Even we feel the rating of government bonds by rating agency is not clear. It sounds like based on rumor or feeling of the people. However the rating is almost controlling the economy of the countries. That should be more clearly valuated based on data. Someone could feel that Italy is not fare to investigate or accuse rating agency. I feel really fare and most of countries should accuse, even Japan. We feel Japan economy is really bad, though the rating can be too high or too low.
