Defined Contribution Pensions: Plan Rules, Participant Decisions, and the Path of Least Resistance

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.

Employee Investment Decisions about Company Stock

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

Split or Steal? Cooperative Behavior When the Stakes Are Large

We examine cooperative behavior when large sums of money are at stake, using data from the television game show Golden Balls. At the end of each episode, contestants play a variant on the classic prisoner's dilemma for large and widely ranging stakes averaging over $20,000. Cooperation is surprisingly high for amounts that would normally be considered consequential but look tiny in their current context, what we call a “big peanuts” phenomenon. Utilizing the prior interaction among contestants, we find evidence that people have reciprocal preferences. Surprisingly, there is little support for conditional cooperation in our sample. That is, players do not seem to be more likely to cooperate if their opponent might be expected to cooperate. Further, we replicate earlier findings that males are less cooperative than females, but this gender effect reverses for older contestants because men become increasingly cooperative as their age increases
