“…The paper relates to the empirical literature using cross-and within-country variation in observational data to investigate the relationship between reliance on tax or windfall revenue and governance indicators such as democratization, provision of public goods, and corruption. This literature largely shows that good governance is positively associated with reliance on tax revenues and negatively associated with reliance on windfall revenues (Ahmadov, 2014;Besley and Persson, 2014;Ross, 2015;Gadenne, 2017;Martínez, 2016;Prichard et al, 2018), with some notable exceptions (Haber and Menaldo, 2011;Herb, 2005). 2 However, with the exception of Martínez (2016) and Gadenne (2017), most of these studies do not identify a causal relationship between tax or windfall revenue and accountability, and do not provide evidence for the underlying mechanisms explaining it.…”
