I review the academic literature on defined contribution retirement plan design and participant behavior. While adoption of automatic enrollment has significantly increased participation rates, recent studies find the long-run effects on savings are smaller than the short-run effects, with some...

This paper suggests that the nature of the funding of defined benefit pension plans may be an important reason why personal saving has not responded positively to the high real interest rites and tax incentives to encourage saving and investment of the last few years. From a firm's standpoint,...
