Almost 50 million Americans are burdened by the need to repay almost $2 trillion in student loan debt, while at the same time having to save for retirement. This article analyzes the potential impact of the 2022 SECURE 2.0 Act reform which permits employers to match contributions for student...

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...

For decades, households' subjective expectations elicited via surveys have been considered meaningless because they often differ substantially from the forecasts of professionals and ex-post realizations.
