Fiscal Policy:
The Multiplier Effect
Changes in spending ripple through the economy to generate event larger changes in real GDP. This is called the multiplier effect.
1.Multiplier = change in real GDP / initial change in spending. Alternatively, it can be rearranged to read Change in real GDP = initial change in spending x multiplier.
2.Three points to remember about the multiplier:
a.The initial change in spending is usually associated with investment because it is so volatile, but changes in consumption (unrelated to income), net exports, and government purchases also are subject to the multiplier effect.
b.The initial change refers to an upshift or downshift in the aggregate expenditures schedule due to a change in one of its components, like investment.
c.The multiplier works in both directions (up or down).
B.The multiplier is based on two facts.
1.The economy has continuous flows of expenditures and income—a ripple effect—in which income received by Grant comes from money spent by Battaglia. Battaglia’s income, in turn, came from money spent by Mendoza, and so forth.
2.Any change in income will cause both consumption and saving to vary in the same direction as the initial change in income, and by a fraction of that change.
a.The fraction of the change in income that is spent is called the marginal propensity to consume (MPC).
b.The fraction of the change in income that is saved is called the marginal propensity to save (MPS).
C.The size of the MPC and the multiplier are directly related; the size of the MPS and the multiplier are inversely related. In equation form Multiplier = 1 / MPS or 1 / (1-MPC).
D.The significance of the multiplier is that a small change in investment plans or consumption-saving plans can trigger a much larger change in the equilibrium level of GDP.
E.The simple multiplier given above can be generalized to include other “leakages” from the spending flow besides savings. For example, the actual multiplier is derived by including taxes and imports as well as savings in the equation. In other words, the denominator is the fraction of a change in income not spent on domestic output.
One major function of the government is to stabilize the economy (prevent unemployment or inflation).
Stabilization can be achieved in part by manipulating the public budget—government spending and tax collections—to increase output and employment or to reduce inflation.
Discretionary fiscal policy refers to the deliberate manipulation of taxes and government spending by Congress to alter real domestic output and employment, control inflation, and stimulate economic growth. “Discretionary” means the changes are at the option of the Federal government.
Discretionary fiscal policy changes are often initiated by the President, on the advice of the Council of Economic Advisers (CEA).
Changes not directly resulting from congressional action are referred to as nondiscretionary (or “passive”) fiscal policy.
Fiscal policy choices: Expansionary fiscal policy is used to combat a recession. Contractionary fiscal policy is needed to combat an inflation
Policy options: G or T?
1.Economists tend to favor higher G during recessions and higher taxes during inflationary times if they are concerned about unmet social needs or infrastructure.
2.Others tend to favor lower T for recessions and lower G during inflationary periods when they think government is too large and inefficient.
A.Problems of timing
1.Recognition lag is the elapsed time between the beginning of recession or inflation and awareness of this occurrence.
2.Administrative lag is the difficulty in changing policy once the problem has been recognized.
3.Operational lag is the time elapsed between change in policy and its impact on the economy.
B.Political considerations: Government has other goals besides economic stability, and these may conflict with stabilization policy.
- A political business cycle may destabilize the economy: Election years have been characterized by more expansionary policies regardless of economic conditions.
2.State and local finance policies may offset federal stabilization policies. They are often procyclical, because balanced-budget requirements cause states and local governments to raise taxes in a recession or cut spending making the recession possibly worse. In an inflationary period, they may increase spending or cut taxes as their budgets head for surplus.
3.The crowdingout effect may be caused by fiscal policy.
a.“Crowdingout” may occur with government deficit spending. It may increase the interest rate and reduce private spending which weakens or cancels the stimulus of fiscal policy.
b.Some economists argue that little crowding out will occur during a recession.
c.Economists agree that government deficits should not occur at F.E., it is also argued that monetary authorities could counteract the crowdingout by increasing the money supply to accommodate the expansionary fiscal policy.
- Current thinking on fiscal policy
- Some economists oppose the use of fiscal policy, believing that monetary policy is more effective or that the economy is sufficiently self-correcting.
- Most economists support the use of fiscal policy to help “push the economy” in a desired direction, and using monetary policy more for “fine tuning.”
