GENERAL PRICE DEFLATION A decrease in the average price paid for goods and services, resulting in an increase in the purchasing power of money. CONSUMER PRICE INDEX (CPI) One measure of price changes in our economy An estimate of general price inflation Tabulated by the Government A composite price index that measures price changes in food, shelter, medical care, transportation, apparel, and other selected goods and services used by average individuals and families CONSUMER PRICE INDEX CPI is a Laspeyres type index Las CPIk = (Qk-1 x Pk) / (Qk-1 x Pk-1) ( ( Qk-1 = Preceding (base) year quantities Pk = Current-year prices CurrentPk-1 = Preceding (base) Year Prices CPI Annual Inflation Rate = [ (CPIk - CPIk-1) / CPIk-1 ] x 100 (CPI CPIk = Consumer price index for the current year CPIk-1 = Consumer price index for the preceding year OTHER INFLATION INDICATORS The CPI shows how the prices that consumers pay The change from year to year or month to month The PPI (Producer Price Index) shows how the prices paid to producers change from year to year or month to month The Implicit Price Deflator or GDP deflator shows how all prices in the economy change from one time period to another time period INFLATIONINFLATION-RELATED TERMINOLOGY Actual Turkish Liras (ATL) - (Current time frame) cash-flow TL) cashLiras : also current Liras, nominal Liras, or inflated Liras Liras, Liras, Real Turkish Liras (RTL) - Liras in terms of purchasing power TL) at some stated time period (i.e., base year): also constant Liras Base period (b) - Purchasing-power time reference Purchasing General price inflation ( f ) - Measure of change in purchasing power from one time to another Combined (nominal) interest rate ( ic) - Market interest rate: actual Liras paid for use of capital Real interest rate - (ir) - Inflation-free interest rate: real Liras Inflationpaid for use of capital RELATING ACTUAL LIRAS TO REAL LIRAS IRAS LIRAS Use the following to convert actual Liras, as of time k, Liras, to real Liras of constant purchasing power (RTL)K = (ATL)K [1/ (1+f)]K-b TL) (ATL) = (ATL)K(P / F, f %, k-b) (ATL) k In the base period, purchasing power of actual Lira and real Lira are the same Ex.: Suppose that your salary is 45,000 TL in year one, will increase at 4% per year through year four. Compute the real dollar equivalents (base time period being year 3), assuming that the general price inflation rate is 6% per year. RELATING COMBINED AND REAL INTEREST RATES AND GENERAL INFLATION RATE ir=(ic-f)/(1+f) Similarly, current-dollar internal rate currentof return is related to the real rate of return in the following way: IRR r = (IRR c - f ) / ( 1 + f ) Ex.: Suppose that your salary is 45,000 TL in year one, will increase at 4% per year through year four. Compute the real dollar equivalents (base time period being year 3), assuming that the general price inflation rate is 6% per year. Q: What is the base-year equivalent worth of the basefourfour-year actual and real salary cash flows at the end of year one if your personal MARRc is 10% per year (ic) ?
