Wicksteed’s blanket The theologian and economist Philip Wicksteed offers the following observation: “[We] lie awake (or what we call awake next morning) half the night consciously suffering from cold, when even without getting out of bed we could reach a blanket or a rug which would secure comfortable sleep for the rest of the night.” Suppose that stay ing in a freezing bed gives Wicksteed 1 utile now (t 5 0), 1 utile in the middle of the night (t 5 1), and 1 utile in the early morning (t 5 2). If he reached for the blanket, he would suffer 0 utiles now but enjoy 5 utiles in the mid dle of the night and in the early morning. A patient man, Wicksteed might have had a delta of one. What is his beta, given that he does not reach for the blanket?
