    A computational investigation of optimal parameters in pension reform
    (2000) Kiraci, Arzdar
    The purpose of this dissertation is to develop a computational framework to identify a set of parametric reform options to rehabilitate publicly run, pay-as-you-go-based pension systems under alternative strategies for reform involving once-and-for-all as well as gradual changes in pension parameters. The techniques developed are applied to the Turkish pension system, which is particularly interesting as it already faces a severe financial crisis despite a relatively young population. The results confirm the need for urgent reform.

    A genetic algorithm-based search for parametric reform alternatives for the Turkish pension system : 2005-2060
    (2005) Alparslan, Mustafa Artun
    In this thesis, we search for parametric reform alternatives so as to achieve a balance in the long term accumulated difference between pension expenditures and revenues of the SSI, the largest pension fund in Turkey, from 2005 to 2060. The projected worker-retiree composition of the pension system is allowed to change along with proposed policy changes in contribution and replacement rates. These changes in population structure are modeled by estimated work and pension income elasticities of labor supply values so that the resulting changes in the incomes of the worker could now affect the retirement decision. Possible policy alternatives are then found by a genetic algorithm developed for this purpose. Finally, the results obtained from the program are compared with previous and current reform proposals.
