[简答题]One might ask why speculation is permitted when there is so real a danger of loss. The basic reason is that speculation can perform useful functions in the market equilibrium and encourages faster entry of more suppliers. If the price change lagged until after an actual commodity shortage had occurred, the fluctuation would probably be sharper and more sudden. Remedial supply action could not be further delayed. Similarly, if speculators foresee a surplus in some commodity, their selling of futures will help drive the price down to some extent before the surplus actually occurs. When speculators foresee a shortage and bid up the price, they are also helping to conserve the present supply.

[简答题]Expansion of Money by Banks
Banks are permitted to create money out of "multiple expansion of bank deposits." They generate about five dollars of new money for every dollar of reserves. Let us suppose that a person brings $100 into a bank for deposit. If the bank were to hold 100 percent reserves, it would keep the total amount in the vault. However, as we have learned, the law requires that only a small percentage be kept. Let us assume the amount required at this time is 20 percent. With the $80 that does not have to be deposited with the Federal Reserve, the bank may buy government bonds and lend the money, thus assisting business expansion, making mortgages on property, and the like. Note that the depositor still has $100 in the bank, but the bank, in turn, has created $80 of new money by lending it.
The person who borrowed the $80 will probably deposit some or all of the money in the same bank or in some other bank: what is not deposited immediately
