A budget surplus increases national saving (increases public savings which in turn increases national saving) & the supply of loanable fund which reduces the equilibrium interest rate & increases the equilibrium quantity of loanable funds & investment.

Imagine that the government starts with a balanced budget & then, because of a decrease in government spending (&/or increase in taxes), starts running a budget surplus. Draw a diagram showing the changes in equilibrium. What happens to the equilibrium values of the interest rate & investment?

John Maynard Keynes

Who is credited for the original development of the model of aggregate demand & aggregate supply?

(total income - taxes - consumption) + (taxes - government purchases) = investment (1,000 - 150 - C) + (150 - 200) = 250 (850 - C) + (-50) = 250 800 - C = 250 - C = -550 C = 550 Private Saving = 1,000 - 150 - 550 = $300

The Board of Governors runs the Federal Reserve. It has seven members who are appointed by the U.S. president with the advice & consent of the Senate. The voting members of the Federal Open Market Committee include the 7 members of the Board of Governors & 5 of the 12 regional bank presidents, rotated among the 12 regional presidents, always including the president of the New York Fed. The chair of the BOG also serves as chair of the FOMC meets about every six weeks in Washington, D.C. to discuss the condition of the economy & to consider changes in monetary policy.

Compare the Board of Governors & the Federal Open Market Committee

Labor force = 158.9 + 5.8 = 164.7 million Unemployment rate = 5.8 / 164.7 = 0.035 x 100 = 3.52% Adult population = 158.9 + 5.8 + 99.7 = 264.4

Compute the labor force, unemployment rate, adult population, & labor force participation rate using this data

Esther pays James $50 to mow her lawn. a) What happens with GDP? b) Will your answer to the previous question change if Esther & James get married?

When the price level increases, the purchasing power of money held on hand & in bank accounts declines. This decline makes people feel less wealthy so that they lend less. The reduction in lending causes the interest rate to rise. The rise in interest rates discourages spending on investment goods so that the aggregate quantity of goods & services demanded decreases. As the interest rate increases, the supply of dollars in the market for foreign-currency exchange falls as people wish to purchase fewer foreign assets. This makes the dollar appreciate which decreases net exports.

Explain how an increase in the price level changes interest rates. How does this change in interest rates lead to changes in investment & net exports?

In response to tax reform, households are encouraged to save more than they previously saved.

Imagine that in 2019 the economy is in long-run equilibrium. Then stock prices rise more than expected & stay high for some time. How is the new long-run equilibrium different from the original one?

The expected price level rises. New wage contracts are negotiated at higher wages.

Imagine that in 2019 the economy is in long-run equilibrium. Then stock prices rise more than expected & stay high for some time. In the long run, what happens to the expected price level & what impact does this have on wages bargaining?

The economic system of a particular country determines how resources are allocated. Countries with a market-based economy produce a more efficient allocation of resources. In addition, the desire of firms to earn a profit within this type of system plays an important role beyond the profit itself. This can cause the economy to grow. On the other hand, countries with a command-based system often either control the means of production or determine prices & quantities that are produces through some type of central planning board. These systems produce an inefficient allocation of resources because central planners lack the necessary specialized knowledge to allocate resources efficiently. An example of a command-based economy is North Korea while that of a market economy is South Korea. The differences in economic well-being are telling.

Marcus was laid off from the local plant of a major automaker when the firm began retooling to produce a new model car. Marcus knows he will be called back to work as soon as the model changeover is completed, & he also knows it is unlikely that he would be able to find a job for the period he is laid off; so, although he is available to work, he is not seeking a job.

Quantity of output = natural rate of output + a(actual price level - expected price level)

Write the mathematical expression that summarizes the three alternative explanations for the upward slope of the short run aggregate supply curve.

a) Real Interest Rate = Nominal Interest Rate - Inflation Rate Case 1: Real Interest Rate = 12% - 1% = 11% Case 2: Real Interest Rate = 24% - 12% = 12% The real interest rate is highest in CASE 2 b) Case 1: Interest Income = Nominal Rate x Amount Deposited = 12% x 10,000 = $1,200 Taxes paid on Interest Income = Tax Rate x Interest Income = 20% x $1,200 $240 Case 2: Interest Income = Nominal Rate x Amount Deposited = 24% x 10,000 = $2,400 Taxes paid on Interest Income = Tax Rate x Interest Income = 20% x $2,400 = $480 The most taxes paid is in CASE 2 c) Case 1: After-tax nominal interest rate = 0.80 x 12% = 9.6% After-tax real interest rate = 9.6% - 1% = 8.6% Case 2: After-tax nominal interest rate = 0.80 x 24% = 19.2% After-tax real interest rate = 19.2% - 12% = 7.2%

You deposit $10,000 in the bank for one year. CASE 1: Inflation = 1%, Nominal interest rate = 12% CASE 2: Inflation = 12%, Nominal interest rate = 24% a) In which case is the real interest rate the highest? b) In which case do you pay the most taxes on interest income? c) Compute the after-tax nominal interest rate, then subtract inflation to get the after-tax real interest rate for both cases.

a) Public Savings = Tax Revenue - Government Spending = -$1.2 trillion (Whenever there is a budget deficit, it simply means there is negative public saving (probably due to borrowing) b) Tax Revenue = $1.3 trillion (Public Savings = Tax Revenue - Government Spending; can be rearranged as Tax Revenue = Public Savings + Government Spending = -1.2 + 2.5 = $1.3 trillion) c) Private Savings = $4.7 trillion (Private Saving = Y - C - T = 19 - 13 - 1.3 = $4.7 trillion) d) National Saving = $3.5 trillion (National Saving = Private Saving + Public Saving = $4.7 trillion + (-$1.2 trillion) = $3.5 trillion) e) Investment = National Saving = $3.5 trillion

You have the following information: GDP = $19 trillion, Consumption = $13 trillion, Government Spending = $2.5 trillion, & Budget Deficit = $1.2 trillion. Find the following: a) Public saving b) Tax revenue c) Private saving d) National saving e) Investment (Hint: Budget Deficit occurs when G > T)

a) 9,240 x (251.1 / 130.7) = $17,751.8 = (35,830 - 17,751.80 / 17,751.80) x 100 = 101.84% 1,908 x (251.1 / 130.7) = $3,665.60 = (10,230 - 3,665.60 / 3,665.60) x 100 = 179.1% $906 x (251.1 / 130.7) = $1,740.60 = (3,660 - 1,740.60 / 1,740.60) x 100 = 110.3%
