A friend of mine received three prestigious academic awards in the same year. I asked him, “Wouldn’t you have been happier getting them in separate years? After all, the marginal utility of an award probably is decreasing within a particular period of time. So wouldn’t getting these awards in separate years have increased your lifetime utility?”
He said that my observation was probably correct. However, he was so surprised to receive even one of them, and the increase in his happiness was so great, that he just wasn’t able to think in this narrow economic way. I guess there are occasions (probably very few!) where even simple economics isn’t 100 percent relevant.
