a).
consider the given problem here the “MPC” is given by “z=0.5”. Now, if the autonomous spending increases by “$2000”, => in the 1st round the “Y” will increase by the same amount. Now, in the 2nd round “Y” will increase the “C=consumption by “MPC*dY” amount that will further increase the “AE”, => “Y” will increase by “MPC*dY” amount.
Now, in the 3rd round increase in “Y” will further increase “C” by “MPC*dY = MPC^2*d(AE)”, => “Y” will further increases by “MPC^2*d(AE)” and so on. Consider the following table.
b).
So,
dY = ($2000 + 0.5*$2000 + 0.5^2*$2000+…….) = ($2000/1- 0.5) = $4000, => dY=$4,000.
c).
Now, consider the process of deposit creation, there is a deposit of “$30,000” and the reserve ratio is given by, “v=0.2”, => the bank will “reserve of amount “$30,000*0.2=$6,000” and will make a loan of amount “$30,000*(1-0.2)=$24,000”. Now, because there is no cash holding, => the deposit in the 2nd round is “$24,000” and the “R=0.2*$24,000 = $4,800”, => the loans is given by, “$24,000*0.8=$19,200”. So, in this way we can derive all the “deposits”, “reserve” and “loans”. Consider the following table.
d).
So, here the sum of the 1st column is given by.
=> dY = [$30,000 + (1-0.2)* $30,000 + (1-0.2)^2* $30,000+ (1-0.2)^3* $30,000+…….].
=> dY = [$30,000 + 0.8* $30,000 + 0.8^2* $30,000+ 0.8^3* $30,000+…….].
=> dY = [$30,000 + 0.8* $30,000 + 0.8^2* $30,000+ 0.8^3* $30,000+…….]
=> dY = $30,000/(1-0.8) = $150,000, => dY = $150,000.
Thus the total change in deposit is given by,”$150,000”.
e).
a reserve ratio for the deposit multiplier is similar to “the MPC” for the simple multiplier. So, here the correct answer is “D”.

The following table shows alternative hypothetical economies and the relevant values for the marginal propensity to consume out of disposable income (MPC), the net tax rate (t), and the marginal propensity to import (m). a. Recall that z, the marginal propensity to spend out of national income, is given by the simple expression Z-MPC(1-1)-m. By using this expression, compute z and the simple multiplier for each of the economies and fill in the table. (Round your response to two decimal...
10.) An economy has a marginal propensity to consume and Y* , income-expenditure equilibrium GDP, equals $500 billion. Given an autonomous increase in plannėd investment of $10 billion, show the rounds of increased spending that take place by completing the accompanying table. The first and second rows are filled in for you. In the first row the increase of planned investment spending of $10 billion raises real GDP and YD by $10 billion, leading to an increase in consumer spending...
