Anything Can Happen!

Introduces a counter-intuitive concept in game theory that 'anything can happen' in repeated games.

Caption Ever heard of the Folk Theorem? 🤔 In repeated games, if players are patient enough, literally ANY outcome can be sustained. Mind blown! #GameTheory #FolkTheorem #Economics

Why 'Folk' Theorem?

Explains the unusual and intriguing origin of the theorem's name, appealing to curiosity.

Caption 'Folk Theorem'? What's in a name? 🧐 Discover the surprising history behind this game theory concept – it's not what you think! #GameTheoryFacts #EconomicsHistory #FolkWisdom

The Payoff Problem

Highlights a common misconception about calculating payoffs in repeated games and introduces the need for normalization.

Caption Why do payoffs get 'really, really big' in repeated games? 🤯 The secret is in the normalization! Learn how we truly measure average payoffs. #GameTheoryExplained #EconomicsLesson #Payoffs

Average Payoffs Explained

Introduces the crucial concept of average discounted payoffs and the mathematical adjustment needed.

Caption Forget summing payoffs! 🤯 We're switching to average discounted payoffs to make sense of repeated games. Here's the magic formula! ✨ #GameTheory #DiscountFactor #AveragePayoff

The Magic of 1 Minus Delta

Explains the mathematical intuition behind the 1 minus delta normalization, clarifying a potentially confusing concept.

Caption Ever wonder why we multiply by (1 - delta) for average payoffs? 🤔 It's not magic, it's math! Unpack the normalization secret here. #Economics #GameTheoryTips #MathExplained

What's a Feasible Payoff?

Visually explains the concept of the 'feasible set' of payoffs in a game, making abstract concepts concrete.

Caption Can you get *any* payoff in the Prisoner's Dilemma? 🤯 Not quite! Discover the 'feasible set' and why your average payoff must live there. #PrisonersDilemma #GameTheoryVisuals #Economics101
