    Question

    Consider a Keynesian Cross Model with following features, Consumption Function: C= C0 + b (Y – T)

    Tax Function: T = T0 + tY

    Income Identity: Y = C + Io + Go

    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_________?

    A 2.27 Correct Answer Incorrect Answer
    B 2.37 Correct Answer Incorrect Answer
    C 3.27 Correct Answer Incorrect Answer
    D 3.37 Correct Answer Incorrect Answer

    Solution

    Multiplier = 1/ (1-b+bt) = 1/(1-0.7+(0.7*0.2)) = 2.27
