WebIt is not hard to see that backward induction always defines a Nash equilibrium. In Fig. 8, it is the strategy combination (High; H: buy, L: don't). A game that evolves over time is better represented by a game tree than using the strategic form. The tree reflects the temporal aspect, and backward induction is succinct and natural.
