Econ 102 Flashcards
Federal Funds Rate
interest rate at which banks borrow from each other, decreased by fed to increase borrowing
money velocity equation
MV = PQ money*velocity = price level* output
things that shift money demand
increase in price level = increase MD increase in rGDP = increase MD increase technology (ATM) = decrease MD
how fed uses money supply
- Fed buys t-bills, money base increases instantly
- excess reserves rise and banks issue loans
- MS curve moves right, interest rate falls
When fed shifts MS out
- AD shifts out - some amount
- MD shifts out - same amount as AD
- self correcting mechanism, SRAS adjust to new LR level
- price level increases - same amount as MS and MD
3 goals of the fed
- full employment
- stable prices
- moderate long-term interest rates
monetarist policy
let the economy work itself out
expansionary monetary policy always leads to
inflation
Okun’s law
Actual U = Natural U - 1/2 (Output Gap)
modified for each economy
short run phillips curve
short-run tradeoff between inflation and unemployment, shifted by AS, found by plugging Okun’s law into SRAS
adaptive expectations
firms shift SRAS by the change in inflation of previous period, expected inflation always leads to inflation
rational expectations
firms shift SRAS immediately to new long run level
NAIRU
fed basically picks the rate of inflation, LRPC
classical model
wages and prices and perfectly flexible, like always being in the long run
hyperinflation
inflation of 50% in a month, real wages fall very quickly, people unwilling to make contracts
inflation tax
reduction in the real purchasing power of money holdings, caused by monetary policy
seignorage
change in the money supply
real seignorage
change in money supply / price level X 100
problems with deflation
reallocates wealth away from borrowers, debt deflation, money illusion, liquidity trap
debt deflation
reallocates value away from people who are already poor
money illusion
people don’t want to see their nominal wages fall
the liquidity trap
nominal interest rate will never fall below 0
slope of the PPF
-Px/Py
ToT
(Pt export / P1 export) / (Pt import / P1 import)
countries will trade as long as…
price level is between their autarkic opportunity costs
justifications for trade restrictions
national security, job creation, infant industry, anti-dumping (dumping: selling below cost of production to run out competitors)
Heckscher-Olin Theorem
US will specialize in industries that use lots of high-skilled workers, enhances inequality
balance of payments identity
current accounts = - financial accounts
dollar has appreciated if it
buys more ruble
real exchange rate
(Dollars / P us) / (Euros / P eu)
monetary rules
money targeting: hold money supply constant or increase supply by same percent every year
output targeting: keep output constant, use monetary supply only when supply is affected negatively
inflation targeting: keep prices stable
the taylor rule: ffr = 1 + 1.5 (inflation) + 0.5 (output gap)