3.Economists agree that the potential impacts (positive and negative) of fiscal policy on long-term productivity growth should be evaluated and considered in the decision-making process, along with the short-run cyclical effects.
Monetary Policy / The Fed / Banking
Although we are fascinated by large sums of currency, people use checkable deposits for most transactions.
A.Most transaction accounts are “created” as a result of loans from banks or thrifts.
B.This chapter demonstrates the moneycreating abilities of a single bank or thrift and then looks at that of the system as a whole.
C.The term depository institution refers to banks and thrift institutions, but in this chapter the term bank will be often used generically to apply to all depository institutions.
The Fractional Reserve System: The Goldsmiths
A.Banks in the U.S. and most other countries are only required to keep a percentage (fraction) of checkable deposits in cash or with the central bank.
B.In the 16th century goldsmiths had safes for gold and precious metals, which they often kept for consumers and merchants. They issued receipts for these deposits.
C.Receipts came to be used as money in place of gold because of their convenience, and goldsmiths became aware that much of the stored gold was never redeemed.
D.Goldsmiths realized they could “loan” gold by issuing receipts to borrowers, who agreed to pay back gold plus interest.
E.Such loans began “fractional reserve banking,” because the actual gold in the vaults became only a fraction of the receipts held by borrowers and owners of gold.
F.Significance of fractional reserve banking:
1.Banks can create money by lending more than the original reserves on hand. (Note: Today gold is not used as reserves).
2.Lending policies must be prudent to prevent bank “panics” or “runs” by depositors worried about their funds. Also, the U.S. deposit insurance system prevents panics.
A Single Commercial Bank
A.A balance sheet states the assets and claims of a bank at some point in time.
B.All balance sheets must balance, that is, the value of assets must equal value of claims.
1.The bank owners’ claim is called net worth.
2.Nonowners’ claims are called liabilities.
3.Basic equation: Assets = liabilities + net worth.
1.Terminology: Actual reserves minus required reserves are called excess reserves.
2.Control: Required reserves do not exist to protect against “runs,” because banks must keep their required reserves. Required reserves are to give the Federal Reserve control over the amount of lending or deposits that banks can create. In other words, required reserves help the Fed control credit and money creation. Banks cannot loan beyond their excess reserves.
3.Asset and liability: Reserves are an asset to banks but a liability to the Federal Reserve Bank system, since now they are deposit claims by banks at the Fed.
G.Profits, liquidity, and the federal funds market:
1.Profits: Banks are in business to make a profit like other firms. They earn profits primarily from interest on loans and securities they hold.
2.Liquidity: Banks must seek safety by having liquidity to meet cash needs of depositors and to meet check clearing transactions.
3.Federal funds rate: Banks can borrow from one another to meet cash needs in the federal funds market, where banks borrow from each other’s available reserves on an overnight basis. The rate paid is called the federal funds rate.
The Banking System: MultipleDeposit Expansion
The entire banking system can create an amount of money which is a multiple of the system’s excess reserves, even though each bank in the system can only lend dollar for dollar with its excess reserves.
B.Three simplifying assumptions:
1.Required reserve ratio assumed to be 20 percent. (The actual reserve ratio averages 10 percent of checkable deposits.)
2.Initially banks have no excess reserves; they are “loaned up.”
3.When banks have excess reserves, they loan it all to one borrower, who writes check for entire amount to give to someone else, who deposits it at another bank. The check clears against original lender.
C.System’s lending potential: Suppose a junkyard owner finds a $100 bill and deposits it in Bank A. The system’s lending begins with Bank A having $80 in excess reserves, lending this amount, and having the borrower write an $80 check which is deposited in Bank B.
D.Monetary multiplier
1.Formula for monetary or checkable deposit multiplier is:
Monetary multiplier = 1/required reserve ratio or m = 1/R or 1/.20 in our example.
2.Maximum deposit expansion possible is equal to: excess reserves monetary multiplier, or
3.Higher reserve ratios generate lower money multipliers.
a.Changing the money multiplier changes the money creation potential.
b.Changing the reserve ratio changes the money multiplier but be careful! It also changes the amount of excess reserves that are acted on by the multiplier. Cutting the reserve ratio in half will more than double the deposit creation potential of the system.
