    Plan Design and 401(k) Savings Outcomes
    (2004-03-15) Choi, James J; Laibson, David; Madrian, Brigitte C
    We assess the impact of 401(k) plan design on four different 401(k) savings outcomes: participation in the 401(k) plan, the distribution of employee contribution rates, asset allocation, and cash distributions. We show that plan design can have an important effect on all of these savings outcomes. This suggests an important role for both employers in determining how to structure their 401(k) plans and government regulators in creating institutions that encourage or discourage particular aspects of 401(k) plan design.

    Employee Investment Decisions about Company Stock
    (2003-01-01) Choi, James J; Laibson, David; Madrian, Brigitte C; Metrick, Andrew
    We study the relationship between past returns on a company’s stock and the level of investment in that stock by participants in that firm’s 401(k) plan. Several different decision points are of interest: the initial fraction of savings allocated to company stock, the changes in this fraction, and the reallocations of portfolio holdings across different asset classes. We find that high past returns on company stock do induce participants to allocate more of their new contributions to company stock. By contrast, high company stock have the opposite effect on reallocations of portfolio holdings: high returns produce portfolio shifts away from company stock and into other forms of equity. Overall, for company stock decisions, participants in our sample appear to be momentum investors when making contribution decisions, but they are contrarian investors when making trading decisions.

    $100 Bills on the Sidewalk: Suboptimal Saving in 401(k) Plans
    (2006-01-01) Choi, James J; Laibson, David; Madrian, Brigitte C
    It is typically difficult to determine whether households save optimally. But in some cases, savings incentives are strong enough to imply sharp normative restrictions. We consider employees who receive employer matching contributions in their 401(k) plan and are allowed to make discretionary, penalty-free, in-service withdrawals. For these employees, contributing below the match threshold is a dominated action. Nevertheless, half of employees with these clear-cut incentives do contribute below the match threshold, foregoing matching contributions that average 1.3% of their annual pay. Providing these “undersavers” with specific information about the free lunch they are giving up fails to raise their contribution rates.

    The Importance of Default Options for Retirement Saving Outcomes: Evidence from the United States
    (2006-01-01) Beshears, John; Choi, James J; Laibson, David; Madrian, Brigitte C
    This paper summarizes the empirical evidence on how defaults impact retirement savings outcomes. After outlining the salient features of the various sources of retirement income in the U.S., the paper presents the empirical evidence on how defaults impact retirement savings outcomes at all stages of the savings lifecycle, including savings plan participation, savings rates, asset allocation, and post-retirement savings distributions. The paper then discusses why defaults have such a tremendous impact on savings outcomes. The paper concludes with a discussion of the role of public policy towards retirement saving when defaults matter.

    Reducing the Complexity Costs of 401(k) Participation Through Quick Enrollment™
    (2006-01-01) Choi, James J; Laibson, David; Madrian, Brigitte C
    The complexity of the retirement savings decision may overwhelm employees, encouraging procrastination and reducing 401(k) enrollment rates. We study a low-cost manipulation designed to simplify the 401(k) enrollment process. Employees are given the option to make a Quick Enrollment™ election to enroll in their 401(k) plan at a pre-selected contribution rate and asset allocation. By decoupling the participation decision from the savings rate and asset allocation decisions, the Quick Enrollment™ mechanism simplifies the savings plan decision process. We find that at one company, Quick Enrollment™ tripled 401(k) participation rates among new employees three months after hire. When Quick Enrollment™ was offered to previously hired non-participating employees at two firms, participation increased by 10 to 20 percentage points among those employees affected.

    Defined Contribution Pensions: Plan Rules, Participant Choices, and the Path of Least Resistance
    (2002-01-01) Choi, James J; Laibson, David; Madrian, Brigitte C; Metrick, Andrew
    We assess the impact on savings behavior of several different 401(k) plan features, including automatic enrollment, automatic cash distributions, employer matching provisions, eligibility requirements, investment options, and financial education. We also present new survey evidence on individual savings adequacy. Many of our conclusions are based on an analysis of micro-level administrative data on the 401(k) savings behavior of employees in several large corporations that implemented changes in their 401(k) plan design. Our analysis identifies a key behavioral principle that should partially guide the design of 401(k) plans: employees often follow “the path of least resistance.” For better or for worse, plan administrators can manipulate the path of least resistance to powerfully influence the savings and investment choices of their employees.
