When Congress passed the Pension Protection Act of 2006, paving the way for greater use of auto-enrollment in 401(k) plans, lawmakers rationalized the landmark policy largely on the work of a few economists.

One was Richard Thaler, the recent recipient for the Nobel Prize in Economics based on his research on behavioral economics, who first began writing about automatic enrollment and escalation in 401(k)s in 1994.

On Twitter this week, the Nobel laureate staked out an unpopular position on the question of whether Congress should limit pre-tax contributions to 401(k)s as a part of tax reform.
