Here are some details of a study reported in an article in The Economist magazine:
Paradoxically, as the share of the population that receives benefits in a given area rises, support for welfare in the area falls. A new NBER paper finds evidence for an even more intriguing and provocative hypothesis. Its authors note that those near but not at the bottom of the income distribution are often deeply ambivalent about greater redistribution.This is an almost classic case of "cutting your nose off to spite your face" except here the poor opposing aid are getting a benefit. A meagre one. But something of value to them. They can be smug in the distance between their own poverty and that of those who they are pushing down further into poverty.
Economists have usually explained poor people’s counter-intuitive disdain for something that might make them better off by invoking income mobility. Joe the Plumber might not be making enough to be affected by proposed hikes in tax rates on those making more than $250,000 a year, they argue, but he hopes some day to be one of them. This theory explains some cross-country differences, but it would also predict increased support for redistribution as income inequality widens. Yet the opposite has happened in America, Britain and other rich countries where inequality has risen over the past 30 years.
Instead of opposing redistribution because people expect to make it to the top of the economic ladder, the authors of the new paper argue that people don’t like to be at the bottom. One paradoxical consequence of this “last-place aversion” is that some poor people may be vociferously opposed to the kinds of policies that would actually raise their own income a bit but that might also push those who are poorer than them into comparable or higher positions. The authors ran a series of experiments where students were randomly allotted sums of money, separated by $1, and informed about the “income distribution” that resulted. They were then given another $2, which they could give either to the person directly above or below them in the distribution.
In keeping with the notion of “last-place aversion”, the people who were a spot away from the bottom were the most likely to give the money to the person above them: rewarding the “rich” but ensuring that someone remained poorer than themselves. Those not at risk of becoming the poorest did not seem to mind falling a notch in the distribution of income nearly as much. This idea is backed up by survey data from America collected by Pew, a polling company: those who earned just a bit more than the minimum wage were the most resistant to increasing it.
Poverty may be miserable. But being able to feel a bit better-off than someone else makes it a bit more bearable.
