makes sense. i said they trade on the basis of comparative advantage to export G/S they have CA in and import G/S other countries have CA in. i also mentioned about opportunity cost. you reckon that's enough for 3 marks?i grad two years ago but reasons you could say are:
- comparative advantage of production
- increase standard of living and employment oppourtunities of a nation
- gain access to goods that are not available domestically, improve material wellbeing
