JNU SSS 2014 Question 36: Keynesian cross and the multiplier
Suppose in an economy in any period t the aggregate value of output is Y(t)=C(t)+I(t), the sum of aggregate consumption and investment expenditures.
Suppose C(t)=0⋅6Y(t)+0⋅3Y(t−1) and I(t)=1000 for all t. What is the only value of output which, once attained in this economy, will continue to persist over time?

Plain-text version
Suppose in an economy in any period t the aggregate value of output is Y(t) = C(t) + I(t), the sum of aggregate consumption and investment expenditures. Suppose C(t) = 0·6Y(t) + 0·3Y(t - 1) and I(t) = 1000 for all t. What is the only value of output which, once attained in this economy, will continue to persist over time? (A) 2000 (B) 2500 (C) 4000 (D) 10000
Also written as: Suppose in an economy in any period t the aggregate value of output is Y(t) = C(t) + I(t), the sum of aggregate consumption and investment expenditures. Suppose C(t) = 0*6Y(t) + 0*3Y(t - 1) and I(t) = 1000 for all t. What is the only value of output which, once attained in this economy, will continue to persist over time?
