Determining long$-$term exchange rates

Consider two countries, the United States and Japan, that trade with each other. Suppose that the productivity growth in the United States accelerates, but it remains the same in Japan. The following graph shows the supply and demand for the Japanese yen in the United States before the change in productivity. The vertical axis is the exchange rate of the yen in terms of the dollar, and the horizontal axis is the quantity of yen.

Show how the change in productivity affects the equilibrium exchange rate by shifting one or both of the curves on the graph.

Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther.

As a result of the change in productivity, the U$.$S$.$ dollar $q,$
