property rights, legal
systems, and institutions in promoting economic growth, stability, and
development.
8. Public Goods and Externalities: Studies the provision, Ninancing, and
management of public goods, as well as the effects of externalities (positive or
negative spillover effects) on market outcomes.
9. Human Capital: Studies the role of education, health, skills, and knowledge in
promoting economic development and poverty alleviation.
10. Infrastructure and Investment: Analyses the importance of infrastructure
development, investment, technology transfer, and foreign aid in fostering
economic growth and development.
11. Institutional Reforms: Investigates the impact of governance, institutions,
policies, and reforms on economic performance, social welfare, and sustainable
development.
12. Trade Theory and Policy: Examines theories of comparative advantage, trade
patterns, protectionism, trade agreements, and globalization.
13. Exchange Rates and Balance of Payments: Studies exchange rate systems,
currency markets, international Ninance, and policies related to trade imbalances
and external stability.
14. Globalization and Economic Integration: Analyses the drivers, beneNits, costs,
and challenges of globalization, regional integration, multinational corporations,
and international economic institutions.
15. Public Expenditure and Taxation: Examines government spending, taxation,
public Ninance, budgetary policies, and Niscal sustainability.
16. Social Welfare and Redistribution: Studies social welfare programs, income
distribution, poverty alleviation, inequality, and policies aimed at promoting
equity and social justice.
