ou invest $1,000 in stocks. Would a macroeconomist call this an investment? Why or why not? An economist would say no, because you are just buying an existing asset without creating any new productive capacity in the economy. yes, because you are purchasing something that may yield more value later. yes, because there is a concensus amongst Wall St. that this is considered an investment. no, because the minimum threshold for a stock purchase to be considered an investment is $10,000.
