Econ 3300

1. Consider a bank that has the following balance sheet



Liabilities and Net Worth

Reserves                           $100

Demand deposits          $1,000

Loans                            $1,000

Net worth                           100


A new customer opens a checking account and deposits $500 into it. For each of the following questions, assuming the required reserve ratio is 10 percent.

(A). After the new deposit, how much money can this bank lend?
