Thanks to David Thiessen for sending this article in.
I have not read Joel’s original work. However, after reading the article, I think he misses the point. Other than consumer surplus, the acts of gift exchanges carry sentimental (intangible) premiums, or sociologists call them social credits, that can’t be observed in individual transactions. Social credits are accumulated over time, not from any isolated incidents.
To test the hypothesis, try not giving away Christmas presents to your in-laws this year and explain to them that “your gift is a waste of resources, according to Joel Waldfogel.”
