Are You Being Served? Political Accountability and Quality of Government
研究了公民如何通过选举和信息约束来问责政治家，发现信息充分的选民能解释政府绩效和腐败水平一半到三分之二的差异。
How well any government functions hinges on how good citizens are at making their politicians accountable for their actions. Political control of public officials depends on two factors. First, free and regular elections allow citizens to discipline politicians—the credible threat of losing office in the next period compels policy makers to respond to the voters' interests. Second, and equally important, the degree of citizen information curbs the opportunities politicians may have to engage in political corruption and management. The presence of a well-informed electorate in a democratic setting explains between one-half and two-thirds of the variance in the levels of governmental performance and corruption.
