Credit is the trust which allows one party to provide resources to another party where that second party does not reimburse the first party immediately (thereby generating a debt), but instead arranges either to repay or return those resources (or other materials of equal value) at a later date. The resources provided may be financial, or they may consist of goods or services. Credit encompasses any form of deferred payment.
LIQUIDITY 資產流動性
定義：the ease with which an asset can be converted into the economy's medium of exchange (即資產能夠輕易轉變成交易媒介)
Note: LIQUIDATION, liquidate (v.) to close a business and sell everything it owns in order to pay debts
INTEREST RATE 利率
定義：An interest rate is the rate at which interest is paid by a borrower for the use of money that they borrow from a lender.
利率是掌控貨幣狀況的重要工具，提升利率可以用來抑制通貨膨脹，降低利率則可以用來刺激經濟活動。當利率升高的時候，借錢要償金就會升高，因此人們的錢變少了，商品也必須降低價格以吸引消費者。相對地，利率低的時候，借貸條件會變得容易，因此可以活絡經濟。
