ABSTRACT
Reform towards greater central bank independence is generally seen as intertwined with institutional development more broadly. However, the largest empirical study to date on the determinants of central bank independence found a negative relationship to institutional quality variables. This paper argues that this is related to sample length: using a different dataset for central bank independence with a considerably longer sample, institutional variables are found to be positive and highly significant determinants of central bank independence.

Notes
1 Definitions of these institutional variables can be found at http://info.worldbank.org/governance/wgi/#doc.
2 Other studies tend to focus on specific political factors, rather than institutional determinants in general. For instance, Crowe and Meade (Citation2008) and Bodea and Hicks (Citation2015) examine CBI in relation to democracy versus dictatorship. Using the dataset of Garriga (Citation2016), Agur (Citation2018) analyzes the impact of political nationalism on CBI. See de Haan and Eijffinger (Citation2019) for a survey of the literature on the politics of CBI.
3 The index of Cukierman, Webb, and Neyapti (Citation1992) measures de jure independence, and an increase in de jure independence does not always translate into de facto independence (Cukierman Citation2008). However, de jure independence of a central bank is often a prerequisite for de facto independence and successful monetary reform more broadly (Freedman and Ötker-Robe Citation2010).
4 The World Bank’s Database of Political Institutions goes back to 1975 for many countries, but only covers political data, which would not provide close coverage for the types of institutional variables used in Dincer and Eichengreen (Citation2014).
5 More direct measures of trust, from the World Values Survey, are only available for a small subset of countries during our sample period.
