In Brief

Presidentialism has separation of power, but varies when it comes to separation of purpose (see below for definitions). Having both separation of power and separation of purpose introduces the potential for deadlock, instability, and balkanization; there are many veto players, so any compromises reached in this case must be based on broad consensus, making the status quo very difficult to change. However, if there is extreme unity of purpose in presidentialism, then it can be highly decisive (perhaps dangerously so) as the branches of government (divided in power but united in purpose) enact radical changes to policy.

Hypothesis: few presidential regimes are located at either of these two extremes, yet the occurrence of the two extremes "has fueled a substantial literature claiming that presidentialism is dysfunctional or even 'perilous'." Most presidential regimes are between these extremes, thus tame.

See Cox and McCubbins (2001, from the same volume), "The Institutional Determinants of Economic Policy Outcomes." It is the chapter immediately preceding this one, and it defines "separation of power" and "separation of purpose" in a more general sense before this chapter applies the same distinction to analyze presidential policy more closely.

Definitions

  • Separation of power: executive and legislative branches have independent authority due to separate origin (elections) and survival (no confidence necessary).
  • Separation of purpose: divided government--either divided by parties, or because presidents and legislators represent different constituencies (national vs district, thus national vs local concerns). Electoral laws largely determine this.
