Description: The paper reviews the demographic shifts, including improved life expectancy and the baby-boom/baby-bust cycle, of the past half-century and discusses their impact on the funding of pay-as-you-go paygo social security systems. From Transactions of Society of Actuaries 1995, Vol. 47.

Description: There is growing evidence of a positive correlation between income levels and longevity. In short, high-income earners live longer. That also means that high-income earners get larger retirement-income security benefits from Social Security. This correlation raises a number of questions: if Social Security contributions are a level percentage of earnings, and high-income earners live longer and receive larger Social Security benefits, then is Social Security regressive? If higher-income actually causes enhanced longevity, then would providing more Social Security benefits enhance population life expectancy? This paper analyzes both the OASDI system of the United States and the Canada/Quebec Pension Plans in Canada to see if these systems are 'a good deal' and whether they are regressive or progressive as defined above.

Description: This paper reviews and compares the Canadian and U.S. Social Security systems as to their adequacy, actuarial equity and progressiveness. It concludes that the Canadian system[s] provide larger minimum benefits and, thus, greater adequacy than the U. S. On the other hand, the analysis indicates more emphasis on actuarial equity in the U.S. system [in total] than in Canada. Finally, both systems are shown to be highly progressive in that lower-wage earners get larger benefits per dollar of contribution than do higher wage earners. The paper concludes by noting that while the systems in these two countries have remarkably different actuarial formulae for determining benefits, and remarkably different structures, that the benefits that result from the two systems are surprisingly similar.
