+* in the second panel that for $t \geq 1$  the **reborn at $t$** Stackelberg leader wants to increase the output of the follower firm 2 below that prescribed by the time $0$ Stackelberg leader

+Taken together, these outcomes express the time inconsistency of the original time $0$ Stackelberg leaders's plan.
