An increase in money wages would be inflationary if______.
A.wages increase at a higher rate than real output
B.productivity gains exceed the wage increase
C.the money supply remains constant as the wage rate increases
D.an expansion of the money supply accompanies the increase in the wage rate
Our model takes the price level P as given in the short run,but in reality the currency appreciation caused by a permanent fiscal expansion might cause P to fall a bit by lowering some import prices.If P can fall slightly as a result of a permanent fiscal expansion,is it still true that there are no output effects? (As above,assume an initial long-run equilibrium.)
