Question #60991
2.Assume the following information represents the National Income Model of a hypothetical economy.
Y = C + I + G,C = a + b(Y – T),T = d + tY, I = I0,G = G0
Where a > 0; 0 < b < 1,d > 0; 0 < t < 1,T = Taxes, I = Investment ,G = Government Expenditure
Explain the economic interpretation of the parameters a,b,d and t.
Find the expression of equilibrium income, consumption and taxes
Y = C + I + G,C = a + b(Y – T),T = d + tY, I = I0,G = G0
Where a > 0; 0 < b < 1,d > 0; 0 < t < 1,T = Taxes, I = Investment ,G = Government Expenditure
Explain the economic interpretation of the parameters a,b,d and t.
Find the expression of equilibrium income, consumption and taxes
Expert's answer
a – autonomous consumption, which is independent on disposable income;
b – slope of the consumption function;
d – constant autonomous lump-sum tax;
t – rate/proportion of income tax.
An expression, which determines income, consumption and taxes at equilibrium:
Y̅ = 1/1-b x (a - bT + I + G)
b – slope of the consumption function;
d – constant autonomous lump-sum tax;
t – rate/proportion of income tax.
An expression, which determines income, consumption and taxes at equilibrium:
Y̅ = 1/1-b x (a - bT + I + G)

The equations describing desired consumption (C^d) and desired Investment (I^d) are given as follows: C=C0+C1(Y-T)-C2r I= t0 +tY I =I0 -I1r. Where Y= disposable Income C0, C1, C2 I0 and I1 are positive numbers Hint: Y=C^d +I^d +G is provide an expression for the Iscane using appropriate illustrations, explain the relationship between taxes and the desired Capital Stock

in a certain economy marginal propensity to save is 0.2 and the autonomous consumption is 400 a)formulate consumption function b)if the government expenditure is to increase were to increase by 50% what would be the resultant change in national income
