For the same given as in Problem 1, derive the supply curve of exports of the tradeable commodity for above-equilibrium prices.
Problem 1
From the negatively sloped demand curve and the positively sloped supply curve of a nation’s tradeable commodity (i.e., a commodity that is produced at home but is also imported or exported), derive the nation’s demand curve of imports of the tradeable commodity for below-equilibrium prices.
