Eine neue Studie des ifo Instituts zeigt, dass Bundestagsabgeordnete von CDU/CSU, die in sicheren Wahlkreisen gewählt wurden, mit einer deutlich höheren Wahrscheinlichkeit gegen die Ehe für alle gestimmt haben als Abgeordnete aus umkämpften Wahlkreisen. Eine Erhöhung des Stimmenvorsprungs...

In his seminal Social Choice and Individual Values, Kenneth Arrow stated that his theory applies to voting. Many voting theorists have been convinced that, on account of Arrow’s theorem, all voting methods must be seriously flawed. Arrow’s theory is strictly ordinal, the cardinal aggregation...

The paper elaborates the idea that voting is an instance of the aggregation of judgments, this being a more general concept than the aggregation of preferences. To aggregate judgments one must first measure them. I show that such aggregation has been unproblematic whenever it has been based on...

The paper challenges the 'orthodox doctrine' of collective choice theory according to which Arrow’s 'general possibility theorem' precludes rational decision procedures generally and implies that in particular all voting procedures must be flawed. I point out that all voting procedures are...

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...

This paper analyzes voting on a linear income tax which is redistributed lump sum to the taxpayers. Individuals can evade taxes, which leads to penalties if evasion is detected. Since preferences satisfy neither single peakedness nor single crossing, an equilibrium may not exist. When it does...

The paper argues that the weakest link principle, which has been widely used as a measure of ultimate owners? control rights, has a number of serious problems. A theoretically more satisfactory method of measuring control rights, based on voting power indices, is proposed, and the different...

This paper analyzes a recent ballot in which two virtually identical popular initiatives, both demanding a decrease in the legal age of retirement in Switzerland, led to differences in approval rates of nearly seven percentage points. Based on this unique natural experiment, the existence of...

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...

Ten Central European countries became members of the European Union in the years 2004 - 2007. They constitute 20% of the EU's total population; and even though their economic output is much lower, it rises dynamically. New members' impact on the EU policies has nevertheless been limited. This is...
