Where did Hyper-Presidentialism Go? The Origin of Bills and Laws Passed in Chile, 1990–2022

Abstract

While the success of the president's legislative agenda is measured by examining the rate of passage of presidential bills (the batting average), the dominance of the president over the legislative process can be better understood by considering the share of presidential bills among bills introduced and laws enacted. Studies on the success of the president's agenda outnumber those on the dominance of the president, but the latter more directly address the debate on the proactive legislative powers of the executive. Reviewing the 13,358 bills introduced and the 2603 laws enacted in the eight legislative terms in Chile between 1990 and 2022, we associate the constitutional changes in 2005 and the electoral reform of 2015 with a decline in the legislative dominance of the president. There was a progressive decline in presidential dominance in legislative inputs and outputs long before the 2019 social upheaval weakened the Piñera government.
