Acme Home Builders, Inc., has built 24 houses so far this year at a total cost to the company of $4.80 million. If the company builds a 25th house, its total cost will increase to $5.05 million. The marginal cost of the 25th house, if it is built, will equal
$250,000
a) similarity in NGDP and RGDP b) why favor RGDP
- Both provide a measurement for the money value of the final goods and services produced in an economy during a given period. - Real GDP is nominal GDP adjusted for changes in price levels to reflect changes in output only - Since changes in real GDP reflect only changes in quantities produced in an aggregate economy, macroeconomists argue that real GDP provides a more accurate representation of a country's economic activity
industrial machinery is an example of
- Factor of production that in the past was an output from the production process - Physical capital - Something that influences productivity
The following table presents information about a closed economy whose market for loanable funds is in equilibrium GDP: $7.3 trillion Consumer spending: $5.2 trillion Taxes - Transfers: $1.1 trillion Government Purchases: $0.7 trillion the quantity of loanable funds demanded is
1.4 trillion

If the Federal Open Markets Committee decides to increase the money supply, it
Creates dollars and uses them to purchase government bonds from the public
Suppose banks decide to hold more excess reserves relative to deposits. Other things he same, this action will cause the money supply to
Fall. To reduce the impact of this the Fed could buy Treasury bonds
Michael learns how to sew from his grandmother. This is an example of
Human capital, but not technological knowledge
A 5 percent reduction in the money supply will, according to classical economists, reduce prices 5 percent:
In the long run but lead to unemployment in the short run
How r is determined (liquidity theory)
MS curve is vertical: changes in r do not affect MS, which is fixed by the Fed MD curve is downward sloping: a fall in r increases the quantity of money demanded
Most economist believe the principle of monetary neutrality is
Mostly relevant to the long run
If the reserve requirement is 7 percent, a bank desired to hold no excess reserves, and it receives a new deposit of $200, it
Must increase required reserves by $14
tools of the Fed
Open Market Operations, Reserve Requirements, Discount rate new: Quantitative Easing, Interest on Reserves
A country reported nominal GDP of $100 billion in 2010 and $75 billion in 2009. It also reported a GDP deflator of 125 in 2010 and 120 in 2009. Between 2009 and 201
Real output and the price level both rose
public saving is
T - G
Large-scale asset purchases
The Fed's open market operations normally involve only the purchase of government securities, particularly those that are short-term. However, during the crisis, the Fed started two new, large-scale asset purchase programs (often referred to as LSAPs) to lower interest rates for particular types of credit.
money growth rate
The proportionate change per year in the nominal quantity of money.
Suppose that interest rates unexpectedly rise and that FineLine Corporation announces that revenues from last quarter were down but not as much as the public had anticipated they would be down. According to the efficient markets hypothesis, which of the following makes the price of FineLine Corporation Stock fall?
With rising interest rates most people will have less of an incentive to take out loans which will cause a slowing in economic activity on a macro scale. This slowing of economic activity is likely the cause of Fineline corporation's stock price fall - only the rising interest rate
private saving is
Y - T - C
what shifts AD curve
Y = C + Ig + G + NX changes in consumption, investment, government spending, and net exports
variables that influence money demand
Y, r, and P aka real income, interest rate, and price
bond
a certificate of indebtedness
Phillip's curve
a curve that shows the short-run trade-off between inflation and unemployment -- shifts in AS-AD model
misperceptions theory
a low-price level led some suppliers to think their relative prices have fallen, including a fall in production
Stagflation
a period of slow economic growth and high unemployment (stagnation) while prices rise (inflation)
quantity theory of money
a theory asserting that the quantity of money available determines the price level and that the growth rate in the quantity of money available determines the inflation rate
fixed interest rate
an interest rate that does not change-- what bondholders expect to earn
sticky price theory
an unexpectedly low price level leaves some firms with higher than desired prices, which depresses their sales and leads them to cut back production
sticky wage theory
an unexpectedly low price level raises the real wage, which causes firms to hire fewer workers and produce a smaller quantity of goods and services; nominal wages are slow to adjust to changing economic conditions
Unemployment in the long run will be
at its natural rate regardless of inflation
Why is the long-run aggregate supply curve vertical?
because of monetary neutrality, any change in price level does not affect the quantity of goods and services produced in the long run
AD shifters generally respond to
behavioral changes, not price changes
open markets expansionary policy
buy bonds, doing so puts funds directly in the loanable fund market, enabling banks to increase lending
unexpected inflation can
change unemployment in the short run (SRPC tradeoff), however the market will adapt and come to expect this infaltion
what shift long run aggregate supply
changes in labor, capital, human capital, natural resources, technology
included in M1 and M2
currency, demand deposits and other checkable deposits
Suppose you are deciding whether or not to buy a particular bond for $5,980.17. If you buy the bond and hold it for 5 years, then at that time you will receive a payment of $10,000. You will buy the bond today if the interest rate is a. no less than 9.48 percent. b. no greater than 9.48 percent. c. no less than 10.83 percent. d. no greater than 10.83 percent.
d. no greater than 10.83 percent. Because if it is higher than that then you want to save in the bank because you'll make more mula (11% percent for example would be more than 10,000 in 5 year) 5980.17 (1+r)^5 >10,000
wealth effect given a decrease in the price level
decrease in the price level raises the real value of money and makes you feel richer which encourages you to spend more
expansionary discount rate
decrease the rate, making it less expensive to borrow from the Fed, thus stimulating lending
reserve requirements expansionary policy
decrease the reserve ratio so that banks may lend more of their deposits. during so enables banks to increase lending
Phillips curve and expectations if the Fed reduces the rate of money growth and maintain it at a new lower rate, eventually expected inflation will ___ and the SRPC will shift ____
decrease, downward
contractionary policy ____ money supply
decreases
stockholders typically expect to earn what

