Technical Notes


Consumer Price Index (CPI) is an indicator of change in the average retail prices of a fixed    basket of goods and services commonly purchased by households relative to a base year. It measures how much on the average, prices of goods and services have   increased or decreased from a particular reference period. 

Purchasing Power of Peso (PPP) shows how much the peso in the base period is worth in another period. It gives an indication of the real value of the peso in a given period relative to the peso value in the base period.  Purchasing Power of Peso (PPP) is inversely related to inflation rate. Thus, as inflation rate increases, PPP declines.
