The rate of output and planned expenditures for the economy of Timbuktu are shown in the following table:

              Total Output              Planned Aggregate Expenditures                                                                  (Two-Sector Economy)
(Real GDP in billion dollars)                          (in billions)

                   5,000                                                5,250
                   5,500                                                5,500
                   6,000                                                5,750
                   6,500                                                6,000
                   7,000                                                6,250

  a) If the current output rate is $5.0 trillion, what will tend to happen to business inventories, future output, and employment? 

 b)  If the current output rate is $6.5 trillion, what will tend to happen to inventories, future output and employment?

 c)  What is the equilibrium rate of income/output of Timbuktu economy? 

 d) If the economy's full employment rate of output is $6.0 trillion, what will happen to the unemployment rate assuming that  it will persist into the future?

 e)  What would happen to the equilibrium level of output/income if there will be an autonomous increase in investment of $250 billion?
