The year 2012 was the 30th anniversary of William H. Riker’s modern classic Liberalism against populism (<CitationRef CitationID="CR56">1982</CitationRef>) and is marked by the present special issue. In this introduction, we seek to identify some core elements and evaluate the current status of the Rikerian research program and its...</citationref>

All democratic systems are theoretically open to so-called election inversions, i.e., instances wherein a majority of the decision makers prefer one alternative but where the actual outcome is another. The paper examines the complex 1975 Danish government formation process, which involved five...

From a formal point of view, a composite indicator is an aggregate of all dimensions, objectives, individual indicators and variables used for its construction. This implies that what defines a composite indicator is the set of properties underlying its mathematical aggregation convention. In...

Voting procedures are known to be plagued with a variety of difficulties such as strategic voting, or where a voter is rewarded with a better election outcome by not voting, or where a winning candidate can lose by receiving more support. Once we know that these problems can occur, the next...

It is well known that proposers have an advantage in the canonical model of bargaining in legislatures: proposers are sure of being part of the coalition that forms, and, conditional on being in a coalition, a player receives more as a proposer than as a coalition partner. In this paper I show...

When collective choices are made in more than one round and with dif¬ferent groups of decision-makers, so-called election inversions may take place, where each group have different majority outcomes. We identify two ver¬sions of such compound majority paradoxes specifically, but not...

In voting theory, monotonicity is the axiom that an improvement in the ranking of a candidate by voters cannot cause a candidate who would otherwise win to lose. The participation axiom states that the sincere report of a voter’s preferences cannot cause an outcome that the voter regards as...

A theory is developed to explain all positional voting outcomes that can result from a single but arbitrarily chosen profile. This includes all outcomes, paradoxes, and disagreements among positional procedure outcomes as well as all discrepancies in rankings as candidates are dropped or added....
