70) Which of the following statements concerning Keynesian analysis are true?
A) Keynes's analysis started with the recognition that the total quantity demanded of an economy's output was the sum of four types of spending: consumer expenditure, planned investment spending, government spending, and net exports.
B) Keynes recognized that equilibrium would occur in the economy when total quantity of output supplied (aggregate output produced, Y) equals quantity of output demanded (Yad), that is, when Y = Yad.
C) Keynes's analysis involves explaining why aggregate output is at a certain level by understanding what factors affect each component of aggregate demand and how the sum of these components could add up to an output smaller than the economy is capable of producing, resulting in less than full employment.
D) All of the above are true.
75) Keynes assumed that the price level was fixed because

C) fixed; gross D) fixed; inventory
85) The multiplier concept is important in the Keynesian model because
