Nina: Microeconomics Masterclass: From Preferences to Monopoly Power — Full Theory + Exam Tricks

Описание: Welcome to the ultimate microeconomics lesson.
In 90 minutes, we travel from consumer preferences to utility maximization, income & substitution effects, cost minimization, competitive supply, monopoly MR=MC secrets, Lerner index intuition, Cournot & Stackelberg games, Bertrand paradox, and cartel instability.

This is not a passive lecture — it’s a full micro theory masterclass built for:
✔ University students (LSE, HSE, AP Micro, IB HL)
✔ Anyone preparing for midterms, finals, EC1002, or competitive exams
✔ Learners wanting the secrets behind exam tricks and diagrams

🔍 What you will learn:
• How to interpret indifference curves correctly (including odd cases like upward-sloping ICs)
• How to solve utility maximization problems fast (Cobb-Douglas shortcuts, corner solutions)
• How to break every price change into substitution & income effects
• The logic of SR vs LR cost curves, shutdown rules, and supply
• Why monopolies choose MR = MC and never produce on inelastic demand
• How oligopolies behave: Cournot best responses, Stackelberg advantage, Bertrand price wars
• Why cartels collapse (game theory explained simply)
