"Principles of Economics, Volume 1" Hideyuki Adachi / Shota Ishikawa / N. Gregory Mankiw Price: ¥4000 This was a textbook for a private university economics department. I purchased it a year and a half ago. It's generally clean, but there's noticeable creasing on the last few pages. There's also a small tear at the bottom of a few pages in the middle. Please consider purchasing if you are okay with this. #HideyukiAdachi #Hideyuki_Adachi #ShotaIshikawa #Shota_Ishikawa #N.GregoryMankiw #book #society/economics_finance
