Soft Law on Regulation

There are many, many different soft laws or unwritten rules everywhere even if there would be in a barbarian village. 

This book was written as a result of  the "21st Century COE Projects" selected by the Japan government.

I'm interested in the chapter of "the soft laws between the governments and the markets". The social scientist researched the actual garantees of the ungarantee national and local government bonds. The other social scientist will publish the book "Soft Law on Trading in the Markets" soon. I'm looking forwad to it.
