ABSTRACT

With the re-election of George Bush, the debate around privatization of Social Security in the United States has been rekindled.  The Republicans favor separating a part of OASDI to be moved into Individual Retirement Accounts. Some have suggested more radical reforms such as moving OASDI entirely from a Defined Benefit (DB) scheme to a Defined Contribution (DC) plan based on the Chilean model.  

Canada has moved to a system of greater pre-funding for the Canada/Quebec Pension Plans (C/QPP) in order to cap contribution rates at 9.9 percent.  These proposals have the goal of creating higher investment returns, to make social security benefits more affordable.   

The important public policy issues inherent in such proposals are numerous: is pre-funded social security demographically immune; does pre-funding social security increase gross national savings and worker productivity;  are there better ways to create a healthy economy;  is social security best offered as a DB or DC plan?  This paper reviews these important issues in the context of recent social security policy initiatives in Canada and the U.S.

After extensive review, the paper concludes that greater pre-funding of social security will not, of and by itself, create a more secure system.
