Due to structural and policy shifts, pension deficit in North Macedonia doubled over a decade and significantly outpaced the central budget deficit. The objective of the paper is to examine fiscal and development effects of few pension-reform designs. We constructed MK-PENS Dynamic Microsimulation Pension Model and simulated the effects of few reforms affecting one stakeholder and few combined reforms. Results robustly suggest that without reform and assuming only statutory pension adjustment, the deficit will remain as is. Simulated scenarios suggest that proposed pension reforms significantly reduce the pension deficit, with the most favourable results obtained within the combined scenarios of shared burden. Gradual introduction of reform's elements should come into play in case large political cost is envisaged.
