摘要:The Participatory Budget has been described in literature as a democratic innovation bearer of virtues, whether in the capacity for rationalization of state action, is the potential to alter historical patterns of relationship State x Society in Brazil, such as clientelism. Recent studies also point to possible impacts of experience in attitudinal and behavioral patterns of participants, so the OP would produce some kind of political learning. Looking empirically explore these potential positive effects of this study is to examine to what extent the participatory involvement in this institution can be understood as conditioning or determining a set of indicators collected by the conventional literature on the label of political culture. Therefore, we intend to question whether it is possible, from participatory institutional innovations, produce changes in the pattern of subjective orientations and attitudes of citizens. To achieve these goals we take as a set of empirical data on the experience of participatory budgeting in Porto Alegre developed. Such information comes from one survey conducted by the Center for Research on Latin America (NUPESAL) for the year 2000. The paper is organized into three parts: First, we discuss the theoretical issues involved in this debate. On Monday, we present the empirical data. In the end, we set out some conclusions and perspectives for further work.
