Study the diagram below and answer the question.Which one of the following statements is false?  A Y1 represents the equilibrium level of income.B The curve labelled A = C + I shows the total of consumption and investment spending.C The curve labelled C shows the total of autonomous and induced consumption spending.D The point labelled D shows where savings equal investment.   In macroeconomic theory, total or aggregate spending is denoted by A and total or aggregateproduction of income by Y. Which one of the following statements is incorrect? A When A is greater than Y, there is disequilibrium and Y will tend to increase.B When A is equal to Y, there is equilibrium and Y will remain unchanged.C When A is less than Y, there is disequilibrium and Y will decrease.D When A is greater than Y, there is disequilibrium and A will decrease.
The following graph shows the total expenditure line (TE) for an economy where current equilibrium output is $350 billion and potential output is $600 billion. The economy is experiencing _________ (a contractionary gap, an inflationary gap) equal to $______ billion. To close the output gap, government purchases could _______ (increase, decrease) by _____ ($50, 150, 75) billion. Thus, the value of the multiplier for this economy is ___________ (0.7143, 0.5833, 0.4167, 1.6667, 0.6).
