Concise Summary of Money, Price Levels, and Inflation Concepts

Important Concepts

  • What is Money? A fundamental concept in economics, referring to assets that are accepted in exchange for goods and services.
  • M1 and M2:
    • M1 = Currency held + Chequable deposits
    • M2 = M1 + Non-chequable deposits + Fixed term deposits
  • Monetary Base: The total of all notes, coins, and bank deposits at the central bank.
  • Money Creation Process: Involves banks creating money by lending, influenced by factors such as reserve ratios and currency drains.

Monetary Policies

  • Bank of Canada’s Balance Sheet: Shows the assets and liabilities of the central bank.
  • Policy Tools:
    • Open Market Operations: Buying/selling government securities.
    • Bank Rate: The interest rate on loans from the central bank to commercial banks.

Key Formulas

  • Money Multiplier: MM = \frac{(1 + C/D)}{(C/D + R/D)}
  • Demand for Money: Governed by factors like income and interest rates.

Money Market Equilibrium

  • Occurs when the supply of money equals the demand for money. Changes in monetary policy can shift the equilibrium.

Aggregate Demand and Supply

  • AD Curve: Slopes downward due to the wealth effect and substitution effects.
  • Fiscal and Monetary Policies can influence aggregate demand through changes in government spending and interest rates.

Inflation and Stagflation

  • Inflation occurs when money supply increases faster than potential GDP. Stagflation refers to simultaneous high inflation and unemployment.

Multiplier Effect

  • A change in spending causes a larger change in national income. The formula is Multiplier = \frac{1}{1 - MPC} ,
    where MPC is the marginal propensity to consume.

Practice Problems

  • Calculate changes in M1 and M2 based on withdrawals and deposits.
  • Understanding impacts of trades and interest rates on currency values in foreign exchange.
