7. The equilibrium condition in the Keynesian-cross analysis in a closed economy is:

actual expenditure equals planned expenditure.
actual saving equals actual investment. 1 2 3 4 5

9. downward and to the left. upward and to the right.
An increase in taxes shifts the IS curve, drawn with income along the horizontal axis and the interest rate along the vertical axis:
downward and to the left.
upward and to the right.
upward and to the left.
downward and to the right. 1 2 3 4 5

10. downward and to the right. downward and to the left.
A decrease in the price level, holding nominal money supply constant, will shift the LM curve:
upward and to the right.
downward and to the right.
downward and to the left.
upward and to the left. 1 2 3 4 5

11. In the Keynesian-cross analysis, if the consumption function is given by C = (Y – T), and planned investment is 100, G is 100, and T is 100, then equilibrium Y is:
350
400
600
750 1 2 3 4 5

12. Based on the graph, starting from equilibrium at interest rate r1 and income Y1, a tax cut would generate the new equilibrium combination of interest rate and income:
r2, Y2
r3, Y2
r2, Y3
r3, Y3 1 2 3 4 5

13. increase; LM2 decrease; LM2 increase; LM3 decrease; LM3
Based on the graph, starting from equilibrium at interest rate r3 ,income Y2, IS1, and LM1, if there is an increase in government spending that shifts the IS curve to IS2, then in order to keep the interest rate constant the Federal Reserve should _____ the money supply shifting to _____.
increase; LM2
decrease; LM2
increase; LM3
decrease; LM3 1 2 3 4 5

14. Based on the graph, if the economy starts from a short-term equilibrium at A, then the long-run equilibrium will be at ____ with a _____ price level.
B; higher
B; lower
C; higher
C; lower 1 2 3 4 5

15. rise in the real interest rate and a fall in investment.
A tax cut combined with tight money, as was the case in the United States in the early 1980s, should lead to a:
rise in the real interest rate and a fall in investment.

fall in both the real interest rate and investment. 1 2 3 4 5
