( Please write down your answers as clearly as possible. If I can’t read your hand-writing, I never assume your answers are right )1What factors determine a banks holdings of excess reserves? How does a change in each factor affect excess reserves, the money multiplier, and the money supply?Answer: An increase in market interest rates reduces excess reserves because banks profit from increase lending. An increase in expected deposit outflows increases excess reserves. Anincrease in interest rates reduces excess reserves, increasing the multiplier and the moneysupply. An increase in expected outflows increases excess reserves, reducing themultiplier and the money supply.2Explain three ways by which the Federal Reserve System can increase the monetary base. Why is the effect of Federal Reserve actions on bank reserves less exact than the effect on the monetary base?Answer: The Fed can increase the monetary base by purchasing government bonds and foreign currency deposits, and by extending discount loans. If the person selling the securitychooses to keep the proceeds in currency, bank reserves do not increase. Because the Fedcannot control the distribution of the monetary base between reserves and currency, it hasless control over reserves than the base.3Assume that a customer deposits $1000 in her bank. Show in a T-account the effect of this deposit.If the bank is subject to reserve requirements, show in a second T-account the banks balance sheet indicating required and excess reserve. In a third T-account, show the change in the bank’s balance sheet when the bank makes loans with the excess reserves.Answer:4Demonstrate graphically the effect of an increase in the personal savings rate. Show and explain the effect of increased savings on bond prices and interest rates. How would this change affect capital spending?Answer: A graph of bond supply and demand should show an increase in bond demand. The increase in bond prices and the fall in the interest rates should be clearly shown andexplained. The increase in saving lowers interest rates, thus increasing capital spending.5Explain the concepts of asymmetric information, adverse selection, and moral hazard. When do adverse selection and moral hazard become relevant to the lending process? How has the financial system developed to deal with these problems?Answer: Asymmetric information is uneven information, which creates the problems of adverse selection and moral hazard. Adverse selection is having a disproportionate number ofhigh-risk loan applications. Moral hazard is the risk that the borrower will engage in riskybehavior after the loan is made. Adverse selection is a problem before a loan is made, andmoral hazard is a problem that exists after a loan is made. Financial intermediaries developthe expertise to screen and monitor loans, overcoming these problems. Regulations requiretimely provision of information.Page 8。
