We analyze differences in consumption and wealth that arise because of different degrees of rationality of households. In particular, we use a standard New Keynesian model and let a certain fraction of households be fully rational while the other fraction possesses less cognitive ability. We...

We study belief updating about relative performance in an egorelevant task. Manipulating beliefs about the ego-relevance of the task, we show that subjects update their beliefs about relative performance more optimistically as direct belief utility increases. This finding provides clean evidence...

The present paper studies the effect of monetary policy on inflation and output within a New Keynesian model with Experience-Based Learning (EBL) that renders expectations heterogeneous across age groups. Under EBL, the age-distribution directly affects the composition of aggregate expectations...

Household over-indebtedness has increased worldwide. This study investigates one possible reason for this increase: biased income expectations. Thereby, we refer to the "permanent income hypothesis", which predicts that individuals borrow more today if they expect a higher income in the future....

We analyze the impact of overconfidence on gender differences in wage expectations using elicited beliefs of German university applicants. Interestingly, female students have lower wage expectations and are less overconfident than their male counterparts. Oaxaca-Blinder decompositions show that...

Standard program evaluations implicitly assume that individuals are perfectly informed about the considered policy change and the related institutional rules. This seems not very plausible in many contexts, as diverse examples show. However, evidence on how incomplete information affects the...

We explore the consequences of losing confidence in the price-stability objective of central banks by quantifying the inflation and deflationary biases in inflation expectations. In a model with an occasionally binding zero-lower-bound constraint, we show that an inflation bias as well as a...

Exploiting the natural experiment of the German reunification, we examine how consumers adapt to a new environment in their macroeconomic forecasting. We document that East Germans expect higher inflation and make larger forecast errors than West Germans even decades after reunification....

I show how irrational ideas and rumors can drive asset prices - not because anyone believes them, but because they are commonly known without being common knowledge. The phenomenon is driven by short-term market participants who are well-informed about the information that others have, and who...

Many papers have reported behavioral biases in belief formation that come on top of standard game-theoretic reasoning. We show that the processes involved depend on the way participants reason about their beliefs. When they think about what everybody else or another "unspeci fied" individual is...
