EghtesadOnline: The average Producer Price Index for electricity in the 12-month period ending Dec. 21, 2017, which marks the end of fall, declined by 3.43% compared with the same period of last year and 2.52% compared to the same announcement in summer, the Statistical Center of Iran reported.
The PPI (using 2011 as the base year) for electricity stood at 113.02 in fall, indicating a 14.16% decrease compared to the previous quarter (summer) and 11.92% decrease over the same quarter of last year. The importance of PPI lies in its predictive content for the future pattern of Consumer Price Index. Changes in PPI are usually reflected in Consumer Price Index within a short period of time. PPI gauges price fluctuations in goods and services for the producer whereas CPI measures changes in the price level of a basket of consumer goods and services purchased by households, according to Financial Tribune.
