There are many situations in which different groups make collective decisions by committee voting, with each group represented by a single person. A natural question is what voting system such a committee should use. Concepts based on voting power provide guidelines for this choice. The two most...

Theorien der Behavioral Labor Economics weichen vom Standardmodell der Ökonomie ab und stellen insbesondere die diesem Standardmodell zugrunde liegende Annahme von rationalen und egoistischen Entscheidern – der Annahme des Homo oeconomicus – infrage. Sie unterstellen Handlungsweisen, die...

Expectations play a crucial role in modern macroeconomic models. We replace the common assumption of rational expectations in a New Keynesian framework by the assumption that expectations are formed according to a heuristics switching model that has performed well in earlier work. We show how...

Expectations play a crucial role in modern macroeconomic models. We consider a New Keynesian framework under a behavioral model of expectation formation and under rational expectations. Contrary to the rational model, the behavioral model predicts that inflation volatility can be lowered if the...

Among the wide variety of voting power indices, the public good index (PGI) is one of the less well-known ones. Holler (forthcoming) posits hypotheses about why this is the case. In response to these hypotheses, I share a few thoughts about voting power in general and about the popularity of the PGI

Credit default swaps (CDS) played an important role in the financial crisis of 2008. While CDS can be used to hedge risks, they can also be used for speculative purposes (as occurred during the financial crisis) and regulations have been proposed to limit such speculative use. Here, we provide...

Under full rationality a labor income tax and a corresponding employer's contribution are equivalent. Without full rationality this equivalence is no longer obvious. If people react differently to these duties this has direct impact on policy making and also has consequences for optimal taxation...
