8. The reserve requirement, open market operations, and the money supply Consider a system of banking in which the Federal Reserve uses required reserves to control the money supply (as was the case in the United States before 2008). Assume that banks do not hold excess reserves and that households do not hold currency, so the only money exists in the form of demand deposits. To further simplify, assume the banking system has total reserves of $400. Determine the money multiplier as well as the money supply for each reserve requirement listed in the following table. Reserve Requirement Simple Money Multiplier Money Supply (Percent) (Dollars) 20           10             A higher reserve requirement is associated with a    money supply.   Suppose the Federal Reserve wants to increase the money supply by $200. Maintain the assumption that banks do not hold excess reserves and that households do not hold currency. If the reserve requirement is 10%,…

2. When you discover a $20 bill in your coat pocket that you placed there last winter, you find you were unexpectedly using money as a O medium of exchange. store of value. unit of account. factor of production.

Consider a small economy with only 2 banks, DSB and TKB, in the banking industry. Both banks have to decide whether to charge high or low interest rates. If both banks charge a high interest rate, DSB will earn $200m while TKB will earn $85m. If both banks charge a low interest rate, DSB will earn $250m while TKB will earn $400m. If DSB charges a higher interest rate while TKB charges a low interest rate, DSB will earn $300m while TKB will earn $65m. If DSB charges a low interest rate while TKB charges a high interest rate, DSB will earn $75m while TKB will earn $500m. Construct the payoff matrix for the earning of both banks, apply game theory concepts and solve for the Nash equilibrium and explain whether this is a prisoner's dilemma game.
