The Decline of Non-Military Montepíos in Early Mexico: A Historical, Actuarial, and Financial Approach

Summary/Abstract: This article examines the historical and actuarial causes behind the decline of non-military Montepíos - public pension-paying institutions for civil servants in New Spain (early Mexico) - following the conclusion of the wars of independence in 1821. By combining historical, institutional and actuarial perspectives, it argues that their collapse resulted less from the fiscal and political turmoil of early independent Mexico than from their structural design flaws. These Montepíos operated as pay-as-you-go (PAYG), defined-benefits systems lacking mechanisms to balance contributions and payouts, leading to chronic underfunding. Through archival evidence and demographic data, this paper reveals a mismatch between short contribution periods and long deaccumulation periods, driven partly by gender and marriage patterns that extended the duration of survivor pensions. This study contributes to the understanding of how early welfare institutions in Spanish America anticipated the challenges of modern pension systems, demonstrating that institutional fragility often arises from the interaction between actuarial design and socio-demographic dynamics.
