Investment $-$ End of Chapter Problem

You 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. no$,$ because the minimum threshold for a stock purchase to be considered an investment is $$10,000.$ yes, because you are purchasing something that may yield more value later.

yes, bifuse there is a concensus amongst Wall St$.$ that this is considered an investment.
