- Consider a Keynesian Cross Model with following features,
Consumption Function: C = C0 + b(Y-T)
Tax Function: T = T0 + tY
Income Identity: Y = C + I0 + G0
Where, C = Consumption; Y = Real Income; T = Tax; I = Investment;
G = Government Expenditure; b = Parameter; t = Tax Rate
(The subscript 0 (zero) indicates that the concerned variable is autonomous)
If b = 0.7 and t = 0.2, value of the Keynesian multiplier is ________ (round off to 2 decimal places).- IIT JAM EN - 2024
