THE ROBUSTNESS OF THE STRUCTURE-INDUCED EQUILIBRIUM

This paper analyzes the question of the existence of a structure-induced equilibrium (SIE) under assumptions weaker than those considered by Kenneth Shepsle (1979). It tums out that the existence result is extremely fragile: counterexamples show that weakening almost any of the assumptions of the original theorem can result in the nonexistence of an SIE. I then utilize the insights of these counterexamples to construct new models in which SIE will exist and derive implications from these models for questions of legislative politics.
