Abstract
] Despite the political odds against such outcomes, in the 1990s, a significant number of countries in Latin America introduced major changes in the way health and education systems operated and set in motion fundamental changes in the structure of pension systems. This paper explores why reforms are adopted more frequently than political economy models predict. Analysis of the process of reform must be incorporated into political analysis if concepts and models are to become more helpful in understanding when and why change occurs. In this process, reformers and their strategic decisions, as well as the organizational characteristics of winners and losers and the constraints introduced by political institutions, become key factors in determining reform destinies.
