Utilizing a large-N data that covers about 20000 observations from about 200 countries from 1789 to 2018 from the Varieties of Democracy (V-Dem) project, and anchored on institutionalism as an overarching theory, and the nascent literature on civil-society corruption nexus, the paper looks at the predictive capacity of civil society environment, transparency of laws and predictability of enforcement, and rigorousness and impartiality of public administration in political corruption. Using a four-step hierarchical multiple regression, results show that while civil society and its structure is a significant determinant of the level of political corruption, the introduction of transparency of laws and predictability of enforcement, rigorousness, and impartiality of public administration, and civil society environment in the regression model accounted for additional variance in political corruption. Practical and theoretical implications, particularly on civil societycorruption nexus and the broader corruption-democracy linkage, are discussed.
