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...

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...

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...

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...

We study the role of experience in the formation of asset price bubbles. Therefore, we conduct two related experiments. One is a call market experiment in which participants trade assets with each other. The other is a learning-to-forecast experiment in which participants only forecast future...
