Assume that you assign no cost to your time (oth when mentioned explicitly in the scenarios). Scenario A: You can immediately give the guitar to your brother who has agreed to pa $650. 13A. Reservation price under Scenario A: Scenario B: You can leave the guitar on Craigslist. If you do this, you think there is a 10 you get a full price offer within the next month and a 20% chance that you get a non- negotiable offer of $750. There is a 70% chance that you get no more offers and that up selling to your brother for $650. No matter what happens, if you choose this option spend extra time and hassle worth, say, -$50 to you. (The option in Scenario A is also a to you.) 13B. Reservation price under Scenario B
