Unit 4 - Money

Money

  • Uses of Money
    1. Medium of exchange
    2. Unit of account
    3. Store of value
  • Types of Money
    1. Commodity money
      • products
      • Ex: gold, silver
    2. Representative money
      • Ex: IOU's
    3. Fiat money
      • has value because the government says so
  • Characteristics of Money
    1. Durability
    2. Portability
    3. Visibility
    4. Uniformity
    5. Scarcity
    6. Acceptability
  • Money Supply
    • M1 Money
      • cash, coins, currency, travelers checks, demand or checkable deposits
      • 75%
      • largest component is checkable or demandable deposits - checking accounts
    • M2 Money
      • M1 money + savings account
    • M3 Money
      • M2 money + the money market account + CD's (certificate of deposit)
  • Liquidity
    • easy to convert to cash

Banking System

  • Balance Sheet
    • summarizes the financial position of the bank at a certain time
Assets (own)
Liabilities (owe)
           1.      RR (required reserves)
           2.      ER (excess reserves)
           3.      Bank property
           4.      Securities or bonds
           5.      Loans
DD (checking)
CD (checking)

Net worth or owner’s equity
    • RR + ER = DD
  • Fractional reserve banking system
    • the banks have to keep a fraction of the total money supply that is held in reserve as currency (the bank cannot loan out everything)

Money Market

  • it is the market where the Fed and the user of money interact, thus determining the nominal interest rates
  • money demand comes from households, firms, the government, and the foreign sector
  • the money supply (MS) is determined only by the Federal Reserve Bank
  • Types of Money Demand:
    1. Transaction Demand - demand for money as a medium of exchange
    2. Asset Demand - demand for money as a store of value; it is dependent upon the interest rate
  • Money Demand
    • downward sloping because at high interest rates, people are less inclined to hold money and more inclined to hold stocks and bonds
  • Money Supply
    • it is determined by the Fed because the Fed has a monopoly over money supply
    • this is why money supply has a vertical curve
    • it is also vertical because it is independent of the interest rate
Expansionary Monetary Policy
Contractionary Monetary Policy
         ·         MS will shift to right
         ·         i (↓)
         ·         discount rate (↓)
         ·         reserve ratio (↓)
         ·         buy bonds (more $)
         ·         MS increases
         ·         MS will shift to left
         ·         i (↑)
         ·         discount rate (↑)
         ·         reserve ratio (↑)
         ·         sell bonds (less $)
         ·         MS decreases

Loanable Funds

  • the market where buyers and savers meet to exchange funds at the real interest rate
  • both the demand and the supply for loanable funds comes from households, firms, the government, and the foreign sector

Unit 3 - Fiscal Policy

Fiscal Policy

  • changes in the expenditures or tax revenues of the federal government
    • 2 tools of fiscal policy
      • Taxes - government can increase or decrease taxes
      • Spending - government can increase or decrease spending
    • fiscal policy is enacted to promote our nation's economic goals; full employment, price stability, economic growth

Deficit, Surpluses, and Debt

  • Balanced Budget
    • revenues = expenditures
  • Budget Deficit
    • revenues < expenditures
  • Budget Surplus
    • revenues > expenditures
  • Government Debt
    • sum of all deficits - sum of all surpluses
  • government must borrow money when it runs a deficit
  • government borrows from
    • individuals
    • corporations
    • financial institutions
    • foreign entities or foreign governments

Fiscal Policy Two Options

  • Discretionary Fiscal Policy (action)
    • Expansionary Fiscal Policy - think deficit
    • Contractionary Fiscal Policy - think surplus
  • Non-Discretionary Fiscal Policy (no action)

Discretionary v. Automatic Fiscal Policies

  • Discretionary
    • Increasing or decreasing government spending and/or taxes in order to return the economy to full employment. Discretionary policy involves policy makers doing fiscal policy in response to an economic problem.
  • Automatic
    • Unemployment compensation and marginal tax rates are examples of automatic policies that help mitigate the effects of recession and inflation. Automatic fiscal policy takes place without policy makers having respond to current economic problems.

Contractionary vs. Expansionary Fiscal Policy

  • Contractionary Fiscal Policy - policy designed to decrease aggregate demand
    • strategy for controlling inflation
  • Expansionary Fiscal Policy - policy designed to increase aggregate demand
    • strategy for increasing GDP, combating a recession, and reducing unemployment

Expansionary Fiscal Policy

  • recession is countered with expansionary policy
    • increase government spending (G↑)
    • decrease taxes (G↓)

Contractionary Fiscal Policy

  • inflation is countered with contradictory policy
    • decrease government spending (G↓)
    • increase taxes (G↑)

Automatic or Built-In Stabilizers

  • anything that increases the government's budget deficit during a recession and increases its budget surplus during inflation without requiring explicit action by policymakers
  • Transfer Payments:
    • Welfare checks
    • Food stamps
    • Unemployment checks
    • Corporate dividends
    • Social security
    • Veteran's benefits

Tax Systems

  • Progressive Tax System
    • average tax rate (tax revenue/GDP) rises with GDP
  • Proportional Tax System
    • average tax rate remains constant as GDP changes
  • Regressive Tax System
    • average tax rate falls with GDP

Unit 3 - Multipliers

The Spending Multiplier Effect

  • an initial change in spending (C, Ig, G, Xn) causes a larger change in aggregate spending, or aggregate demand (AD)
  • Multiplier = change in AD / change in spending
  • Multiplier = (Δ AD) / (Δ C, Ig, G, or Xn)
  • Why does this happen?
    • expenditures and income flow continuously which sets off a spending increase in the economy

Calculating the Spending Multiplier

  • the Spending Multiplier can be calculated from the MPC or the MPS
  • Multiplier = 1 / (1 - MPC) or 1 / MPS
  • Multipliers are (+) when there is an increase in spending and (-) when there is a decrease

Calculating the Tax Multiplier

  • when the government taxes, the multiplier works in reverse
  • Why?
    • because now money is leaving the circular flow
  • Tax Multiplier (note: it's negative) = (-MPC) / (1 - MPC) or (-MPC) / (MPS)
  • if there is a tax-cut, then multiplier is (+), because there is now more money in the circular flow

Unit 7 - Comparative & Absolute Advantage

Absolute Advantage looks at who can produce more with the same resources or who can produce the same output with less resources ex: Pap...
