The Producer Input Prices indicator is defined as the change in the prices of components and semifinished products in the industry (the growing "input" prices may have no influence on the inflation index, as there can be reduction of costs in the production process). It is a string indicator of inflation. From the total value of the indicator, usually a part is singled out which does not take into account the price of food, alcohol, tobacco and fuel (prices for these commodities are highly volatile). The indicator is taken into account by the market.
