(a). Use the DD-AA model to examine the effects of an one-time rise in the foreign price level, P* given that the future exchange rate Ee falls immediately in proportion to P*. If the economy is initially in internal and external balance, will its position be disturbed by such a rise in P*?
IS-LM-PC Analysis
