“…A key insight of collective action theory is that the nature and sources of a state's revenue have a profound impact on a state's political policies, especially in relation to the nature of public goods, bureaucratization, and the nature of the governing elite's power (Blanton and Fargher, 2008: pp. 250-252, Table 10-3;Fargher and Blanton, 2007;Levi, 1988). For example, in our comparative study of 30 pre-modern states, we found that a measure of the degree to which the main revenue sources are produced by commoners (e.g., what we call ''internal revenues'' such as agrarian surpluses from a free peasantry) is highly correlated with the quantity of public goods provided by the state (r = .79, p < .01, N = 30), with degree of bureaucratization (r = .61, p < .01, N = 30), and slightly less so, but still significantly with degree of control that can be exercised over the agency of governing principals (r = .44, p < .05, N = 30) (Blanton and Fargher, 2008: Table 10-3).…”
