This article presents the CEDE Pension Model, a microsimulation tool designed to project key variables of Colombia’s pension system. The model integrates administrative data, household surveys, and institutional parameters to simulate labor histories using Markov chains and to project the number of older adults who will receive pension benefits through 2100. Its design enables the evaluation of policy options for old-age economic protection, highlighting trade-offs across coverage, equity and progressivity, adequacy, and fiscal sustainability.
