Question

Voluntary exchanges happen when both parties expect to _____.
gain
lose
barter

Answer 1

I would say 'barter'. Barter means exchange. 'Gain' would not work because although you are receiving something, you are losing something at the same time. Similar with 'loss'.

Answer 2

I think the correct answer from the choices listed above is the third option. Voluntary exchanges happen when both parties expect to barter. It would be that both gain something from it so an exchange happens. Hope this answers the question.
