This article analyzes Brazilian social security reform during the Fernando Henrique and Lula Administrations. After comparing the contexts in which the different Constitutional Amendment proposals (PECs) were submitted and the behavior by Members of Congress during the two periods, we argue that a contextual change (namely a switch in places between government and opposition) affected the distribution of preferences and resources between the players and impacted the government in the various arenas in which the game was being played, and that as a result the reformist agenda has made more progress under the current Workers' Party administration.
