Christmas is not the most wonderful time of the year for economists. The holiday spirit is puzzlingly difficult to model: It plays havoc with the notion of rational utility-maximization. There’s so much waste! Price-insensitive travelers pack airports beyond capacity on Dec. 24 only to leave planes empty on Christmas Day. Even worse are the gifts, which represent an abandonment of our efficient system of monetary exchange in favor of a semi-barbaric form of bartering.
Still, even the most rational and Scroogey of economists must concede that gift-giving is clearly here to stay. What’s needed is a bit of advice: What can economics tell us about efficient gifting so that your loved ones get the most bang for your buck?
