Past Paper On Economics Of Industry For Revision
Economics of Industry (also known as Industrial Organization) moves beyond the perfect competition models of basic microeconomics to look at the “real world” of imperfect markets. This course focuses on how firms set prices, differentiate their products, and strategically interact to gain market power. Whether you are analyzing a global tech monopoly or a local oligopoly, this subject provides the tools to understand Structure, Conduct, and Performance (SCP).

To help you dominate your finals, we have synthesized the most frequent “strategic-level” questions found in recent Industrial Economics past papers.Economics of Industry: Key Revision Q&A.
Q1: What is the “Structure-Conduct-Performance” (SCP) Paradigm?
A: This is the foundational framework of the subject:
-
Structure: Market conditions (e.g., number of sellers, barriers to entry).
-
Conduct: Behavior of firms (e.g., pricing strategies, R&D, advertising).
-
Performance: Efficiency and profitability of the industry.
The theory suggests that market structure determines the conduct of firms, which in turn determines the performance of the industry.
Q2: Compare the Cournot, Bertrand, and Stackelberg Models of Oligopoly.
A: These models describe how a few large firms compete:
-
Cournot: Firms compete on Quantity. They choose their output simultaneously, assuming the rival’s output is fixed.
-
Bertrand: Firms compete on Price. In a simple model with identical products, this leads to the “Bertrand Paradox” where price equals marginal cost ($P = MC$).
-
Stackelberg: A “Leader-Follower” model where one firm chooses its quantity first, and the other reacts.
Q3: What are “Barriers to Entry” and how do they sustain Monopoly power?
A: Barriers prevent new firms from entering a profitable industry. They can be:
-
Structural: Economies of scale, high sunk costs (e.g., building a rail network).
-
Strategic: Limit pricing (setting prices low to deter entry) or heavy brand advertising.
-
Statutory: Patents, copyrights, or government licenses.
Q4: Explain “Price Discrimination” and its three degrees.
A: This occurs when a firm charges different prices for the same product to different consumers:
-
First Degree: Charging every consumer their exact maximum willingness to pay (removes all consumer surplus).
-
Second Degree: Charging based on quantity consumed (e.g., bulk discounts).
-
Third Degree: Charging different prices to different groups (e.g., student vs. adult cinema tickets).
Q5: What is “Horizontal” vs. “Vertical” Integration?
A: * Horizontal: A firm merges with or acquires a competitor in the same stage of production (e.g., two airlines merging).
-
Vertical: A firm moves into a different stage of the supply chain. This can be Backward (buying a supplier) or Forward (buying a retail outlet).
Why Practice with Economics of Industry Past Papers?
Industrial Economics exams are heavily focused on Game Theory and Numerical Equilibrium Problems. You will likely be asked to “Calculate the Nash Equilibrium for two firms in a payoff matrix” or “Determine the Herfindahl-Hirschman Index (HHI) for a specific industry.”
By practicing with our past papers, you will:
-
Master the Math: Practice calculating the Lerner Index to measure a firm’s market power.
-
Analyze Concentration: Get fast at calculating Concentration Ratios ($CR_4$ or $CR_8$) to define market types.
-
Evaluate Antitrust Policy: Practice arguing the pros and cons of government intervention in “Natural Monopolies.”
