a.) Deterioration in business expectations
b.) The 2008 global financial crisis leads to a decrease in wealth.
c.) Decrease in nominal wage rate
d.) Oil prices increase dramatically
e.) Deterioration in consumer expectations

a.) derive the equation for the aggregate expenditure (AE) curve
b.) What are the values of the slope and the vertical axis intercept of the AE curve
c.) what is the multiplier
d.) if investment rises to $450 billion, what will be the new equilibrium real GDP?
e.) what is the impact on balance of trade in (d)?

) Explain whether each of the following events shifts the short-run aggregate supply curve, the aggregate demand curve, both, or neither. For each event that does shift a curve draw a diagram to illustrate the effect on the economy (you don’t have to send me the graphs, but you should draw them on scratch paper for practice). Households decide to save a larger share of their income. Florida orange groves suffer a prolonged period of below-freezing temperatures. Increased job opportunities...

1. Explain why the long-run aggregate supply (LRAS) curve is vertical while the short-run aggregate supply (SRAS) curve slope upwards. List and discuss briefly the variables that could cause the LRAS and the SRAS curves to shift. For each variable, identify whether an increase in that variable will cause the curves (LRAS and SRAS curves) to shift to the right or to the left. 2.

Draw a diagram with an aggregate demand curve, a short-run aggregate supply curve, and a long-run aggregate supply curve, for an economy facing a recessionary gap. a) If the government does not intervene to close this gap, describe what will happen to this economy over time. Illustrate with a diagram. b) Describe the policies that the government could use to return the economy to long-run macroeconomic equilibrium, when it is facing a recessionary gap. Illustrate with a diagram. c) What...

Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output that firms supply can deviate from the natural level of output if the actual price level in the economy deviates from the expected price level. Several theories explain how this might happen. For example, the misperceptions theory asserts that changes in the price level can temporarily mislead firms about what is happening to their output prices. Consider a soybean farmer who...
