Description: On July 1 1997, a new privatized but compulsory retirement system came into effect in Mexico. The new system has a complex web of contributions by employers, employees and by the government. The retirement funds also have a complex web of charges applied to the funds. This paper carefully analyzes these complex cases to find out which funds perform the best. It shows through simulations that the optimal strategy for individual retirement account holder is not to stay with one fund throughout the working life. Instead, the best option is to switch at some point. The switching point depends on a number of factors: 1. the wage rate of the workers [and also on the growth rate of wages], 2. the real interest rate, and 3. the inflation rate.

Description: This study examines the relationship between the administrator of a pension plan [the principal] and the actuary [the agent]. The objective is to design a contract for both the plan administrator and the actuary so that the actuary provides the appropriate level of information to the plan administrator. The study uses a simple model- one principal [the pension fund administrator] and one agent [the actuary] in a one-period model. In standard principal-agent models, working harder means higher productive output. In this model, it means more accurate information. From Actuarial Research Clearing House 1999 Vol. 1.

Description: This paper is about the looming pension crisis in Canada. Falling pension coverage, poor quality of coverage, and the shift from defined benefit plans to defined contribution plans suggest that there will still be a strong dependency on Government, but government programs are also in a weak position largely due to the well documented phenomenon of an aging population.
