Principles of Economics (Course Code: ECO1CJ101) is the foundational Major Core course prescribed for First Semester students of the BA Economics Honours programme under the University of Calicut Four-Year Undergraduate Programme (CUFYUGP 2026 / FYUGP) regulations.
This paper establishes the bedrock of modern economic analysis, introducing students to marginal thinking, trade-offs, market mechanisms, production functions, and competitive equilibrium.

Detailed Module Breakdown & Core Concepts
Module 1: Ten Principles of Economics & Decision-Making
Module 1 introduces N. Gregory Mankiw's famous ten principles of economics divided into three core categories:
- How People Make Decisions: Scarcity, opportunity cost, rational people thinking at the margin, and response to incentives.
- How People Interact: Trade can make everyone better off, markets are usually a good way to organize economic activity (Adam Smith's Invisible Hand), and governments can sometimes improve market outcomes (addressing market failure, externalities, and market power).
- How the Economy as a Whole Works: A country's standard of living depends on its ability to produce goods and services, prices rise when the government prints too much money (inflation), and society faces a short-run trade-off between inflation and unemployment (Phillips Curve).
Module 2: Thinking Like an Economist
Module 2 focuses on economic methodology:
- The Scientific Method: Developing hypotheses, observing empirical reality, and using assumptions to simplify complex realities.
- Economic Models: The Circular Flow Diagram (households vs. firms, markets for goods vs. markets for factors of production) and the Production Possibilities Frontier (PPF).
- Positive vs. Normative Analysis: Positive statements describe the world as it is (testable claims), while normative statements prescribe how the world ought to be (value judgments).
Module 3: Scarcity, Choice & The Production Possibilities Frontier
- Production Possibilities Curve (PPC): Depicts the maximum feasible output combinations of two goods given available resources and technology.
- Law of Increasing Opportunity Cost: The bowed-out shape of the PPF reflecting specialized resources.
- Shifts in PPF: Driven by capital accumulation, technological innovation, and expansion of the labor force.
Module 4: Market Forces of Supply & Demand
- Demand Curve & Law of Demand: Negative relationship between price and quantity demanded; non-price demand shifters (income, price of related goods, consumer tastes, expectations).
- Supply Curve & Law of Supply: Positive relationship between price and quantity supplied; supply determinants (input prices, technology, number of sellers).
- Market Equilibrium: The intersection of supply and demand ($Q_d = Q_s$), market shortages (excess demand), and market surpluses (excess supply).
- Price Elasticity of Demand: Calculating price elasticity using the midpoint method; elastic, inelastic, and unit-elastic demand curves.
Exam Strategy for Scoring Top Marks in ECO1CJ101
To secure top marks in Calicut University semester examinations:
- Draw Clear, Accurately Labeled Diagrams: Ensure every graph includes labels for both axes (Price on the Y-axis, Quantity on the X-axis), equilibrium points ($E_0, E_1$), and directional arrows indicating curve shifts.
- Distinguish Key Terms: Prepare concise 2-mark definitions distinguishing:
- Positive Economics vs. Normative Economics
- Substitute Goods vs. Complementary Goods
- Movement along a curve vs. Shift of a curve
- Accounting Cost vs. Opportunity Cost
- Structure 15-Mark Essay Questions: Begin with the formal law or definition, outline all underlying assumptions, draw the equilibrium graph, present the mathematical or theoretical explanation, and conclude with real-world Indian policy implications.
