Abstract Game-theoretic models of political decision-making regard policy outcomes as
a combined result of actor preferences and institutions. This paper explores the effects of
adding relative issue salience to the analysis. I focus on non-cooperative models of
complete and perfect information that are based on the concept of structure-induced
equilibrium (Shepsle in Am J Polit Sci 23(1):27-59, 1979). Assuming a progressive
agenda-setter and two conservative voters, I show how a change of the relative issue
salience for players in a game results in a different equilibrium outcome in a political
decision-making body.

1. Introduction
For an organisation in order to change its policies, game theoretic models assume that actor
preferences and institutional arrangements such as the price mechanisms or a certain voting
rules are of central importance (Kreps, 1990: 3-6). Institutions are assumed to 'channel'
preferences by specifying the strategies which actors in a decision situation have at their
disposal. Whenever an individual is confronted with having to decide on two issues that are
part of the same decision situation, there might be a difference in how important each of
the issues are for the actor. This paper analyzes how the relative importance of one issue