during a presidential campaign, the incumbent argues that he should be reelected because nominal GDP grew by 12 percent during his 4-year term in office. You know that population grew by 4 percent over the period and that GDP deflator increased by 6% during the past 4 years. You should conclude that real GDP per person
grew, but by less than 12 percent
index funds typically have a
higher rate of return and lower cost than managed mutual funds
when the Fed increases the money supply and expands aggregate demand, it moves along the Phillips curve to a point with ___ inflation and ___ unemployment
higher, lower
Long Run Phillips Curve
illustrates the conclusion that unemployment does not depend on money growth and inflation in the long run
in the simple circular flow diagram, with households and firms, GDP can be computed as the
income received by households, in the form of wages, rent, business interest income, proprietors' income and profit
suppose the interest rate increases, while real income and prices remain the same/ What can we expect to happen to the demand for money?
increase
contractionary discount rate
increase the rate, making it more expensive to borrow from the Fed, thus discouraging lending
reserve requirements contractionary policy
increase the reserve ratio so that banks cannot lend as many of their deposits. doing so limits banks lending behavior
Over the last few decades, Americans have chosen to cook less at home and eat more at restaurants. This change in behavior, by itself, has
increased measured GDP by the value added by the restaurants preparation and serving of meals
expansionary policy ____ money supply
increases
temporary open market operations
involve repurchase and reverse repurchase agreements that are designed to temporarily add or drain reserves available to the banking system.
attach the income earned tot he use of one of the four key resources

things that may shift in LRAS curve
labor, capital, natural resources, technological knowledge
- Which way would the AD curve shift if there was a decrease in demand?
left
interest rate effect given a decrease in the price level
lower price level reduces the IR and encourages consumer to spend more on investment goods
according to classical theory, changes in money supply affect
nominal variables, not real
interest rate effect
occurs when a change in the price level leads to a change in interest rates and, therefore, in the quantity of aggregate demand
GDP components in public, private, international sectors
public: G private: C + IG international: XN
MV = PY

reflects how much wealth people want to hold in liquid form
- Which way would the AD Curve Shift if there is an increase in demand?
right
An decrease in the expected price level shifts SRAS
right
equity finance
sale of stock to raise money
what shifts short run aggregate supply
same as long run (factors), but also changes in expected price level
a higher interest rate induces people to
save more, so the supply of loanable funds slopes upward
If the government's expenditures exceeded its receipts, it would likely
sell bonds directly to the public
open markets contractionary policy
sell bonds. doing so removes bank reserves that could have been lent in the loanable funds market, preventing banks from lending
classical dichotomy
separation of real and nominal variables
AS/AD model used to explain
short-run fluctuations in economic activity arounds its long-term trend
aggregate supply curve
shows the quantity of goods and services that firms choose to produce and sell at each price level

If the nominal interest rate is 5% and the real interest rate is 7%, the the inflation rate is
-2%
GDP =
C + I + NX or C +IG + G + (EX - IM)
the theory of liquidity preferance
Keynes's theory that the interest rate (r) adjusts to bring money supply and money demand into balance
When the government's budget deficit increases the government is borrowing
More and public saving falls
Unemployment rate formula
natural rate - (actual inflation - expected inflation)
aggregate supply slopes upward for 3 reasons
sticky wage, sticky price, and misperceptions theory
monetary neutrality
the proposition that changes in the money supply do not affect real variables
In a closed economy, investment must be equal to private saving
true
social security payments are indexed for inflation using the CPI. A recent newspaper editorial claimed that SS recipients are harmed by years of low inflation because they do not receive as large a payment as they do in years in high inflation. Is the newspaper correct?
the newspaper editorial could be correct if the prices of the goods consumed by social security recipients change at a different rate than the price of the goods in the market basket used to compute the CPI
debt finance
the sale of bonds to raise money
When banks hold large amounts of reserves...
the scale of traditional open market operations is not sufficient to influence the short-term lending rate of commercial banks. unconventional monetary policy tools may be needed to support the flow of credit to households and businesses

true
T or F: Abjihit deposits $100 in a bank account that pays an annual interest rate of 5%. A year later, Abjihit withdraws his $105. If inflation was 2 percent during the year the money was deposited, then Abjihit's purchasing power has increased by 3 percent.
true
Three fourths of economist did not agree with what proposition
we should withdraw from NAFTA
AD slops downward for three key reasons
wealth, interest rate, and exchange rate effect
exchange rate effect
when a fall in the US price level reduces the IR, the value of the US dollar falls in the foreign exchange market. This depreciation of the dollar makes our goods appear cheaper to foreigners, so they buy more
