Social Security Reform: Transition from Pay-As-You-Go to Fully Funded System
Fully Funded System. Pay-as-you-go System. Private Pension. Public Pension. Social Security Contributions. Social Security Reform.
Due to the deficit in social security system in many economies, structural reforms in the current pay-as-you-go system are commonly discussed and the establishment of a fully funded system is a central topic. In this case, it is necessary to analyse if both systems are seen as substitutes ou complements for each other. In the case the systems are seem as substitutes, then there is an oppotunity for future pension reforms to implement a systems’ transition. Even more, in the case a fully funded system is stablished, a return rate needs to be set to capitalize the contributions, and the eventual surplus of the capitalized social security needs to be directed. Therefore, assuming that the national government is the only one who can set the return rate of the fully funded system, that the eventual surplus generated in this system should be distributed to the pay-as-you-go system, that the government’s goal is to maximize the social welfare and the newly workers will be able to choose to which system to contribute, we propose a model to calculate the optimal return rate that need to be settled by government and we estimated the proportion of the population that will choose to contribute to each social security system.
