Separation of Powers and Political Accountability
探讨政治宪法作为不完全契约如何导致权力滥用，分析选举机制不足时，行政与立法机构间的权力分立与制衡如何通过利益冲突促进相互监督，帮助选民获取信息并提升问责效果。
Political constitutions are incomplete contracts and therefore leave room for abuse of power. In democracies, elections are the primary mechanism for disciplining public officials, but they are not sufficient. Separation of powers between executive and legislative bodies also helps to prevent the abuse of power, but only with appropriate checks and balances. Checks and balances work by creating a conflict of interest between the executive and the legislature, yet requiring both bodies to agree on public policy. In this way, the two bodies discipline each other to the voters' advantage. Under appropriate checks and balances, separation of powers also helps the voters elicit information.
