To evaluate the extent of inefficient behavior in 401(k) pensions, now the dominant form of retirement saving in America, we attribute inefficiencies separately to the employer's menu design versus participant portfolio elections. Results from our analysis of over 1000 plans and a million...

This book posits that retirement security is the central policy concern of our time. A generation of 'Baby Boomers' is on the verge of retirement, yet pension systems confront crushing challenges, and governments often appear confused about which direction they should move in. Contributors to...

Employees are increasingly asked to make sophisticated decisions about their pension and healthcare plans. Yet recent research shows that the decisions 'real' people make are often not those of the careful and well-informed economic agent conventionally portrayed in economic research. Rather,...

We use data on five hundred 401(k) pension plans to evaluate how employer matching incentives influence retirement saving. Company matches prove to have a small effect on participation and saving rates; only one in ten non–highly compensated workers joins the plan because of employer match...

There is reason to believe that technological approaches can help promote voluntary saving in 401(k) retirement accounts. Working with Vanguard, a leading 401(k) plan administrator, we are evaluating the impact of introducing innovations to websites made available to retirement plan...

Target date funds in corporate retirement plans grew from $5B in 2000 to $734B in 2018, partly because federal regulation sanctioned these as default investments in automatic enrollment plans. We show that adopters delegated pension investment decisions to fund managers selected by plan...

Most workers in defined contribution retirement plans are inattentive portfolio managers: only a few engage in any trading at all, and only a tiny minority trades actively. Using a rich new dataset on 1.2 million workers in over 1,500 plans, we find that most 401(k) plan participants are...

Though millions of US workers have 401(k) plans, few studies evaluate participant investment performance. Using data on over 1,000 401(k) plans and their participants, we identify key portfolio investment inefficiencies and attribute them to offered investment menus versus individual portfolio...

Several key lessons for pension design have emerged in the last decade from behavioral economics and finance research. This article analyzes the insights from this literature on how workers decide to save, manage their retirement investments, and draw down their assets in retirement. The aim is...
