Economics | Strategic Decisions & Game Theory

About the course

Imagine you and your best friend are deciding between going to a concert or an amusement park for the weekend. The catch? You can’t talk to each other about it. Your enjoyment depends on both of your choices. How do you make your decision? Do you trust your friend to make the same choice as you, or do you try to outsmart each other? 

This simple dilemma introduces us to the intriguing world of game theory. A game, in this context, is any rule-governed situation where the final outcome depends on the actions of more than one person and in today’s complex world, is a basic life skill. The study of game theory has led to numerous breakthroughs in different fields such as economics, political science, and biology. The future applications of game theory are constantly evolving – from improving market efficiency to designing artificial intelligence to understanding social networks, game theory can be seen as a powerful tool for strategic decision making in different fields.

Strategic Decisions and Game Theory is a live interactive course that offers a comprehensive introduction to the principles of game theory and the art of strategic decision-making. You will explore key concepts and important ideas, including ideas of von Neumann, Nash, Schelling and other contemporary economists with real-life illustrations, in this course. You will study how these ideas apply to real-life situations, such as competition among private corporations, conflict among countries and other everyday phenomena like how to play Tic-Tac-Toe and Rock-Paper-Scissors to splitting a restaurant bill and preventing your shoes from getting stolen at your local place of worship.

You will learn basics like types of games, strategies, payoffs and equilibrium behavior and decode the role of information and why who moves when matters in a game. You will deep dive into the ubiquitous nature of game theory and analysis of real scenarios where decisions depend on others’ choices. This would include understanding the role of strategic interactions in shaping our world, especially for global politics, climate change and other similar phenomena. All in all, you will work on a capstone project to apply game theory concepts to a functional or real-world situation.

Get ready to explore the strategies, dilemmas, and surprises that arise when decisions depend on the choices of others. Join us to explore this future-forward course in Game Theory!

“I’ve gained the ability to differentiate between various categories of games—simultaneous versus sequential, zero-sum versus non- zero-sum—and to evaluate them with tools such as payoff matrices, Nash equilibrium, and backward induction. Case studies, including the Prisoner’s Dilemma and the Tragedy of the Commons, have provided me with insights into how strategic conflict and cooperation manifest in contexts ranging from environmental concerns to global diplomacy.”

Programme Details

Week	Lecture Module	Project Module
Week 1	Introduction to game theory Understand the fundamental concepts of game theory and the core ideas of how strategic decision making shapes the world around us. Properties and characteristics of a game Pure & mixed strategy Payoff matrix	History of game theory Differentiate between strategic and non-strategic behaviour by solving problems and analyzing situations. Model different strategic scenarios and various settings as games.
Week 2	Simultaneous & sequential move games Examine two primary types of games and the correlation between timing and outcome. Prisoner’s dilemma Game of chicken First mover vs. second mover	Equilibrium in games Explore suboptimal outcomes in different types of games and examples. Solve elementary simultaneous and sequential games to find equilibrium.
Week 3	Equilibrium behaviour Determine stable outcomes in strategic settings by applying the understanding of equilibrium behavior. Nash equilibrium Subgame perfect Nash equilibrium Competitive vs. cooperative market environments	Strategies of equilibrium ​​Decode notions and assumptions of equilibrium and practice how to find them. Draw connections of equilibrium computation with behavioural economics.
Week 4	Public goods Explore how game theory explains collective action problems, such as the provision of public goods. Tragedy of the commons Societal outcomes Global issues	Implications of public goods Research on what are public goods and common resources. Deconstruct the difficulty to solve these problems and discuss the implications for tackling issues such as pollution and climate change.
Week 5	Counselling:  Get a chance to ask questions to the faculty and the mentor and get their answers and perspective.  You are encouraged to ask questions to the faculty around the following aspects: What are some related fields that can be explored based on this course topic? What are the future trends in the related fields? How can the course learning help the student enhance their college applications?	Mentoring: You are encouraged to ask questions to the mentor around the following aspects: What are some sub-topics to learn/practice beyond the course? What is the scope of the course topic if the student wants to pursue/study it further? What are some personal projects that can be taken up outside of the course based on the knowledge gained in the course?

Capstone Project

As your capstone project, you will be working on a written group assignment that requires taking game theory to the real or fictional world. Throughout the course, you will work on developing ideas that your group can then turn into the final project report. You will achieve this with hands-on practice and by discussing game theory readings. You will learn how to proceed turning specific situations into games and solving them.
