Abstract: In this paper we take a close look at some of the particular pathways by which majoritarian and consensual institutions affect governability. We dem-onstrate that the mix of majoritarian and consensual institutions found within a country can influence these pathways quite dramatically, such that they produce rather different consequences for governability, even when these pathways are relatively similar in nature. Particularly, we focus on the rules governing the relationship between the President and the Legislature, especially the appropria-tion of amendments proposed by legislators. In some presidential countries, the President possesses a partial veto (or a line-item veto), which allows him/her to approve or strike appropriations, which legislators introduce in amendments.

One kind, individual amendment, is linked to the majori-tarian institution of a powerful presidency and therefore helps to increase gov
