Understanding the “Law of Diminishing Marginal Utility” with Dr. S. D. Shah
Date: 21st July, 2025 | Venue: Nandkunvarba Mahila College | Audience: FY BBA Students
On 21st July 2025, the Department of Business Administration at Nandkunvarba Mahila College hosted an insightful expert lecture on one of the foundational concepts of Economics — “Law of Diminishing Marginal Utility”. The session was conducted by Dr. S. D. Shah, Assistant Professor, Department of Economics, MKBU. The session was specially organized for the First Year BBA students, aiming to give them a deeper understanding of microeconomic principles with real-life illustrations and conceptual clarity.
Enlightening Introduction to the Law
Dr. Shah began the lecture with a simple yet powerful question: “Why does the satisfaction from each extra chocolate bar decrease after a point?” With this relatable analogy, he introduced the students to the Law of Diminishing Marginal Utility, a principle that states that as a consumer consumes more units of a good or service, the additional satisfaction (marginal utility) from each subsequent unit tends to decrease.
He explained the theory using practical, day-to-day examples such as consumption of food, mobile usage, and entertainment subscriptions. His interactive style, including real-time student participation, made the concept easily understandable for beginners.
Theoretical and Graphical Explanation
To strengthen the students’ theoretical base, Dr. Shah carefully illustrated the utility schedule and graphical representation of marginal utility. The graph — depicting a downward-sloping curve — helped students visualize the decline in satisfaction with every additional unit consumed. He also explained the assumptions behind the law and its limitations, connecting them with consumer behavior and market realities.
Real-World Relevance
What set this lecture apart was the emphasis on practical applications. Dr. Shah emphasized how understanding this law can aid businesses in product pricing, marketing strategies, and consumer psychology. He cited examples from FMCG companies and food chains, explaining how companies design combo offers and limited-time discounts based on utility patterns.
Engaging Q&A and Interaction
The students actively participated throughout the session. Many asked insightful questions, especially related to utility maximization, exceptions to the law, and its relevance in the digital consumption age. Dr. Shah patiently addressed all doubts and encouraged students to explore more real-world economic behaviors through observation and analysis.
Takeaways and Appreciation
The lecture proved to be an eye-opener for many students, making them realize the depth and practical nature of economic theories. The session concluded with a vote of thanks by the faculty coordinator, appreciating Dr. Shah’s dynamic presentation and thoughtful engagement with students.
Conclusion
The expert lecture by Dr. S. D. Shah was not just an academic session, but a valuable experience in connecting textbook economics with real-life consumer behavior. The FY students of Nandkunvarba Mahila College left the room with a richer understanding of how and why human satisfaction changes with consumption — a true testament to the power of economic thinking.
Such expert interactions continue to enrich the learning culture at Nandkunvarba Mahila College, bridging theory with application for the budding minds of tomorrow.
