  • It is an idea - a very powerful one.
    So powerful we all believe in it and it became a social construct (institutionalized).

A Historical Perspective: Goldsmiths

Because they had what amounted to "extra" gold sitting around, goldsmiths gradually realized that they could lend out some of this gold without any fear of running out of gold. Why would they do this? Because instead of just keeping their gold idly in their vaults, they could earn interest on loans. Something subtle, but dramatic, happened at this point.

  • What happened?

  • The goldsmiths changed from mere depositories (depothouders) for gold into banklike institutions that had the power to create money. 

The central bank.

ECB, Bank of England, Bank of Japan, FED all central banks.

The FED is the central Bank of the United States. Central Banks are sometimes known as bankers banks because only banks (and occasionally foreign governments) can have accounts in them. As a private citizen, you cannot go to the nearest branch of the FED and open a checking account or apply to borrow money.

  • What are the central Banks responsible for?

  • Print Banknotes.

  • Supervision over the bigger banks.

  • Targeting inflation.

  • Monetary policy.

  • Define M1 and M2 money:

  • M1 = Cash + Demand deposists (debit card).

  • M2 = M1 + Near money (like your savings account.

Inflation can be moderated by the Central Bank.

  • When the Central Bank wants to slow down the economy. What does the Central Bank do?

  • It increases interest rates (expensive to borrow money).

  • Name the three instruments of a Central Bank:

  1. Changing the reserve requirement (quantity of money).

  2. Changing the discount rate (the price of money).

  3. Open market operations.

  • What is an Expansionary fiscal policy?

  • A form of macroeconomic policy that seeks to encourage economic growth.


An expansionary policy can consist of either monetary policy or fiscal policy (or a combination of the two). It is part of the general policy prescription of Keynesian economics, to be used during economic slowdowns and recessions in order to moderate the downside of economic cycles.

  • What does a contractionary policy refer to?

  • Contractionary policy is a monetary measure referring either to a reduction in government spending—particularly deficit spending—or a reduction in the rate of monetary expansion by a central bank.

  • What does a contractionary policy?

  • It is a type of macroeconomic tool designed to combat rising inflation or other economic distortions created by central banks or government interventions.

By far the most significant of the Fed's tools for controlling the supply of money is open market operations.

  • Explain the Fed's Open Market operations:

  • The purchases and sale by the Fed of government securities in the open market; a tool used to expand or contract the number of reserves in the system and thus the money supply.

  • What are excess reserves?

  • The difference between a bank's actual reserves and its required reserves.
