This is a set of "Introduction to the World Economy in One Book" and "New Common Sense of the World Economy 2017," supervised by Mr. Ryomaru Kumagai and edited by Daiwa Institute of Research. "Introduction to the World Economy in One Book" has some minor wrinkles and damage on the obi (belly band) and cover (please refer to the photos), but there are no writings and no noticeable scratches or dirt. "New Common Sense of the World Economy 2017" also has some minor wrinkles and damage on the obi and cover. Additionally, there are a few writings and lines drawn inside, and one folded corner (please refer to the photos). However, the writings and lines are only in about 5 places and are not considered significant. #World #Economy #Introduction #CommonSense
