Suppose workers and firms expect the overall price level to increase by 4%. Given this information, we would expect that: O the nominal wage will increase by exactly 4%. O the real wage will increase by 4%. O the nominal wage will increase by less than 4%. O the nominal wage will increase by more than 4%. O the real wage will decrease by 4%. Suppose there is a reduction in foreign output (Y*). This reduction in Y* will cause which of the following in the domestic country? 0 an increase in output O an increase in net exports 0 an increase in foreign consumption 0 an increase in consumption 0 a reduction in net exports Which of the following events would NOT cause a movement along aggregate supply curve in the short run? 0 an increase in the money supply O a decrease in the money supply O an increase in government spending O an increase in taxation 0 a decrease in the markup
