Trade Deficits and J-Curve Adjustment Paths. Assume the United States has the following import/export volumes and prices. It undertakes a major "devaluation" of the dollar, say 18% on average against all major trading partner currencies. What is the pre-devaluation and post-devaluation trade balance? What is the pre-devaluation trade balance? The revenues from exports are $ (Round to the nearest cent.) The expenditures on imports in foreign currency are fc (Round to two decimal places.) The expenditures on imports in U.S. dollars are $ (Round to the nearest cent.) Calculate the pre-devaluation trade balance below: (Round U.S. dollar values to the nearest cent and round foreign currency to two decimal places.) The new spot exchange rate after devaluation is $ /fc. (Round to four decimal places.) The new expenditures on imports in U.S. dollars are $ (Round to the nearest cent.) Calculate the post-devaluation trade balance below: (Round U.S. dollar values to the nearest cent and round foreign currency to two decimal places.)
