NUDGE by Richard H.Thaler and Cass R. Susteinは結構面白い本で、小説と異なり余り難しい単語は出てこないのですが、読んでいると自分の身の回りではどうだろうかと考える内容が多いので読む速さは遅くなっているようです。
According to economic theory (and simple logic), money is "fungible," meaning that it doesn't come with labels. Twenty dollars in the rent jar can buy just as much food as the same amount in the food jar. But households adopt mental accounting schemes that violate fungibility for the same reason that organizations do: to control spending. Most organizations have budgets for various activities, and anyone who has ever worked in such an organization has experienced the frustration of not being able to make an important purchase because the relevant account is already depleted.
経済を勉強した人なら上の最初の文に出てくる "money is "fungible" の意味は直ぐ分かるのでしょうが、私は理科系だったので経済の勉強はした事がないので分かりません。但し、上の文の前に、ある人が、幾つもの "mason jar" に "rent" とか "food" とラベルを貼り、その中にそれぞれに割り当てたお金を入れて家計を管理する逸話があったので、ここは、お金には、家賃とか食料とかのラベルはついていないと言う意味になると理解しました。 辞書で "fungible" の意味を調べます。
