The modern Condorcet jury theorem states that under weak conditions, when voters have common interests, then elections will aggregate information when the population is large, in any responsive and symmetric equilibrium. Here, we study the performance of large elections with population...

We analyze the ECB Governing Council's voting procedures. The literature has by now discussed numerous aspects of the rotation model but does not account for many institutional aspects of the voting procedure of the GC. Using the randomization scheme based on the multilinear extension (MLE) of...

The modern Condorcet jury theorem states that under weak conditions, when voters have common interests, elections will aggregate information when the population is large, in any equilibrium. Here, we study the performance of large elections with population uncertainty. We find that the modern...

In this article, we empirically study the survival of the ruling party in parliamentary democracies using a hazard rate model. We define survival of a crisis as being successful in a critical vote in the parliament. We develop a general probabilistic model of political crises and test it...

Several power indices have been introduced in the literature in order to measure the influence of individual committee members on the aggregated decision. Here we ask the inverse question and aim to design voting rules for a committee such that a given desired power distribution is met as...

This paper deals with the problem of calculating the Shapley-Shubik power index in weighted majority games. We propose an efficient Monte Carlo algorithm based on an implicit hierarchical structure of permutations of players. Our algorithm outputs a vector of power indices preserving the...
