About thesis 'Communication and Learning in Decision'

Making a decision is not an easy task. For this reason, before purchasing a new house, voting for a political party, or undergoing a complex medical operation we often seek additional information about the options available to us. Yet, before relying on such information we should consider two important questions. First, is the source of information trustworthy? Second, do we understand the received information correctly?

This thesis touches on both these questions. The first part of the thesis constructs theoretical models to explore the first question. It focuses on environments in which an advice given to a decision maker is influenced by the advisor's wish to be known as a 'good advisor'. It is shown how policy choices and organizational structure are determined in such environments. The second part of the thesis addresses the second question. Employing a laboratory experiment, it explores how changes in the cost of given information can affect the manner in which it is used by decision makers.
