Defined contribution plan vs. defined benefits plan: reforming the legal retirement age


  • Juan Lacomba
  • Francisco Lagos


In the context of the current debate surrounding the reform of most social security systems, this paper analyzes the political economy of the legal retirement age. Using a life-cycle model, we study the effects of changing the redistributive parameters on the optimal legal retirement age in a Pay-As-You-Go social security system. Two pension plans are studied, with opposite results. In a defined contribution plan, an increase in the redistribution levels will delay the preferred legal retirement age. On the other hand, in a defined benefits plan, the same increase in the redistribution levels will lower this preferred age.
