Separation of powers with checks and balances (SP) is usually regarded as a key institution complementing elections in the control of elected officials. However, some analysts and many politicians also warn that excessive checks on the executive in the presence of polarization may lead to political inaction. We analyze the interaction between elections and SP, and study under what circumstances they complement each other. We first introduce a political agency model with ideological parties where citizens and politicians care about rents (a valence issue) and policy (a positional issue). Then, we analyze the impact of SP on the effectiveness of elections to discipline and select politicians. We demonstrate that SP unambiguously raises a majority of voters' welfare in highly polarized non-competitive political environments, because it strengthens both discipline and selection without causing political gridlock. SP also raises voters' welfare if elections are very effective at disciplining first period incumbents. Nevertheless, SP may reduce voters' welfare if most rents go undetected and reform is not a first-order issue. [ABSTRACT FROM AUTHOR]

Formal constitutional systems of separated powers often fail to sustain meaningful systems of checks and balances in presidential-style democracies. What conditions support balance in the separation of powers and what conditions provoke instability and conflict? We draw on Madisonian political theory and research addressing the separation of powers in the United States to develop a game theoretical model of inter-institutional stability and conflict within a separation of powers system. Two factors emerge as catalysts for institutional instability and conflict among the branches of government: high-stakes institutional rivalry combined with uncertainty about the public’s relative support for various branches of government. We apply the model to the experience of Honduras in 2008–2009 that resulted in the coup ousting President Zelaya which illustrates the difficulty of developing credible checks and balances.
