For simplicity sake: Please can you explain to me what does this mean...."trade increases globally by 10%"?
assuming Country A = 100 assuming Country B = 100
does it mean....
1) 10% for each country so new trade means
Country A = 110 Country B = 110
or does it mean...
2) 5% for country A and 5% for country B, so new trade is
Country A = 105 Country B = 105
Thank you for your time and effort in helping me with this question
