| 11. | Suppose the wage rates of workers are based on the expected price level. If there is an unexpected increase in AD, it will cause the actual price level to increase. Then workers should raise their expected price level and negotiate a higher wage rate. Then which of the following is most likely to be true when the expected price increases? | ||||||||||||||||

| 12. | Suppose the economy is in the long-run equilibrium, i.e., Y = Yf, and there is an unexpected decrease in AD. Assume that Yf is fixed, then which of the following is most likely to be true? | ||||||||||||||||

| 13. | The short-run (SR) equilibrium is the intersection between AD and SRAS, and long-run (LR) equilibrium is the intersection between AD and LRAS. Every LR equilibrium is a SR equilibrium, but a SR equilibrium is not always the LR equilibrium. If an economy is operating at a SR equilibrium where Y > Yf, which of the following will occur in the process toward the new LR equilibrium when the economy corrects itself? | ||||||||||||||||

| 14. | From the Keynesians, Y = C + I + G + NX can be transformed into a theoretical model. In particular, assume that the consumption C = A + mpc (Y-T), where A is a constant, mpc is the marginal propensity to consume, Y is national income and T is income taxes. Suppose in the goods market equilibrium, aggregate expenditure = national income such that the two Y's will be the same from Y = A + mpc (Y-T) + I + G+ NX. . Suppose C = 400 + 0.75(Y â T). G = 100, I = 100, T = 100, and NX = 150, what is the Y in the goods market equilibrium? (All of the variables are in terms of million dollars) | ||

| 17. | Suppose the federal government needs to balance the budget, which means that when the government spending increases, taxes must increase equally. In this case, government spending multiplier is called the balanced-budget multiplier, defined as the increase in real GDP/increase in government spending. By following the example from the previous question, how mcuh is the balanced-budget multiplier? | ||||||||||||||||
