Partial Presidential Vetoes and Executive–Legislative Bargaining: Chile, 1990–2018

Abstract

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.
