    Cool I play poker but never heard about the `Shapley value. Seems great if you want to have a business with employees working for you. Thanks for the new insights!

    Cookies riddle has actually not sufficient incomng data. We know what my and my friend's separate productivity is, but our productivity in a streamline model is not given. We can solve it the way shown in the video only if we cook separately

    @8:55 Game theory doesn't tell you how to be fair. I assume an economist wrote a line that absurd. Fairness is a perception (about which there are decades of research), and this approach barely skims the surface of only one facet of perceptions of fairness.

    I have to tell you, the PD is a cooperative game. The game is variable-sum, not zero-sum; everyone benifits from cooperation.

    It sounds like the Kyoto protocol was aiming for the Shapley equilibrium, but ended up in a prisoner's dilemma lol. Thanks for the video, very clear and concise.

    Actually cooperative games exist when there is an authority that can enforce contracts effectively, thus enforcing cooperative strategies. In non cooperative games there is no effective authority that enforces contracts, thus coalitions exist only as far as they are convenient or enforcible by the players themselves. You are confusing concepts of cooperative games with zero sum games. In zero sum games what you win was lost by another player. In non zero sum games you have to consider the creation and destruction of value within tne game. Different concepts.

    By that logic, you cannot play a game by yourself. But there are tons of games that make you play against a "system". Most computer games are, for starters, and most cooperative games can be played by yourself
