The Pension Research Council of The Wharton School of the University of Pennsylvania has done a study on the effects of Utah’s change in its pension system. Before the change, employees participated in a defined benefit plan. Employees hired after the change were given a choice between a hybrid (defined benefit/defined contribution) plan or a straight defined contribution plan. Those who failed to make a choice were automatically assigned to the hybrid plan. In general, either of the new plans was less generous than the old defined benefit plan.
In general, the Pension Research Council found that employees hired after the change had greater turnover than those hired before the change. Moreover, those electing into the hybrid plan were more likely to stay with the employer than those electing into the defined contribution plan. Those who defaulted into the hybrid plan had the highest turnover.
The Pension Research Council concluded that while the change may have saved the state money in pension costs, “public pension reformers must consider employee responses, in addition to potential cost savings, when developing and enacting major pension plan changes.”
