Outline of Final Research Achievements

This study analyzes a random search model in which agents do not know their own type. Agents with imperfect self-knowledge learn their type when they receive an offer or rejection from others. We find that an agent with imperfect self-knowledge lowers his or her reservation level if the agent receives a rejection. However, they does not raise his or her reservation level even if the agent receives an offer. As a result, a series of meetings gradually lowers his or her reservation level through the duration of the search.
In the learning process, an agent with imperfect self-knowledge frequently rejects (accepts) a person of the opposite sex whom he or she would accept (reject) when he or she knows his or her own type. This optimistic (pessimistic) behavior influences both the agent's matching behavior. Moreover, the optimism of some agents prevents the lowest-type agents from matching. However, the pessimism of some agents does not affect the matching of the lowest-type agents.
