Abstract
The asymmetry of information and various principal-agent relations can be found in the tourism industry. They might cause a problem of what we call moral hazard. This study attempts to find out the best way to bring out the highest level of efforts from an agent. It is necessary to monitor the signals given by an agent, and by monitoring as many signals as possible it is possible to have a small margin of error. Most travel agencies depend on only a few signals to judge the hospitality skills of a tour conductor. In order to reduce the number of errors in monitoring, they should increase the number of signals evaluated.
