Afinal, Quais Instituições Importam? Equilíbrios Políticos, Concentração e Dispersão de Poder e Decisões

Government divided into veto points that neutralize each other? This article revisits the literature that examines the effects produced by different institutional designs on stability and polyarchic performance, showing that there is no univocal and consensual connection between institutional configuration and generated results.
