$14.3 trillion
Be able to solve the equation of exchange if given 3 variables.
(the money supply (M))(the velocity (V)) ≡ (the price level (P))(the Real GDP (Q)): MV ≡ PQ
The equation of exchange can be interpreted in different ways:
1. (The money supply)(velocity) = (the price level)(Real GDP): MV ≡ PQ 2. (The money supply)(velocity) = the GDP: MV ≡ GDP 3. Total spending or expenditures = the total sales revenues of business firms: MV ≡ PQ
What are the functions of the federal reserve?
1. Controlling the money supply 2. Supplying the economy with paper money (Federal Reserve notes) 3. Providing check-clearing services 4. Holding depository institutions' reserves 5. Supervising member banks 6. Serving as the government's banker 7. Serving as the lender of last resort 8. Handling the sale of U. S. Treasury securities (auctions)
Can't government purchases continually increase and so cause continued inflation?
1. Government purchases cannot go beyond either real or political limits so once they reach their limit, they can no longer increase 2. Increases in government purchases are not guaranteed to raise total expenditures because consumption may fall to the degree that government purchases have increased
If we drop the assumptions that V and Q are constant, changes in the price level depend on what 3 variables?
1. Money supply (M) 2. Velocity (V) 3. Real GDP (Q) P ≡ MV/Q

What shifts the AD curve in the simple quantity theory of money?
Aggregate demand depends on both the money supply (M) and velocity (V): 1&2. An increase in M or V = an increase in AD = shift the AD curve to the right 3&4. A decrease in M or V = a decrease in AD = shift the AD curve to the left BUT in the simple quantity theory of money, velocity is assumed to be constant. THUS, only changes in M can shift the AD curve.
What is the equation of exchange?
An identity stating that (the money supply (M))(the velocity (V)) ≡ (the price level (P))(the Real GDP (Q)): MV ≡ PQ

What is direct crowding out?
Example: The government spends more on public libraries, and individuals buy fewer books at bookstores
What is indirect crowding out?
Example: The government spends more on social programs and defense without increasing taxes; as a result, the size of the budget deficit increases. Consequently, the government must borrow more funds to finance the larger deficit. The increase in borrowing causes the demand for credit to rise (the demand for loanable funds), in turn causing the interest rate to rise. As a result, investment drops. Thus, more government spending indirectly leads to less investment spending

Describe and calculate how open market operations increase or decrease the money supply. Analyze the size of the effect using the money multiplier.
P. 334: (13-2b)
Simple Quantity Theory of Money: Describe the assumptions of the model, discuss how monetary policy will effect P and Q, and show these effects on an AD/AS model (note the odd shape of AS).

Monetarism: Describe the assumptions of the model, discuss how policy will influence the economy, and does the Fed create inflation?
P. 361: (a, b, c, d) Assumptions: 1. Velocity changes in a predictable way: MONETARISTS believe that velocity can and does change, but not randomly 2. Aggregate demand depends on the money supply and on velocity: MONETARISTS focus on the money supply (M) and velocity (V) the way Keynesians focus on the spending components of TE (C, I, G, EX, and IM), MONETARISTS argue that M and V change aggregate demand while Keynesians argue that C, I, G, EX, and IM changes aggregate demand 3. The SRAS curve is upward sloping: MONETARISTS believe Real GDP may change in the short run which would make the SRAS curve upward sloping, not vertical according to the simple quantity theory of money 4. The economy is self-regulating (prices and wages are flexible): MONETARISTS believe the economy can move itself out of a recessionary or inflationary gap and into long-run equilibrium, producing Natural Real GDP Effect: 1. The economy is self-regulating 2. Changes in velocity and the money supply can change aggregate demand 3. Changes in velocity and the money supply will change the price level and Real GDP in the short run but only the price level in the long run
One-shot inflation: demand-side induced
P. 364 1. The aggregate demand curve shifts right 2. As a result, the price level increases 3. Real GDP is greater than Natural Real GDP = the unemployment rate is less than the natural unemployment rate 4. As a result, wage rates rise 5. The short-run aggregate supply curve shifts left reaching long-run equilibrium
One-shot inflation: supply-side induced
P. 365 1. The short-run aggregate supply curve shifts left 2. As a result, the price level increases 3. Real GDP is less than Natural Real GDP = the unemployment rate is greater than the natural unemployment rate 4. As a result, some economists say that wage rates will fall 5. The short-run aggregate supply curve shifts right reaching long-run equilibrium
Changing one-shot inflation into continued inflation
P. 368 a. Continued inflation from the demand side of the economy b. Continued inflation from the supply side of the economy

P. 374: (a) P. 374: (b, c, d, e) 1. The Fed says that it will increase the growth rate of the money supply 2. If the expectations effect kick in immediately, then ... 3. Interest rates rise 4. The liquidity effect kicks in 5. As a result of what happened at point 4, the interest rate drops. The interest rate is now lower than it was at point 3.
What is data lag?
Policy makers are not aware of changes in the economy as soon as they happen Example: If the economy turns downward in January, the decline may not be apparent for 2-3 months
If given income and taxes, evaluate if a system is progressive or regressive.
Progressive: Suppose Davidson pay taxes at the rate of 15% on a taxable income of $20,000. When his taxable income rises to $30,000, he pays at a rate of 28%. When his income rises to $55,000, he pays at a rate of 31%. Regressive: Lowenstein's tax rate is 10% when her taxable income is $10,000. When her taxable income rises to $20,000, she pays at a rate of 8%.

The change in the interest rate due to a change in the price level
What is the liquidity effect?
The change in the interest rate due to a change in the supply of loanable funds
What is the laffer curve?
The curve, named after economist Arthur Laffer, that shows the relationship between tax rates and tax revenues; according to the laffer curve, as tax rates rise from zero, tax revenues rise, reach a maximum at some point, and then fall with further increases in tax rates

What is the simple quantity theory of money?
The theory which assumes that velocity (V) and Real GDP (Q) are constant and predicts that changes in the money supply (M) lead to strictly proportional changes in the price level (P)
What is public debt?
The total amount that the federal government owes its creditors
Suppose that currently the government charges 60% taxes on a base of $100 million. The government is considering stimulating the economy by cutting taxes. They estimate that if the tax rate were 50%, the tax base would be $120 million. Would this tax cut be worthwhile? Explain why or why not. Hint: A Laffer curve might help, but is not necessary.
This tax cut would not be worth while because the tax revenues would stay the same, $60 million.
What is the supply of loans?
Upward sloping, indicating that lenders will lend more funds as the interest rate rises; A Fed open market purchase increases reserves in the banking system and therefore increases the supply of loanable funds = the interest rate declines
If $4,800 billion worth of transactions occurs in a year (GDP) and the average money supply during the year is $800 billion (M), then a dollar must have been used an average of how many times (V) during the year to purchase goods and services?
V ≡ GDP/M V ≡ $4,800/$800 V ≡ 6 A dollar must have been used an average of 6 times during the year to purchase goods and services.
What is wait and see lag?
When policy makers become aware of a downturn in economic activity, they rarely enact counteractive measures immediately; instead, they usually adopt a relatively cautious wait-and-see attitude to be sure that the observed events are not just short-run phenomena
