-one of the very broad definitions of money includes the amount of available credit on credit cards as a part of the money supply -no rules for deciding what is and is not money
how banks created money
gold was used as money but was hard to carry around, so people kept their gold with goldsmiths for safekeeping. receipts were issued to the depositor in the form of paper money. goldsmiths found that people didn't come often to withdraw gold, but instead exchanged their paper receipts. people started doubting the safety of goldsmiths and demanded their gold back from the vault.

what happens to the supply of money when loans becomes deposits?
the supply of money increases.

required reserve ratio x total deposits
what happens to the money supply when there's an increase in bank reserves
there is a greater than one-for-one increase in the money supply
money multiplier

money multiplier formula
1/required reserve ratio
when was the federal reserves system founded
1913 by an act of congress
who is the most important group within the federal reserve system
the board of governors
what does it mean when the fed is an independent agency?
it does not take orders from the president or congress

open market desk
the office in new york federal reserve bank from which government securities are bought and sold by the fed
lender of last resort
provides funds to troubled banks that cannot find any other source of funds
the amount of money you want to hold is
-positively related to the size of your transactions -negatively related to the interest rate (the opportunity cost of holding money)
what happens to the opportunity cost of holding money as the interest rate decreases?
the opportunity cost decreases as well.
what happens to the money demand curve when there's an increase in transactions?
the money demand curve shifts to the right
interest-bearing securities are issued by...
firms, and the government seeking to borrow money
what are securities issued with?
a face value and fixed payments, or coupons, over time.
what happens to the prices of existing securities when interest rates rise?
the price of existing securities fall
what happens when the fed increases the money supply?
the interest rate falls
what does the federal reserve determine?
the federal reserve determines the supply of bank reserves
how does the federal reserve control the supply of bank reserves
they buy and sell securities
what happens to the curve when you buy securities?
the curve shifts to the right
what happens to the curve when you sell securities?
the curve shifts to the left
feds in march 2008
the fed became an active participant in the private banking system in response to the financial troubles faced by many large financial institutions
feds in november 2008
the fed began buying securities of fannie mae and freddie mac
feds in september 2012
the fed opted to buy mortgage-backed securities and long-term government bonds to the tune of $85 billion per month
traditional approach to monetary policy
managing the fed funds rate, now near the zero bound
balance sheet approach to monetary policy
adjusting size, maturity, composition
forward guidance approach to monetary policy
aimed at informing the public and markets to align expectations of prospects for short-term interests and balance sheet policies with those of FOMC
what can happen if interest on reserves are paid?
the fed could expand its balance sheet without having the funds rate fall to zero
in theory, how does fomc increase the floor on funds rate?
by raising the ioer
federal funds rate
the rate banks are charged to borrow reserves from other banks
prime rate
a benchmark that banks often use in quoting interest rates to their customers
aggregate supply (as)
the total supply of all goods and services in an economy
aggregate supply (as) curve
a graph that shows the relationship between the aggregate quantity of output supplied by all firms in an economy and the overall price level
aggregate supply curve in the short run
positive slope (slopes upward and to the right)
the curve at low levels of aggregate output
the curve is fairly flat
what happens to the curve when the economy approaches capacity?
the curve becomes nearly vertical
why does the aggregate supply curve have a positive slope
wages are a large faction of total costs, and wage changes lag behind price changes.
axises on the aggregate supply curve
x axis: aggregate output (income) (y)
y axis: price level (p)
why does the aggregate supply curve have a curving shape
increased demand for labor and output can only be met with an increase in prices
what does it mean when the curve has an undefined slope (vertical slope)?
the curve reached the economy's maximum output
what shifts the AS curve?
increase or decrease in costs of products
cost shock, or supply shock
a change in costs that shifts in the short-run aggregate supply curve
aggregate demand (ad) curve
a curve that shows the relationship between the price level and the quantity of real GDP demanded by households, firms, and the government
planned expenditure and the interest rate
AE = C + I + G
what happens to the total planned spending as the interest rate increases
the total planned spending increases as well
a high interest rate [blank] planned investment
discourages
planned aggregate expenditure at every level of income [blank]
falls
a decrease in AE [blank] equilibrium output by a multiple of the initial decrease in I
lower
IS curve
relationship between aggregate output and the interest rate in the goods market
with the interest rate fixed, an increase in government spending (g) [blank] AE and thus Y in equilibrium
increases
relationship between output and interest rate
negative relationship
why is there a negative relationship between output and interest rate?
planned investment depends negatively on the interest rate
what happens to the IS curve when the government spending increases
there is a shift to the right, assuming the interest rate is fixed
fed rule equation
r = aY +bP + yZ (Z includes economic factors that lie outside the model)
fed rule
equation that shows how the Fed's interest rate decision depends on the state of the economy
the intersection of the fed rule and IS curve
equilibrium values of output and the interest rate for given values of government spending (g), the price levels (p), and the factors in Z
why does the AD curve fall when P increases?
higher prices leads the feds to raise r, which decreases I, thus Y
what happens to aggregate output when interest rates increase?
aggregate output falls when interest rates increase
aggregate output and aggregate price level are determined by...
the intersection of the AS and AD curves
real wealth effect
the change in consumption brought about by a change in real wealth that results from a change in the price level (contributes to a downward-sloping curve)
what happens to the equilibrium price level and output when the AD curve shifts to the right?
the curve increases
what does it mean when the price levels increase?
wages are responding to the price change. if wages fully adjust, the output will go back to its original position (potential gdp)
