5. The slowing of the U.S. economy in early 2008 and the financial crisis in the fall lead to the passage of two bills in Congress which equaled a $700 billion stimulus to the economy. The 2008 Real GDP equaled $11.7 trillion. a. Assuming the MPC =2/3, calculate the total change in Real GDP expected from the $700 billion stimulus over time. b. Illustrate this change with an Income-Expenditure graph. Draw the original 2008 planned Aggregate Expenditure function with the original Real GDP, then add the post-stimulus planned AE with the new Real GDP. Identif the AEs as 1 and 2 and the numbered Real GDPs at their equilibrium levels.
