There is a new study out that chronicles some of the obstacles to pension reform and lists what states have done in the period 2010-13 for various aspects of reform. These include increases to employee contribution rates, decreases to COLAs, reduction to multipliers, increases in retirement age, prohibiting spiking, and switching to defined contribution plans. Interestingly Pennsylvania is listed as having made no changes on any of these aspects, even though a 2010 law did make some changes for new hires in the two statewide systems.
