Does gift-giving make sense? Silly question

It’s the season of the year when the bylaws of the economists’ union require me to issue the stern admonition that the medieval practice of gift-giving should cease and desist forthwith. And the fact that I’m a bit late won’t stop me.

Perhaps more people - recipients of socks and handkerchiefs and other wondrous surprises - will be receptive to the profession’s utterly disinterested (look it up) advice and see the wisdom of my words.

Gift-giving is an irrational act, one where sentiment and emotion triumph over good sense. Since it’s hardly possible for the giftor better to know what the giftee would like to be given than the giftee themself, the success rate of the practice is abysmally low.

So low, in fact, as to justify economists using one of their worst pejoratives to brand the practice as involving a “deadweight loss” – one where the benefit to the giver and the benefit to the receiver are insufficient to justify the cost of the transaction, thereby creating a loss to the community.

(And please, please don’t ruin my Boxing Day by arguing that the commercialisation of Christmas at least creates jobs. The economists’ union’s Christmastide message is that any mug can create jobs, all you have to do is spend money – your own or someone else’s. The whole point of economics is to help the community spend money in ways that yield it greater benefit than other ways.)

But fear not. Go back to eating your leftovers in peace (and goodwill). I’m not actually a member of the economists’ union, but an adherent to a dissident sect known as behavioural economists (people who, too late in life, realised psychology made more sense than economics).

This bunch of heretics delights in pointing to the glaring weaknesses in the oversimplified model conventional economists carry in their heads.

But you need only to have gone to Sunday school to see the weakness in all the nonsense about the deadweight loss of Christmas. I think it was the little chap himself who said it was more blessed to give than receive.

And there is, in fact, plenty of what a deranged economist would call “giver’s surplus”. How do I know? Because psychological experiments have demonstrated it – many of them conducted by Professor Elizabeth Dunn, a psychologist at the University of British Columbia.

But just last week came new research by Ed O’Brien, of the University of Chicago Booth School of Business, and Samantha Kassirer, of Northwestern University Kellogg School of Management, showing that “the joy of giving lasts longer than the joy of getting”.

One of the great limitations of human nature is “hedonic adaptation”. The happiness we feel after a particular activity or event diminishes each time it’s repeated. It’s likely this phenomenon is “adaptive” – we’ve evolved to react that way because it increases our ability to survive and reproduce; it keeps us striving.

But the researchers find that giving to others may be an exception to the rule. In two studies they found that participants’ happiness did not decline, or declined more slowly, if they repeatedly bestowed gifts on others versus repeatedly receiving those same gifts themselves.

Separate research by Dr Vera te Velde, a lecturer in economics at the University of Queensland, has found evidence for the existence of “beliefs-based altruism” – concern about other people’s emotions and other psychological experiences, beyond any material measure of their wellbeing.

This means “we don’t give gifts only because we want people to have something that they want; we also give gifts because we want them to feel cared about, experience joy or a pleasant surprise when receiving it. Or to prevent them from feeling disappointed if we fail to give anything,” she says.

This kind of altruism can apply in many other situations. “When girl guides come to our doors to sell cookies, we buy them not only to support the group and because we like cookies, but also because we want the girls to feel successful and valued,” she says.

But how can we be sure that a pure concern for others’ feelings is the motivation for these behaviours, instead of – or maybe, as well as – concern about our own reputations? After all, I may not only want girl guides to feel good, I may also want to be known as someone who supports them.

To help answer this question Velde experimented with a sharing game. One person is asked to share $10 with another person. But the bank handling the transfer occasionally makes a mistake and transfers exactly $1 to the other person. So if that person receives $1, they don’t know if it’s a bank mistake or the first person’s selfishness.

Asked whether they thought the recipients would prefer to know about giver’s true intentions, many participants thought they would. Even so, when they played the game themselves, the participants were more likely to give either exactly $1 (thereby hiding their selfishness) or exactly $5 (thereby revealing themselves to be perfectly fair).

But get this: even the people who tried to hide their selfishness were demonstrating their concern about the emotions of the other person. Economics makes a lot more sense with a bit of psychology thrown in.
