Behavioral economists have been pushing the government to nudge us since some of their own won the Nobel Prize. Like CS Lewis’ “do gooders,” we’ll never be free from their needling and meddling. The latest comes from the Chicago Booth School of Business in an article “Why policy makers should nudge more" by Alex Virkhivker. He wrote,
In one case, the researchers looked at a nudge by the tax-preparation firm H&R Block, which offered clients assistance in filing college financial-aid paperwork, and compared that approach with subsidies and tax incentives offered at the state and federal levels. The nudge produced 1.5 additional college enrollees per $1,000 spent—making it 40 times more effective than the next most effective intervention the researchers analyzed.
Likewise, nudging turned out to be the most cost-effective way of encouraging energy conservation. One program to nudge consumers into lower electricity use, sending letters comparing a household’s energy consumption to that of its neighbors, saved 27 kilowatt-hours per dollar spent. In contrast, a rebate offered by California utility companies produced savings of only 3.4 kWh per dollar, and other demand-management policies that relied on a combination of consumer education and monetary incentives averaged 14 kWh per dollar.
