The Following Questions include graphs that I cannot upload if you can please help with visuals also, thank you. The following graph shows the consumption function (C) for a hypothetical private closed economy and a 45-degree line along which aggregate expenditure equals real GDP (AE=Y). Recall that a private closed economy does not have government and does not trade with the rest of the world (so G=0 and (X-M)=0). In a private closed economy, real GDP is equal to disposable income. At the current real interest rate, the level of investment in this economy is equal to $50 billion at each level of real GDP. Use the blue line (circle symbols) to plot this economy's initial aggregate expenditure line, (C + I). Then, use the black point (X symbol) to indicate this economy's initial equilibrium output. Dashed drop lines will automatically extend to both axes. (Hint: You can see two of the coordinates along the consumption function by mousing over the green triangles on the graph.) At the…
Use the graph to answer the following questions:
a)what is the value of the MPC?
b)what is the value of the MPS?

Suppose that for each one-percentage-point increase in the interest rate, the level of investment spending declines by $1.25 billion.

According to the change you made to the loanable funds market in the previous scenario, the increase in government purchases causes the interest
rate in the money market to from 6% to
%. The change in the interest rate causes the level of investment spending to
$
billion.

After the multiplier effect is accounted for, the change in investment spending will cause the quantity of output demanded to
$
billion at each price level. The impact of an increase in government purchases on the interest rate and the level of investment
spending is known as the

The host of the podcast is facilitating their debate over saving incentives. The following dialogue represents a portion of the transcript of their discussion: Rina: I think it's safe to say that, in general, the savings rate of households in today's economy is much lower than it really needs to be to sustain an improvement in living standards. Musashi: I think a switch from the income tax to a consumption tax would bring growth in living standards. Rina: You really think households would change their saving behavior enough in response to this to make a difference? Because I don't.
