тоись опять таки используется в задаче с двумя трубами и бочкой, чтобы оценить и подкорректировать монетарную политику центробанка.The CPI also has a number of specific applications:
(1) It is used to escalate a given dollar value, over time, to preserve the purchasing power of that value. Thus, the CPI is widely used to adjust contracted payments, such as wages, rents, leases and child or spousal support allowances. Private and public pension programs (Old Age Security and the Canada Pension Plan), personal income tax deductions, and some government social payments are also escalated using the CPI.
(2) It is used as a deflator of various economic aggregates, either of income flows, to obtain constant dollar estimates of income, or of expenditure flows, to obtain personal expenditure estimates at constant prices.
(3) It is used to set and monitor the implementation of economic policy. The Bank of Canada, for example, uses the CPI, and special aggregates of the CPI, to monitor its monetary policies.
(4) Business analysts and economists use the CPI for economic analysis and research on various issues, such as the causes and effects of inflation, and understanding regional disparities in price movements.
