There is a project for which player 1 can exert effort e 20 that costs her c(e) = 0.5e2. If player 1 and player 2 can come to an agreement, then a total value of v(e) = e is produced, which can be allocated between the two players. Effort also produces a value y(e) = ke, where k = [0, 1], that player 1 can obtain for herself if player 1 and 2 fail to agree. The game has three stages: (I stage) Player 1 chooses effort e 2 0; (II Stage) Player 2 observes e and chooses and effort level a € [0, 1]; (III stage) Player 1 observes a and either agrees (a) or rejects (r) the offer. If player 1 accepts the offer, then her payoff is ae - 0.5e² and player 2's payoff (1-a)e. If she rejects the offer, then player 1's payoff is ke - 0.5e² and player 2's payoff is zero. What is the subgame perfect equilibrium effort choice?

Question
4. There is a project for which player 1 can exert effort e > 0 that costs her c(e) = 0.5e2. If player 1 and
player 2 can come to an agreement, then a total value of v(e) = e is produced, which can be allocated
between the two players. Effort also produces a value y(e) = ke, where k = [0, 1], that player 1 can
obtain for herself if player 1 and 2 fail to agree. The game has three stages: (I stage) Player 1 chooses
effort e > 0; (II Stage) Player 2 observes e and chooses and effort level a € [0, 1]; (III stage) Player 1
observes a and either agrees (a) or rejects (r) the offer. If player 1 accepts the offer, then her payoff is
ae - 0.5e² and player 2's payoff (1-a)e. If she rejects the offer, then player 1's payoff is ke - 0.5e²
and player 2's payoff is zero.
