The most recent entry was a report by the Urban Institute which simulated the short- and long-term effect of three policy options for “flattening tax incentives and increasing retirement savings for low- and middle-income workers.” The report concluded that “reducing 401(k) contribution limits increases taxes for high-income taxpayers; expanding the saver’s credit raises saving incentives and lowers taxes for low- and middle-income taxpayers; and replacing the exclusion for retirement saving contributions with a 25 percent refundable credit benefits primarily low- and middle-income taxpayers, and raises taxes and reduces retirement assets for high-income taxpayers.”
However, and to the authors’ credit, the report also noted that “the behavioral responses by both employers and employees will affect the final savings outcomes achieved under reform but are beyond the scope of our estimates[i].”
In previous posts, we’ve highlighted the dangers attendant with relying on simplistic retirement modeling assumptions, the application of dated plan design information to future accumulations, and the choice of adequacy thresholds that, while mathematically accurate, seem unlikely to provide a retirement lifestyle that would, in reality, feel “adequate.”
However, one of the more pervasive assumptions, particularly when it comes to modeling the impact of policy and/or tax reform changes, is that, regardless of the size and scope of the changes proposed, workers – and employers – will generally continue to do what they are currently doing, and at the current rate(s), for both contributions and/or plan offerings. Consequently, there is talk of restricting participant access to their retirement savings until retirement, with little if any discussion as to how that might affect future contribution levels, by both workers and employers, and there are debate about modifying retirement plan tax preferences as though those changes would have no impact at all on the calculus of those making decisions to offer and support these programs with matching contributions. Ultimately, these behavioral responses might not only impact the projected budget “savings” associated with the proposals, but the retirement savings accumulations themselves.
EBRI research has previously been able to leverage its extensive databases and survey data (including the long-running Retirement Confidence Survey) to both capture potential responses to these types of proposals and, more significantly, to quantify their potential impact on retirement security today and over the extended time periods over which their influence extends. In recent months, that research has provided insights on the full breadth of:
- A retirement savings cap[ii],
- The proportionality of savings account balances with incomes[iii], and
- The impact of permanently modifying the exclusion of employer and employee contributions for retirement savings from taxable income, among other proposals[iv].

Additionally, the behavioral responses by both employers and employees will affect the final savings outcomes achieved under reform but are beyond the scope of our estimates. For instance, employees may save more in response to improved incentives, in which case the benefits to low lifetime income households would be greater than we find. On the other hand, employers might reduce their contributions in response to some of the policy changes outlined. In this case, the tax and savings benefits we find would be overstated. While our policy simulations are illustrative, addressing these behavioral responses would be a chief concern in tailoring specific policies to create the best incentives.”
