We analyze the costs and benefits of using social image to foster virtuous behavior. A Principal seeks to motivate reputation-conscious agents to supply a public good. Each agent chooses how much to contribute based on his own mix of public-spiritedness, private signal about the value of the...

Do people only reject interference and keep control in order to affect the outcome? We find that 20% of subjects reject unrequired help and insist on their solution to a problem – although doing so is costly and does not change the result. We tease out the motives by varying the information...

Why do farm households inefficiently allocate resources across the plots they cultivate? We explore how these production inefficiencies relate to consumption decisions and information sharing within the household. In a lab-in-the-field experiment, male producers allocate too few inputs to their...

This paper reviews experimental studies that investigate the effects of communication on behavior in organizational settings. Two main classes of studies are identified: (a) studies on coordination and competition, which include experimental research that tests whether communication can help to...

Credence goods markets with their asymmetric information between buyers and sellers are prone to large inefficiencies. In theory, poorly informed consumers can protect themselves from maltreatment through sellers by asking for second opinions from other sellers. Yet, empirical evidence whether...

I evaluate the accuracy of people's subjective probability expectations for using various health services. Subjective expectations closely reflect patterns of observed utilization, are predicted by the same covariates as observed utilization, and correlate with objective measures of risk. At the...

When groups face difficult problems, the voice of experts may be lost in the noise of others' contributions. We present results from a 'naturally noisy' setting, a large first-year undergraduate class, in which the 'expert's voice is lost' to such a degree that it is in fact optimal for all...

This paper investigates experimentally how the inclination to cheat changes when agents report the result of multiple realizations of a (private information) stochastic event rather than a single outcome. Extreme outcomes clearly signal opportunistic behavior with multiple realizations. The...

Leaks are pervasive in politics. Hence, many committees that nominally operate under secrecy de facto operate under the threat that information might be passed on to outsiders. We study theoretically and experimentally how this possibility affects the behavior of committee members and the...

This paper examines the unintended strategic effects of non-linear incentives in public policies. A system of health care subsidies structured in discrete intervals may lead to strategic behaviour. We provide new evidence on this issue, focusing on a case where the strategic actions are taken by...
