We know that people tend to reject deals which they see as grossly unfair. This is most apparent in the classic economic experiment of the ultimatum game.
In this game, two players are given a pot of money to share. One player is randomly chosen. She can propose any a split for herself and for the other player. The second player can then reject the deal outright, in which case both players get nothing, or can accept the deal, in which case both players get what the first player proposed. Critically, there is no second deal. There is no Shadow of the Future notion of reciprocity of retribution. This game has been played thousands of times, across cultures. The consistent finding is that deals where the second player gets less than 20% of the pot are consistently rejected...although the second player is worse off in rejecting the deal outright.
The common interpretation of this game is that this dents the neo-classical notion of homo economicus. This is just wrong. The Economist article makes this error, quite surprising because the Economist is usually sympathetic to neo-classical notions. Neo-classical utility maximization theory easily accommodates this behaviour. The theory is framed in terms of maximizing utility rather than income for a very good reason. All you need to believe is that utility is a function of relative income as well as absolute income. The second player in the ultimatum game is maximizing utility, not income. He is happier saying no to a deal which feels wrong.
Under this interpretation the great neo-classical results, like Ronald Coase's insight into free agents negotiating their way to a Pareto-optimal outcomes, are totally valid. The ultimatum game does not create a case for governmental/ authoritarian meddling in people lives or in the economy generally.
What the ultimatum game does offer a really useful insight into is not economics, but politics. Why does income distribution so dominate political discourse? Why is unequal income distribution even though of as "unfair"? It seems to be a pattern of thought that is hard-wired into us as a species.
This is not a normative point; more equal outcomes in a society is not better or worse in a moral sense. My own take is that equality is simply irrelevant from a moral or normative viewpoint. This is just a positivist point. Privilege is naturally resented in every social group: cricket team, company or nation state. More so if it is seen as unearned, inaccessible or both. Finding ways to address or harness that resentment in a creative way is a necessary part of any polity. This is a managerial task...not a moral task.
There are some interesting puzzles that this view might help answer.
For instance, why to the janitors employed by Goldman Sachs earn more than the janitors employed by the municipal government? Both sets of janitors are equally skilled and productive. This is a commonly observed phenomenon. Most companies that pay well do so across job families or skill levels. Are companies trying to address that political problem thrown into sharp relief by the ultimatum game? I can just hear the Goldman janitor cribbing to his mates at the pub "I work for Goldman. The guy with a funny nose also works for Goldman. Why does he make 100 times what I make? How is that fair?". The guy with the funny nose might have a Ph.D. or an ivy league degree...but that sense of grievance is going to be out there anyway.
This may be the reason outsourcing often reduces costs even when working within the same labour pool. Changing the badge on the janitor's uniform breaks that limbic sense of connection between the janitor and the Ph.D. guy with the funny nose. Breaking that limbic connection makes the inequality easier to swallow.
A much more speculative and flaky line of argument...but what the hell...I've been drinking some Chardonnay from Burgundy...
This view might also talk to why third world countries find it hard to trade with the first world. As an Indian, I find it weirdly easy to understand the emotional heft of this argument.
India has done spectacularly well since opening up to the world economy in 1991. Yet, despite this success, political commitment to trade or free-market principles is really thin. Why? Because an Indian negotiating with an American is still talking to someone about 25 times richer than him. He is likely to come away from that negotiation feeling screwed, regardless of the objective outcome of the negotiation. I grew up in Indira Gandhi's India when we were trying to promote South-South co-operation. Meaning...we liked dealing with other poor countries more than we liked dealing with rich countries. This is self-destructive. India still badly needs the income that trade brings and the gains from trade are greater between dissimilar countries or agents. But at some visceral level, this all makes sense.
