Central-Bank Independence, Economic Behavior, and Optimal Term Lengths
用党派性和任期长度来刻画央行独立性，分析不同政策结构对实体经济的影响，发现保守央行行长会延长最优任期并降低平均通胀，但不一定增加产出波动。
The authors parameterize central-bank independence in terms of partisanship and term length, focusing on the implications of alternative policy structures for real economic activity. While long terms of office for the central banker can reduce the role of electoral surprises, term lengths that are too long are costly if societal preferences are subject to permanent shifts. The appointment of a conservative central banker increases the optimal term length and leads to lower average inflation but need not increase the volatility of output.
