... we exploit two discontinuities in the age cuto↵s of receiving such a letter to study their e↵ects on private retirement savings. Our results show that the letters increase private retirement savings. The e↵ects are fairly sizable and persistent over several years.

Moreover, we present evidence suggesting that both information and salience drive the savings e↵ect. Our paper adds to a recent literature showing that policies that go beyond the traditional neoclassical reasoning can be powerful to increase savings rates. JEL Classification: H55, H24, J26, D14
