The short-run aggregate supply curve (SRAS) can be written asfollows: Y = Yf b (p - pe), where Y = real GDP, Yf =full-employment real GDP, p = price level, pe = expected pricelevel, and b is a positive coefficient. The SRAS can be re-writtenas p = pe - (1/b)(Yf) (1/b)(Y). Then which of the following istrue?
A. An increase in pe will cause a rightward shift of the SRAScurve.
B. An increase in pe will cause a leftward shift of the SRAScurve.
C. An increase in Yf will cause a leftward shift of the SRAScurve.
D. Only A and C.
E. Only B and C.

| 1. | In the money market, money supply is determined by the central bank, such as the Fed in the U.S. Because of this, money supply curve is usually vertical in the short run, while the money demand curve is downward sloping. The quantity demanded of money has an inverse relationship with the interest rate, but a direct relationship with both the price level and real GDP. Therefore, when the general price level increases, what will most likely happen? | ||||||||||||||||
