autonomous
In the aggregate model, ___ has both an autonomous component and an induced component
consumption spending

If inventories decline by more than analysts predict they will decline, this implies that
actual investment spending was less than planned investment spending
An unplanned increase in inventories results from
actual investment that is greater than planned investment
As a result of slow economic growth in 2011, many companies including Cisco Systems, Lockheed Martin, and Cracker Barrel Old Country Store cut production and employment as a result of the sluggish growth in the total amount of spending in the economy. The total amount of spending in the economy is known as
aggregate expenditure

aggregate expenditure is equal to GDP
Firms in a small economy planned that inventories would grow over the past year by $500,000. Over that year, inventories did grow by exactly $500,000. This implies that
aggregate expenditure that year was equal to GDP that year
Firms in a small economy planned that inventories would grow over the past year by $300,000. Over that year, inventories actually grew by $400,000. This implies that
aggregate expenditure that year was less than GDP that year
If firms sell exactly what they expected to sell, what won't occur
aggregate expenditure will be greater than GDP
A decrease in consumer confidence can put your job at risk if
aggregate expenditures fall
A stock market boom which causes stock prices to rise should cause
an increase in consumption spending
What causes a direct increase in consumption spending
an increase in disposable income
What raises consumer expenditures?
an increase in expected future income
Investment spending will increase when
business cash flow increases
Concerned that its dependence on sales of microprocessors to computer firms would make it vulnerable to sharp sales declines during the recession of 2007-2009, Intel began to develop memory chips that could be used in portable consumer electronic devices such as cell phones. One reason that Intel chose to branch out from producing microprocessors for computers is that
computers are durable goods and spending on computers follows the business cycle
The multiplier is calculated as the
change in real GDP/ change in autonomous expenditure
National income=
consumption+saving+taxes
Investment spending ____ during a recession, and _____ during an expansion
declines; increases
