Defined as a credible threat that strengthens the bargaining position of the executive, presidential vetoes, widely understudied, carry a stigma of confrontation between state powers. But under some institutional setups, partial vetoes can be an additional step in the executive–legislative bargaining process. After a discussion of whether partial vetoes are a proactive legislative tool or a bargaining tool to induce executive–legislative cooperation, we test four hypotheses using the 2,346 bills introduced in Chile between 1990 and 2018 that reached a vetoable stage. We identified 97 partial vetoes (4.2 percent) and one total veto. Presidents are more likely to veto bills with more complex legislative processes and when they have stronger support in at least one chamber, but more popular presidents do not veto more bills. As most presidential vetoes in Chile are partial, they are an additional executive–legislative bargaining step in the lawmaking process rather than evidence of hyperpresidentialism.

The issuance of parliamentary questions (PQ) in presidential democracies reflects an effort to connect with the electoral constituency to advance the legislator's career. We postulate six hypotheses on the association between party affiliation, career advancement and district-level incentives and the issuance of PQs in Chile's presidential multiparty democracy. We test them using a novel dataset containing 68,424 inquiries (oficios legislativos) issued by Chamber of Deputies legislators in three legislative terms (2006–2018). Though district-level variables play a role in the issuance of PQs, incentives of political ambition do not. As opposition coalition legislators make more use of PQs than ruling coalition legislators, there is preliminary evidence to associate PQs with a possible oversight role.

Conflicts resulting from the dual legitimacy problem of presidential systems (where the president and the legislature are elected by different majorities) sometimes result in legislative gridlock – a point made by those who criticize the alleged perils of presidentialism. The socialist government of Salvador Allende (1970–73), that ended with the breakdown of democracy, is often used as a poster child for legislative gridlock. With information on the 23,798 bills and 12,809 laws enacted in Chile between 1932 and 1973, we compare the passage of legislation in eight presidential terms and demonstrate that not to be the case. Legislative output showed an upward trend after the 1943 constitutional reform but was on a downward trend since the mid-1960s, before the 1970 constitutional reform restricted the scope of bills that legislators could introduce. Under Allende, while 1653 bills were introduced (438 of which were presidential bills), 642 laws were passed (38.8% and 68.2%, respectively) – compared to 53.8% and 39.9% for all presidents in the period, respectively. The evidence does not justify the claim that there was legislative gridlock under Allende. Instead, variations in legislative output across presidential terms in Chile can be explained by changes in the rules of the legislative process.

Do institutions constrain presidential power in Africa? Conventional wisdom holds that personalist rule grants African presidents unchecked powers. Consequently, there is very little research on African institutions such as legislatures and their impact on executive authority. In this article, the author uses original data on the exercise of presidential authority (issuance of subsidiary legislation) to examine how legislative independence conditions presidential rule making in Kenya. The study exploits quasi-exogenous changes in legislative independence, and finds that Kenyan presidents issue relatively more Legal Notices under periods of legislative weakness, but are constrained from doing so under periods of legislative independence. These findings shed new light on institutional politics in Kenya, and illustrate how executive–legislative relations in the country conform to standard predictions in the literature on unilateral executive action.