E.The process is reversible. Loan repayment destroys money, and the money multiplier increases that destruction.
The Bank Panics of 1930-1933
A.Bank panics in 193033 led to a multiple contraction of the money supply, which worsened Depression.
B.Many of failed banks were healthy, but they suffered when worried depositors panicked and withdrew funds all at once. More than 9000 banks failed in three years.
C.As people withdrew funds, this reduced banks’ reserves and, in turn, their lending power fell significantly.
D.Contraction of excess reserves leads to multiple contraction in the money supply, or the reverse of situation in Table 13.2. Money supply was reduced by 25 percent in those years.
E.President Roosevelt declared a “bank holiday,” closing banks temporarily while Congress started the Federal Deposit Insurance Corporation (FDIC), which ended bank panics on insured accounts.
Functions of Money
A.Medium of exchange: Money can be used for buying and selling goods and services.
- Unit of account: Prices are quoted in dollars and cents.
- Store of value: Money allows us to transfer purchasing power from present to future. It is the most liquid (spendable) of all assets, a convenient way to store wealth.
Components of the Money Supply
A.Narrow definition of money: M1 includes currency and checkable deposits
1.Currency (coins + paper money) held by public. (54% of M1)
a.Is “token” money, which means its intrinsic value is less than actual value. The metal in a dime is worth less than 10¢.
b.All paper currency consists of Federal Reserve Notes issued by the Federal Reserve.
2.Checkable deposits are included in M1, since they can be spent almost as readily as currency and can easily be changed into currency. (46% of M1)
a.Commercial banks are a main source of checkable deposits for households and businesses.
b.Thrift institutions (savings & loans, credit unions, mutual savings banks) also have checkable deposits.
3.Qualification: Currency and checkable deposits held by the federal government, Federal Reserve, or other financial institutions are not included in M1.
B.Money Definition: M2 = M1 + some near-monies which include:
- Savings deposits and money market deposit accounts.
- Small time deposits (certificates of deposit) less than $100,000.
- Money market mutual fund balances, which can be redeemed by phone calls, checks, or through the Internet.
Are Credit Cards Money?
Credit cards are not money, but their use involves shortterm loans; their convenience allows you to keep M1 balances low because you need less for daily purchases.
The Federal Reserve and the Banking System
- The Federal Reserve System (the “Fed”) was established by Congress in 1913 and holds power over the money and banking system.
- The central controlling authority for the system is the Board of Governors and has seven members appointed by the President for staggered 14year terms. Its power means the system operates like a central bank.
- The Federal Open Market Committee (FOMC) includes the seven governors plus five regional Federal Reserve Bank presidents whose terms alternate. They set policy on buying and selling of government bonds, the most important type of monetary policy, and meet several times each year.
4.The system has twelve districts, each with its own district bank and two or three branch banks. They help implement Fed policy and are advisory.
a.Each is quasipublic: It is owned by member banks but controlled by the government’s Federal Reserve Board, and any profits go to the U.S. Treasury.
b.They act as bankers’ banks by accepting reserve deposits and making loans to banks and other financial institutions. In making loans, the Federal Reserve is the “lender of last resort,” meaning that the Fed is available to lend money should other avenues (e.g. other commercial banks) not be available.
3.About 7,600 commercial banks existed in 2006. They are privately owned and consist of state banks (threefourths of total) and large national banks (chartered by the Federal government).
B.Functions of the Fed and money supply:
1.The Fed issues “Federal Reserve Notes,” the paper currency used in the U.S. monetary system.
2.The Fed sets reserve requirements and holds the reserves of banks and thrifts not held as vault cash.
3.The Fed may lend money to banks and thrifts, charging them an interest rate called the discount rate.
4.The Fed provides a check collection service for banks (checks are also cleared locally or by private clearing firms).
5.Federal Reserve System acts as the fiscal agent for the Federal government.
6.The Federal Reserve System supervises member banks.
7.Monetary policy and control of the money supply is the “major function” of the Fed.
C.Federal Reserve independence is important but is also controversial from time to time. Advocates of independence fear that more political ties would cause the Fed to follow expansionary policies and create too much inflation, leading to an unstable currency such as that in other countries.
