When do different systems of government lead to similar power-sharing? The case of government formation

Abstract

AbstractRecent studies provide evidence that the absence of a no-confidence procedure in presidential systems is crucial for understanding why the allocation of portfolios does not follow the same pattern in both parliamentary and presidential democracies. In this study, I argue that distinctions within presidential systems must be used to explain the substantial variation in the allocation of portfolios to presidential parties. I theorize that when the president is more dependent upon the legislature to make and enact policies, the balance of power in presidential cabinets is more likely to reflect the balance of power in the legislature. In this case, the presidential cabinet can resemble the proportional cabinets usually formed in parliamentary systems. With new data from 20 presidential democracies worldwide spanning more than 70 years, the results support the expectation of a greater formateur's advantage when presidents have greater institutionally-granted powers to influence the policy agenda in the legislature.
