RDP
 n.— «How about RDP? The term means, “Re-use Domestic Products,” the total sum of money spent on buying used goods. Most likely, the Japanese came up with the term, which cannot be found in dictionaries, for Japanese economists use it most.» —“Used goods signal health of economy” by Nahm Yoon-ho JoongAng (Seoul, S.
