The Anglo-American double-member districts employing plurality-at-large are frequently criticized for giving a large majority premium to a winning party, since the large premium may decrease proportionality of the elected assembly relative to single-member districts. We demonstrate that the...

The Anglo-American double-member districts employing plurality-at-large are frequently criticized for giving a large majority premium to a winning party. In this paper, we demonstrate that the premium stems from a limited degree of voters' discrimination associated with only two positive votes...

Using a unique set of electoral rules present in the Austrian state of Vorarlberg, we explore the question whether local electoral rules affect the size of local governments. We find evidence that party--list system is associated with higher levels of expenditure and that direct elections of the...

Social scientists have long speculated about individuals' tendencies to misrepresent their preferences in order to affect the outcome of social choice mechanisms. The fact that preference orderings are generally unobserved, however, has made it very difficult to document strategic behavior...

Whether individuals vote strategically is one of the most important questions at the intersection of economics and political science. Exploiting a flaw in the German electoral system by which a party may gain seats by receiving fewer votes, this paper documents patterns of strategic voting in a...

A group of rational individuals with common interest need to select one of two outcomes. The optimal decision depends on whether certain premises or pieces of evidence are established as being true, and each member receives a noisy signal of the truth value of the relevant premises. Should the...

This paper analyzes a sequential voting mechanism that eliminates at each round one candidate, until only one of them is left (the winner). The candidates are the voters and they only differ across their skill level. The payoff allocated to the winner depends on the sequence of elimination of...

Prior research on “strategic voting” has reached the conclusion that unanimity rule is uniquely bad: it results in destruction of information, and hence makes voters worse off. We show that this conclusion depends critically on the assumption that the issue being voted on is exogenous, i.e.,...

Using computer simulations based on three separate data generating processes, I estimate the fraction of elections in which sincere voting will be a core equilibrium given each of eight single-winner voting rules. Additionally, I determine how often each voting rule is vulnerable to simple...

Interest in prediction markets has increased in the last decade, driven in part by the hope that these markets will prove to be valuable tools in forecasting, decision-making and risk management - in both the public and private sectors. This paper outlines five open questions in the literature,...
