Elements of the circular flow model
answer
households, goods markets, firms, factor markets, governments, and the rest of the world
question
Role of households in the circular flow model
answer
Sell the services of labor, capital, and land in factor markets, getting paid by firms for wages for labor services, interest for the use of capital, and rent for the use of land; these also buy consumer goods and services in goods markets

profits that are not distributed to households; part of the household sector's income; income that households save and lend back to firms
question
what happens in factor markets?
answer
households sell and firms buy the services of labor, capital, and land
question
what happens in goods markets?
answer
firms sell and households buy consumer goods and services; firms buy and sell new capital equipment; governments buy goods and services from firms; rest of the world imports and exports
question
consumption expenditure
answer
the total payment for goods and services sold by firms and bought by households in goods markets
question
Role of Firms in Circular Flow Model
answer
pay income to households in factor markets (Y); retain earnings (go into household sector's income); sell consumer goods in goods markets; buy and sell new capital equipment in goods markets
question
inventory
answer
what firms produce but don't sell; counted as investment in that it's like the firm buying goods from itself

answer
one method of measuring GDP; equals consumption expenditure + investment + government expenditure + net exports
question
aggregate income
answer
the total amount paid for the services of the factors of production used to produce final goods and services; wages, interest, rent, and profit

answer
a firm's profit before subtracting depreciation; one of the incomes included in the income approach to measuring GDP
question
The expenditure approach/method
answer
the sum of consumption expenditure (C), investment (I), government expenditure on goods and services (G), and net exports of goods and services (X-M); (red flows on page 499)
question
personal consumption expenditure
answer
the red flow C on page 499; the expenditures by US households on goods and services produced in the US and in the rest of the world; goods like soda/books and services like banking and legal advice;
question
Where do the purchases of new houses go?
answer
NOT personal consumption expenditures, but rather, as a part of investment
question
gross private domestic investment
answer
the red flow I; expenditure on capital equipment and buildings by firms and the additions to business inventories; also includes expenditures on new homes by households
question
the income approach/method
answer
measures GDP by summing the incomes that firms pay households for the services of the factors of production they hire (wages for labor, interest for capital, rent for land, and profit for entrepreneurship)

OFI
answer
net interest, rental income, corporate profits, and proprietors' income; included in income approach
question
net domestic income at factor cost
answer
the cost of factors of production used to produce final goods; sum of OFI and compensation of employees (expenditures on final goods are valued at market prices, which differ from factor cost because of indirect taxes and subsidies)
question
indirect tax
answer
a tax such as a sales tax or a tax on gasoline

market price includes ________, so ______?
answer
indirect taxes; so they make price exceed factor cost
question
subsidies make market price ________ than factor cost
answer
less than
question
To get from factor cost to market price, what do you do? How do you get net domestic income at market price?
answer
add indirect taxes and subtract subsidies to get net domestic income at market price
question
How to get from net income to gross income
answer
add depreciation
question
the gap between the two measures of GDP is what?
answer
statistical discrepancy; exists because all of the numbers are estimates
question
What to add to get GDP through the expenditure approach?
answer
personal consumption expenditures + gross private domestic investment + government expenditures on goods and services + net exports of goods and services
question
What to add to get GDP through the income method?
answer
compensation of employees + net interest + rental income + corporate profits + proprietor's income = net domestic income at factor cost
add net domestic income at factor cost to indirect taxes less subsidies to get net domestic income at market prices
add depreciation to net domestic income at market price
add net domestic income at factor cost to indirect taxes less subsidies to get net domestic income at market prices
add depreciation to net domestic income at market price
question
Real GDP
answer
the value of final goods and services produced in a given year when valued at the prices of a reference base year; reveals the change in production
question
nominal GDP
answer
the value of final goods and services produced in a given year when valued at the prices of that year
question
Calculating Real GDP
answer
For the base year, the real and nominal GDP is the same thing; calculate total expenditure in base year and then total expenditure in year you're comparing using the prices of the base year.
question
Main purposes for estimates of GDP
answer
to compare the standard of living over time and across countries
question
One method of comparing the standard of living over time is to ________?
answer
calculate real GDP per person in different years
question
Real GDP per person
answer
real GDP divided by the population; tells us the value of goods and services that the average person can enjoy; because it's real, we remove any influence that rising prices and a rising cost of living might have
question
Long-term trends in US real GDP
answer
real GDP per person in the US doubled between 1960 and 1988 and tripled between 1960 and 2016
question
potential GDP
answer
the maximum level of GDP that can be produced while avoiding shortages of labor, capital, land, and entrepreneurial ability that would bring rising inflation; is steady but not constant
question
Lucas wedge
answer
the dollar value of the accumulated gap between what real GDP per person would have been if the 1960s growth rate had persisted and what real GDP per person turned out to be; arose from the slow-down of productivity growth that began in the 1970s
question
the business cycle
answer
the fluctuations in the pace of expansion of real GDP; a periodic but irregular up-and-down movement of total production and other measures of economic activity
question
Two phases of the business cycle
answer
expansion and recession
question
two turning points in the business cycle
answer
peak and trough
question
expansion
answer
a period during which real GDP increases; in the early stages of this phase, real GDP returns to potential GDP and eventually exceeds potential GDP
question
recession
answer
a period during which real GDP decreases (has a negative growth rate) for at least two successive quarters
question
an expansion ends and a recession begins when?
answer
at the peak, or the highest level that real GDP has attained up to that time
question
a recession ends when?
answer
a a trough, when real GDP reaches a temporary low point and from which the next expansion
question
Problems in Using real GDP across countries
answer
must convert the currencies and must be evaluated at the same prices
question
market exchange rate
answer
the rate at which one currency will be exchanged for another. It is also regarded as the value of one country's currency in relation to another currency.
question
limitations to using GDP as a measure of standard of living (what it doesn't include that influences the standard of living)
answer
household production, underground economic activity, leisure time, and environmental quality
question
The omission of household production from GDP means that GDP does what to total production?
answer
underestimates total production and overestimates the growth rate of total production because some of the growth rate of market production (included in GDP) is a replacement for home production
question
underground economy
answer
the part of the economy that is purposefully hidden from the view of the government to avoid taxes and regulations or because the goods and services being produced are illegal; omitted from GDP
question
leisure time
answer
an economic good that adds to our economic well-being and the standard of living--the more leisure time, the better off we are
question
environmental quality
answer
while the resources used to protect the environment are valued as part of GDP, the cost of pollution is not subtracted from GDP
question
time-series graph
answer
measures time (in years, quarters, or months) on the x-axis and the variable or variables in which we are interested on the y-axis
question
cycle
answer
a tendency for a variable to alternate between upward and downward movements
question
trend
answer
a tendency for a variable to move in one general direction
question
Many macroeconomic variables like GDP and the average level of prices, have a ________ trend?
answer
upward
question
ratio scale
answer
intervals between measurements on the y axis aren't equal: for example, the vertical distance between 100 and 200 is greater than the distance between 300 and 400, showing that the variable is increasing at a decreasing rate over time
question
Chained-dollar real GDP
answer
The measure of real GDP calculated by the Bureau of Economic Analysis; three steps from textbook on pages 512-513 to explain in detail the process, but the three steps are 1) value production in the prices of adjacent years 2) find the average of the two price changes and 3) link (chain) back to the reference year
