Consider an economy with a real income of $10,000, consumption spending of $7,000, and net tax revenue of $2,000.
a. Calculate domestic private saving and Suppose government spending is $2,000. What is the public saving?
b. Continuing from part last part, what is national saving?

c Continuing from part b, suppose net foreign investment is -$3,000. What is private domestic investment spending?

Expert Solution

(a) Domestic Private Saving = Income - Consumption - Tax Revenue

= 10,000 - 7000 - 2000 = $1000

=> Domestic Private Saving = $1000

Public Saving = Tax Revenue - Government Spending

= 2000 - 2000 = $0

=> Public Saving = $0

(b) National Saving = Public Saving + Private Saving = 0 + 1000 = $1000

=> National Saving = $1000

(c) Mathematically At equilibrium Y = C + I + G + NX

=> I = Y - C - G - NX -------------------(1)

where C = consumption. I = Investment , G = Government Expenditure and NX = Net Exports

S(National Saving) = Private Saving + Public Saving = (Y - C - T) + T - G = Y - C - G ------------------(2)

From (1) and (2) We have

I(Domestic investment) = National Saving - NX

and NX = Net Foreign Investment

=> Domestic investment = National Saving - Net Foreign Investment

= 1000 - (-3000) = $4000

=> Domestic investment = $4000

List the four non-income determinants of consumption and spending

Consider a hypothetical economy with autonomous consumption spending equal to 100 billion dollars, a marginal propensity to consume of 0.8

Consider a hypothetical economy with autonomous consumption spending equal to 100 billion dollars, a marginal propensity to consume of 0.8, private investment spending of 160 billion dollars, government spending of 140 billion dollars, a balanced budget, and balanced trade (i.e. exports and imports are equal). Write a short essay comparing the effects (1) on the government budget and (2) on the equilibrium level of income in the economy of (i) a 5 billion dollar increase in government spending and...

Consider a small open economy where workers care about their real consumption wage. Assume, in addition, that the Marshall-Lerner condition holds. This economy starts at the longrun equilibrium and suddenly experiences the following shock. Households get easier access to mortgages and, as a result, the savings rate falls in this economy. What will be the effect of this shock on the medium run equilibrium in this economy? Describe the changes in the equilibrium employment, RER, Trade Balance and real consumption...
