Political institutions and central bank independence: A cross-country analysis

Using three quantitative measures of Central Bank independence, we apply OLS and TSLS regression methods to investigate the possible correlation between political liberty, political instability and central bank independence. For a sample of Western democracies and highly democratic developing countries we show that Cukierman's legal independence index is positively correlated with political freedom and regime political stability. It is negatively correlated with party political stability. For a sample of developing countries that excludes dictatorships we show that a special index of legal central bank autonomy is positively associated with political freedom and political stability. Finally, we observe that, for the same sample of nations, the turnover index of central bank independence is not sensitive to our political variables.
