| Modern environmental issues imply that decision-makers take into account opinions from experts of different spheres. Boundary organizations are institutions able to cross the gap between different areas of expertise and to act beyond the boundaries while remaining accountable to each side: by encouraging a flow of useful information, they permit an exchange to take place while maintaining the authority of each side, in order to provide a better knowledge and understanding of a situation characterized by uncertainty. Though never formally proved, this hypothesis is widely accepted based on the observation of existing boundary organizations. Through a multi-agent simulation, it is possible to assess their impact on the diffusion of opinions among experts.... |

| Two agents are engaged in a joint activity that yields a common perperiod payoff at two rounds of play. The expert announces the probability that the current state of the world is low, instead of high, at each stage. Having received the report of the expert, the decision-maker takes action at every period according to his posterior beliefs. At the end of each round of play, the true current state is verifiable. The distinctive assumption of the paper is that the decision-maker makes a subjective appraisal of the expert’s reliability: he considers the expert’s true forecasts as the outcomes of an experiment of unknown statistical bias. The paper shows that the expert will have instrumental reputational concerns, related to the future estimate of the... |

| Modern environmental issues imply that decision-makers have the capacity to take into account possibly conflicting information from distinct domains, such as science and economics. As the development of technology increases the temporal and spatial scopes of risks, decision-makers can no longer consider economic and scientific information separately but should encourage experts to work together. Boundary organizations, institutions that cross the gap between two different domains, are able to act beyond the boundaries while remaining accountable to each side (Guston, 2001). By encouraging a flow of information across the boundaries, they permit an exchange to take place, while maintaining the authority of each domain (Cash et al., 2003; Clark et al.,... |

| The paper is concerned with the interaction between two agents: an expert, announcing his probability that a particular state of the world will occur, and a non-expert decision-maker, who takes action according to his posterior beliefs. The decision-maker considers the expert an experiment of uncertain reliability and takes the received messages as the outcomes of such an experiment. The model of the expert in the decision-makers mind bears no relation with any measure of the experts actual information. The paper shows that messages will be biased, notwithstanding solidarity between the agents. However, the longer the interaction, the less severe will be the bias. |
