Question

Given the following table showing possible terms of trade for country I and country I's corresponding demand for imports of good Y at each terms of trade:                             

                     possible terms             I's quantity demanded

                      of trade                          of  imports of Y    

 

(a)                    1X:1Y or P_X/P_Y = 1                      20 units

 

(b)                   1X:2Y or P_X/P_Y = 2                      46 units

 

(c)                    1X:3Y or P_X/P_Y = 3                      69 units

 

(d)                   1X:4Y or P_X/P_Y = 4                      84 units

Calculate the supply of exports of good X by country I at each terms of trade and plot the resulting offer curve.
