Description: Concomitant with the industrial revolution, the function of providing old age income shifted from families and local institutions to government social security and private pension plans. The history of this change in the U.K. and U.S. is reviewed. A simple mathematical model provides insights into the role played by three rates [the rate of increase of the working population, the time preference rate, and the rate of real wage growth] in determining optimum funding policy.

Description: The decline of importance of private defined benefit plans in relation to defined contribution plans in the United States is a major issue of interest to pension actuaries. This decline is undeniable, and has been attributed to numerous factors: costs of government regulation, societal and cultural changes, changed attitudes of employers, and employees' lack of understanding of defined benefit plans. It has also caused some to proclaim the end of a private defined benefit plan. This work analyzes possible macroeconomic factors contributing to the crisis of defined benefit plans, and proposes an alternative hypothesis for the cause of the crisis: the decline of relative attractiveness of defined benefit plans in relation to defined contribution plans due to the shift in the way relative returns to macroeconomic factors of production, i.e., capital and labor, are allocated in the national economy. Possibilities of improvement of the position of defined benefit plans are also discussed. From Actuarial Research Clearing House 1998 Vol. 2.
