@ahorn What do you consider to be the key difference(s) in definition between "saving" and "investing"?
@MHall If it specifically requires economics knowledge to answer, and meets the site guidelines, then post on economics.se. If it only requires maths knowledge to answer, and meets that site's guidelines, post it on math.se
@EnergyNumbers I think investing happens when one directly gets the benefits of a firm's investment. A few days ago I came up with a rule of thumb that savings are based on the repurchase rate and investments aren't.
