In this love song in Once, “Guy” sings to “Girl”. He wouldn’t trade her for gold. He also discusses what would happen if “your life were gold” with the question, “how long do you think you’d stay living?” This song presents nice examples of tradeoffs, but where it really adds a unique voice is to the field of health economics or how an economist analyzes the value of a life. People do make choices daily that increase the probability of accidents/deaths. From that, economists can calculate the value of a life.
