Answer to Question 1

The J-curve illustrates graphically the dynamic adjustment of NX to a depreciation when the Marshall-Lerner condition does not hold initially but does hold eventually. If ML does not hold initially, a depreciation will cause NX to fall. Over time, the quantities of exports and imports will adjust causing NX to rise and eventually increase above its initial level. Tracing out the path of NX in this case resembles a J. Hence, the J-curve.
