A. $200

B. Fall

C. Inflationary expenditure gap and employment levels are higher than the full employment level.

Explanation:

A. Equilibrium occurs where real output (Y) equals aggregate expenditures (AE), where AE = C + Ig + G + Xn.

Therefore the equilibrium value is:

Y = AE = C + Ig + G + Xn

= $120 + $60 + (-$10) + $30 = $200

B. If real GDP is $230 and the aggregate expenditures of $200 will result in positive unplanned inventory investment which means GDP will fall as firms respond to the inventory build-up by reducing output.

C. C + Ig + G + Xn

$170 + $60 + (-$10) + $30 = $250

Therefore since full-employment and full-capacity output in the economy is $230 there is an inflationary expenditure gap and employment levels are higher than the full employment level.
