Managerial Economics-I Notes
Subject Overview
Managerial Economics-I is BBA's introduction to how core economic principles translate into real business decisions — demand, cost, and market structure, all viewed through a manager's lens. It opens with the foundational tools of managerial economics (opportunity cost, the production possibility curve, incremental and scarcity concepts) before moving into demand analysis, elasticity, and demand forecasting, and closes Unit I with indifference curve analysis and consumer equilibrium. The middle units cover production function theory (isoquants, returns to scale) and cost theory, followed by revenue curves and the four classic market structures — perfect competition, monopoly, monopolistic competition, and oligopoly. The final unit covers pricing practices and factor pricing, including collective bargaining and the basics of capital theory. This is a 6-credit General Elective paper across 4 units, and it lays the groundwork for Managerial Economics-II in Semester 2.

Study guide
This unit introduces managerial economics and demand: its meaning, nature, scope and links with other disciplines, opportunity cost, the production possibility curve, incremental and scarcity concepts, the demand function and its determinants, elasticity, demand estimation and forecasting and indifference curve analysis with consumer equilibrium. Practise elasticity numericals and draw indifference curves with a budget line.
- Production function
- productivity and technology
- short-run and long-run production function
- isoquants
- least-cost combination of inputs
- producer's equilibrium
- returns to scale
- cost concepts and determinants
- short-run and long-run cost theory
Increasing returns
Rises more than in proportion to inputs
Specialisation, economies of scale
Constant returns
Rises in the same proportion
Economies and diseconomies balance
Decreasing returns
Rises less than in proportion
Management difficulties, diseconomies
Study guide
You study production and cost: the production function, productivity and technology, short- and long-run production, isoquants, least-cost combination of inputs, producer's equilibrium, returns to scale and cost concepts and theory. Learn the stages of the law of variable proportions and draw the cost curves.
- Concept and types of revenue
- total/average/marginal revenue and their relationship
- elasticity of demand and revenue
- perfect competition
- monopoly
- monopolistic competition
- collusive and non-collusive oligopoly
- price leadership model
Perfect competition
Very many, identical products
None: price taker
Monopolistic competition
Many, differentiated products
Some
Oligopoly
A few large firms
Interdependent; may collude or follow a leader
Monopoly
One firm, no close substitutes
High: price maker
Study guide
You study revenue (total, average and marginal) and market structures: perfect competition, monopoly, monopolistic competition, collusive and non-collusive oligopoly and the price leadership model. Compare market structures in a table.
- Pricing practices
- commodity pricing and economics of advertisement costs
- demand and supply of factors of production
- collective bargaining
- rent
- profit and interest
- real vs. nominal interest rates
- basic capital theory
- Rent
- Reward for land
- Wages
- Reward for labour
- Interest
- Reward for capital
- Profit
- Reward for entrepreneurship and risk
- Real interest rate
- Nominal rate − inflation
Study guide
The last unit covers pricing practices, commodity pricing and the economics of advertising costs, demand and supply of factors of production, collective bargaining, rent, profit and interest, real versus nominal interest rates and basic capital theory. Be able to explain the theories of rent and profit briefly.
Why Managerial Economics-I Matters
Understanding demand, cost and market structure is essential for pricing, marketing and strategy decisions, and economics is a core part of MBA entrance and civil service preparation.
How to Prepare for Managerial Economics-I
- Practise drawing and labelling curves; diagrams earn marks.
- Solve elasticity and cost numericals with formulas written out.
- Compare the four market structures in one table.
Managerial Economics-I: Frequently Asked Questions
What is the law of demand?
The law of demand states that, other things being equal, the quantity demanded of a good falls as its price rises and rises as its price falls.
What is the difference between short run and long run?
In the short run at least one factor of production is fixed, while in the long run all factors can be varied.
