Online interactions are frequently governed by reputation systems that allow users to evaluate each other after an interaction. Effective reputation systems can increase trust and may improve efficiency in market settings. In recent years, however, fake reviews have become increasingly...

Does social identity affect how decision makers consume and digest new information? We study this question through a theoretically informed experiment, employing a variant of the sender receiver game in which receivers can purchase reports from up to two senders. Depending on senders'...

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...

I analyse firms organisational choices when they face uncertainty about institutional conditions in foreign locations with heterogeneous final good producers and incomplete contracts. As firms learn about the conditions abroad, the increasing offshoring activity increases competition in the...

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 theoretically and empirically how monetary incentives and information about others' behavior affects dishonesty. We ran a laboratory experiment with 560 participants inspired by the "observed game" developed by Kajackaite and Gneezy (2017). We find that the extensive (the fraction of...

We conduct a laboratory experiment to explore whether loss aversion applies to social image concerns. First, subjects are ranked publicly in a social image relevant domain, an IQ test, to establish own rank as a within-subject reference point. We then induce an exogenous change in within-subject...

We investigate the presence and stability of dynamically inconsistent time preferences across contexts with and without interpersonal trade-offs. In a longitudinal experiment subjects make a series of intertemporal allocation decisions of real-effort tasks between themselves and another person....

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...
