Interactions between players with private information and opposed interests are often prone to bad advice and inefficient outcomes, e.g. markets for financial or health care services. In a deception game we investigate experimentally which factors could improve advice quality. Besides advisor...

In many economic contexts, an elusive variable of interest is the agent's belief about relevant events, e.g. about other agents' behavior. A growing number of surveys and experiments ask participants to state beliefs explicitly but little is known about the causal relation between beliefs and...

We investigate experimentally whether individuals or groups are more lied to, and how lying depends on the group size and the monetary loss inflicted by the lie. We employ an observed cheating game, where an individual's misreport of a privately observed number can monetarily benefit her while...

In cases of conflict of interest, people can lie directly or evade the truth. We analyse this situation theoretically and test the key behavioural predictions in a novel sender-receiver game. We find senders prefer to deceive through evasion rather than direct lying, more so when evasion is a...

We experimentally analyze leading by example in a public goods game with two permanent and two temporary group members. Our results show that leadership when permanent and temporary members interact leads to lower contributions than interaction without leadership.

We study theoretically and experimentally the role of fatigue and recovery within a competitive work environment. At work, agents usually make their effort choice in response to competition and monetary incentives. At the same time, they have to take into account fatigue, which accumulates over...
