Given an economy is currently producing at $1.2T rGDP, natural rGDP is $1.3T, and the MPC is 0.9, then the multiplier for increases in aggregate expenditures is:

a)What will the multiplier be given the MPS values below? Fill in the table with your answers.  Instructions: round your answers to 2 decimal places.                               MPS                     Multiplier                 0.0                                     0.4                   0.5                  1.0   b) What will the multiplier be given the MPC values below? Fill in the table with your anwers.                                MPC                    Multiplier                                 1.0                                  0.9                                0.75                                0.5                                0   c) How much of a change in GDP will result if firms increase their level of investment by $ 8 billion and the MPC is 0.80? ( Enter your answers as whole numbers) How much of a change in GDP will result if firms incresese their level of investment by $ 8 billion and the MPC instead is 0.67?

If the consumption function is C = $800 billion + 0.8Y,   a. what is the MPC?          __   b. how large is autonomous consumption?        $ __ billion    c. how much do consumers spend with incomes of $4 trillion?        $  __billion    d. how much do they save?        $ __ billion

Calculate MPC, MPS and the Multiplier if consumption expenditure increases by $4,000 as a result of increase in income from $40,000 to $46,000.
