Prime ministerial autonomy and intra-executive conflict under semi-presidentialism

Abstract

This article answers why intra-executive conflict varies across semi-presidential democracies. The literature verifies that intra-executive competition tends to be higher when the president holds less power to dismiss the cabinet, coexists with a minority government, or the president's party is not represented in the cabinet. This paper, therefore, integrates these factors to construct an index of prime ministerial autonomy, proposing that its relationship with the probability of intra-executive conflict is represented by an inverted U-shaped curve. That is, when the prime minister is subordinated to an elected president, or conversely, enjoys greater room to manoeuvre in the executive affairs of the government, the likelihood of conflict is low. In contrast, significant confrontation emerges when the president claims constitutional legitimacy to rein in the cabinet, and controls the executive to a certain degree. This study verifies hypotheses using data on seventeen semi-presidential democracies in Europe between 1990 and 2015.
