+ Panel A ZZ Demand, Z Y Y' Output, Y+ Panel B Net Exports Y TB OutputIn Country A, the real exchange rate (9) = 1.23, the level of Exports (X) = 45, and the level of Imports (M4) = 45. A 2% appreciation in the real exchange rate leads to a proportional increase in ll\" of 1.4% and a proportional decrease in X of 0.75%. What should be the resultant proportional change in trade balance, if the Marshall-Lemer condition has to be satised in the economy of Country A? Proportional change in trade decit = %. (Round your answer to two decimal places and include a minus sign if necessary.) Country B is in a situation of trade surplus, but the output in the economy is below the natural level of output. The graph in Panel A depicts the current output and demand equilibrium in Country B. The graph in Panel B depicts the level of trade surplus in Country B. Y is the current level of output in Country B and Y' is its natural level of output. TB is the trade balance curve for Country B
