An employer wants to hire you and can offer you either a high or low salary, which you can either accept or reject. You can maximize your payoff by:

$-$ ?credibly committing to rejecting a low offer before the employer makes an offer.

$-$ ?rejecting the offer, because it will be low.

$-$ ?accepting the offer, even though it will be low.

$-$ ?accepting the offer, which will be high.
