Suppose Ford plans to produce 150,000 cars this year. The company expects to sell 135,000 cars this year. Suppose that at the end of the year, Ford has sold 140,000 cars. What do you expect to happen going forward?
Ford will produce more cars going forward and hire more people because there was an unplanned decrease in inventories.
Autonomous expenditure is a type of expenditure that does not depend on
GDP.
Increases in the price level will

a. Because contracts between workers and firms make some wages and prices "sticky" b. Because menu costs make some prices "sticky" c. Because firms are often slow to adjust wages, making them "sticky" d. All of the above
Why does the short-run aggregate supply curve (SRAS) slope upward?
a. Contracts keep wages "sticky". b. Prices of final goods rise more quickly than the prices of inputs. c. Firms and workers fail to predict changes in the price level.

If there are less inventories at the end of the year than expected:
a. total production was less than total spending. b. GDP < AE. c. inventories decrease. d. All of the above
If inventories decline by more than analysts predict they will decline, this implies that
actual investment spending was less than planned investment spending.
The difference between aggregate expenditure and aggregate demand is that:
aggregate demand shows the relationship between the price level and the level of aggregate expenditure when all other factors that affect aggregate expenditure are held constant; aggregate expenditure is a point on the aggregate demand curve at a specific price.
Holding all else constant, increases in firms' expectations of their future profitability and investment spending will make the ______________ shift to the_________?
aggregate demand; right

investment will fall
The marginal propensity to consume is:
a. The slope of the consumption function. b. The slope of the aggregate expenditure line.
When is the economy in a recession?
when the aggregate expenditure line intersects the 45-degree line at a level of GDP below potential GDP
Consumption spending is $16 million, planned investment spending is $4 million, unplanned investment spending is $2 million, government purchases are $6 million, and net export spending is $1 million. What is aggregate expenditure?
$27 million
Suppose booming economies in the BRIC nations (Brazil, Russia, India, and China) causes net exports (NX) to rise by $25 billion in the United States. If the change in equilibrium GDP for the US ends up being $250 billion, what was the value of the marginal propensity to save (MPS)?
0.1
Assume a $100 billion increase in planned investment results in an $400 billion increase in equilibrium real GDP. What is the value of the marginal propensity to consume in this economy?
0.75
Suppose booming economies in the BRIC nations (Brazil, Russia, India, and China) causes net exports (NX) to rise by $25 billion in the United States. If the change in equilibrium GDP for the US ends up being $250 billion, what was the value of the marginal propensity to consume (MPC)?

4
If prices become more 'sticky' due to longer contracts or more strict no-compete clauses, we would expect the short-run aggregate supply curve to:
Become flatter
Holding all else constant, if the economy's marginal propensity to consume increases, the aggregate expenditure function will:
Become steeper
How can government policies, holding all else constant, shift the aggregate demand curve to the right?
By increasing government purchases.

Which of the following statements is correct if real GDP in the United States declined by more during the 2007−2009 recession than did real GDP in Canada, China, and other trading partners of the United States?
Imports to the United States fell more than the U.S. exports, leading to an increase in net exports.
What is the effect on inventories, GDP, and employment when aggregate expenditure (total spending) exceeds GDP?
Inventories decrease, GDP increases, and employment increases.

Suppose a recession occurs as a result of a supply shock, and instead of the economy naturally working its way back to equilibrium, the government uses policy to shift the aggregate demand curve to fight the recession. Using policy this way would
bring real GDP back to potential GDP more quickly but would result in a permanently higher price level.
Labor productivity:
can increase when the level of capital per hour worked decreases.
Lack of investment in strong education and health care systems:
causes a deterioration in human capital and a decline in labor productivity.
The long-run aggregate supply curve is vertical because in the long run,
changes in the price level do not affect potential GDP, as potential GDP depends on the size of the labor force, capital stock, and technology.
