Contributions to social security in Argentina, Chile and Uruguay: Densities, transitions and duration

Pension programs in Latin America have low coverage. We use large panel databases coming from administrative records of Argentina, Chile and Uruguay to characterize the histories of contribution of the population. We compute three indicators: density of contribution, transition rates and duration of the spells of contribution and no contribution. The picture that emerges is worrisome. The density of contributions is low on average and pretty heterogeneous across the population. The spells of contribution are short and interruptions are frequent. Transition rates are higher at early ages and tend to decline later in life, indicating high turnover among young individuals.
