CHAPTER 4 MONEY-TIME RELATIONSHIPS AND EQUIVALENCE

MONEY Medium of Exchange -- Means of payment for goods or services; What sellers accept and buyers pay ; Store of Value -- A way to transport buying power from one time period to another; Unit of Account -- A precise measurement of value or worth; Allows for tabulating debits and credits; Medium of Exchange -- Means of payment for goods or services; What sellers accept and buyers pay ; Store of Value -- A way to transport buying power from one time period to another; Unit of Account -- A precise measurement of value or worth; Allows for tabulating debits and credits;

CAPITAL Wealth in the form of money or property that can be used to produce more wealth.

KINDS OF CAPITAL Equity capital is that owned by individuals who have invested their money or property in a business project or venture in the hope of receiving a profit. Debt capital, often called borrowed capital, is obtained from lenders (e.g., through the sale of bonds) for investment. Equity capital is that owned by individuals who have invested their money or property in a business project or venture in the hope of receiving a profit.

INTEREST The fee that a borrower pays to a lender for the use of his or her money. INTEREST RATE The percentage of money being borrowed that is paid to the lender on some time basis. The fee that a borrower pays to a lender for the use of his or her money. INTEREST RATE The percentage of money being borrowed that is paid to the lender on some time basis.

SIMPLE INTEREST The total interest earned or charged is linearly proportional to the initial amount of the loan (principal), the interest rate and the number of interest periods for which the principal is committed. When applied, total interest “I” may be found by I = ( P ) ( N ) ( i ), where –P = principal amount lent or borrowed –N = number of interest periods ( e.g., years ) –i = interest rate per interest period The total interest earned or charged is linearly proportional to the initial amount of the loan (principal), the interest rate and the number of interest periods for which the principal is committed. When applied, total interest “I” may be found by I = ( P ) ( N ) ( i ), where –P = principal amount lent or borrowed –N = number of interest periods ( e.g., years ) –i = interest rate per interest period

ECONOMIC EQUIVALENCE Established when we are indifferent between a future payment, or a series of future payments, and a present sum of money. Considers the comparison of alternative options, or proposals, by reducing them to an equivalent basis, depending on: –interest rate; –amounts of money involved; –timing of the affected monetary receipts and/or expenditures; –manner in which the interest, or profit on invested capital is paid and the initial capital is recovered.
