The Power of Suggestion: Inertia in 401(k) Participation and Savings Behavior.

Madrian & Shea (2001)
Summary by 
Mark Egan

This default savings program automatically enrolled employees into a 401(k) plan, finding that the default was incredibly sticky both in terms of how many people did not opt out of it & how many people stuck with the automatic savings rate. The latter issue, potentially problematic if people did not save enough, was later tackled by ‘Save More Tomorrow’.
