Unchanged a single price, operating on the territory of the entire country, must reflect the cost of production for any period of time. Comparable prices are necessary to account for the efficiency of use of production funds, growth of commodity and gross output in value and volume terms, as well as taking into account the growth of labour productivity in different categories of management. Usually prices are revised once in 10 years.
In constant prices does not reflect the dynamics of cost of production, and its natural expression, then there are plenty of consumer value. The price here is as a means of commensuration and bring to one common denominator those products that are commensurate in kind.
If you compare the output of two consecutive years, for a comparable price you can take the price of any year. In the case of analysis of dynamic series of indicators over a longer period as a comparable price takes the price of the base year that precedes the year of major changes in the price system. For bringing the prices into a comparable form is necessary to apply individual and average indices of changes in prices, and this means that constant prices should be calculated on the basis of application installed officially deflators.
To indexes-deflators are:
the index for capital construction;

- the consumer price index;

- price index of manufactured industrial products;

- the index of purchase prices of material and technical resources of industrial enterprises.
To put the price of a past year to the current price, you need to know the price index and multiply the price last year a well-known index. The result will be necessary.
The mismatch factor of the volume can degrade the rating of the organization to reduce the costs of production gross production and if you compare the actual costs with the planned costs, the difference is caused by the indicators and changes in the cost of certain products and changes in production volume. Below the indicators are comparable, it is necessary to neutralize the effect of volume, for which planned costs are translated into actual output and compares with actual costs.
