"Value of time" is often employed by utilitarians. It can be hard to determine one's value of time for a variety of reasons. This talk will be about different currencies of personal life like time, money, and pleasure; and how choices are implicit trades between them. The talk will focus on when it's appropriate to treat these resources as liquid currencies and when it's not. After discussing the theory, and some examples, we'll practice. We'll individually come up with our own exchange rates for personal currencies, then fix one another's estimates in small groups. I hope everyone walks away from this talk with a concrete number for their value of time. The meetup is at a KTH academic building and the room is on the 5th floor, two stairs up.
