Answer: a recessionary gap
Explanation:
Equilibrium occurs where the planned aggregate expenditure is equals to the income Y.
Therefore, based on the question given, for this economy,
(2,000 + 0.8Y) = Y
Y - 0.8Y = 2000
0.2Y = 2000
Y = 2000/0.2
Y = 10,000.
Since potential output Y* is given as 11,000, then there's a recessionary gap since the actual output is lower than the potential output.
