Given the following information about each economy , either calculate the missing variable or determine that it cannot be calculated . [LO 7.2,7.3] a. If C=\$20.1 billion, I=\$3.5 billion G=\$5.2 billion, and NX=-\$1 billion, what is total income ? b. If total income is $1 trillion G=\$0.3 tr trillion , and C=\$0.5 trillion , what is I? c. If total expenditure is $675 billion, C=\$433 billion , I = $105 billion , and G=\$75 billion , what is NX ? How much are exports ? How much are imports?
Suppose that consumer spending initially rises by $5 billion for every 1 percent rise in household wealth and that investment spending initially rises by $20 billion for every 1 percentage point fall in the real interest rate. Also assume that the economy�s multiplier is 3. If household wealth falls by 6 percent because of declining house values, and the real interest rate falls by 2 percentage points, in what direction and by how much will the aggregate demand curve initially shift at each price level? The aggregate demand curve will shift_____ by $____ billion. In what direction and by how much will it eventually shift? The aggregate demand curve will shift_____ by $____ billion..

Suppose a closed economy with no government spending or taxing initially. Suppose also that intended investment is equal to 100 and the aggregate consumption function is given by C = 250 + 0.75Y. And suppose that, if at full employment, the economy would produce an output and income of 3500
By how much would the government need to raise spending (G) to bring the economy to full employment?

- ADVANCED ANALYSIS Assume that the consumption schedule for a private closed economy is such that consumption is: C = 100 + 0.75Y Assume further that planned investment Ig is independent of the level of real GDP and constant at Ig = 50.
