Chapter 24-level of difficulty 2/3

Chapter 24 was about measuring the costs of living. That involving the consumer price index also known as CPI. The CPI demonstrates what the typical consumer is buying, or the overall costs of goods and services. In order to calculate the CPI there must be a fixed basket, where the prices for each of the goods is found, then after all the smaller individual costs are found the basket's price is found. There must be a base year in order to find such calculations. The inflation rate can then be determined after the CPI is computed. Housing, transportation and food take up majority of the costs that are paid by consumers. Then there is the Producer price index, or PPI. Which is simply what the producers/firms typically buy. A leading indicator includes that when the PPI rises then the CPI follows. Typically due to the fact that producers then pass on the costs to consumers. Although calculations can be made there are problems in the measuring cost of living. Those including the substitution bias,an introduction of new goods and the unmeasured quality change. The GDP deflator is a ratio of nominal GDP to real GDP, where prices of all goods are produced domestically. The CPI includes the prices of goods and services by producers.  Indexation is an automatic correction by law/contract of dollar amount. Including effects of inflation, or COLA. There is a difference when dealing with real and nominal interest rates where real includes the corrected effects of inflation and nominal does not.
